Abstract

This study was conducted to review the clinical features of antrochoanal polyp and to evaluate the effectiveness of transnasal endoscopic sinus surgery as a primary surgical method in treating antrochoanal polyp. We reviewed the profiles, which included clinical symptoms, past surgical history, surgical techniques and operative findings, of 57 patients (62 cases) treated for antrochoanal polyp with transnasal endoscopic sinus surgery during the past four years. Out of this subject pool, 45 patients (50 cases) underwent follow-up examinations and were analyzed. The follow-up periods ranged from 18 to 63 months and averaged 33 months. About half of the cases involved pediatric-to-young-adult patients (under 20 years) and five cases were bilateral. The most frequent site of origin was the natural ostium of the maxillary sinus, followed by the posteromedial wall and the posterolateral wall. Recurrences after endoscopic sinus surgery were observed in five cases, which were subsequently treated with revision endoscopic sinus surgery. In these cases of recurrence, there was no evidence of recurrence during a mean follow-up period of 30 months. These results suggest that transnasal endoscopic sinus surgery may be appropriate for the primary treatment of antrochoanal polyp and useful in the treatment of recurrent cases, especially those involving children.
