A Case of Antral Choanal Polyp

Abstract

We describe a case of antrochoanal polyp. Computed tomography revealed soft tissue density areas in the right maxillary sinus without bone defects and at the nasopharynx with some air spaces between the pterygoid process. When the specimen was obtained for pathohistological study, the polyp bled and angiofibroma could not be denied. Following arterial embolization, polypectomy and Caldwell-Luc's operation were performed. Cases of antrochoanal polyp angling to the mesopharynx must be distinguished from other diseases. Since antrochoanal polyp and nasopharyngeal angiofibroma show many similar clinical features, if angiofibroma is present, careful treatment is needed.
