Abstract
Two-stage implant-based breast reconstruction remains the most commonly used technique for rebuilding a breast. Subpectoral implant placement minimizes complications, such as capsular contracture, implant visibility, malposition, and extrusion. Nevertheless, it is associated with high animation deformity (AD). Prepectoral reconstruction eliminates AD but is subject to a higher risk of implant extrusion and visibility. In this prospective, single-center study we present a new technique aimed to create a new hybrid pocket in which the upper portion of the implant is placed subcutaneously, whereas its inferior pole is still covered by a pectoralis muscle sling reducing implant lower pole visibility and palpability. In each case, the prosthesis was removed and a new hybrid pocket was created by splitting the muscle into two portions, separating its cranial part from the overlying subcutaneous tissue and anchoring it back to the chest wall. The caudal muscle sling was left adherent to the subcutaneous tissue of the central part of the breast. Patient outcomes were evaluated with a BREAST-Q questionnaire preoperatively and 1 year after surgery. Forty-eight patients with severe postoperative breast animation were enrolled (8 bilateral and 40 unilateral). No major complications occurred. After a 1-year follow-up, the aesthetic and functional satisfaction rate was high and a good implant coverage was achieved. No residual AD of the breast was observed. Changing the implant placement from the subpectoral to a partially subcutaneous plane, both severe AD and implant extrusion can be avoided, expanding the indications for safe prosthetic breast reconstruction. Level of evidence IV.
