title: Sinonasal teeth.
abstract: Ectopic eruption of the teeth in the sinonasal tract and the migration of a displaced dental fragment from the maxillary sinus to the nose are two rare phenomena. This paper reports three cases: an asymptomatic ectopic tooth within the nasal septum, an ectopic maxillary sinus tooth causing repeated attacks of sinusitis, and a dental root that reached the nose through the maxillary antrum associated with Aspergillus sinusitis. The etiology, diagnosis, complications, and treatment of simonasal teeth are discussed.
