目的:为经岩部入路颅底手术提供解剖学参数。方法:观测成人的100例干燥整颅、20例颅底标本、15例尸头及36侧正常颅底CT资料;观测项目为与经岩部入路颅底手术有关的颞骨表面标志与岩部内重要结构的位置及其间距。结果:整颅及颅底内面各项测量结果左右侧比较U均<1.96,P均>0.05,颞骨内重要结构间及与表面标志间距离测量结果多数项目男女性间比较U均>1.96或>2.58,P<0.05或<0.01;颅中窝入路可以弓状隆起作标志寻认上骨半规管以确认内耳道,也可以岩大神经管裂孔为标志暴露面神经膝状神经节与迷路段确认内耳道底;磨除岩尖部骨质时可以颈动脉管后壁与内耳门内侧缘的连线作为界线。结论:颞骨表面标志点间距及颞骨岩部内重要结构间的位置关系可为经岩部入路颅底手术提供重要参考,有利于术中岩部重要结构的定位与保护。
OBJECTIVE: To provide anatomic parameters for skull base surgery via the Rock Ministry. Methods: 100 adult craniocerebral skull specimens, 20 skull base specimens, 15 cadaver heads and 36 normal skull base CT data were observed. The observation items were the temporal bone surface markers related to skull base surgery and the significant The location of the structure and its spacing. Results: The left and right sides of the measurement results on the left and right sides of the cranial and the skull base were all less than 1.96, P> 0.05. The distance between the major structures in the temporal bone and the distance between the surface markers was significantly higher than that in the majority of subjects (U> 1.96 or> 2.58, P <0.05 or <0.01; cranial fossa approach arch can be marked as a sign to identify the supraspinatus to confirm the internal auditory canal, the petrous neural tube can also be marked as a sign of facial nerve geniculate ganglion and the lost section to confirm the internal auditory canal At the end; grinding rock tip bone can be carotid artery posterior wall and the inner ear inner edge of the line as a borderline. CONCLUSIONS: The temporal relationship between the surface marker points of temporal bone and the important structures in the petrous bone can provide an important reference for the skull base surgery via the petrous tract, which is propitious to the location and protection of important structures in the petroclival rock.
