Retrospective analysis between complication and nipple areola complex preservation in direct-to-implant breast reconstruction.

[BACKGROUND] Since the introduction of skin-sparing mastectomy (SSM), more breast surgeons have been preserving the areola and often nipple areolar complex (NAC) entirely. For better outcomes, more studies are necessary to analyze whether preserving the areola or NAC is unfavorable in breast reconstruction. The aim of this study was to assess the potential risk of areola or NAC preservation in direct-to-implant (DTI) breast reconstruction after SSM.

[METHODS] We retrospectively reviewed the medical records of patients who underwent immediate breast reconstruction from May 2011 to July 2017. Immediate breast reconstruction was performed with DTI procedure in all cases. In total, 213 breasts met the inclusion criteria and were divided into 3 groups: nipple-sparing mastectomy (NSM), aerola-sparing mastectomy (ASM) which only nipple is excised, and skin-sparing mastectomy (SSM) which whole NAC was excised. Complications including infection, capsular contracture, skin necrosis and explantation were measured.

[RESULTS] The mean patient age was 45.3 years, with a range of 27-62 years; the mean follow-up was 3.08 years. NSM, ASM and SSM groups consisted of 121, 30 and 62 breasts, respectively. The Infection rates were statistically lower in SSM group (4.8%) compared with NSM group (15.7%) (P=0.033) but not statistically different from ASM group (13.3%) (P=0.210). SSM group showed significantly lower rate of overall complication compared with both NSM and ASM groups (P=0.005, 0.025 respectively).

[CONCLUSIONS] Our research suggests that preservation of the NAC increases the rate of infection and skin necrosis in DTI breast reconstruction.
