Sensitivity of the Nipple-Areola Complex in Reduction Mammaplasty Following Periareolar Dermis Section.

Abstract

Preservation of the periareolar dermis, after de-epithelization in reduction mammaplasty, may result in reduced nipple-areola complex (NAC) mobility. Consequently, distortion in shape and difficulty correcting the areola position can occur. The aim of this study was to evaluate NAC viability and sensitivity resulting from periareolar dermis section after de-epithelization in patients who underwent reduction mammaplasty surgery. This study was a randomized, controlled double-blind clinical trial. A total of 41 patients (82 breasts) were randomly allocated into 2 groups and underwent reduction mammaplasty-involving the superior pedicle-with a final inverted T-shaped scar. A sectioning of the periareolar dermis was performed on the breasts in the experimental group. Semmes-Weinstein monofilaments were used to evaluate NAC sensitivity at the preoperative evaluation, and 3, 6, and 52 weeks after surgery. No cases of partial or total NAC necrosis were noted in either group. The comparison between the groups did not show significant differences regarding NAC sensitivity. However, a statistically significant difference was noted when sensitivity levels at the preoperative evaluation and 3 weeks after surgery were compared in the experimental group. A significant difference was noted when the scores of the sensitivity 3 weeks after surgery were compared between the control and the experiment groups. Nevertheless, after 1 year, no statistical differences were observed in the experimental group or between both groups. The sectioning of the periareolar dermis does not affect the viability or the pressure sensitivity of the NAC.
