YENİDOĞANDA İŞİTMENİN GELİŞİMİ VE İŞİTME TARAMA TESTLERİ

Atmosferde meydana gelen ses dalgalarının kulağımız tarafından toplanmasından beyindeki merkezlerde karakter ve anlam olarak algılanmasına kadar olan süreç işitme olarakadlandırılır. İşitme kaybı, 1/1000 ile 3/1000 arasında değişen oranla yenidoğan bebeklerde en sık görülen konjenital anomalilerden biridir ve yenidoğan yoğun bakım ünitesinde(YDYBÜ) yatış bu riski arttırır. Bu nedenle YDYBÜde izlenen bebekler işitme taraması içinhedef kitlelerden biridir. Yenidoğan döneminde kabul edilen iki işitme tarama yöntemivardır: Uyarılmış Otoakustik Emisyonlar (EOAEs) ve İşitsel Beyinsapı Yanıtı (ABR).

Development of Newborn Hearing and Hearing Screening

Hearing is the process of the collection of sound waves in the atmosphere by the ear, resulting in the perception of a certain character and meaning in the related centers in thebrain. Hearing loss is one of the most frequently seen congenital anomalies in infants,with an incidence varying between 1/1000 to 3/1000 of healthy newborns and infantsadmitted to the Neonatal Intensive Care Unit (NICU) have an additional risk of hearingloss. Infants at NICU form an important target group for hearing screening. Of the hea- ring screening methods of the newborn, two are widely accepted: Evoked AutoacusticEmission (EOAEs) and Auditory Brainstem Response (ABR).
