Abstract: 【Abstract】 Objective To investigate the application of horizontal closure of longitudinal incisions in repairing pentagonal full-thickness defects of the lower eyelid margin. Methods A retrospective analysis was performed on clinical data collected from 26 patients with melanocytic nevi at the lower eyelid margin in Department of Dermatology, The Third People’s Hospital of Hangzhou from July 2016 to June 2019. Among the 26 patients, 10 were males, and 16 were females. After lesion resection, all the pentagonal full-thickness defects at the lower eyelid margin were repaired via horizontal closure oft longitudinal incisions. Results All the pentagonal defects of the 26 cases were successfully repaired. The longitudinal incisions perpendicular to the eyelid were successfully converted into transverse incisions parallel to the eyelid margin and near the eyelash, and all incisions healed primarily. After surgery, mild congestion of the lower eyelid occurred in 3 patients, and temporary blurred vision in 1. During 1 - 2 years of postoperative follow-up, 26 patients all achieved symmetrical appearance of the skin and soft tissues around the eyes, without obvious postoperative scars or lower eyelid ectropion. Conclusions Horizontal closure of longitudinal incisions can be used to repair the pentagonal full-thickness defects of the lower eyelid margin, because it can convert the incision closure line perpendicular to the lower eyelid margin into a horizontal transverse incision closure line parallel to the lower eyelid margin, so that the incisions and scars of the lower eyelid can be hided with a satisfactory cosmetic effect.
