随着影像诊断学和耳显微外科的不断发展,对内耳道疾病已有了新的认识。一些原因不明的感觉神经性聋、耳鸣、眩晕以及面瘫、面肌痉挛等亦应考虑到与内耳道疾病可能有关。现代CT扫描技术能得到冠状、矢状和横断面高分辩率的影像,可以作1.0～1.5 m m间距的切面扫描,从中观察到一些微小的结构,如岩乳管、前庭导水管和耳蜗导水管等。核磁共振或称磁共振已越来越多地应用于耳鼻喉科临床。Barker曾用以观察了骨迷路的正常解剖,发现可显示内耳道的神经、耳蜗、螺旋神经节及前庭器。
With the continuous development of imaging diagnostics and ear microsurgery, there is a new understanding of the diseases of the inner ear canal. Some unexplained sensory nerve deafness, tinnitus, dizziness and facial paralysis, hemifacial spasm, etc. should also be taken into account may be related to diseases of the inner ear canal. Modern CT scans result in high-resolution images of the coronal, sagittal and cross-sectional areas that can be scanned at 1.0 to 1.5 mm intervals with minor structures such as petrous duct, vestibular aqueducts, and cochlear aqueducts Wait. Nuclear magnetic resonance or magnetic resonance has been increasingly used in ENT clinical. Barker had been used to observe the normal anatomy of the bony labyrinth and found to show nerves, cochlea, spiral ganglia and vestibular vessels in the inner ear canal.
