Abstract
Data of 32 diabetic patients diagnosed with diabetes mellitus with and without complications, were collected. The results of the audio-vestibular tests were analyzed.
There was significant correlation between the duration of diabetes and occurrence of diabetic complications (cochleo-vestibular nerve neuropathy). Diabetic patients with long duration of diabetes had diabetic complications more than young age and recent diabetics. Also, there was no significant difference between treatment of diabetes and occurrence of diabetic complications.
There was significant correlation between the diabetic complications and the degree of hearing loss. The diabetic patients with complications had more hearing loss especially at high frequency than diabetic patients without complications. And so in speech discrimination score which is affected in diabetic patients with complications. Although the speech discrimination score was excellent at both diabetic patients with and without complications ,it started to be affected with occurrence of diabetic complications.
ABR was abnormal in only diabetic patients with complicated diabetes reflecting sensitivity of 100% in detecting diabetic neuropathy in diabetic patients with diabetes complications especially diabetic patients with nephropathy.
DPOAE and diabetic complications showed significant correlation. in diabetic patients without complications had partial pass DPOAE results .Moreover diabetic patients with complications had fail DPOAE results
All grouped diabetic patients without complications had intact and normal cVEMP response. Furthermore, No significant difference was found between diabetic patients without complications and normal persons as regards P1-N1 amplitude, P1 latency, N1 latency. On the other hand ,All grouped diabetic patients with diabetic complications had only abnormal reduced P1-N1 amplitude.
In VNG, All grouped diabetic patients with and without diabetic complications had symmetrical caloric response. Furthermore, No significant correlation between caloric test response and diabetic complications.
