Choanal adenoid syndrome--a preliminary report.

A series of 19 patients with long-lasting nasal stenosis despite repeated treatment attempts, including, in many cases, repeated adenoidectomy, was found to have ectopic adenoid tissue inside the choanae. The choanal adenoid tissue could not be removed by curettage, only transnasally using forceps. The treatment was successful in all 19 patients. It is estimated that in at least 2% of the patients with long-lasting nasal stenosis, attention should be focused on the bottleneck of the nasopharyngeal airway represented by the choanae, primarily by fibre optic endoscopic examination.
