Six Cases of Cysts of the Posterior Paranasal Sinuses with Visual Disturbance

Abstract

Six patients with cysts in the posterior paranasal sinuses who compained of visual disturbance are reported. All of them had previously undergone sinus surgery (mean,20.3years). All of them were treated via an endonasal approach under local anesthesia. In five, the visual acuity and the visual field was improved after surgery. However, one did not recover the visual field despite gross improvement in the visual acuity. Computed tomography was very useful to localize the lesion, and the image amplifier was useful to indicate the sphenoid sinus.
