RESUMEN
The aim of this prospective case series study is to assess the outcome of endoscopic sinus surgery on antrochoanal polyps in 17 patients over one year period. Seventeen patients with antrochoanal polyps were treated in the department of otorhinolaryngology in al-Jamhoree Mosul teaching Hospital from March 2006 up to February 2007. They had endoscopic transnasal surgery as the method of treatment, and all patients were followed one year postoperatively. Only one pediatric patient had recurrent polyp after 6 months and was subjected to another surgery which was complicated by temporary epiphora. Another patient had adhesions, otherwise all patients had improvement of symptoms, and frequent follow ups over one year showed no recurrence. No major complications were reported in any patient. The endoscopic transnasal surgery of antrochoanal polyp is a minimally invasive technique which is both effective and safe
