前庭功能与突发性聋预后的相关性分析

目的 探讨突发性聋（简称突聋）患者眩晕、前庭功能的状况与预后的关系。方法 对161例突聋患者治疗前的听力、有否眩晕及前庭功能的状况等七项参数与治疗后的听力结果建立Logistic回归模型，采用单因素方差分析、logistic回归分析和卡方检验等多种统计学方法，分析各参数与突聋预后间的关系。结果 单因素方差分析及卡方检验均显示突聋的预后与治疗前的听力显著相关（P〈0．01）；logistic回归分析显示突聋的预后与治疗前的听力及眩晕显著相关（P〈0．01）；卡方检验的结果表明前庭功能正常与否各组间差异有显著统计学意义（P〈0．05），而有否眩晕仅在前庭功能异常时与突聋的预后差异有极显著统计学意义（P〈0．01），前庭功能正常时有否眩晕与突聋的预后无关（P〉0．05）。结论 突聋患者的听力损失越重，预后则越差；前庭功能正常与否对突聋的预后有一定的影响；而有无眩晕仅在前庭功能异常时对突聋的预后有较大的影响。听力损失的程度与前庭功能及有无眩晕无关，眩晕与前庭功能也无关，突聋伴发的眩晕不一定是前庭损害的结果。

The Correlation between Normal or Abnormal Vestibule Function and Prognosis of the Sudden Deafness

Objective To study the correlation between prognosis and vertigo and status of the vestibule functions with the patients of the sudden deafness (SD).Methods For 161 patients of the SD, the parameters of the hearing before treatment, vertigo and vestibule functions, were analyzed to establish a statistic model by means of Logistic regression with single factor analysis of variance, Logistic regression analysis and Chi square test.Results The single factor analysis of variance and Chi square revealed statistical differences between prognosis of the SD and hearing before treatment(P<0.01). Logistic regression showed prognosis of the SD correlation with hearing before treatment and vertigo(P<0.01). Chi square test showed that caloric test revealed statistical difference between each groups(P<0.05). When caloric test was abnormal, with or without vertigo statistically different results were found between prognosis of the SD by Chi square(P<0.01); however, when caloric test was normal, no statistical difference was found(P>0.05).Conclusion If the patients with SD had more severe hearing loss, the prognosis would be less successful. The normal or abnormal caloric tests had influence for the prognosis of the SD, but vertigo showed influence on prognosis only when caloric test was abnormal. The degree of hearing loss was not related to that of vertigo or vestibule functions while the sudden deafness accompanied with vertigo was not due to the damage of vestibular functions.
