Outcomes of smooth round implant-based immediate breast reconstruction: Long-term follow-up results

초록

The issue of breast implant-associated anaplastic large cell lymphoma in 2019 has resulted in the discontinuation of textured breast implants and resumption in the use of smooth round implants. However, in the field of breast reconstruction, long-term follow-up data for direct-to-implant reconstruction using smooth round implants is insufficient. This retrospective study aimed to evaluate the long-term outcomes of breast reconstruction using smooth round implants. This study included 185 patients (208 breasts) who underwent smooth round implant-based immediate breast reconstruction between 2007 and 2018. Their demographic information and surgical and oncological data were collected. Early (within 90 days) and late (after 90 days) complications, reoperations, implant maintenance, and the survival rate were analyzed to evaluate the long-term outcomes and identify the related factors. The mean follow-up period was 112.08 months. The most common early complications were skin necrosis (9.13%) and infection (3.85%). The factors influencing the development of early complications were the mastectomy specimen weight (237.14 +/- 114.84 cc and 298.04 +/- 141.53 cc for no complication and any complication, respectively; p = 0.0123) and implant volume (222.79 +/- 77.76 cc and 264.48 +/- 89.03 cc for no complication and any complication, respectively; p = 0.0082). The most common late complication was capsular contracture (13.46%). Approximately 91.35% of the implants were maintained during the follow-up period. The factors affecting the development of early complications and implant maintenance were the mastectomy specimen weight and implant volume. This study provides information on long-term follow-up results useful in cases where only smooth round implants are available, which can then serve as a basis for future related studies.
