The temporal bones of three cases of acoustic neurinoma are described to illustrate histopathological features of inner ear lesions due to chronic partial obstruction of blood circulation by the tumor in the internal auditory meatus. Degenerative changes in the inner ear due to acoustic neurinoma were evaluated and compared with changes in the opposite ear. The main pathological findings in the inner ear which were attributed to the tumor were degeneration of nerve fibers and of ganglion cells, degeneration of the stria vascularis, degeneration of the tectorial membrane, fibrosis and ossification of a semicircular canal. Fairly good preservation of sensory cells was observed in the presence of total degeneration of nerve fibers and ganglion cells and subtotal degeneration of the stria vascularis.
描述了3例听神经瘤患者的颞骨，以说明由于肿瘤在内耳道内慢性部分阻塞血液循环而导致的内耳病变的组织病理学特征。评估了听神经瘤导致的内耳退行性变化，并与对侧耳的变化进行了比较。内耳中归因于肿瘤的主要病理发现是神经纤维和神经节细胞的变性、血管纹的变性、盖膜的变性、半规管的纤维化和骨化。在神经纤维和神经节细胞完全变性以及血管纹部分变性的情况下，观察到感觉细胞保存相当良好。
