引起眩晕、平衡障碍的解剖部位,在末梢前庭系统有内耳,进一步说来是半规管和耳石器,还有联络中枢的前庭神经;在中枢神经系统中,小脑、脑干是重要的眩晕发生地,其中,特别是在系统发生学上,以原前庭神经核为中心的脑干背侧部及小脑正中部,对眩晕的发生起着重要的作用。一、中耳炎移行的内耳炎中耳炎的炎症波及内耳时,其中大部分病例是胆脂瘤型中耳炎。胆脂瘤破坏骨质,炎症通过前庭窗、
Caused by vertigo, balance the anatomy of the obstacle in the distal vestibular system has the inner ear, the semicircular canal and the otolith, and the vestibular nerve contact center; in the central nervous system, the cerebellum, brain stem is an important place of vertigo, Among them, especially in phylogenetics, the dorsal part of the brain stem and the middle part of the cerebellum centering on the original vestibular nucleus play an important role in the occurrence of dizziness. First, otitis media migratory otitis media inflammation spread to the inner ear, most of which cases are cholesteatoma otitis media. Cholesteatoma destruction of bone, inflammation through the vestibular window,
