The present study aimed to measure an association between the caloric test and vestibulo-ocular reflex gain and refixation saccades in individuals with auditory neuropathy spectrum disorders.
Twenty individuals (9 males and 11 females), in the age range of 17 to 38 years, diagnosed with auditory neuropathy spectrum disorders, and 20 normal-hearing individuals (age and gender matched) participated in the study. All the individuals underwent case history, pure tone audiometry, immittance evaluation, otoacoustic emissions, auditory brainstem response, caloric tests and video head impulse tests.
All the patients with auditory neuropathy spectrum disorders in the present study had hypoactive caloric responses, which suggested peripheral vestibular lesions. The mean vestibulo-ocular reflex gain was reduced in few patients with auditory neuropathy, whereas few patients had normal vestibulo-ocular reflex gain.
The present study revealed a discrepancy between the caloric and video head impulse test results in auditory neuropathy spectrum disorders. The vestibular evaluation should be done for all patients with auditory neuropathy spectrum disorders to understand the various types of vestibular nerve lesions.
本研究旨在测量听觉神经病谱系障碍患者的冷热试验与前庭眼反射增益及重新注视扫视之间的关联。
20名年龄在17至38岁之间、被诊断为听觉神经病谱系障碍的个体(9名男性和11名女性)以及20名听力正常的个体(年龄和性别匹配)参与了本研究。所有个体均接受了病史采集、纯音听力测定、声导抗评估、耳声发射、听觉脑干反应、冷热试验和视频头脉冲试验。
本研究中所有听觉神经病谱系障碍患者的冷热反应均减弱,提示外周前庭病变。少数听觉神经病患者的前庭眼反射增益降低,而少数患者的前庭眼反射增益正常。
本研究揭示了听觉神经病谱系障碍患者冷热试验和视频头脉冲试验结果之间的差异。应对所有听觉神经病谱系障碍患者进行前庭评估,以了解前庭神经病变的各种类型。
