镫骨及其周围结构尤其是镫骨和面神经管之间关系的解剖变异是影响耳硬化症手术的重要因素之一。作者应用手术显微镜对200个正常成人颞骨的镫骨区作了详细的研究,其中包括57个新鲜颞骨,其余143个标本分别作矢状面(50)、冠状面(60)和水平面(33)进行测量。结果表明,镫骨在前庭窗窝的位置有三种类型:垂直位于正中(10.4%);向鼓岬方向倾斜(80.8%)及向上方的面神经管倾斜(8.8%)。前庭窗窝上壁仅由面神经管凸起构成者占45.8%,由外侧的
Anatomical variation of the relationship between the stapes and their surrounding structures, especially the stapes and facial nerve tubes, is one of the important factors affecting the operation of otosclerosis. The authors performed a detailed study of the stapedix region of 200 normal adult temporal bones using a surgical microscope, including 57 fresh temporal bones and the remaining 143 specimens for sagittal (50), coronal (60) and horizontal (33) Make measurements. The results showed that there are three types of stapes in the vestibular window: vertical in the middle (10.4%); tilt to promontory head (80.8%) and upturned facial canal (8.8%). Vestibular wall on the wall only by the facial neural tube raised constitute 45.8%, from the outside
