Vestibular dysfunction occasionally accompanies sensorineural hearing loss (SNHL) due to anatomical proximity of cochlea and vestibule. The aim of the present study was to evaluate the vestibular system objectively and subjectively in 40-to 65-year-old individuals with and without SNHL.
This study included participants of both sexes, between the ages of 40 and 65 years old. There were 31 participants with SNHL and 31 control participants. First of all, participants were grouped in the control and SNHL groups based on the results of their hearing test, which included audiometry and immitance evaluation. Subsequently, for vestibular evaluation, each participant was evaluated subjective with "Dizziness Handicap Inventory" (DHI) as well as with objective tests battery that included positional tests with videonystagmogrophy (VNG) and vestibuloocular reflex (VOR) assessment using the vestibular head impulse test (vHIT).
Peripheral nystagmus was found to be significantly higher in patients with SNHL based on the head shake and positional tests (p<0.05). There was a positive correlation between DHI scores and positional test findings of the participants with SNHL (p<0.05). When the VHIT VOR gain values were compared between groups, there was no significant difference (p<0.05).
In our study, vestibular involvement was frequently observed in 40- to 65-year-old individuals with SNHL. Therefore, vestibular evaluation should be considered along with the assessment of hearing in individuals with SNHL who are over 40 years old.
由于耳蜗和前庭在解剖位置上相邻，前庭功能障碍偶尔会伴随感音神经性听力损失（SNHL）出现。本研究的目的是对40至65岁有或没有SNHL的个体的前庭系统进行客观和主观评估。
本研究纳入了年龄在40至65岁之间的男女参与者。有31名SNHL参与者和31名对照参与者。首先，根据听力测试结果将参与者分为对照组和SNHL组，听力测试包括听力测定和声导抗评估。随后，为了进行前庭评估，对每位参与者使用“头晕残障量表”（DHI）进行主观评估，并使用包括视频眼震图（VNG）的位置测试和使用前庭头脉冲试验（vHIT）进行前庭眼反射（VOR）评估的客观测试组合进行评估。
根据摇头和位置测试，发现SNHL患者的外周性眼震明显更高（p<0.05）。SNHL参与者的DHI评分与位置测试结果之间存在正相关（p<0.05）。当比较两组之间的vHIT VOR增益值时，没有显著差异（p<0.05）。
在我们的研究中，40至65岁的SNHL个体中经常观察到前庭受累。因此，对于40岁以上的SNHL个体，在评估听力的同时应考虑进行前庭评估。
