Sphenochoanal Polyp: A Rare Entity with Review of Literature

Sphenochoanal polyp is a rare form of choanal polyp which originates from the sphenoid sinus and extends to posterior choanae via sphenoethmoidal recess. Its occurrence is extremely rare. They can be easily mistaken for antrochoanal polyp. Symptomatically, it is similar to antrochoanal polyp. So, adequate preoperative evaluation with diagnostic nasal endoscopy and computed tomography or magnetic resonance imaging is necessary for correct diagnosis and planning of appropriate surgical procedures. Surgical resection is the treatment modality of choice. We here present a case of sphenochoanal polyp along with review of literature.
