[Endoscopic treatment of maxillary sinus cysts].

Maxillary sinus cysts are common lesions usually found in routine x-rays of the teeth and sinuses. Although most patients are asymptomatic, there may be headache or periorbital or facial pain. Traditionally, these cysts have been treated by puncture and aspiration, or excision via intranasal antrostomy or Caldwell-Luc operation 23 patients with maxillary sinus cysts who presented with facial pain were treated by endoscopic surgery. During followup of 1 year the cyst recurred in only 1 of the patients (after 2 months). We recommend endoscopic removal of maxillary sinus cysts as the treatment of choice.
