Dermoid cyst in the floor of the mouth. Review of the literature and case reports.
Dermoid cyst, frequently used to describe three closely related histologic cysts, the dermoid, epidermoid, and teratoma, is commonly considered a rare finding in the floor of the mouth. This review, which identifies 195 case reports of dermoid cysts in the floor of the mouth, has unveiled some findings that do not support conclusions expressed in previous articles. Examination of the literature includes muscle influence on clinical presentation and surgical approaches, locations, age distribution, histologic distribution, infection rate, incidence of multiple cysts, fibrous attachments, airway problems, anesthesia administration, surgical difficulties, and diagnostic aids. Brief suggestions in treatment are made in light of the clinical, radiographic, and historic findings. Three clinical cases are also included.
