title: A case report of supernumerary tooth and review of literature.
abstract: A boy visited an ear-nose and throat clinic for serous rhinorrhea and a tumor-like mass in the nasal cavity. X-ray and computered tomographies showed a bone-like mass with a slightly radiolucent center which seemed to stem from the nasal septum. A supernumerary tooth in the nasal cavity was extirpated under local anesthesia. In some reports, complications of supernumerary tooth were severe and involved areas other than the nose (cleft lip and/or palate, bilateral aniridia and ectopia lentis, familial adenomatous polyposis coli, ventricular septal defect or patent ductus arteriosus). A case had a risk of inducing severe intracranial complication. Therefore we must not overlook a supernumerary tooth.
