Abstract

The middle meatal mucosa, uncinate process, infundibulum, superior meatal mucosa and sphenoethmoidal recess are the most common sites of origin of polyps. Polyps originating from the mucosa of the nasal septum are rare. We report herein on a case of bilateral nasal polyps originating from the nasal septum.<br>Case report: A 39-year-old woman visited our hospital complaining of nasal obstruction. The patient had lateral nasal septal polyposis which filled nasal vestibule.<br>She had a history of perennial allergy rhinitis and asthma. Computed tomography (CT) showed nasal septal polyposis filling the nasal pathway without bone destruction.<br>She was treated with a corticosteroid nasal spray, oral antihistamine therapy and oral clarithromycin therapy for 3 months but without any improvement in her symptoms.<br>As nasal septal polyps are a rare entity and the potential of malignant disease was considered, we performed a biopsy. Nasal polyps with an inflammatory response were diagnosed based on the histopathological examination. Endoscopic surgery was performed using a microdebrider under general anesthesia.<br>After surgery, the patient was treated with oral antihistamine therapy, oral steroid therapy and a corticosteroid nasal spray. At 2 weeks postoperatively, she discontinued the oral steroid use. At 6 months postoperatively, she discontinued the oral antihistamine drug.<br>After 24 months follow up, there was no evidence of recurrence.
