Topographic Analysis of the Nipple-Areolar Complex Sensation in Superomedial Pedicle Breast Reduction

Background Surgeons meticulously perform breast reductions, while ensuring vascular integrity of the pedicle and Nipple-Areolar complex (NAC) to prevent any complication. It is crucial to remember that loss of sensation is also substantial complication, mainly due to unique characteristic features of the NAC. This study aimed to compare early and long-term sensory results by performing topographic analysis of NAC sensation after superomedial pedicle breast reduction. Methods A prospective study was conducted by including nonrandomized female patients who underwent breast reduction surgery with wise pattern excision superomedial pedicle technique between January 2019 and June 2022. Semmes-Weinstein Monofilament (SWM) test performed at preoperatively, 3-6 months and 15-18 months postoperatively. NAC complex was divided into four equal quadrants and nipple: superomedial (SM), inferomedial (IM), inferolateral (IL), superolateral (SL) and Nipple (N). Touch-Test((R)) Sensory Evaluator Chart was used to evaluate sensory results. Results None of the patients had any loss of sensation during preoperative SWM test. In postoperative 3-6 months, statistically significant differences were observed between N and SL (p=0.002), SL and IM (p<0.05), SM and IM (p<0.05). In postoperative 15-18 months, there was no difference between the quadrants and nipple (p=0.07). In early and long-term comparisons of the same quadrants, IL less pronounced than other quadrant comparisons (p=0.034). A statistical difference was observed in overall NAC score (p<0.05). Conclusions It would be beneficial to inform patients overall NAC sensation in the postoperative may not be as good as preoperative, there might be variations in NAC sensation across different quadrants in early period.
