Background: Difficulties that arise with subpectoral breast implant placement include the following: malpositioning of the implant; improper superior contouring; and unnatural movement with chest muscle contraction. Correction of these deformities is easily achieved by removal of the subpectoral implant, resuspension of the pectoralis major muscle to the chest wall, and reaugmentation with a new implant in the subglandular plane. This study defines a correction modality for the adverse results of subpectoral implant placement in augmentation mammaplasty.

Methods: Pectoralis major resuspension was performed in 36 patients undergoing revision aesthetic breast surgery from 1995 to 2006. All patients had previously placed subpectoral breast implants performed elsewhere with unwanted movement, malposition, and/or capsular contracture. All patients underwent explantation of the breast implant, modified capsulectomy, pectoralis major resuspension, and reaugmentation of the breast in the subglandular position. In cases of symmastia, medial capsulodesis and sternal bolster sutures were used. Patients were evaluated for resolution of symptoms, satisfaction, and complications.

Results: Malposition (62 percent), capsular contracture (53 percent), and symmastia (10 percent) were the most common indications for revision, but 100 percent of patients were dissatisfied with abnormal breast movement. The average follow-up time was 20 months. The silicone implants were commonly used, with an average volume change decrease of 27 cc. Unwanted implant movement was eliminated completely (100 percent), symmastia was corrected (100 percent), and capsular contraction was significantly decreased in each respective group. Patient satisfaction with this procedure was high, with a low complication rate.

Conclusions: Pectoralis major resuspension can be performed successfully in aesthetic breast surgery. It can be applied safely to correct problems of unwanted implant movement, symmastia implant malposition, and capsular contraction. The use of silicone gel implants in a novel tissue plane may be beneficial in this diverse, reoperative patient population.
