Two cases of sphenochoanal polyp (SCP) in children are reported. SCPs originate in the sphenoid sinus cavity, and extend into the choanal via the ostium. Symptoms associated with the syndrome include nasal blockage and headaches. Endoscopical examination reveals the presence of a choanal polyp, and the sphenoid origin of the polyp can be determined by CT scan. In cases where the middle meatus is obstructed, an opacity of the maxillary sinus is often observed. SCPs cannot be distinguished from antrochoanal polyp (ACP) by histological means. The treatment of the SCPs involves surgical removal and enlargement of the sphenoid sinus ostium. Ignorance surrounding the existence and the treatment of this syndrome may result in insufficient treatment and the consequent recurrence of the disorder.
