Abstract:

Objective To compare the clinical efficacy of single-hole axillary endoscopic mastectomy and traditional open incision in the treatment of gynecomastia. Method 33 patients with gynecomastia grade Ⅱ ～ Ⅲ (including 15 cases in an experimental group and 18 in a control group)from April 2020 to May 2021 were enrolled in the retrospective study. Among them, 18 cases were unilateral and 15 cases were bilateral. The operation and postoperative recovery of the two groups were compared. Result The median operation time for the axillary single-hole endoscopic surgery group was 88.67 minutes, the median extubation time was 4.40 days, and the median time for hospitalization was 7.67 days. In the traditional surgery group, the median operation time was 58.06 minutes, the median extubation time was 1.94 days, and the hospitalization median time was 4.89 days. There

was no statistical difference between two groups(P ＞ 0.05). In terms of postoperative complications, there was no infection in both groups. There was one postoperative hematoma in the axillary approach single hole endoscopic group and 2 cases of partial nipple necrosis in the traditional surgical group. There was no significant difference in the incidence of postoperative hematoma and partial papillary necrosis between the two groups (P ＞ 0.05). In terms of postoperative satisfaction, 13 patients in the axillary approach single-hole endoscopic group were rated as very satisfied with the postoperative appearance, and 5 patients in the traditional surgery group were very satisfied. There was a statistically significant difference between two groups (P=0.001). Conclusion Single-hole axillary endoscopic mastectomy for gynecomastia can be widely used in clinic, with better cosmetic effect and higher satisfaction.
