Immediate Implant-Based Breast Reconstruction following Total Skin-Sparing Mastectomy in Women with a History of Augmentation' Mammaplasty: Assessing the Safety Profile

摘要

Background: Preservation of the nipple-areolar complex with total skin-sparing mastectomy is becoming a popular mastectomy technique. As experience increases, the patient inclusion criteria for total skin sparing mastectomy expand. The authors assessed outcomes of total skin-sparing mastectomy and immediate prosthetic reconstruction in women with a prior history of augmentation mammaplasty.Methods: Between 2005 and 2012, all women with a history of augmentation mammapiasty and implants in place, undergoing total skin-sparing mastectomy and immediate prosthetic reconstruction, were prospectively tracked. Patient demographics, expander coverage type, adjuvant treatment, and incidence of complications were analyzed. Outcomes in these patients were compared with those of patients undergoing the same operation, without prior augmentation history.Results: Thirty-four women with prior augmentation underwent total skin-sparing mastectomy and immediate tissue expander placement on 5.1 breasts. Comparison to the nonaugmenlalion group showed similar rates of superficial nipple necrosis (0 percent, p= 0.324), complete nipple necrosis (0 percent, p= 0.324), and skin flap necrosis (4 percent, p = 1.0). The prior augmentation group did have a higher rate of implant loss (10 percent, p = 0.515), with all but one of these occurring in irradiated patients.Conclusions: Total skin-sparing mastectomy and immediate prosthetic reconstruction is a safe technique in women with a history of augmentation mammaplasty. The preferred reconstructive technique is immediate submus-cular tissue expander placement. In the setting of no radiation history, this operation carries a safety profile similar to that of patients without a history of prior augmentation, and can be offered safely.
