Inferolateral Pectoralis Sling Technique for Augmentation Mastopexy.

[BACKGROUND] Augmentation mastopexy remains a challenging procedure. The goal is to achieve correction of breast ptosis whilst adding implant volume, and avoid complications of premature waterfall deformity, bottoming out and further revision surgery, particularly when using smooth implants. We aim to describe and evaluate a technique to reduce implant malposition in augmentation mastopexy.

[METHODS] This is a technical description and retrospective review of a single surgeons' cases from 2019 to 2022 of all patients who underwent 1 stage subpectoral breast augmentation mastopexy with the inferolateral pectoralis sling.

[RESULTS] Over the four year period, 284 patients (568 breasts) underwent augmentation mastopexy with the inferior pectoralis sling. Mean implant size was 360.7cc (range 180-625cc). There were no early complications and 6 (2.1%) patients had late minor complications, with five (1.8%) undergoing revision mastopexy with implant repositioning and 1 (0.4%) undergoing areola scar revision. 20 patients (7%) underwent an implant upsize procedure with the average volume increase being 218.5cc and the average time to upsize 13.6 months (range 6-36 months) CONCLUSIONS: Use of the inferolateral pectoralis muscle sling allows successful one stage augmentation mastopexy with low complication and revision rates.
