An alternative surgical approach for sublingual dermoid cysts: a case report.

A 52-year-old woman presented with a painless swelling in the floor of the mouth. She stated that it had existed there for 40 years and had undergone a gradual enlargement within the past year. Examination showed a mass, 5x4 cm in size. An aspiration from the lesion revealed a cyst. The lesion was removed by a U-shaped superior based flap. Histopathological examination showed stratified squamous epithelium lining the cystic lumen. This technique can be an alternative approach in such lesions because it protects the oral mucosa by providing good exposure, and prevents injury to the lingual nerve and submandibular duct.
