Purpose: To report an outcome of a patient with complete ankyloblepharon successfully managed with simple oral mucosal epithelial transplantation (SOMET)., Methods: A 55-year-old woman presented with complete adhesion of both lids to the ocular surface as a complication from Stevens-Johnson syndrome. We performed 2-staged reconstructive surgeries: the first stage was to perform ankyloblepharon lysis and surface reconstruction with a mucosal graft on the palpebral area and an amniotic membrane on the bulbar area, and the second stage was to reconstruct the bulbar area with a transplantation of small pieces of oral mucosa (SOMET technique). Postoperatively, the patient was evaluated for ocular surface stability, recurrent symblepharon, in vivo confocal microscopy, and impression cytology with immunofluorescence staining., Results: Complete epithelialization of cornea-like epithelium was observed within 6 weeks after SOMET was performed. The ocular surface was stable over 1 year. Both fornices remained deep. In vivo confocal microscopy showed cornea-like epithelium mixed with conjunctival epithelium, as confirmed with immunofluorescence staining, which revealed cytokeratin 3, cytokeratin 7, and cytokeratin 12 positivity., Conclusions: SOMET is a simple modified technique using minimal oral mucosal tissue to regenerate epithelialization for complicated ocular surface reconstruction such as a complete ankyloblepharon repair. Although there was evidence of conjunctival invasion, stable ocular surface and deep fornices can be achieved for further visual rehabilitative procedure., Competing Interests: The authors have no funding or conflicts of interest to disclose., (Copyright © 2020 Wolters Kluwer Health, Inc.
