title: Dermoid cyst of the Eustachian tube.
abstract: A case of congenital dermoid cyst of the Eustachian tube is reported. Only seven similar cases have been found in our review of the literature. The embryology and usual mode of presentation of these cysts are discussed. Finally, a new surgical approach using a combined retro-auricular and protympanic route is presented.
