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.
鼻窦道内牙齿的异位萌出以及移位的牙碎片从上颌窦迁移至鼻腔是两种罕见的现象。本文报告了三例病例：一例鼻中隔内无症状的异位牙、一例引起鼻窦炎反复发作的上颌窦异位牙以及一例与曲霉菌性鼻窦炎相关的牙根经上颌窦到达鼻腔的病例。文中还讨论了鼻窦牙的病因、诊断、并发症及治疗。
