一般认为前庭神经炎仅是单侧前庭神经或终器的障碍引起的纯前庭症状。表现为突发性眩晕,但无听力损失或中枢障碍。1982年Wennmc和Pyykk(?)发现1/3的前庭神经炎病人有视动异常,认为有脑干或小脑的损伤。1979年Aantaa和Virolainen检查了43例前庭神经炎病人,虽然50%患者三年后仍有轻微听力损失,但听阈仍不出正常范围。1983年Bergenius和Borg检查了19例前庭神经炎病人,约半数显示镫骨肌反射阈值升高。作者们认为前庭终器和耳蜗来自同一血液供给,并有相同的构型成份,所以,有严重的前庭 Vestibular neuritis is generally considered to be a purely vestibular symptom caused by a disorder of the unilateral vestibular nerve or terminator. The performance of sudden dizziness, but no hearing loss or central disorder. In 1982, Wennmc and Pyykk (?) Found that one third of patients with vestibular neuritis had abnormal visual acuity, suggesting damage to the brainstem or cerebellum. In 1979, Aantaa and Virolainen examined 43 patients with vestibular neuritis. Although 50% had mild hearing loss after three years, the hearing threshold was still outside the normal range. In 1983, Bergenius and Borg examined 19 patients with vestibular neuritis, and about half showed an elevated stapedius reflex threshold. The authors believe that the forearm and cochlear end of the same blood supply, and the same configuration, so there is a serious vestibule
