Abstract：
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® 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.

摘要：
背景：外科医生精心做乳房缩小术，同时确保椎弓根和乳头-乳晕复合体（NAC）的血管完整性，以防止任何并发症。重要的是要记住，感觉的丧失也是实质性的并发症，主要是由于NAC的独特特征。本研究旨在通过对超内侧椎弓根乳房缩小后的NAC感觉进行地形图分析，比较早期和长期的感觉结果。
方法：在2019年1月至2022年6月期间，进行了一项前瞻性研究，纳入了非随机女性患者，这些患者接受了明智式切除超内侧椎弓根技术的乳房缩小手术。术前进行Semmes-Weinstein单丝（SWM）测试，术后3-6个月和15-18个月。NAC复合物分为四个相等的象限和乳头：超内侧（SM），下颌(IM)，下外侧（IL），上外侧（SL）和乳头（N）。使用触摸测试®感官评估图表来评估感官结果。
结果：在术前SWM测试中没有患者有任何感觉丧失。术后3-6个月,在N和SL之间观察到统计学上的显着差异（p=0.002），SL和IM(p<0.05)，SM和IM(p<0.05)。术后15-18个月,象限和乳头之间没有差异（p=0.07）。在同一象限的早期和长期比较中，IL不如其他象限比较明显(p=0.034)。在总体NAC评分中观察到统计学差异(p<0.05)。
结论：告知患者术后的总体NAC感觉可能不如术前好，在早期，不同象限的NAC感觉可能存在差异。
