Antral-choanal polyps.
The series involves 38 patients who had antral-choanal polyps removed at the Mayo Clinic during the 10 year period between 1965 and 1974. In contrast to common nasal polyps, antral-choanal polyps often are solitary and unilateral and usually are not associated with an allergic diathesis. These polyps recur frequently if they are simply avulsed; permanent ablation of the polyps requires thorough curettage of the antrum.
