Özet
Bu çalışmada idiopatik ani işitme kayıplı hastalarda vestibüler sistemin olası etkilenmesinin vestibüler uyarılmış miyojenik potansiyeller testi ile analiz edilerek işitme kaybının son durumu ve prognoz üzerindeki etkisinin değerlendirilmesi amaçlanmıştır. Çalışmamız, idiyopatik ani işitme kaybı tanısı almış 19-65 yaş arası 27 olgu (27 hasta ve 27 sağlam kulak) içermektedir ve otolojik şikayeti olmayan kontrol grubu19-52 yaş arası 30 olgudan (60 kulak) oluşmaktadır. Olguların sırası ile kulak burun boğaz muayenesi ve denge muayenesi yapıldı. Muayene sonrası olgulara pür ton odiometri, timpanometri ve vestibüler uyarılmış miyojenik potansiyeller testi uygulandı. Hasta kulaklar Siegel düzelme kriterine göre tam düzelen, parsiyel ya da hafif düzelen ve düzelmeyen olgular olarak 3 gruba ayrıldı. Çalışma grubunda hasta kulakların işitme seviyesinin son durumu ile tam düzelen olguların, parsiyel ya da hafif düzelen olguların ve düzelmeyen olguların vestibüler uyarılmış miyojenik potansiyel bulgularıyla karşılaştırıldı. Kontrol grubunu oluşturan olguları çalışmamız için normatif veri olarak kullandık. Hasta ile sağlam kulaklar arasında vestibüler uyarılmış miyojenik potensiyeller P1 latanslarında istatiksel olarak anlamlı fark vardı (p<0,05). Hasta kulaklar ile kontrol kulaklar arasında vestibüler uyarılmış miyojenik potensiyeller P1 latanslarında istatiksel olarak anlamlı fark vardı (p<0,05). Hasta kulaklar Siegel düzelme kriterine göre düzelme göstermeyen olguların tam düzelme ve parsiyel ya da hafif düzelme gösteren olgulara göre P1 latansında uzama amplitüdlerde azalma göstermiştir. Vestibüler uyarılmış miyojenik potensiyeller testi, idiyopatik ani işitme kaybı olan hastalarda pognoz süreci açısından erken tanıda prognozu belirlemede yardımcı olabileceğini düşündürmektedir.
Abstract
In this study is purposed to evaluate final state of the hearing loss and effect on prognosis which is analyzed vestibular evoked myogenic potentials test with possible effect of vestibular system in the patients of idiopathic sudden hearing loss. The study group who have diagnosed with idiopathic sudden hearing loss includes 27 cases between the ages of 19-65 (27 damaged and 27 healthy ears) and the control group who have not otologic complaint consists of 30 cases between the ages of 19-52 (60 ears) in our study. Respectively, the cases were examined ear nose and throat examination and examination of the balance. After examination, the cases were performed pure tone audiometry, tympanometry and vestibular evoked myogenic potentials test. These ears divided into 3 groups according to the criteria of Siegel's improvement; complete recovery, partial or slightly recovery and no improvement. The final state of hearing level in the study group's damaged ears were compared with vestibular evoked myogenic potentials in the cases of complete recovery group, partial or slightly recovery group and no improvement group. We used control group's cases in our study as normative data. There was statistically significant difference between healthy and damaged ears in their vestibular evoked myogenic potentials P1 latencies (p<0.05). There was statistically significant difference between damaged and control ears in their vestibular evoked myogenic potentials P1 latencies (p<0.05). According to the criteria of Siegel's improvement, the damaged ears had no improvement compared to have been shown in complete recovery and partial or slightly improvement as elongation in P1 latencies and a reduction in amplitude. We thougt that; vestibular evoked myogenic potentials test may help you to determine prognosis of early diagnosis in terms of prognosis process in the patients of idiopathic sudden hearing loss.
