Correction of Involutional Entropion by Excising Redundant Skin and Pretarsal Orbicularis Muscle without Vertical and Horizontal Tarsal Fixation

PURPOSE: This study evaluated the effect of the excision of redundant skin and pretarsal orbicularis muscle, without vertical or horizontal tarsal fixation, on the correction of involutional entropion. METHODS: This retrospective interventional case series recruited patients with involutional entropion who underwent excision of redundant skin and pretarsal orbicularis muscle, without vertical or horizontal tarsal fixation, from May 2018 to December 2021. Preoperative clinical characteristics and surgical outcomes, including recurrence at 1, 3, and 6 months, were determined by reviewing the medical charts. Surgical treatment included the excision of redundant skin and pretarsal orbicularis muscle, without any tarsal fixation, and simple skin suture. RESULTS: All 52 patients (58 eyelids) attended every follow-up visit and were thus included in the analysis. Among 58 eyelids, 55 (94.8%) had satisfactory results. The recurrence rate was 3.45% (two eyelids) and the overcorrection rate was 1.7% (one eyelid). CONCLUSIONS: Excision of only redundant skin and the pretarsal orbicularis muscle, without capsulopalpebral fascia reattachment or horizontal lid laxity correction, is a simple surgery for correcting involutional entropion.
