Abstract: Objective To observe the efficacy of the shave excision on the benign lid margin nevus without invasion of tarsusor or conjunctiva. Design Retrospective case series. Participants 110 eyes of 106 patients diagnosed as benign lid margin nevus without invasion of tarsusor or conjunctiva between August 2019 and March 2023 in the Beijing Tongren Hospital. Methods The clinical data of the patients were retrospectively described and analyzed. All patients were treated with shave excision, and were followed up for 6 months after operation. Age and gender of the patients, the location, shape, size of the nevus, the duration of the operation, pathological results, the complications and recurrence of the nevus were recorded. Main Outcome Measures The duration of the operation, pathological results, the complications and recurrence of the nevus. Results The average operation time was 4±1 minute (2~11 minutes). After operation, all patients had good appearance, no obvious scar, no bleeding or infection. Complete removal of nevus was achieved in all patients. Pathological examinations revealed 76 intradermal nevus and 5 compound nevus. No recurrence was found during the follow-up period. There was no complication such as eyelid deformities, ectropion, entropion, or baldness postoperatively. Only 2 patients developed trichiasis after operation, and their symptoms relieved after treatment. Conclusion For the benign lid margin nevus that have no invasion of tarsus or conjunctiva, shave excision is a safe, effective and rapid surgical method. (Ophthalmol CHN, 2024, 33: 67-71)
