title: [Surgical anatomy of the middle meatus and ethmoid].
abstract: The evolution of rhino-sinusal endoscopy and the progress in endonasal surgery under endoscopic guidance, justifies a review of the ethmoid anatomy. A simple and logical scheme of the ethmoid bone is presented. The observer has to develop an "endoscopic eye" since the panoramic view offered by the optics modifies the image. Special attention is drawn upon the endoscopic anatomical fine points in the crucial area of the "bullar circus". These are necessary guides in surgical practice.
