METHODS: Retrospective study.
METHODS: Tertiary referral center.
METHODS: A total of 226 individuals diagnosed with unilateral definite SSNHL were hospitalized. The assessment included a comprehensive evaluation of medical history, pure-tone test, acoustic impedance, positional test, video nystagmography (VNG), vHIT, vestibular evoked myogenic potentials (VEMPs) and magnetic resonance.
METHODS: vHIT, VNG, cVEMP, oVEMP. Statistical analysis was performed with SPSS version 22.0 for Windows.
METHODS: The asymmetry values, gain, and pathological saccades of the vHIT.
RESULTS: The abnormal gain of vHIT in anterior, horizontal, and posterior canal in SSNHL patients with vertigo were revealed in 20 of 112 (17.9%), 24 of 112 (21.4%), and 60 of 112 (53.6%), respectively. The vHIT pathological saccades (overt + covert) of anterior, horizontal, and posterior canal in SSNHL patients with vertigo were observed in 5 of 112 (4.6%), 52 of 112 (46.4%), and 58 of 112 (51.8%), respectively. Multivariate analysis indicated that the prognosis of patients with vertigo was correlated with vHIT gain of posterior canal, pathological saccade in horizontal canal, asymmetric ratio of horizontal canal gain, asymmetric ratio of posterior canal gain, Canal paresis (%) on caloric test and spontaneous nystagmus.
CONCLUSIONS: In the vHIT of patients with SSNHL with vertigo, the posterior canal is most easily affected. Reduced gain of posterior canal, pathological saccade of horizontal canal, and larger asymmetric gain of posterior canal and horizontal canal may be negative prognostic factors.
方法:回顾性研究。
方法:三级转诊中心。
方法:共226例诊断为单侧确定的SSNHL患者住院。评估包括对病史的全面评估,纯音测试,声阻抗,位置测试,视频眼震描记术(VNG),vHIT,前庭诱发肌源性电位(VEMPs)和磁共振。
方法:vHIT,VNG,cVEMP,OVEMP.使用SPSS版本22.0forWindows进行统计分析。
方法:不对称值,增益,和病理性扫视。
结果:前段vHIT异常增益,水平,在SSNHL伴眩晕患者中,有20例(17.9%)出现后管,112人中的24人(21.4%),和112人中的60人(53.6%),分别。前部的vHIT病理性扫视(公开+隐蔽),水平,在SSNHL伴眩晕的患者中,有5例(4.6%),112人中的52人(46.4%),112人中有58人(51.8%),分别。多因素分析显示眩晕患者的预后与后管vHIT增益相关,水平运河的病理性扫视,水平运河增益的不对称比,后管增益的不对称比率,热量测试和自发性眼球震颤的运河麻痹(%)。
结论:在SSNHL伴眩晕患者的vHIT中,后道最容易受累。后管增益降低,水平运河的病理性扫视,后管和水平管的不对称增益较大可能是不良预后因素。
