Otolithic function is poorly understood, but vestibular-evoked myogenic potential testing has allowed the documentation of pathology in patients who complain of imbalance.
Seventy-four patients with traumatic and non-traumatic vestibular disease were sequentially assessed at a tertiary referral neuro-otology unit in a teaching hospital. A detailed history of all patients was taken and standard vestibular assessment was conducted using the technique described in the companion paper. The results of both groups of patients were analysed and the rate of abnormalities was assessed.
There was a high rate of abnormalities, including bilateral pathology, in a significant number of patients. Many patients in both groups inexplicably failed to recover.
Vestibular-evoked myogenic potentials are helpful in documenting pathology, including bilateral pathology, which is outlined in the literature as being exceedingly difficult to compensate for.
耳石功能尚未被充分了解，但前庭诱发肌源性电位测试已能记录主诉失衡患者的病理情况。
在一家教学医院的三级转诊神经耳科单位，对74例创伤性和非创伤性前庭疾病患者进行了序贯评估。采集了所有患者的详细病史，并使用配套论文中描述的技术进行了标准前庭评估。分析了两组患者的结果，并评估了异常率。
相当数量的患者存在高异常率，包括双侧病变。两组中的许多患者都莫名其妙地未能康复。
前庭诱发肌源性电位有助于记录病理情况，包括双侧病变，文献中指出双侧病变极难代偿。
