Tone-Burst ve Klik Uyarılı İşitsel Beyin Sapı Yanıtları ile İşitsel Uyarılmış Durgun Durum Yanıtları Sonuçlarının Karşılaştırılması

Amaç: Bu çalışmada, ileri-çok ileri derecede sensörinöral işitme kaybı olan hastalarda, tone-burst ve klik İşitsel Beyin Sapı (ABR) ile İşitsel Uyarılmış Durgun Durum (ASSR) sonuçlarını karşılaştırdık.Gereç ve Yöntemler: Yaşları 2 ay ile 53 yıl arasında değişen, ileri-çok ileri derecede sensörinöral işitme kaybı olan, 30 kişilik hasta grubunun toplam 60 kulağı çalışmaya alındı. Hastalara timpanogram ve akustik refleks ölçümü, otoakustik emisyon, tone-burst ABR, Klik ABR ve ASSR testleri yapıldı.Bulgular: Tone-burst ABR ve ASSR eşikleri arasında iyi bir korelasyon olduğu gözlendi. Spearman korelasyon katsayıları 500; 1000; 2000 ve 4000 Hz’ler için sırasıyla 0.612; 0.563; 0.564 ve 0.548 olarak bulundu (p<0.01). Sonuç: ASSR, frekans spesifik ölçüm yapabilen otomatik saf ses odyogram eğrisi oluşturarak işitme seviyesini gösteren, çok kısa sürede objektif sonuç verebilen bir ölçüm yöntemidir. Ayrıca, tone-burst ve klik ABR ile ASSR gibi tüm testlerin birlikte kullanılması önerilir.

A Comparison of the Results Measured by Audotory Steady State Responses and Using Frrequency-Spesific Evoked Auditory Brainstem Response

Objective: In this study, we compared the results of Auditory Brainstem Responses (tone-burst and klik ABR) and Auditory Aware Static State Responses (ASSR) in patients with sensorineural hearing loss at advanced and very advanced.Material and Methods: A total of 60 ears of a 30-patient group with sensorineural hearing loss between 2 months and 53 years of age were included in the study. Patient's tympanogram and acoustic reflex measurement, otoacoustic emission, tone-burst ABR and ASSR tests were performed.Results: There was a good correlation between tone-burst ABR and ASSR thresholds. Spearman's correlation coefficients were found 500; 1000; 2000 and 4000 Hz,; 0.612 ,0.563; 0.564 and 0.548 respectively (p <0.01). Conclusion: ASSR is a measurement method which can produce a frequency specific measurement, which gives better results at high frequencies, produces a pure sound audiogram curve shows hearing level and it is an objective measurement method which give results in a very short time. Additionaly, we recommended use combination of all tests such as tone-burst ABR and ASSR.
