Antro-choanal polyp: a 10-year retrospective study in the pediatric population with a review of the literature.
Antro-choanal polyp is generally recognized to represent approximately 4-6% of all nasal polyps; however, it is much more prevalent in the pediatric population. It warrants special consideration in children because its clinical manifestations may be mimicked by other less benign conditions, such as juvenile angiofibroma, meningoencephalocele, and nasopharyngeal malignancies. Fifty patients with surgically treated nasal polyps were reviewed at the Montreal Children's Hospital, between 1976 and 1986. Fourteen (28%) were antro-choanal polyps. Our results are compared with the literature, and special emphasis was given to radiographic manifestations and the differential diagnoses.
