İnvitro kazanç analizleriyle işitme cihazı seçimi

Amaç: Bu çalışmada ilk kez işitme cihazı önerilen sensörinöral işitme kayıplı hastalarda invitro kazanç ölçümleri yapılarak optimum kazanç sağlayan işitme cihazlarının belirlenmesi amaçlandı. Gereç ve Yöntem: Ellisekiz hastada işitme cihazı invitro kazanç analizleri yapıldı. Bulgular: Hem subjektif hem de objektif yöntemlerle seçilen işitme cihazlarıyla yüksek performans elde edildi. Takip dönemi boyunca cihazından şikayet eden hasta olmadı. Sonuç: İþitme cihazı invitro kazanç ölçümü pratik ve objektif bir değerlendirme yöntemidir. Bu ölçümler yardımı ile seçilen işitme cihazlarından beklenen performans alınabilmektedir.

Hearing aid selection by insertion gain measurements

Objectives: The purpose of this study was to prescribe the first hearing aids with highest performance for the patients who have sensoryneural hearing loss. Materials and Methods: Insertion gain measurements were performed in 58 patients. Results: High performance was noted for the hearing aids that were selected by subjective and objective methods. There were no patients suffering from hearing aids, during the follow-up. Conclusion: Insertion gain measurements are the practical and objective methods of hearing aids` evaluation. The expected performance would be obtained from the hearing aids that are prescribed by these measurements.
