摘要： 目的探讨神经导航在经岩骨幕上下联合入路中的作用,为经岩骨幕上下联合入路中保护面神经管提供解剖研究。方法 8具16侧成人汉族尸头模拟在神经导航指引下经岩骨幕上下联合入路的手术操作,测量乳突最外点到面神经管各段的距离,解剖面神经管,观测面神经管的解剖及其与重要结构的关系。结果 (1)所在面神经管均成功导航,成功率100%,总体误差<0.9 mm。(2)面神经管岩骨段可划分为三段:前庭段(迷路段)最短,长径(3.6±1.2) mm、管径(1.2±0.3)mm;鼓室段居中,长径(11.2±2.5)mm、管径(1.4±0.1)mm;乳突段(垂直段)最长,长径(16.1±3.6)mm、管径(1.7±0.2)mm。结论神经导航可应用指导保护面神经管;熟悉面神经管的解剖特点有利于术中保护面神经。

Abstract: Objective To study the value of neuronavigation in the transpetroal approach, and to provide anatomic data for the protection of the nerves in the facial nerve canal (FNC) during surgeries. Methods Simulated surgery through the transpetroal approach was performed on 16 sides of 8 adult cadaver heads with the assistance by neuronavigation. The anatomy of the facial nerve and the relationship of related structures were observed and the distances from the utmost external edge of the mastoid to different segments of the FNC were measured. Results Neuronavigation was successful with all the FNC, with the mean error of less than 0.9 mm. The FNC could be divided into 3 segments, the labyrinthine, the tympanic and the mastoid segments, stretching 3.6±1.2 mm, 11.2±2.5 mm and 16.1±3.6 mm respectively and with diameters of 1.2±0.3 mm, 1.4±0.1 mm and 1.7±0.2 mm, respectively. Conclusion Neuronavigation may help protect the FNC during surgical procedures, and a thorough knowledge of the anatomic features of the FNC can be significant for preservation of the facial nerves.
