Introduction: Cochleovestibular disorders in patients with diabetes is not well known as compared to other complications. The aim of this study was to evaluate the epidemiological, clinical and paraclinical characteristics of cochleovestibular dysfunction in diabetes.
Materials and Methods: This is a retrospective study of 100 diabetic patients. The patients had a clinical otological and vestibular examination as well as a tonal audiometry and a video nystagmography.
Results: The mean age of our patients was 50.97 years with extremes ranging from 17 to 82 years. A female predominance was noted with a sex ratio of 0.66. The mean duration of diabetes was 10 years with extremes ranging from 5 to 27 years. The diabetes was type 1 in 22 cases and type 2 in 78 cases. Degenerative complications were noted in 20% of cases. These included diabetic retinopathy alone in 7% of cases, diabetic neuropathy in 6% of cases and both complications in 7% of cases. Deafness was noted in 32 cases (32%). It was a sensorineural hearing loss in all cases, more important in the medium to high frequencies. The hearing impairment was more severe in type 1 diabetes. Vestibular involvement (peripheral and/or central) was present in 24 cases (31.5%). An analytical study analyzing epidemiological characteristics, metabolic control, and the presence of degenerative complications did not find statistically predictive factors for cochleovestibular involvement.
Conclusion: In our study, we did not find any predictive factor for vestibular impairment in diabetics. However, this is only preliminary data, because our study did not include non-diabetic controls.
