A Case of Choanal Polyp Originated from the Inferior Turbinate

Abstract

The choanal polyp, originating from inferior turbinate, is known to be extremely rare. We report a case of a 65-year-old woman who was treated for choanal polyp originating from inferior turbinate. She had felt left nasal obstruction for two weeks. In the endoscopic examination, polypoid tissue covered with the mucopurulent discharge was observed filling the left inferior meatus. An ovoid homogenous enhancing lesion in the left posterior nasal cavity around the inferior turbinate was observed on CT and MRI. Endoscopic mass excision with partial inferior turbinectomy was performed under general anesthesia. The pedicle of the polyp was observed on the posterior side of the inferior turbinate. Complete resection including the mucosa around the pedicle of the choanal polyp was performed. The patient was followed up for seven months without any recurrence or complications.
