乳房植入相关的间变性大细胞淋巴瘤 (BIA-ALCL) 是一种非霍奇金淋巴瘤，于 2011 年首次与乳房植入物相关。BIA-ALCL 与纹理装置之间的相关性导致光滑装置的使用增加。然而，围绕平滑和纹理装置的许多数据专门研究乳房植入物，而不是组织扩张器 (TE)。我们进行了系统回顾和荟萃分析，以比较平滑组织扩张器 (STE) 和纹理组织扩张器 (TTE) 的手术结果）。在 PubMed 上进行检索，包括 2016 年至 2023 年的文章（n = 419）。比较 TTE 和 STE 以及报告的并发症的研究也包括在内。采用随机效应模型进行荟萃分析。共有 5 篇文章符合纳入标准，代表 STE 队列中的 1,709 名患者和 TTE 队列中的 1,716 名患者。 STE 组织扩张的平均持续时间为 221.25 天，而 TTE 组织扩张的平均时间为 220.43 天。我们的荟萃分析发现，除了移植风险外，所有手术结果没有差异。与 TTE 使用相比，STE 使用与外植几率增加超过 50% [OR = 1.53； 95% CI = 1.15至2.02； P = 0.003]。总体而言，STE 和 TTE 具有相似的并发症情况。然而，STE 的外植几率高出 1.5 倍。 BIA-ALCL 的发病率较低，仅报道过一种 BIA-ALCL 伴有 TTE。这表明 TTE 是安全的，并且可以降低需要外植的早期并发症的风险。需要进一步研究来进一步明确组织扩张器和 BIA-ALCL 之间的关系。© 作者 2023。由牛津大学出版社代表美学协会出版。版权所有。如需权限，请发送电子邮件至：journals.permissions@oup.com。

Breast-Implant Associated-Anaplastic Large Cell Lymphoma (BIA-ALCL) is a type of non-Hodgkin lymphoma first linked with breast implants in 2011. The correlation between BIA-ALCL and textured devices has led to increased use of smooth devices. However, much of the data surrounding smooth and textured devices investigates breast implants specifically and not tissue expanders (TEs).We performed a systematic review and a meta-analysis to compare surgical outcomes for smooth tissue expanders (STEs) and textured tissue expanders (TTEs).A search was performed on PubMed, including articles from 2016 to 2023 (n = 419). Studies comparing TTEs and STEs and reported complications were included. A random-effects model was utilized for meta-analysis.A total of 5 articles met inclusion criteria, representing 1,709 patients in the STE cohort and 1,716 patients in the TTE cohort. The mean duration of tissue expansion with STEs was 221.25 days, while TTEs had a mean time of tissue expansion of 220.43 days.Our meta-analysis found no differences in all surgical outcomes besides explantation risk. STE use was associated with increasing odds of explantation by over 50% compared to TTE use [OR = 1.53; 95% CI = 1.15 to 2.02; P = 0.003].Overall, STE and TTE had similar complication profiles. However, STE had 1.5 times higher odds of explantation. The incidence of BIA-ALCL is low, and only a single BIA-ALCL has been reported with TTEs. This indicates that TTEs are safe and may lower the risk of early complications requiring explantation. Further studies are warranted to further define the relationship between tissue expanders and BIA-ALCL.© The Author(s) 2023. Published by Oxford University Press on behalf of The Aesthetic Society.
