Abstract

Sphenochoanal polyp is a rare entity which originates in the sphenoid sinus cavity and extends into the choana via the ostium. Symptoms associated with sphenochoanal polyp include nasal obstruction and headache. Endoscopic examination reveals the presence of a choanal polyp, and the sphenoid origin of the polyp can be determined by CT scan. Sphenochoanal polyp cannot be distinguished from antrochoanal polyp by histological findings. The treatment of the sphenochoanal polyp involves the enlargement of the sphenoid sinus ostium and complete surgical removal. We present a case of bilateral sphenochoanal polyps with the review of the clinical, radiological, and pathological features.
