Giant Antrochoanal Polyp in a Six-years-old Boy: A Case Report and Literature Review

Abstract

Antrochoanal polyps are more prevalent in children than adults. Unilateral nasal obstruction and rhinorrhea are usually the features of unilateral antrochoanal polyps. Bilateral nasal obstruction can be a feature of antrochoanal polyp if it is large and obstruct both choanae. The giant antrochoanal polyp is rarely reported in the literature. We are reporting this scenario of giant left antrochoanal polyp in a 6-years-old boy who presented with bilateral nasal obstruction, nasal and postnasal mucopurulent discharge, hypo-nasal speech, mouth breathing, snoring, and obstructive sleep apnea syndrome. The physical examination revealed a mass seen in the oropharynx behind the uvula. Further examination by nasal endoscopy, computerized tomography, and histopathological evaluation of the excised polyp have confirmed the diagnosis of an antrochoanal polyp. Although this entity is not commonly seen in daily clinical practice, careful assessment is needed to not miss the diagnosis for early treatment to avoid unwanted complications.
