Abstract: Objective: To analyze the curative effect of skin flap repair combined with catheter ligation in the treatment of distal finger or toe myxoid cysts. Methods: The access of patients with distal interphalangeal myxoid cysts treated with cyst excision, distal ligation of cyst catheter and skin flap repair from June 2023 to June 2024 were analyzed retrospectively. The range of motion, appearance, function, and pain of the fingers or toes were evaluated after the operation and all the patients were followed up for half a year. Results: A total of 28 patients were included, all the flaps survived well after operation. The range of motion of the fingers or toes was good after operation. The excellent and good rate was significantly improved compared with that before operation (85.7% before operation, 96.4% after operation, P＜0.05). Patients' satisfaction with the appearance of fingers or toes after operation was improved, and the difference was statistically significant (P＜0.001). The pain in the original cyst site was significantly improved compared with that before operation (4.15±0.75 before operation, 1.15±0.37 after operation, P＜0.0001). There was no recurrence and obvious scar hyperplasia during the 6-month follow-up period. Conclusion: Skin flap combined with catheter ligation to treat digital myxoid cyst can preserve joint function, reduce trauma and reduce postoperative recurrence rate.
