Brief summary

The purpose of this study is to compare two standard techniques for breast reconstruction-the prepectoral technique and the subpectoral technique. Again, the prepectoral technique involves putting a tissue expander on top of the pectoralis muscle, while the subpectoral technique involves putting a tissue expander under the pectoralis muscle. The standard approach used at MSK is the subpectoral technique. This study will help researchers find out whether the subpectoral approach is better, the same as, or worse than the prepectoral approach. To decide which approach is better, the researchers will look at which technique causes fewer complications after surgery (for example, infection or the need for a second surgery). Researchers are also interested in seeing which approach causes less pain and use of pain medication after surgery.

Interventions

PROCEDUREPrepectoral Prosthetic Breast Reconstruction

The prepectoral approach involves placing the tissue expander on top of the pectoralis muscle.

PROCEDURESubpectoral Prosthetic Breast Reconstruction

The subpectoral approach involves placing the tissue expander under the pectoralis muscle with or without acellular dermal matrix (ADM).

Design outcomes

Primary

MeasureTime frameDescription
major perioperative complications90 days90-day major complications for tissue expanders (i.e., infection, explantation, and reoperation for mastectomy flap necrosis): * Infection: any event requiring restart of antibiotics (oral or intravenous) following completion of initial perioperative antibiotics or an admission to the hospital for cellulitis. * Explantation: need for tissue expander removal for any cause. * Reoperation: skin excision performed in either the clinic or the main operating room for mastectomy skin flap necrosis.

Secondary

MeasureTime frameDescription
minor complications90 daysMinor complication for tissue expanders is defined as: Seroma: clinically significant non-infected fluid collection requiring either needle aspiration or drain replacement
