Abstract

Choanal polyps are unilateral sinonasal lesions that are classified according to their site of origin. The aim of this report is to highlight an unusual form of choanal polyp and to present a thorough literature review. To the best of our knowledge, only 6 cases of a choanal polyp originating in the inferior turbinate have been previously reported in the literature. We describe 2 new cases. One patient was a 14-year-old boy who presented with nasal obstruction, facial headaches, and obstructive sleep apnea; the other patient was a 70-year-old man who presented with right mucopurulent rhinorrhea and right nasal obstruction. In both cases, nasal fibroscopy detected a polyp arising from the right inferior turbinate and extending toward the right choana. Endoscopic sinus surgery was performed in both cases to ensure a complete excision. Cases of choanal polyp arising from the inferior, middle, and superior turbinates and the septum are rare, although some appear to be more common than is generally believed, especially in the pediatric population. We therefore recommend that unusual forms of choanal polyp be included in the differential diagnosis of a unilateral sinonasal mass.
