구강내 접근법을 통한 구강저 유표피낭종의 3 치험례

Epidermoid cyst of the mouth floor represents an unusual clinical entity. It may be caused by ectopic invagination of ectodermal tissue. Only 6.9% of dermoid cysts developed in head and neck region and it accounts for less than a quarter of those dermoids occurring within the oral cavity. Most lesions are seen in young adults.

There are two way of approach during removal of epidermoid cyst intraoral or external respectively. Each approach has some merits and demerits. The authors have recently exprienced three cases of huge epidermoid cyst of the mouth floor. All cysts were removed intraorally. And intraoral approach thought to be most appropriate method and has some advantage of no external scar in treating mouth floor epidermoid cyst.
