“…The ABR wave amplitudes and latency differences between waves may provide information about pathologies in central auditory pathways. [27] In our study, there was no difference in the amplitude of ABR waves and latency between waves in keratoconus grup compared to control group and no abnormality was detected in waves. This shows that there is no effect on cochlear and retrocochlear hearing pathways in patients with keratoconus.…”

Bu çalışmada keratokonuslu hastaların işitme durumu değerlendirildi. Hastalar ve Yöntemler: Kasım 2018-Nisan 2019 tarihleri arasında gerçekleştirilen bu olgu-kontrol çalışmasına 23'ü (12 erkek, 11 kadın; ort. yaş 31.6±7.8 yıl; dağılım, 20-46 yıl) keratokonus tanısı almışken 33'ünde (13 erkek, 20 kadın; ort yaş 30.8±4.4 yıl; dağılım, 18-49 yıl) hiçbir göz hastalığı olmayan (kontrol grubu) 56 denek (25 erkek, 31 kadın; ort. yaş 31.2±7.5 yıl; dağılım, 18-49 yıl) dahil edildi. Tüm hastalarda saf ses odyometrisi, immitansmetrik ölçümler ve işitsel beyin sapı yanıtı testleri uygulandı. Grupların odyolojik test sonuçları karşılaştırıldı. Bulgular: Grupların yaş ve cinsiyet dağılımı arasında istatistiksel olarak anlamlı farklılık yoktu (sırasıyla, p=0.336 ve p=0.125). Kontrol grubunda 2000 Hz'deki akustik refleks değeri keratokonus grubundan anlamlı şekilde yüksekti (p=0.030; p<0.05). Grupların diğer akustik refleks ölçümlerinde anlamlı farklılık yoktu (tüm p değerleri >0.05). İşitsel beyin sapı yanıtı testi ölçümlerinde I-III, III-V ve I-V dalga gecikmeleri arasında istatistiksel olarak anlamlı farklılık yoktu (tüm p değerleri >0.05). Sonuç: Bu çalışmanın sonuçlarına göre, keratokonuslu hastalarda işitme kaybı beklenmemektedir. Dolayısıyla, bu hastalarda rutin işitme muayenesine gerek olmadığına inanıyoruz. Daha büyük örneklem boyutları olan, uzun süreli takip çalışmaları gereklidir.

“…By considering the maximum output limit of the ABR device (around 100 dB nHL) and the maximum hearing levels of hearing-impaired participants (around 70 dB HL), the stimulation level was therefore set at 30 dB SL. Previous speech-ABR studies involving hearing-impaired participants used intensity levels between 80-95 dB sound pressure level (SPL) Abd El-Ghaffar [65], Anderson [35], Leite [36], Koravand [15]. Regarding the intensity level for speech-ABR recording, there is a concern whether the stimulus level should be presented in dB SPL or in dB SL when testing hearing-impaired individuals.…”

Speech-evoked auditory brainstem response (speech-ABR) provides an objective documentation of temporal and spectral encoding of speech cues in the brainstem region. As such, the influence of peripheral hearing loss on speech-ABR has been studied but the current literature is limited. The aim of the present study was to compare speech-ABR findings between children with moderate-to-severe SNHL and their agematched normal peers. In this case control study, 17 hearing-impaired (HI) children (mean age = 7.1 ± 1.8 years) and 15 typically developing (TD) children (mean age = 6.1 ± 1.6 years) were enrolled. All HI children had bilateral moderately severe sensorineural hearing loss. The speech-ABR was recorded from HI and TD children to 40-ms speech syllable /da/ presented repetitively at 30 dB sensation level (SL). Statistically longer latencies were found in HI children than in TD children for onset peaks (V and A) and transition portion (peak C) (p < 0.05) with very large effect sizes (d = 1.16 -6.10). In contrast, the sustained components (peaks D, E and F) and offset portion (peak O) of speech-ABR were unaffected by hearing loss (p > 0.05). For speech-ABR composite onset measures, TD children revealed larger VA inter-peak amplitudes (d = 0.87) and steeper VA slopes (d = 1.36) compared to HI children (p < 0.05). Children with moderately severe sensorineural hearing loss had abnormal encoding of speech sounds within the brainstem region. Based on the study outcomes, the usefulness of speech-ABR can be expanded by studying the speech encoding ability in multi-handicapped children).

Speech-evoked auditory brainstem response with ipsilateral noise in adults with unilateral hearing loss

Abstract: In monaural processing, pitch representation (F0 amplitude) and cross-phaseogram were the main affected domains. Speech phonemes of transient origin can be confused in subjects with UHL.
