Is the time from the onset to the treatment a prognostic indicator for hearing recovery in idiopathic sudden sensorineural hearing loss?

Abstract

Objectives: This study aims to investigate whether the time from the onset of symptoms to the start of treatment is a prognostic indicator in patients with idiopathic sudden sensorineural hearing loss ISSNHL . Patients and Methods: In this study, 96 patients 58 males, 38 females; mean age 37.8±2.5 years; range 16 to 67 years who were diagnosed with ISSNHL in our clinic between January 1992 and April 2010 were retrospectively analyzed. All patients were treated with dextran 40 rheomacrodex , pentoxifyllin, vitamin B complex and vitamin C regimen over 10 days with hospitalization and bed rest. The patients were tested by pure-tone audiometry. Audiograms were obtained on alternate days and at the end of the treatment. Results: There was a complete recovery in 45 60% of 75 patients whose treatment was started in the first seven days, while a partial recovery was observed in 17 22.66% and no recovery was observed in 13 17.33% . There was a complete recovery in two 9.52% of 21 patients whose treatment was started after the eighth day, while a partial recovery was observed in seven 33.33% and no recovery was observed in 12 57.14% . Conclusion: Our study results suggest that treatment outcomes are better in the patients presenting to hospital at an early stage of loss of hearing.

Abstract

Amaç: Bu çalışmada idiyopatik ani sensörinöral işitme kaybı İASNİK olan hastalarda semptomların başlangıcından tedaviye başlama zamanına kadar geçen sürenin prognostik bir belirteç olup olmadığı araştırıldı.Hastalar ve Yöntemler: Bu çalışmada Ocak 1992 - Nisan 2010 tarihleri arasında kliniğimizde İASNİK tanısı konmuş 96 hasta 58 erkek, 38 kadın; ort. yaş 37.8±2.5 yıl; dağılım 16-67 yıl retrospektif olarak değerlendirildi. Hastaların tümü 10 gün süreyle hastane yatışı ve yatak istirahati ile dekstran 40 rheomacrodex , pentoksifilin, B vitamin kompleksi ve C vitamin rejimi ile tedavi edildi. Hastalar saf ton odyometrisi ile test edildi. Odyogramlar farklı günlerde ve tedavi sonunda elde edildi.Bulgular: Tedavilerine ilk yedi gün içerisinde başlanan 75 hastanın 45’inde %60 tam iyileşme, 17’sinde %22.66 kısmi iyileşme görüldü, 13’ünde %17.33 ise herhangi bir iyileşme gözlenmedi. Tedavilerine sekizinci günden sonra başlanan 21 hastanın ikisinde %9.52 tam iyileşme görülürken, yedisinde %33.33 kısmi iyileşme görüldü, 12 hastada %57.14 ise herhangi bir iyileşme gözlenmedi.Sonuç: Çalışma sonuçlarımız, işitme kaybının erken döneminde hastaneye başvuran hastalarda tedavi sonucunun daha iyi olduğunu göstermektedir
