用造影剂进行内耳道脑池造影(后颅窝髓造影)对小脑脑桥角及内耳道的占位性病变,能够得到早期及较正确的诊断。为了估量这种方法对内耳道内占位性病变诊断的可靠性,特别是听神经瘤的诊断,促使作者对这一方法进行观察,经过500次以上的内耳道脑池造影术的经验,充分说明,在造影象上,内耳道充盈缺损不能确定都有肿瘤存在。方法本文分析123次内耳道脑池造影术,内53例后经手术治疗(中颅窝、经迷路及枕骨下径路),故可资比较每一例的脑池图分类与手术中的发现。
Contrast agent for the internal auditory canal brain angiography (posterior cranial fossa myelography) on the cerebellar pontoon angle and the inner ear canal lesions, can get early and more accurate diagnosis. In order to assess the reliability of this method for the diagnosis of space-occupying lesions in the auditory canal, especially the diagnosis of acoustic neuroma, the authors are prompted to observe this method, and after more than 500 experiences of intra-auricular cistern angiography, it is fully demonstrated that In the contrast image, the filling of the inner ear canal does not confirm that there is a tumor. Methods 123 cases of internal auditory canal cistern angiography were analyzed in this study. 53 cases were treated with surgery (middle cranial fossa, laparotomy, and suboccipital approach). Therefore, the classification of occipital pool and the findings in each case were compared.
