Clinical and Histological Differences Between Choanal Polyps in Children and Adults: A 15-Year Retrospective Study.

Choanal polyps (CPs) are benign, inflammatory, solitary lesions extending toward the junction between the nasal cavity/paranasal sinus and the nasopharynx through the choana. This study aimed to evaluate the clinical and histological characteristics of CPs in children compared to adult patients. Characteristics of patients (demography, main complaints, side, localization, surgical approach, histological characteristics, accompanying chronic rhinosinusitis [CRS], association with allergic rhinitis [AR] and aspirin sensitivity, postoperative follow-up period, recurrence rates) were retrospectively reviewed.
