Paranasal sinus-operations using an endoscope, especially for patients with sinusitis.

Forty patients with paranasal sinus disorders were operated on by using an endoscope with VTR system.For the paranasal sinus focus, otorhinolarygologists conventionally conduct the operation at the ethmoidal sinus and sphenoidal sinus by the endonasal method, extranasal method or transmaxillary method.Considering the VTR system, we have recently been carrying out operations using videorecorder under a rigid endoscope with fiberscopic lighting.We demonstrated 3 cases, in which paranasal sinus operations were performed. Our endoscopic endonasal surgery with the aid of rigid endoscopes, aims at the primary focus in the anterior ethmoid, to clear stenotic clefts, infected ethmoidal cell mucosa and tumor.Excellent results have been achieved with this method, developed by Massenklinger, Stammberger, Yamashita, and Ashikawa. In future, use of endoscopy with VTR in the intranasal region will be prevalent as a routine operation.
