摘　　要：目的探讨外周前庭性眩晕半规管低、高频区损伤特点。方法87例外周前庭性眩晕患者均进行冷热水试验(CaT)、视频头脉冲试验(vHIT)检查。结果突发性耳聋伴眩晕组50例,其中CaT异常率58.0%、vHIT异常率38.0%、总异常率70.0%。梅尼埃病组15例,其中CaT异常率60.0%、vHIT异常率26.7%、总异常率66.7%。良性阵发性位置性眩晕组19例,其中CaT异常率36.8%、vHIT异常率5.1%、总异常率36.8%。前庭神经炎组3例,其中CaT异常率100%,vHIT异常率66.7%,总异常率100%。结论外周前庭性眩晕患者半规管功能存在不同程度的损伤,CaT和vHIT联合应用能够全面、客观地了解前庭损伤的情况,提高半规管功能损伤的检出率,对外周前庭性眩晕的诊治有重要的参考价值。Objective To explore the low and high frequency characteristics of vestibular vertigo.Methods Clinical data of 87 patients with vestibular vertigo were retrospectively analyzed by CaT and vHIT examination.Results Among the 50 patients with sudden hearing loss with vertigo 70.0% were abnormal detection,58.0% and 38.0% showed abnormal CaT and vHIT respectively.Among the 15 patients with Meniere's disease 66.7% were abnormal detection,60.0% and 26.7% showed abnormal CaT and vHIT respectively.Among the 19 patients with BPPV 36.8% were abnormal detection,36.8% and 5.1% showed abnormal CaT and vHIT respectively.Among the 3 patients with vestibular neuritis 100% were abnormal detection,100% and 66.7% showed abnormal CaT and vHIT respectively.Conclusion Different frequency dysfunctions were found in vestibular vertigo.Combined CaT and vHIT examination can improve evaluating vestibular function and help guiding further treatment.
