纹理植入物和扩张器与乳房植入物相关的大细胞淋巴瘤（BIA-ALCL）的增加风险有关。因此，整形外科医生正在使用平滑扩张器，但许多人认为这会产生不良结果，包括感染、积液和侧向位移。为了比较平滑和纹理扩张器的临床结果，我们对2018年1月至2021年5月的乳房重建患者进行了回顾性研究。符合纳入和排除标准的患者接受了乳房切除术时的组织扩张器置入。主要结局包括术后积液、感染、错位、最终重建时间、植入物取出术和需要胶囊缝合术的情况。共有233位患者接受了回顾，其中167位患者符合纳入和排除标准。比较平滑和纹理扩张器，发现不良结果没有统计学上显著差异。每个乳房的最终重建时间与平滑扩张器相关较低（p = 0.0424）。胸肌下组与进行胶囊缝合术的可能性增加相关（p = 0.004）。胸前组置入与更多的积液（p = 0.0176）和感染（p = 0.0245）相关。人口统计学因素包括年龄较大作为进行胶囊缝合术的保护因素（OR = 0.962，p = 0.038），肥胖增加感染（OR = 5.683， p = 0.0279）和错位（OR = 6.208， p = 0.0222）的风险，放射治疗与错位（OR = 3.408，p = 0.0246）相关。平滑和纹理扩张器之间在不良结果上没有显著差异。与组织扩张器纹理相比，患者的人口统计学和解剖平面置位对感染、积液和需要胶囊缝合术有更大的影响。© 作者（们）2023. 由牛津大学出版社代表美学学会出版。版权所有。如需授权，请发送电子邮件至：journals.permissions@oup.com。

Textured implants and expanders are associated with an increased risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). As a result, plastic surgeons are utilizing smooth expanders, but many perceive these produce undesirable outcomes including infection, seroma, and lateral displacement.To compare clinical outcomes of smooth and textured expanders.We retrospectively reviewed breast reconstruction patients from January 2018 to May 2021. Included patients underwent placement of tissue expanders at the time of mastectomy. Primary outcomes included postoperative seroma, infection, malposition, days to final reconstruction, explantation, and need for capsulorrhaphy.233 patients were reviewed, and 167 patients met both inclusion and exclusion criteria. There was no statistically significant difference in poor outcomes comparing smooth and textured expanders. Days to final reconstruction was lower with smooth expanders per breast (p = 0.0424). The subpectoral group was associated with an increased likelihood of undergoing capsulorrhaphy (p = 0.004). Prepectoral placement was associated with more seromas (p = 0.0176) and infections (p = 0.0245). Demographic factors included older age as a protective factor for undergoing capsulorrhaphy (OR = 0.962, p = 0.038), obesity increased the risk of infection (OR = 5.683, p = 0.0279) and malposition (OR = 6.208, p = 0.0222) and radiation was associated with malposition (OR = 3.408, p = 0.0246).There was no significant difference in poor outcomes comparing smooth and textured expanders. Patient demographics and anatomical plane placement had greater effects on infection, seroma and need for capsulorrhaphy compared to tissue expander texturing.© The Author(s) 2023.
