美尼尔病时常见混合性聋是大家所公认的。据称其传导性聋成份乃内耳流体动力学改变所致。由于迷路内压增高而改变了迷路窗的传音条件并减少了耳蜗基底膜波动的幅度。有人在动物身上通过耳蜗微音效应(CM)描记法研究过此等问题。迷路内压升到15~20,有时达25~30mmHg时,则外淋巴间隙、内淋巴间隙以及蛛网膜下腔等处均见液压升高,并常出现CM减弱10~20 dB。如此升压持续30分钟以上时,虽压力恢
Meniere’s disease is commonly recognized as mixed hearing loss. The allegedly conductive deafness component is due to changes in the inner ear hydrodynamic. As a result of increased labyrinthine pressure changes labyrinthine acoustic conditions and reduce the amplitude of cochlear basement membrane fluctuations. These problems have been studied on animals by cochlear microphones (CM) tracings. Lost pressure rose to 15 to 20, and sometimes up to 25 ~ 30mmHg, then the perilymph, endolymphatic and subarachnoid spaces such as hydraulic pressure increase, and often appear CM weakened 10 ~ 20 dB. So boost for more than 30 minutes, although the pressure recovery
