Clinical characteristics of antrochoanal polyps: case reports and a review of literature

Abstract

The paper describes two clinical cases of antrochoanal polyps (ACP): 1) a giant ACP caused bilateral nasal obstruction, rhinorrhea, and dyspnea in the supine position in a 17-year-old female and 2) transformation of an antral polyp to ACP could be traced in a 17-year-old male. In both cases, the diagnosis was made by endoscopy of the nasal cavity and computed tomography of the paranasal sinuses and verified by histopathological examination of the removed polyps. In the former case, a combined (endonasal and transoral) approach was applied due to the unusual sizes of the polyp for its complete removal. The paper discusses the clinical characteristics of ACPs and the data of recent studies of their etiopathogenesis and surgical treatment.
