Technique for Endoscopic Endonasal Sinus Surgery

Abstract

Endoscopy enables us to avoid complications and achieve complete surgery of the ethmoid sinus, nasofrontal duct, and fontanelle under clear observation. By connecting a CCD camera, a surgeon can carry out an operation while watching the image on a TV monitor. Rigid 0° and 70° endoscopes are used. The 0° endoscope is selected for the ethmoid portion of the operation, and the 70° endoscope is used for treatment of the nasofrontal duct and the fontanelle. Use of various forceps has made it possible to treat the nasofrontal duct and the fontanelle and to establish a wide communication. In practice, intranasal procedures are conducted close to the anatomical location of the ground lamella (gl) in the ethmoid sinus. We discussed our technique for endoscopic endonasal sinus surgery for pansinusitis.
