Sphenochoanal polyp is a rare entity which originates in the sphenoid sinus and extends into the choana via the ostium. It may be confused with an antrochoanal polyp on anterior rhinoscopy. Computerized tomography and nasal endoscopy have contributed to an increase of accuracy in the diagnosis of these lesions. Simple avulsion of the choanal polyp is associated with a high risk of recurrence. Recurrences can be prevented by total excision of the polyp inside the sinus under the endoscopic guidance. We present a case of sphenochoanal polyp in a 5 year old child that was removed by endonasal endoscopic approach. (J Clinical Otolaryngol 2008;19:214-217)
