Application of MSCT in the Temporal Segment of Facial Nerve Canal

多层螺旋CT曲面重建显示 颞骨内面神经 管 的 临床应用价值

Contrast study between coronal sectional anatomy and HRCT image of temporal bone including the inner segment of facial nerve canal and adjacent structures

面神经 管及周围结构在冠状薄层切片和 HRCT上的对照研究

The natural cavity and foramen in the temporal bone such as the external auditory canal tympanic cavity internal auditory canal vestibular duct cochlear duct and the mastoid process segment of facial nerve became narrowed due to fibrous dysplasia .

骨纤维异常增殖症可导致 颞骨的自然腔隙、孔道狭窄，如 外耳 道、鼓室腔、内听道、前庭导水管、耳蜗导水管及面神经乳突段骨管；

Methods On 60 sides adult temporal bone specimens the related anatomic structures were well exposed by opening the mastoid cavity and removing the lateral wall of external auditory canal and tympanic scutum .

方法利用成人60侧 颞骨标本，用牙科钻磨开乳突腔，打开 外耳道外侧壁和鼓室盾板，充分暴露后鼓室入路手术中有关的解剖结构。
