鼻腔内に認められた過剰歯の2例 Two cases of supernumerary teeth in the nasal cavity
Two cases of supernumerary teeth in the nasal cavity are reported. Several reports have described ectopic teeth in the maxilla, but eruption into the nasal cavity is rare.<BR>Case 1 was a 42-year-old woman with left nasal obstruction. A tooth mass was found in the left nasal cavity and was extracted via the nostril. The mass was a supernumerary tooth. After the operation, the patient's course was good, and the symptoms of nasal obstruction disappeared.<BR>Case 2 was a 8-year-old girl who consulted a local otorhinolaryngology clinic because of aural pain. Intranasal fiberscopic examination disclosed a foreign body in the left side of the nasal cavity. Computed tomography showed that the foreign body was a tooth. Although the patient was scheduled for extraction of the supernumerary tooth, she had to change hospitals for family reasons.
