Abstract
BACKGROUND: Animation deformity is an undesirable outcome of subpectoral breast reconstruction that results in abnormal breast contraction with activity, breast pain, and increased implant visibility. Surgical correction requires implant removal and conversion of the reconstruction to a prepectoral plane. The authors present their institutional experience with their preferred surgical technique to treat this challenging problem and outline solutions for increased success in these patients. METHODS: A retrospective review was performed of all patients undergoing conversion of their subpectoral breast reconstruction to a prepectoral plane at the authors' institution. Patient demographics and surgical details were analyzed, and postoperative outcomes and morbidity were assessed. The effects of changing operative strategies on enhanced success are also reported. RESULTS: A total of 80 breast conversions were performed over a 2.5-year period. All patients demonstrated resolution of animation deformity at a mean follow-up of 15.2 months. Two reconstructions (2.5 percent) required an unplanned return to the operating room, and 11 reconstructions (13.8 percent) were treated for infection. Preconversion fat grafting and the use of acellular dermal matrix were both associated with a reduced incidence of postoperative asymmetry and capsular contracture (p < 0.05). There were no reconstructive failures associated with conversion to a prepectoral pocket. CONCLUSIONS: Treatment of animation deformity in the reconstructed patient can be safely performed by surgical conversion to a prepectoral plane. The use of acellular dermal matrix, and preconversion fat grafting, in appropriate patients can improve results. The authors promote this operative algorithm for all reconstructive patients experiencing symptomatic animation deformity with subpectoral breast reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
