【Abstract】 The article is based on 80 dried specimens of temporal bones unearthed fromKunming area.On the level beneath the pyramidal eminence,a groove was chis-eled to observe the hidden position and depth of the facial nerve (?)in this siteand to study the relationship among the facial duct,facial recess and tympanic sinus as well as their variation forms.The method to forecast the hidden posi-tion and depth of the facial nerve during operation was presented,which hasbeen proved to be of clinical value by 90 cases undergone the operations.更多还原
