Clinical studies were conducted on 39 patients with an idiopathic paranasal cyst at Mie University Hospital over 20 years, between January 1983 and December 2002. Cases included 14 ethomoid sinus, 11 frontal sinus, 6 maxillary sinus, 4 sphenoid sinus and 4 frontal and ethomoid sinus. Most of the cases had a simple cyst, and only 2 cases had multiple cysts. Swelling of the eyelid, exopthalmos and double vision were frequently noted in frontal cysts, ethmoid cysts and frontoethmoid cysts. Cheek swelling or pain was noted in maxillary sinus cysts. Three cases of four sphenoid cysts were found accidentally on MRI without ocular symptoms. Ethmoid and sphenoid cysts were treated by intranasal operation and frontal cysts were done by rhinotomy. Maxillary cysts were treated intranasally or by rhinotomy by opening the anterior wall of the maxillary sinus. Prognoses of most cases were good, while 3 cases of ethmoid cyst re-appeared.
