Sphenochoanal polyp: Current diagnosis and managementAbstractChoanal polyps arise from inflamed, edematous mucosa in the paranasal sinuses. They extend into the choana and cause nasal obstruction and mouth breathing. In most cases, these polyps arise in themaxillary sinus, but rare cases of origin in thesphenoid sinusand other nasal structures have been reported. The presence of a choanal polyp in an atypical location can lead to diagnostic confusion and exploration of the wrong sinus at surgery. The author reports the case of a 15-year-old girl who was diagnosed with a sphenochoanal polyp. The patient was successfully treated via an endoscopic surgical approach.IntroductionSphenochoanal polyps are rare, benign, solitary masses that arise from the sphenoid sinus, exit through the sphenoid ostium, pass across the sphenoethmoid recess, and extend into the choana. They were once commonly mistaken for their more common counterparts, antrochoanal polyps, which produce similar symptoms. Fortunately, advancements in imaging and endoscopic rhinology have allowed for more precise diagnoses.In this article, the author reports the case of a patient with a sphenochoanal polyp, and he discusses the clinical presentation, pathogenesis, endoscopic and radiologic evaluation, and surgical management of this clinical entity.Case reportA 15-year-old girl with persistent nasal obstruction was referred for evaluation. Her obstruction had been present for 2 years, and it primarily
