Antrochoanal Polyps: Clinical Presentation and the Role of Powered Endoscopic Polypectomy

Abstract

Antrochoanal polyps are a rare clinical entity. In this review of patients treated between January 1996 and September 2002, there were 18 cases of antrochoanal polyps. The mean age of patients was 20 years. Nasal obstruction was the most common symptom (17 cases, 94%), followed by rhinorrhoea (44%), epistaxis (33%), postnasal drip (28%), and snoring (22%). Chronic sinusitis was the most common associated rhinological finding (50%). Various surgical approaches were used: endoscopic polypectomy and middle meatal antrostomy in seven patients (38.9%), powered endoscopic polypectomy and middle meatal antrostomy in seven patients (38.9%), endoscopic polypectomy and inferior meatal antrostomy in three patients (16.7%) and Caldwell-Luc surgery in one patient (5.6%). No complications were noted in patients treated with powered instrumentation, including the three patients in whom combined transcanine approaches were used. We concluded that powered endoscopic polypectomy was safe and effective. It allowed a more complete dissection and may diminish the chance of recurrence.
