鼻腔内に逆生した過剰歯例

Eruption of a tooth into the nasal cavity is a rare clinical entity. We report the case of a 38-year-old man patient with cacosmia and nasal obstruction. A white mass was visually detected on examination as being an inverted tooth in the right nasal cavity. The tooth was diagnosed as a supernumerary tooth by a dentist. We extracted the tooth easily from the nasal cavity with the patient under general anesthesia. After the operation, the patient’s course went well and the symptoms of cacosmia and nasal obstruction have disappeared.
