title: [Transnasal endoscopic surgery].
abstract: We have performed operations of transnasal endoscopic surgery successfully. This study was intended to analyze and discuss the method of operation on the ostium meatus unit, the removal of polyps in sphenoethmoidal recess or superior turbinate and our viewpoint of ethmoid sinus operation. We conclude that (1) the 70 degree nasal endoscope is the main instrument in endoscopy; (2) an endoscope and a head lamp should be used alternatively in order to proceed the operation quickly and smoothly; (3) the bone wall should not be broken rashly and a good drainage should be the main purpose in ethmoid sinus operation; (4) a bipolar electrical coagulator, a laser and other techniques should be used to make operative fields clear.
