Nanotextured breast implants were hailed as an innovation that may address capsular contracture and breast implant-associated anaplastic large cell lymphoma and may provide the sweet spot between smooth and conventional textured implants.
This study aimed to evaluate the introduction of nanotextured implants alongside conventional textured implants and to compare early complications.
Patients who underwent breast augmentation from the introduction of nanotextured implants in the author's practice with at least 1 year of follow-up were included. They were divided into nanotextured and conventional textured implant groups and then into 3 chronological subgroups. Patient characteristics, implant specifications, operative factors, and complication rates were compared.
A total 415 cases with a mean follow-up of 26.9 months were identified, of which 38.8% utilized nanotextured implants and 61.2% conventional textured implants. Utilization of nanotextured implants increased from 26.9% in period 1 to 54.5% in period 3. Complication rates for the conventional textured group were 0.8% at 1 year and 3.5% on overall follow-up, with mostly capsular contractures; for the nanotextured group, complication rates were 6.8% and 8.7%, respectively, and "bottoming out" was most common. When analyzed across chronological subgroups, complication rates decreased for nanotextured implants by period 3.
A learning curve and associated complications are expected for early adopters of new implants. In our series, nanotextured implants were associated with higher complication rates at 1 year and on overall follow-up. Modifications in patient selection, intraoperative techniques, and postoperative care reduced complications in the later period.
纳米纹理乳房植入物被誉为一项创新,可能解决包膜挛缩和乳房植入物相关间变性大细胞淋巴瘤的问题,并可能在光滑和传统纹理植入物之间提供一个理想的选择。
本研究旨在评估纳米纹理植入物与传统纹理植入物同时引入,并比较早期并发症。
纳入作者所在机构自引入纳米纹理植入物以来至少随访 1 年的乳房隆乳患者。将患者分为纳米纹理和传统纹理植入物组,然后再分为 3 个时间顺序亚组。比较患者特征、植入物规格、手术因素和并发症发生率。
共确定了 415 例平均随访 26.9 个月的病例,其中 38.8%使用纳米纹理植入物,61.2%使用传统纹理植入物。纳米纹理植入物的使用率从第 1 期的 26.9%增加到第 3 期的 54.5%。传统纹理组的并发症发生率在第 1 年为 0.8%,总随访期为 3.5%,主要为包膜挛缩;纳米纹理组的并发症发生率分别为 6.8%和 8.7%,最常见的是“底部凹陷”。按时间顺序亚组分析,纳米纹理植入物的并发症发生率在第 3 期降低。
对于新植入物的早期采用者,预计会有学习曲线和相关并发症。在我们的系列中,纳米纹理植入物在第 1 年和总随访期的并发症发生率更高。在患者选择、术中技术和术后护理方面的改进,降低了后期的并发症发生率。
