Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies a. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Sientra, Inc. (“Sientra”, the “Company”, “we”, “our”, or “us”) in this Quarterly Report on Form 10-Q have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. Accordingly, they do not include certain footnotes and financial presentations normally required under accounting principles generally accepted in the United States of America for complete financial reporting. The interim financial information is unaudited, but reflects all normal adjustments and accruals which are, in the opinion of management, considered necessary to provide a fair presentation for the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 31, 2022, or the Annual Report. The results for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year or period. As a result of the miraDry Sale discussed in Note 2, the miraDry business met the criteria to be reported as discontinued operations. Therefore, the Company is reporting the historical results of miraDry, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations for all periods presented herein through the date of the Sale. Unless otherwise noted, the accompanying notes to the unaudited condensed consolidated financial statements have all been revised to reflect continuing operations only. Following the Sale the Company has one operating segment in continuing operations named Plastic Surgery, formerly known as Breast Products. b. Liquidity and Going Concern The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with generally accepted accounting principles in the United States of America. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Since the Company’s inception, it has incurred recurring losses and cash outflows from operations and the Company anticipates that losses will continue in the near term. During the six months ended June 30, 2022, the Company incurred net losses of $ 36.3 million and used $ 31.0 million of cash in operations. As of June 30, 2022, the Company had cash and cash equivalents of $ 25.0 million, with the ability to receive $ 14.0 million on the term loan pursuant to the credit agreement with MidCap Financial Trust. These conditions raise substantial doubt about the Company's ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. In an effort to alleviate these conditions, management is currently evaluating various funding alternatives to improve liquidity and may seek to raise additional capital from the sale of equity securities and incremental debt financing. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry. These unaudited condensed financial statements do not include any adjustments relating to the carrying amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern. c. Recent Accounting Pronouncements Recently Adopted Accounting Standards In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The amendment provides optional expedients and exceptions for contract modifications that replace a reference rate affected by reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022, and entities may elect to apply by Topic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The Company adopted the applicable amendments within ASU 2020-04 prospectively in the second quarter of 2022 and there was no material impact on its condensed consolidated financial statements from the adoption. Recently Issued Accounting Standards In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . The amendment eliminates certain accounting models and simplifies the accounting for convertible instruments and enhances disclosures for convertible instruments and earnings per share. The amendments are effective for public entities excluding smaller reporting companies for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years and early adoption is permitted. The Company is currently evaluating the impact that adoption of the standard will have on the condensed consolidated financial statements. d. Risks and Uncertainties As an aesthetics company, surgical procedures involving the Company’s breast products are susceptible to local and national government restrictions, such as social distancing, vaccination requirements, “shelter in place” orders and business closures. In addition, some treatment facilities have reduced staffing and postponed certain non-emergency procedures in response to COVID-19 or diverted resources to treat those patients with COVID-19. The Company anticipates that an increase a continuing shortage in staff, especially nurses, at hospitals across the U.S. due to the impact of COVID-19 may also lower number of non-emergency procedures performed. The inability or limited ability to perform such non-emergency procedures and patients electing to postpone elective aesthetics procedures due to the pandemic significantly harmed the Company’s revenues since the second quarter of 2020 and continued to harm the Company’s revenues during the six months ended June 30, 2022. While many states have lifted certain restrictions on non-emergency procedures and procedural volume rates for non-emergency procedures have been recovering, the Company will likely continue to experience future harm to its revenues while existing or new restrictions remain in place. It is not possible to accurately predict the length or severity of the COVID-19 pandemic or the impact on the Company’s business, including the timing for a broad and sustained ability to perform non-emergency procedures involving the Company’s products. The Company continues to monitor and assess new information related to the COVID-19 pandemic, the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets. Further, the spread of COVID-19 has caused the Company to modify workforce practices, and the Company may take further actions determined to be in the best interests of the Company’s employees or as required by governments. The continued spread of COVID-19, or another infectious disease, and other geopolitical conditions, could also result in delays or disruptions in the Company’s supply chain (for example, sourcing of medical-grade silicone) or adversely affect the Company’s manufacturing facilities and personnel. Further, trade and/or national security protection policies may be adjusted as a result of the COVID-19 pandemic, such as actions by governments that limit, restrict or prevent the movement of certain goods into a country and/or region, and current U.S./China trade relations may be further exacerbated by the pandemic. The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets and goodwill, and sales returns liability required could be impacted by the pandemic. While the full impact and duration of COVID-19 is unknown at this time, the Company has made appropriate estimates based on the facts and circumstances available as of the reporting date. These estimates may change as new events occur and additional information is obtained. e. Reclassifications Certain reclassifications have been made to prior year amounts to conform to the current year presentation, including those related to discontinued operations following the sale of the miraDry business.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	2. Discontinued Operations On June 10, 2021, the Company completed the sale of its miraDry business (the “Sale”) to miraDry Acquisition Company, Inc., a Delaware corporation (“Buyer”), an entity affiliated with 1315 Capital II, LP, as a result of the Company’s strategic decision to focus investment on its core Plastic Surgery segment. The Sale was made pursuant to the terms and conditions of the Asset Purchase Agreement (the “Purchase Agreement”), dated May 11, 2021, among the Company and certain of its subsidiaries, Buyer, and, solely for purposes of Section 8.14 of the Purchase Agreement, 1315 Capital II, LP. The aggregate purchase price was $ 10.0 million, which after certain adjustments for agreed upon changes in the estimated net asset value amount of purchased assets and assumed liabilities resulted in net cash proceeds of $ 11.3 million to the Company on the date of close. In October 2021, the Company finalized the transaction and paid $ 3.2 million to the Buyer in accordance with the agreed upon post close changes in the net asset value and recognized a loss on sale of $ 2.5 million. In accordance with the Purchase Agreement, assumed liabilities did not include product liabilities, environmental, and employee claims arising prior to the closing date. The Purchase Agreement also included customary representations and warranties, as well as certain covenants, including, among other things, that: (i) the Company will abide by certain non-solicitation, exclusivity, and non-competition covenants, and (ii) the Company would enter into a transition services agreement (“TSA”) to provide certain transition services related to the business. Under the TSA, the Company provided certain post-closing services to the Buyer related to the miraDry business for a period of six months , including accounting, accounts receivable support, customer service, IT, regulatory, quality assurance, and clinical support. As consideration for these services, the Buyer reimbursed the Company for direct and certain indirect costs, as well as certain overhead or administrative expenses related to operating the business. The Company recognized $ 0.1 million of TSA fees and cost reimbursements in operating expenses from continuing operations in the condensed consolidated statement of operations for the six months ended June 30, 2022 . Since the closing date, the Company has received $ 0.3 million relating to the TSA services and has recorded a receivable of $ 0.1 million within other current assets in the condensed consolidated balance sheets. In connection with the accounts receivable support under the TSA, since the closing date the Company received $ 2.3 million in customer payments and has remitted $ 2.3 million to the Buyer. As of June 30, 2022, the Company does not have a payable to the Buyer on the condensed consolidated balance sheets. Additionally, the Company and the Buyer entered into a sublease agreement whereby the Buyer subleased the miraDry office space in Santa Clara, CA. The sublease term was for an initial period of six months, with subsequent option periods for up to a total of twenty-four months. Following the initial period, the Buyer exercised an additional period of six months and an additional extension of six months thereafter. During three and six months ended June 30, 2022, the Company recognized $ 0.3 million and $ 0.5 million, respectively, of sublease income in general and administrative expenses in the condensed consolidated statements of operations.

Revenue

Revenue from Contract with Customer [Abstract]
Revenue	3. Revenue The Company generates revenue primarily through the sale and delivery of promised goods or services to customers. Sales prices are documented in the executed sales contract, purchase order or order acknowledgement prior to the transfer of control to the customer. Typical payment terms are 30 days. Revenue contracts may include multiple products or services, each of which is considered a separate performance obligation. Performance obligations typically include the delivery of promised products, such as breast implants, tissue expanders, and BIOCORNEUM, along with service-type warranties. Other deliverables are sometimes promised but are ancillary and insignificant in the context of the contract as a whole. Revenue is allocated to each performance obligation based on its relative standalone selling price. The Company determines standalone selling prices based on observable prices for all performance obligations with the exception of the service-type warranty under the Platinum20 Limited Warranty Program, or Platinum20, which is based on the expected cost plus margin approach. Inputs into the expected cost plus margin approach include historical incidence rates, estimated replacement costs, estimated financial assistance payouts and an estimated margin. The liability for unsatisfied performance obligations under the service warranty as of June 30, 2022 were as follows: Six Months Ended June 30, 2022 Balance as of December 31, 2021 $ 3,237 Additions and adjustments 1,012 Revenue recognized ( 369 ) Balance as of June 30, 2022 $ 3,880 The liability for the current portion is included in “Accrued and other current liabilities” and the long-term portion is included in “Other liabilities” in the condensed consolidated balance sheets. Revenue for service warranties are recognized ratably over the term of the agreements. Specifically for Platinum20, the performance obligation is satisfied at the time that the benefits are provided and are expected to be satisfied over the following 3 to 24 month period for financial assistance and 20 years for product replacement. For delivery of promised products, control transfers and revenue is recognized upon shipment, unless the contractual arrangement requires transfer of control when products reach their destination, for which revenue is recognized once the product arrives at its destination. A portion of the Company’s revenue is generated from the sale of consigned inventory of breast implants and tissue expanders maintained at doctor, hospital, and clinic locations. For these products, revenue is recognized at the time the Company is notified by the customer that the product has been used, not when the consigned products are delivered to the customer’s location. Sales Return Liability With the exception of the Company’s BIOCORNEUM scar management products, the Company allows for the return of products from customers within six months after the original sale, which is accounted for as variable consideration. A sales return liability is established based on estimated returns using relevant historical experience taking into consideration recent gross sales and notifications of pending returns, as adjusted for changes in recent industry events and trends. The estimated sales returns are recorded as a reduction of revenue and as a sales return liability in the same period revenue is recognized. Actual sales returns in any future period are inherently uncertain and thus may differ from the estimates. If actual sales returns differ significantly from the estimates, an adjustment to revenue in the current or subsequent period would be recorded. The following table provides a rollforward of the sales return liability (in thousands): Six Months Ended June 30, 2022 2021 Beginning balance $ 13,399 $ 9,192 Addition to reserve for sales activity 87,033 77,464 Actual returns ( 87,184 ) ( 74,905 ) Change in estimate of sales returns ( 754 ) ( 1,179 ) Ending balance $ 12,494 $ 10,572

Fair Value Measurements Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable: • Level 1 — Quoted prices in active markets for identical assets or liabilities. • Level 2 — Observable inputs (other than Level 1 quoted prices) such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques. Contingent consideration The contingent consideration balance consists of milestone payments related to the acquisition of AuraGen and future royalty payments related to the acquisition of BIOCORNEUM. The Company assessed the fair value of all contingent consideration using a Monte-Carlo simulation model. The contingent consideration related to AuraGen is based on the achievement of certain clinical endpoints following the completion of a study measuring retention rates using the fat grafting products. The significant assumptions utilized in the fair value measurement was the probable retention rate based on historical data and the Company's equity volatility of 108 %. Any subsequent changes to the fair value of contingent consideration will be recorded as an adjustment to the carrying value of the assets acquired. The contingent consideration related to the acquisition of BIOCORNEUM consists of royalty obligations based on future net sales for a defined term, beginning in 2024. The significant assumption utilized in the fair value measurement was the discount rate, which was 20.0 %. As these inputs are not observable, the overall fair value measurement of the contingent consideration is classified as Level 3. The following tables present information about the Company’s liabilities that are measured at fair value on a recurring basis as of June 30, 2022 and December 31,2021 and indicate the level of the fair value hierarchy utilized to determine such fair value (in thousands): Fair Value Measurements as of June 30, 2022 Using: Level 1 Level 2 Level 3 Total Liabilities: Liability for contingent consideration $ — $ — $ 2,805 $ 2,805 $ — $ — $ 2,805 $ 2,805 Fair Value Measurements as of December 31, 2021 Using: Level 1 Level 2 Level 3 Total Liabilities: Liability for contingent consideration $ — $ — $ 3,114 $ 3,114 $ — $ — $ 3,114 $ 3,114 The following table provides a rollforward of the aggregate fair values of the Company’s liabilities for which fair value is determined by Level 3 inputs (in thousands): Contingent consideration liability Balance, December 31, 2021 $ 3,114 Change in fair value ( 309 ) Balance, June 30, 2022 $ 2,805 The liability for the current portion of contingent consideration is included in “Accrued and other current liabilities” and the long-term portion is included in “Deferred and contingent consideration” in the condensed consolidated balance sheets.

The Third Amendment provided that the fourth tranche of $ 5,000,000 was to be drawn on March 31, 2022. Additionally, the Third Amendment provides the Company with a sixth tranche pursuant to which the Company may draw $ 9,000,000 any time after January 1, 2023 until March 31, 2023. The Third Amendment also eliminated the minimum unrestricted cash requirement and reset the minimum Net Revenue (as defined therein) requirements based on the Company’s 12-month trailing Net Revenue. Finally, the Third Amendment increased the prepayment fee by 0.5 % until following the third anniversary of the Effective Date, at which point no prepayment fee shall apply. As of June 30, 2022 , there was $ 21.0 million of outstanding principal and $ 0.3 million of an exit fee payable related to the term loans, reduced by unamortized debt issuance costs of $ 0.8 million included in "Current portion of long-term debt" and $ 0.3 million included in “Long-term debt” on the condensed consolidated balance sheets. Also on March 30, 2022, the Company entered into a Sixth Amendment (the “Sixth Amendment”) to the Revolving Loan Agreement, with certain of the Company’s wholly owned subsidiaries, the lenders party thereto and MidCap. The Sixth Amendment modified the Net Revenue (as defined therein) requirement in a manner consistent with the modification under the Restated Term Loan Agreement.

As of June 30, 2022 and December 31, 2021 , the Company had no preferred stock issued or outstanding. b. Stock Option Plans The Company’s board of directors adopted the 2014 Equity Incentive Plan, or 2014 Plan, in July 2014, and the stockholders approved the 2014 Plan in October 2014. The 2014 Plan became effective upon completion of the IPO on November 3, 2014, at which time the Company ceased granting awards under the 2007 Plan. As of June 30, 2022, a total of 1,866,579 shares of the Company’s common stock were available for issuance under the 2014 Plan. As of June 30, 2022, inducement grants for 2,342,893 shares of common stock have been awarded, and 312,943 shares of common stock were available for future issuance under the Inducement Plan. Options under the 2014 Plan may be granted for periods of up to ten years as determined by the Company’s board of directors, provided, however, that (i) the exercise price of an ISO shall not be less than 100 % of the estimated fair value of the shares on the date of grant, and (ii) the exercise price of an ISO granted to a more than 10 % shareholder shall not be less than 110 % of the estimated fair value of the shares on the date of grant.

Additionally, options have been granted to certain key executives that vest upon achievement of performance conditions based on performance targets as defined by the board of directors, which have included net sales targets and defined corporate objectives over the performance period with possible payout ranging from 0 % to 100 % of the target award. Compensation expense is recognized on a straight-lined basis over the vesting term of one year based upon the probable performance target that will be met. The vesting provisions of individual options may vary but provide for vesting of at least 25 % per year. The following summarizes all option activity under the 2007 Plan, 2014 Plan and Inducement Plan: Weighted Weighted average remaining Option exercise contractual Shares price term (year) Balances at December 31, 2021 1,703,963 $ 4.75 5.41 Granted 150,000 Forfeited ( 73,637 ) 5.10 Balances at June 30, 2022 1,780,326 $ 4.34 5.51 For stock-based awards the Company recognizes compensation expense based on the grant date fair value using the Black-Scholes option valuation model. Stock-based compensation expense related to stock options for both the three and six months ended June 30, 2022 and 2021 were $ 0.2 million and $ 0.3 million, respectively. As of June 30, 2022, unrecognized compensation costs related to stock options was $ 1.5 million. c. Restricted Stock Units The Company has issued restricted stock unit awards, or RSUs, under the 2014 Plan and the Inducement Plan. The RSUs issued to employees generally vest on a straight-line basis annually over a 3 -year requisite service period. RSUs issued to non-employees generally vest either monthly or annually over the service term. Activity related to RSUs is set forth below: Weighted Number grant date of shares fair value Balances at December 31, 2021 2,799,552 $ 8.11 Granted 3,333,797 2.22 Vested ( 596,101 ) 5.46 Forfeited ( 167,383 ) Balances at June 30, 2022 5,369,865 $ 5.00 Stock-based compensation expense for RSUs for the three months ended June 30, 2022 and 2021 was $ 1.8 million and $ 2.3 million, respectively. Stock-based compensation expense for RSUs for the six months ended June 30, 2022 and 2021 was $ 3.7 million and $ 5.2 million, respectively. As of June 30, 2022, there was $ 11.4 million of total unrecognized compensation costs related to non-vested RSU awards. The cost is expected to be recognized over a weighted average period of approximately 2.09 years. d. Employee Stock Purchase Plan The Company’s board of directors adopted the 2014 Employee Stock Purchase Plan, or ESPP, in July 2014, and the stockholders approved the ESPP in October 2014. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15 % of their eligible compensation, subject to any plan limitations. The ESPP provides for offering periods not to exceed 27 months, and each offering period will include purchase periods, which will be the approximately six-month period commencing with one exercise date and ending with the next exercise date. Employees are able to purchase shares at 85 % of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the purchase date. A total of 255,500 shares of common stock were initially reserved for issuance under the ESPP, subject to certain annual increases. During the six months ended June 30, 2022, employees purchased 139,574 shares of common stock at a weighted average price of $ 2.36 per share. As of June 30, 2022, the number of shares of common stock available for future issuance for the ESPP was 1,735,734 . The Company estimated the fair value of employee stock purchase rights using the Black-Scholes model. Stock-based compensation expense related to the ESPP was $ 0.2 million for both the three months ended June 30, 2022 and 2021. Stock-based compensation expense related to the ESPP was $ 0.3 million for both the six months ended June 30, 2022 and 2021 .

Net Loss Per Share

Earnings Per Share [Abstract]
Earnings (Loss) Per Share	9. Net Loss Per Share Basic net loss per share attributable to common stockholders is computed by dividing net loss by the weighted average number of common shares outstanding during each period. Diluted net loss per share is computed by dividing net loss available to common stockholders by the weighted average number of common shares and dilutive potential common share equivalents then outstanding, to the extent they are dilutive. Potential dilutive shares consist of shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. Dilutive net loss per share is the same as basic net loss per share for all periods presented because the effects of potentially dilutive items were anti-dilutive.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	The Company is subject to claims and assessment from time to time in the ordinary course of business. The Company accrues a liability for such matters when it is probable that future expenditures will be made and such expenditures can be reasonably estimated. Product Liability Litigation On October 7, 2019, a lawsuit was filed in the Superior Court of the State of California against the Company and Silimed Industria de Implantes Ltda. (the Company’s former contract manufacturer). The lawsuit alleges that the Company’s textured breast implants caused certain of the plaintiffs to develop a condition known as breast implant associated anaplastic large cell lymphoma (“BIA-ALCL”), and that the Company is liable to the plaintiffs based on claims for strict liability (failure to warn), strict liability (defective manufacture), negligence and loss of consortium. On January 21, 2020, the Company filed a demurrer to the plaintiff’s complaint, which demurrer the Court granted in a tentative ruling dated March 9, 2021 with leave to replead. The Plaintiffs filed an amended complaint on April 6, 2021 and the Company filed a demurrer to that complaint on May 6, 2021. On October 25, 2021, the Court issued a ruling granting the Company’s demurrer in-part and denying it in-part, and gave plaintiffs twenty days to file an amendment complaint. A second amended complaint was filed on November 19, 2021. On December 3, 2021 the Company filed a renewed motion for demurrer as to all plaintiffs based on the recent FDA labelling updates on BIA-ALCL warnings. On January 5, 2022 the Company filed a demurrer to the second amended complaint as to plaintiff Craft and otherwise filed an Answer denying the remaining plaintiff's claims and asserting affirmative defenses. The Company's renewed demurrer as to all plaintiffs, and demurrer as to Craft is scheduled for oral argument on September 20, 2022. On August 3, 2022 the Company entered into confidential settlement agreements with the plaintiffs resolving all disputes between them and dismissing the plaintiffs’ claims with prejudice. As a result of these developments, the Company determined a probable loss had been incurred and recorded $ 1.6 million of legal settlement expenses within general and administrative expense in the condensed consolidated statement of operations for the six months ended June 30, 2022. On September 23, 2020, a lawsuit was filed in the Eastern District of Tennessee against the Company. The lawsuit alleges that the Company’s textured breast implants caused certain of the plaintiffs to develop a condition known as breast implant associated anaplastic large cell lymphoma (“BIA-ALCL”), and that the Company is liable to the plaintiffs based on claims for negligence, strict liability (manufacturing defects), strict liability (failure to warn), breach of express and implied warranties, and punitive damages. The Company filed a motion to dismiss the complaint on December 7, 2020. On February 28, 2022 the Court granted the Company’s motion, and dismissed the plaintiff’s complaint with prejudice. On March 28, 2022, the plaintiff filed a motion for reconsideration of the Court’s order. The Company opposed that motion on April 11, 2022.

Accounting Policies [Abstract]
Basis of Presentation	a. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of Sientra, Inc. (“Sientra”, the “Company”, “we”, “our”, or “us”) in this Quarterly Report on Form 10-Q have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, and the rules and regulations of the U.S. Securities and Exchange Commission, or SEC. Accordingly, they do not include certain footnotes and financial presentations normally required under accounting principles generally accepted in the United States of America for complete financial reporting. The interim financial information is unaudited, but reflects all normal adjustments and accruals which are, in the opinion of management, considered necessary to provide a fair presentation for the interim periods presented. The accompanying condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021 filed with the SEC on March 31, 2022, or the Annual Report. The results for the three and six months ended June 30, 2022 are not necessarily indicative of results to be expected for the year ending December 31, 2022, any other interim periods, or any future year or period. As a result of the miraDry Sale discussed in Note 2, the miraDry business met the criteria to be reported as discontinued operations. Therefore, the Company is reporting the historical results of miraDry, including the results of operations, cash flows, and related assets and liabilities, as discontinued operations for all periods presented herein through the date of the Sale. Unless otherwise noted, the accompanying notes to the unaudited condensed consolidated financial statements have all been revised to reflect continuing operations only. Following the Sale the Company has one operating segment in continuing operations named Plastic Surgery, formerly known as Breast Products. b. Liquidity and Going Concern The accompanying unaudited condensed consolidated financial statements of the Company have been prepared assuming the Company will continue as a going concern and in accordance with generally accepted accounting principles in the United States of America. The going concern basis of presentation assumes that the Company will continue in operation one year after the date these financial statements are issued and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Pursuant to the requirements of the Financial Accounting Standards Board’s Accounting Standards Codification (“ASC”) Topic 205-40, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern for one year from the date these condensed consolidated financial statements are issued. This evaluation does not take into consideration the potential mitigating effect of management’s plans that have not been fully implemented or are not within control of the Company as of the date the condensed consolidated financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company’s ability to continue as a going concern. The mitigating effect of management’s plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Since the Company’s inception, it has incurred recurring losses and cash outflows from operations and the Company anticipates that losses will continue in the near term. During the six months ended June 30, 2022, the Company incurred net losses of $ 36.3 million and used $ 31.0 million of cash in operations. As of June 30, 2022, the Company had cash and cash equivalents of $ 25.0 million, with the ability to receive $ 14.0 million on the term loan pursuant to the credit agreement with MidCap Financial Trust. These conditions raise substantial doubt about the Company's ability to continue as a going concern for a period of at least one year from the date of issuance of these unaudited condensed consolidated financial statements. In an effort to alleviate these conditions, management is currently evaluating various funding alternatives to improve liquidity and may seek to raise additional capital from the sale of equity securities and incremental debt financing. As the Company seeks additional sources of financing, there can be no assurance that such financing would be available to the Company on favorable terms or at all. The Company’s ability to obtain additional financing in the debt and equity capital markets is subject to several factors, including market and economic conditions, the Company’s performance and investor sentiment with respect to the Company and its industry. These unaudited condensed financial statements do not include any adjustments relating to the carrying amounts and classification of assets and liabilities that may be necessary should the Company be unable to continue as a going concern.

Recent Accounting Pronouncements	c. Recent Accounting Pronouncements Recently Adopted Accounting Standards In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848)-Facilitation of the Effects of Reference Rate Reform on Financial Reporting . The amendment provides optional expedients and exceptions for contract modifications that replace a reference rate affected by reference rate reform. The amendments are effective for all entities as of March 12, 2020 through December 31, 2022, and entities may elect to apply by Topic as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. The Company adopted the applicable amendments within ASU 2020-04 prospectively in the second quarter of 2022 and there was no material impact on its condensed consolidated financial statements from the adoption. Recently Issued Accounting Standards In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity . The amendment eliminates certain accounting models and simplifies the accounting for convertible instruments and enhances disclosures for convertible instruments and earnings per share. The amendments are effective for public entities excluding smaller reporting companies for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023 including interim periods within those fiscal years and early adoption is permitted. The Company is currently evaluating the impact that adoption of the standard will have on the condensed consolidated financial statements.
Risks and Uncertainties	d. Risks and Uncertainties As an aesthetics company, surgical procedures involving the Company’s breast products are susceptible to local and national government restrictions, such as social distancing, vaccination requirements, “shelter in place” orders and business closures. In addition, some treatment facilities have reduced staffing and postponed certain non-emergency procedures in response to COVID-19 or diverted resources to treat those patients with COVID-19. The Company anticipates that an increase a continuing shortage in staff, especially nurses, at hospitals across the U.S. due to the impact of COVID-19 may also lower number of non-emergency procedures performed. The inability or limited ability to perform such non-emergency procedures and patients electing to postpone elective aesthetics procedures due to the pandemic significantly harmed the Company’s revenues since the second quarter of 2020 and continued to harm the Company’s revenues during the six months ended June 30, 2022. While many states have lifted certain restrictions on non-emergency procedures and procedural volume rates for non-emergency procedures have been recovering, the Company will likely continue to experience future harm to its revenues while existing or new restrictions remain in place. It is not possible to accurately predict the length or severity of the COVID-19 pandemic or the impact on the Company’s business, including the timing for a broad and sustained ability to perform non-emergency procedures involving the Company’s products. The Company continues to monitor and assess new information related to the COVID-19 pandemic, the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets. Further, the spread of COVID-19 has caused the Company to modify workforce practices, and the Company may take further actions determined to be in the best interests of the Company’s employees or as required by governments. The continued spread of COVID-19, or another infectious disease, and other geopolitical conditions, could also result in delays or disruptions in the Company’s supply chain (for example, sourcing of medical-grade silicone) or adversely affect the Company’s manufacturing facilities and personnel. Further, trade and/or national security protection policies may be adjusted as a result of the COVID-19 pandemic, such as actions by governments that limit, restrict or prevent the movement of certain goods into a country and/or region, and current U.S./China trade relations may be further exacerbated by the pandemic. The estimates used for, but not limited to, determining the collectability of accounts receivable, fair value of long-lived assets and goodwill, and sales returns liability required could be impacted by the pandemic. While the full impact and duration of COVID-19 is unknown at this time, the Company has made appropriate estimates based on the facts and circumstances available as of the reporting date. These estimates may change as new events occur and additional information is obtained.
