%X <B>OBJECTIVE: </B>The purpose of the present study is to find the functions of vestibular reflexes in individuals' with normal hearing and tinnitus, to identify vestibular dysfunctions earlier, and helps with the management of the same.<BR><B>METHODS: </B>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.<BR><B>RESULTS: </B>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.<BR><B>CONCLUSIONS: </B>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.
