METHODS: The present study aimed to administer cVEMP and oVEMP to all the participants having a normal hearing with tinnitus (experimental group) and without tinnitus (Control group) and compared p13, n23 latencies and peak-to-peak amplitude of cVEMP; n10, p15 latencies of oVEMP and peak-to-peak amplitude between two groups and within tinnitus group.
RESULTS: The present study stated that there is no statistically significant difference seen in cVEMP except n23 latency of bilateral tinnitus than control group. However, there is statistically significant difference in left ear p15 latency, left ear peak-to-peak amplitude, bilateral peak-to-peak amplitude between the two groups and Right Vs Left ear peak-to-peak amplitude in within the tinnitus group was seen in oVEMP. T-test was used to compare the latencies of p13, n23, and peak-to-peak amplitude of cVEMP and n10, p15 latencies and peak-to-peak amplitude of oVEMP between the experimental and control group and within the tinnitus group.
CONCLUSIONS: There is no significant difference seen in cVEMP except n23 latency of bilateral tinnitus than control group and However, there is statistically significant difference in left ear p15 latency, left ear peak-to-peak amplitude, bilateral peak-to-peak amplitude between the two groups and Right Vs Left ear peak-to-peak amplitude in within the tinnitus group was seen in oVEMP and the current study concluded that the significant results with several parameters and no significant results with other parameters in cVEMP and oVEMP recording might be Presymptomatic tinnitus is regarded to occur in ears with normal hearing and abnormal VEMP, while asymptomatic tinnitus may occur in ears with normal VEMP. Tinnitus may be the first signs of secondary or delayed endolymphatic hydrops. If this is demonstrated to be accurate, we should anticipate that such patients will gradually develop other endolymphatic hydrops symptoms like SNHL and clinical vestibular dysfunction.
方法:本研究旨在对所有听力正常的有耳鸣(实验组)和无耳鸣(对照组)的参与者进行cVEMP和oVEMP,并比较p13,n23潜伏期和峰峰值。cVEMP的峰值振幅;n10,p15的oVEMP潜伏期和两组之间以及耳鸣组内的峰峰值振幅。
结果:本研究表明,除了双侧耳鸣的n23潜伏期外,cVEMP与对照组相比没有统计学上的显着差异。然而,左耳P15潜伏期有统计学意义的差异,左耳峰-峰振幅,两组之间的双侧峰-峰振幅和右Vs耳鸣组中的左耳峰-峰振幅在oVEMP中可见。采用T检验比较实验组和对照组之间以及耳鸣组内p13、n23的潜伏期和cVEMP和n10的峰-峰幅度、p15的潜伏期和oVEMP的峰-峰幅度。
结论:除了双侧耳鸣的n23潜伏期外,cVEMP与对照组相比没有显着差异。左耳P15潜伏期有统计学意义的差异,左耳峰-峰振幅,两组之间的双侧峰-峰幅度和右Vs耳鸣组中的左耳峰-峰幅度在oVEMP中可见,目前的研究得出结论,在cVEMP和oVEMP记录中,几个参数的显着结果和其他参数的显着结果可能是症状性耳鸣被认为发生在听力正常和VEMP异常的耳朵中,而无症状性耳鸣可能发生在VEMP正常的耳朵中。耳鸣可能是继发性或延迟性内淋巴积液的首发症状。如果这被证明是准确的,我们应该预计这些患者会逐渐出现其他内淋巴水肿症状,如SNHL和临床前庭功能障碍。
