The compensatory process of vestibular neuronitis in 7 patients was followed up and evaluated using the Combined Galvanic Test (CGT) and other neuro-otological data. CGT is the simultaneous recording of both galvanic eye movement (GEM) and galvanic body sway (GBS), and has proved to be reliable in the diagnosis of retrolabyrinthine disorders. The results were as follows: The subjective symptoms remained in 3 cases from 1 month to 1 year. The recovery of the GBS response was seen earlier than that of both GEM and caloric responses. The recovery of GEM and caloric responses was observed at almost the same time. We observed the favorable recovery process of caloric response and GEM response in some cases which had recovery of GBS response within 4 weeks and suggest that the system of GBS response is different from that of GEM and caloric response. However, the systems of the latter two may be the same. We assume that the recovery of GBS response is earlier than that of GEM and caloric responses because the otolithic system recovers more easily than the semicircular canal system. The CGT and caloric test were reliable in examining the compensatory process of vestibular neuronitis.
对7例前庭神经炎患者的代偿过程进行随访，并使用联合电刺激试验（CGT）及其他神经耳科学数据进行评估。CGT是同时记录电刺激眼动（GEM）和电刺激身体摆动（GBS），已被证明在诊断迷路后疾病方面可靠。结果如下：3例患者的主观症状持续1个月至1年。GBS反应的恢复早于GEM和冷热试验反应。GEM和冷热试验反应的恢复几乎同时出现。我们观察到一些在4周内GBS反应恢复的病例中冷热试验反应和GEM反应有良好的恢复过程，并提示GBS反应系统与GEM和冷热试验反应系统不同。然而，后两者的系统可能相同。我们推测GBS反应的恢复早于GEM和冷热试验反应，是因为耳石系统比半规管系统更容易恢复。CGT和冷热试验在检查前庭神经炎的代偿过程方面可靠。
