안면 비대칭을 동반한 선종양치성종 1예

Adenomatoid odontogenic tumor is an uncommon benign odontogenic tumor, most often associated with an unerupted maxillary canine. The tumor is usually asymptomatic due to its slow growth. However, since facial deformities can result from the tumor, early detection and treatment are necessary. A 9-year-old girl visited our department due to an incidental finding of a maxillary mass during a brain magnetic resonance imaging examination. The right maxilla of the patient was protruded and facial asymmetry had developed. The mass was excised via the canine fossa approach and diagnosed as an adenomatoid odontogenic tumor. We report this rare case along with a literature review. (J Clinical Otolaryngol 2017;28:256-260)
