DÝABETLÝ HASTALARDA KLÝNÝK VE SUBKLÝNÝK ÝÞÝTME BOZUKLUKLARININ ABR ÝLE ÝNCELENMESÝ

Bu çalýþmada 40 diabetik hastaya ABR uygulanarak iþitme yollarýnýn fonksiyonel bütünlüðü deðerlendirildi. Diabetli hastalarda V.dalga mutlak latansýnda ve I-V interpeak latansýnda anlamlý uzama saptandý. Diabet komplikasyonlarýnýn varlýðýna baðlý olarak Auditory Brainstem Response (ABR) dalga latanslarýndaki uzamanýn arttýðý görüldü. Komplikasyonlu grup Tip I ve Tip II olarak ayrýldýðý zaman, Tip II diabetiklerde diðer gruplara göre anlamlý bir V. dalga mutlak latans uzamasý tespit edildi. Tedavi þekline ve diabetin süresine göre ABR latanslarýnda anlamlý uzamalar tespit edilmedi.

THE EXAMINATION OF CLINICAL AND SUBCLINICAL HEARING DEFECTS WITH ABR IN DIABETIC PATIENTS

In this study we have utilized ABR audiometry to evaluate the functional integrity of hearing pathways in 40 diabetic patients. We have found significant increase in the absolute lateney of wave V and in the interpeak latency of I-V in diabetics. Increased ABR wave latencies have been found to be more pronounced in cases with diabetic complications. Of those cases with complications, separated into groups of Type I and Type II diabetics had a significant increase in wave V absolute latency. No significant increases in latencies have been found in association with therapeutic regimen or duration of the disease.
