Idiopathic sudden sensorineural hearing loss

Amaç: Bu çalışmanın amacı idiopatic ani sensorinöral işitme kayıplı hastalarımızı sunmak ve bu hastaların odyogram şekillerini, iyileşme oranlarını değerlendirmektir. Metot: 2004-2006 yılları arasında idiopatic ani sensorinöral işitme kaybı tanısı alan hastalar çalışmaya alındı. Bütün hastalara rutin odyolojik değerlendirmeler yapıldı. İlk başvurudaki odyogram şekilleri (1) düz odyogram, (2) yüksek frekanslara doğru eğimli odyogram ve (3) alçak frekanslara doğru eğimli odyogram olmak üzere sınıflandırıldı. İşitmedeki düzelmeyi değerlendirmek için tedavi öncesi ve sonrasında saptanan saf ses eşikleri ve ayırdetme puanları arasındaki farklılıklar hesaplandı. Sonuçlar: Bu çalışmada bütün gruplarda iyileşme oranı yüksek bulundu. Gruplar arasında iyileşme oranı açısından farklılık görülmedi. İyileşme ile tedaviye erken başlama olgusu arasında bir ilişki saptanmadı. İstatistiksel analizler için gruplardaki hasta sayıları yetersiz bulundu. Tartışma: İdiyopatik ani sensorinöral işitme kaybına ilişkin özellikleri ve etken faktörleri ortaya koyabilmek için, çalışmanın sürdürülmesine karar verildi.

İdiopatik ani sensorinöral işitme kaybı

Objective: The purpose of this study is to present our patients with ISSHL and to assess the shape of the audiogram and the recovery incidence of the patients. Methods: 28 patients who were referred to our clinic under diagnosis as idiopathic sudden sensorineural hearing loss during two years (between 2004 - 2006) were included in the study. Routine audiological evaluation was performed to all patients. Shape of initial audiograms was classified in 3 groups: (1) flat audiogram; (2) upsloping audiogram; (3) downsloping audiogram. Differences in PTA and WDS between pre and post-treatment were calculated to assess the recovery of hearing. Results: In this study, recovery rate was high in each of the three groups. There was no difference in the recovery rate between the groups. There was no relation between recovery and early referral to therapy. The groups were very small for statistical analysis. Conclusion: It is necessary to enlarge the study group to compare the effects of the factors on idiophatic sudden sensorineural hearing loss.
