Revision Breast Reconstruction with Prepectoral Pocket Conversion of Submuscular Breast Implants

Prepectoral reconstruction using prosthetic devices has demonstrated a notable increase in popularity and confers a number of advantages over subpectoral placement, including minimal animation, no pain secondary to muscle spasm, and less device displacement or malposition. As such, more women with implants in the dual-plane position are seeking a remedy for animation deformities, chronic pain caused by muscle spasm, and implant malposition. The purpose of this study was to review outcomes following the conversion from subpectoral to prepectoral implant placement.

This was a retrospective review of 63 patients who underwent breast implant conversion from the subpectoral plane to the prepectoral plane from 2009 to 2019.

A total of 73 implant pocket conversions from subpectoral to prepectoral were performed on 41 women who met inclusion criteria for this study. The mean time interval from the initial subpectoral operation to the prepectoral conversion was 1608.4 days. The reasons cited for prepectoral conversion was animation deformity (87.8 percent), significant levels of pain related to the implant (34.1 percent), capsular contracture (26.8 percent), or asymmetries and implant displacements (9.8 percent); 7.8 percent of individuals continued to experience their presenting symptom after plane conversion. Rippling and wrinkling were noted in 19.5 percent of individuals and edge visibility was documented in 4.9 percent. Complication rates were low, and no patients experienced necrosis of the mastectomy flap or nipple-areola complex.

The use of prepectoral conversion for revision implant-based breast reconstruction successfully resolves animation deformity. This technique can be reliably and safely performed in a variety of patient demographics.
