Postmastectomy dual-plane submuscular-subcutaneous implant-based reconstruction: a series of 100 consecutive patients.

Abstract

Advances in cancer knowledge and surgical techniques over the last decades have enabled plastic surgeons to use muscle-sparing procedures and more conservative approaches for implant-based reconstructions. In this paper, the authors describe an innovative subpectoral/subcutaneous implant pocket that represents an evolution of the classical submuscular technique and they report on the first consecutive hundred patients undergoing this procedure. Between April 2019 and May 2022, 100 consecutive patients underwent immediate postmastectomy implant-based reconstruction using the subpectoral/subcutaneous space, for a total of 122 procedures. Medical records were retrospectively reviewed and patients were prospectively followed. During plastic consultations, medical photographs were taken and aesthetic outcomes were scored with patients. Mean follow-up was 18months (range 6-46). Implant loss was observed in two patients (2%). Early minor complications were registered in 19 patients. A total of 80 out of 100 patients completed satisfaction survey assessing their postoperative outcomes. Results were considered satisfactory or very satisfactory by the surgeons and patients in more than 90% of cases. The submuscular/subcutaneous pocket can be considered a new tool in the armamentarium of reconstructive procedures, in between submuscular/subfascial procedures and prepectoral ones. It is a one-stage procedure, its a simple and short time surgery, reproducible, its very well accepted by patients. It has specific indications, advantages, and drawbacks, a careful indication and an accurate surgical technique are mandatory to achieve good results.
