Abstract:
An ectopic tooth in the nasal cavity is a rare phenomenon, especially on the inferior turbinate. In most of the reported cases, no etiological explanation of the intranasal teeth has been suggested or found. In children, intranasal ectopic teeth are usually associated with cleft lip and alveolus. Here, we report a rare case of a pediatric patient with unilateral nasal obstruction due to an intranasal ectopic tooth originating from the inferior turbinate without any facial and dental deformities. This case is unique due to the unusual location of the ectopic tooth and its presentation in a child without facial and dental deformities.
