Summary

The purpose of this study is to prospectively compare and analyze the incidence of complications in patients undergoing postmastectomy radiation therapy after breast reconstruction with subpectoral and prepectoral placement of implant. Investigators hypothesized that immediate acellular dermal matrix-assisted implant-based breast reconstruction with prepectoral implant placement would result in lower risk of capsular contracture after postmastectomy radiation therapy(PMRT) compared with acellular dermal matrix(ADM)-assisted implant-based breast reconstruction with subpectoral implant placement.

PROCEDURE

Arm I (Prepectoral), Arm II (Subpectoral)

Arm I (Prepectoral)De-epithelialized skin flaps are made from the inferior pole of breast skin and soft tissue. The implant pocket is shaped by fixing a sufficiently large amount of ADM to the medial surface of the mastectomy pocket, the upper edge of the pectoralis major muscle and the de-epithelial skin flap. The implant is located in the prepectoral mastectomy pocket and the ADM anchored to the chest wall, serratus fascia, and de-epithelial skin flaps. The pectoralis major muscle is located in the anatomical location behind the ADM. Arm II (Subpectoral)The pectoralis major muscle is dissected from the thorax to create sufficient space for the implant to be placed behind the pectoralis major muscle. Implant pockets are made by suturing the lower part of the elevated pectoralis major muscle to the top of the de-epithelial skin flap and the ADM patch to the skin flap, the pectoralis major muscle, and the lateral thoracic fascia.
