Giant antrochoanal polyp protruding into the nasopharynx

Choanal polyps are benign, unilateral, soft tissue masses that grow towards the choana and that may further extend into the nasopharynx or even down to the oropharynx. The main symptoms in patients with an antrochoanal polyp are progressive nasal obstruction, rhinorrhea, snoring, and nasal discharge. Large choanal polyps reaching the nasopharynx or oropharynx are rare. Therefore, the aim of this article is to present and discuss a case of large choanal polyp that extended and occluded the nasopharynx.
