Choanal Polyps of Unusual Presentation a A Series of 4 Cases

Abstract

Choanal polyps are the solitary benign tumours that originate from the sinus or nasal mucosa projecting into the nasal cavity, choana and even up to the oropharynx. The exact aetiology of choanal polyps is unknown. Several theories have been formulated in the past years to describe the aetiology of choanal polyps. It is more commonly seen in young age patients. In young patients with a history of unilateral progressive nasal obstruction, it is always necessary to rule out choanal polyp. Although antrochoanal polyps are the most common, it is not a rule. Choanal polyp can also originate from sphenoid sinus and ethmoidal sinus, nasal septum and lateral wall of nose. Rare cases of these presentations are also reported. Endoscopy assisted surgery is the treatment of choice. Endoscopy can also be used as a diagnostic guide when CT scan findings are inconclusive in differentiating antrochoanal and sphenochoanal polyp. One must also keep in mind the other possible differential diagnosis.
