Epidermoid cyst of the floor of the mouth

Abstract

The characteristics and incidence of dermoid cysts of the floor of the mouth are reviewed. The epidermoid cyst in the sublingual (genioglossal) position is unique because of its size and the advanced age of presentation. The use of preoperative lateral xerography was beneficial in determining the extent of the lesion and in visualizing the partial obstruction of the upper airway. An intraoral surgical technique was used to treat the cyst.
