Oral mucous membrane grafting for unilateral lid margin keratinization following radiotherapy

Le résumé fourni par la source

We describe the outcomes of oral mucous membrane grafting as a surgical technique for unilateral lid margin keratinization following radiotherapy. A 47-year- old woman presented with an 8-month history of a white spot in her right eye. She had a history of adenoid cystic carcinoma of the right spheno-ethmoid sinus, for which she underwent radiotherapy. Slit-lamp evaluation revealed lid margin keratinization of the right upper and lower eyelids and a keratin plaque on the corneal surface. We performed excision of the keratin plaque and lid margin keratinization, followed by oral mucous membrane grafting of the upper and lower eyelid margins. Histopathological evaluation of the excised lid margin revealed keratinized stratified squamous epithelium, consistent with lid margin keratinization. The corneal surface and lid margins showed no recurrent keratin deposition at the final follow-up, 11 months postoperatively.
