Simultaneous antrochoanal and sphenochoanal polyps: a rare clinical entity.

Choanal polyps almost always appear as solitary growths and most commonly arise from the maxillary sinus. Sphenochoanal and ethmoidochoanal polyps are extremely rare. Co-existence of more than one choanal polyp is even more infrequent. We present a patient with an antrochoanal and an accompanying sphenochoanal polyp for the first time in the literature. We discuss the clinical presentation, pathogenesis and surgical management of this rare clinical entity.
