Myocutaneous sliding flap for reconstruction of divided eyelid nevus.

ABSTRACT

OBJECTIVE: To evaluate the myocutaneous sliding flap for restructuring the eyelid of divided nevus, thus optimizing the aesthetic outcome. DESIGN: A retrospective clinical study. PARTICIPANTS: Clinical data from patients with a small or medium-sized divided nevus of the eyelids between January 2015 and December 2018 in the Shanghai Ninth People's Hospital were reviewed. METHODS: The safety and efficacy of a surgical approach using a myocutaneous sliding flap were evaluated based on postoperative features and complications. RESULTS: This study included 53 patients with an average age was 21.6 years (range, 2-68 years). The lesions involved the inner canthus in 5 patients (9.43%) and the lateral canthus in 14 patients (26.42%). Three (5.66%) patients had undergone primary surgery elsewhere. Overall, the eyelid margins were in good shape postoperatively at an average follow-up of 22.7 months, and there were no obvious eyelid deformities, lagophthalmos, or other unacceptable complications postoperatively. The nevi were benign intradermal (60.38%), junctional (16.98%), and compound types (22.64%) without malignant transformation, as confirmed by pathologic examination. No malignant transformation was observed until the end of the follow-up period. CONCLUSION: A myocutaneous sliding flap can provide an appropriately size pedicle graft and achieve satisfactory cosmetic results for divided eyelid nevus.
