Abstract :
Aim. The aim of this study was to evaluate clinical value of audiometry and auditory brainstem responses (ABR) in type 2 diabetes mellitus (DM) patients. Methods. Fifty patients with type 2 DM (33 females, 17 males) were included in the study with 50 age- and sex- matched controls. All patients and controls underwent ear-nose-throat examination. Pure tone audiometry, high frequency audiometry and ABR were performed. Statistical analysis was performed with Fisher’s exact, χ2, and variance analysis tests. Results. ABR of diabetic patients and control group were compared. There was no significant difference between I. wave, III wave absolute latency and I-III interpeak latency, significant elongation was determined in V. wave absolute latency and III –V and interpeak latency. Conclusions. Normal I. wave absolute latency, which shows peripheric conduction time and elongated V. wave absolute latency and II-V and I-V interpeak latency, which show central conduction time, point that diabetic neuropathy affection the upper part of the brain stem more obviously. İn diabetic patients conduction velocity of auditory nerve is especially affected centrally than the peripheric.
