Abstract

The facial nerve decompression via mastoid is simple and easy to expose the vertical segment of the facial nerve (VFN). The objective of this study was to find out the relationship between the VFN and anatomic landmarks to facilitate prediction of the location of VFN during facial nerve decompression. The different landmarks were cochlear window (CW), oval window (OW), promontorium tympani (PT), and mastoid antrum (MA). Parameters of 140 patients (280 observations) with healthy middle ears were measured on high-resolution spiral multislice computed tomographic multiplanar reconstruction (MPR) images that were parallel to the base plane. The data gained were analyzed by statistical method and were also analyzed with respect to side and gender. The angle between orientation of VFN to the CW of the longest distance and horizontal axis was larger on the left side than that of the right (P < 0.05). Our results may provide more detailed information to predict the location of VFN during facial nerve decompression through mastoid.

摘要

经乳突面神经减压术操作简单，易于暴露面神经垂直段（VFN）。本研究的目的是找出VFN与解剖标志之间的关系，以便在面神经减压术中更准确地预测VFN的位置。不同的标志包括蜗窗（CW）、卵圆窗（OW）、鼓岬（PT）和乳突窦（MA）。在与水平面平行的高分辨率螺旋多层计算机断层扫描多平面重建（MPR）图像上，测量了140例中耳健康患者（280个观察对象）的各项参数。所得数据采用统计学方法进行分析，并按左右侧和性别进行分析。VFN至最长距离的蜗窗方向与水平轴之间的夹角左侧大于右侧（P<0.05）。我们的研究结果可为经乳突面神经减压术中预测VFN的位置提供更详细的信息。
