Abstract:
Choanal polyps (CP) are benign mucous tumours that usually originate in the mucosa of the maxillary sinus, and hence are termed antrochoanal polyps. CP rarely originates in the mucosa of other nasal structures and paranasal sinuses. The purpose of this brief clinical communication is to present six cases of CP originating in the sphenoidal sinus and termed sphenochoanal polyps (SCP).
