Excision of benign neoplasms in ethmoid sinuses under nasal endoscope;

Methods In 25 cases with the explosive orbital fracture,nasal endoscope was used to remove the ethmoid sinus atrial septum and the traumatic orbital lamina,temponaded the ethmoidal operated cavity with the prepared porous silica-gel path whose convex outward,then pressed and reposited the orbital lamia.

Methods Ethmoid sinuses of 250 cases were scanned transversally by MSCT with coronal and sagittal views were reconstructed.

Observation relationship of ethmoid cell and sphenoid sinus with use of spiral CT;

Applied anatomy of decompression of optic canal through ethmoidal sinus;

Microsurgical anatomy of lateral wall of ethmoidal sinus;

Objective: To study the anatomy of ethmoidal artery in the ethmoid and to provide instructions for endoscopic sinus surgery.

Forobtaining the bets result,the height of maxillary-ethmoid and the height from the up-edgeof maxillary-ethmoid plate to the roof of posterior ethmoid were measured.

Objective: According to the clinical requirement of endoscopic ethmoid sinus surgery ,a research has been performed to explore a secure and effective surgical landmarks and a safe border for the endoscopic ethmoid sinus surgery by means of the applied anatomy and nasal endoscopic ethmoidal anatomy and CT scans.
