The Lateral Tarsal Strip for Paralytic Ectropion in Patients with Leprosy

Background In patients with leprosy, paralysis of the facial nerve results in the lower eyelid ectropion and lagophthalmos as a sequela even when the leprosy is cured. Paralytic ectropion causes many functional and cosmetic eye problems, leading to blindness if left untreated. Objective The purpose of this retrospective study is to evaluate the efficacy of surgical correction of paralytic ectropion, the lateral tarsal strip, in patients with leprosy. Methods Between 2010 and 2015, 40 Korean patients (44 eyelids) with paralytic ectropion who had visited Korean Hansen Welfare Association Hospital were treated with the lateral tarsal strip. Four-point patients' global assessment scale, local complications, and recurrence were assessed at the end of follow-up period. The average follow-up period was 12 months. Results In the 44 eyelids, recurrence was observed in 5 cases (5/44, 11.4%). There were no serious postoperative complications except mild size discrepancy of both eyes. Most patients were satisfied with the results and mean satisfaction scale was 2.6/3. Conclusion The lateral tarsal strip is a simple, safe, and effective treatment method for the dermatologic surgeon to correct paralytic ectropion of mild to moderate degree in patients with leprosy.
