Abstract

Objectives: To determine the speech perception levels of cochlear implant patients and to evaluate the possible effects of implant type, duration of deafness, and bacterial meningitis on the patients' hear-ing performance. Patients and Methods: A three-section test battery on speech perception was administered to 21 cochlear implant patients (12 males, 9 females; mean age 25 years; range 9 to 40 years). The patients' performance was assessed with respect to single- or multi-channel implant design, duration of hearing loss, and etiologic factors of hearing loss. Results: The overall mean success score was 74.6 (range 49-100). No significant difference was found between patients using single- or multi-channel implants. The mean score of 12 patients whose duration of hearing loss was below the average (8.2 years) was significantly higher than those of nine patients with a longer history of hearing loss (85.7 versus 59.6, p=0.001). Patients with meningitis-associated hearing loss exhibited a significantly lower performance than those presenting with other etiologic factors (61.9 versus 84.1, p=0.001). Conclusion: Early diagnosis and rehabilitation are essential to achieve better performance following cochlear implantation.

Özet

Amaç: Koklear implant uygulanan hastalarda konuşmayı algılama düzeylerini belirlemek ve işitme kaybı süresi, implant tipi ve bakteriyel menenjitin hastanın işitme performansı üzerindeki etkisini değerlendirmek. Hastalar ve Yöntemler: Koklear implantasyon uygulanan 21 hastaya (12 erkek, 9 kadın; ort. yaş 25; dağılım 9-40) üç bölümlük işitsel anlama testi uygulandı. Hastaların testte gösterdikleri başarı, tek- veya çok-kanallı implant kullanımı, işitme kaybı süresi, işitme kaybının etyolojik nedenleri açısından değerlendirildi. Bulgular: Ortalama başarı puanı 74.6 (dağılım 49-100) düzeyinde bulundu. Tek-kanallı ve çok-kanallı implant kullanan olgular arasında performans açısından istatistiksel olarak anlamlı farklılık görülmedi. İşitme kaybı süresi, ortalama sürenin (8.2 yıl) altında olan 12 olguda performans testindeki başarı ortalaması 85.7; üzerindeki dokuz olguda ise 59.6 bulundu (p=0.001). Postmenenjitik işitme kaybı olan dokuz olgunun testteki başarısı (61.9) diğer etyolojilere sahip olguların (84.1) başarısından anlamlı derecede düşüktü (p= 0.001). Sonuç: Koklear implantlı hastalarda daha iyi işitme performansı için işitme kaybının erken tanısı ve olguların rehabilitasyonu önem taşımaktadır.
