Abstract:
Sinochoanal polyp is an inflammatory polyp that originates in the paranasal sinus, passes through a sinus ostium, and extends into the choana. While antrochoanal polyp is the most common type of sinochoanal polyp, sphenochoanal polyp is rare and ethmochoanal polyp is extremely more rare to find. To minimize postsurgical recurrence, it is essential to completely remove the polyp together with the base of its origin. We have recently experienced and successfully managed three cases of ethmochoanal polyp by endoscopic sinus surgery. It was difficult to histologically differentiate ethmochoanal polyp from sinonasal polyps associated with chronic rhinosinusitis. For this reason, ethmochoanal polyp should be suspected and completely removed together with the base of its origin when a large polyp originates from the ethmoid sinus and extends into the choana. Now we report three cases of ethmochoanal polyp with a brief review of the related literatures.
