In patients with severe mental retardation, special surgical treatment should be considered.
A giant antrochoanal polyp in a 31-years-old man with severe mental retardation is reported. The polyp discovered accidentally after the patient began exhibiting snore and rhinorrhea, and after a few months observation weight loss due to dysphagia was noted. Surgical treatment without nasal tamponade was planned, since we were concerned that the patient would be unable to cooperate with the necessary postoperative treatment; embolization of a maxillary artery, functional endoscopic sinus surgery (FESS) and Argon Plasma Coagulation. Postoperatively, the patient's symptoms and the radiological findings of his sinuses were improved.
