瞬态诱发耳声发射在新生儿听力筛查中的应用

Application of Neonatal Hearing Screening with Transiently Evoked Otoacoustic Emission

耳声发射是一种产生于耳蜗,经听骨链及鼓膜传导释放入外耳道的音频能量。以短暂声刺激诱发产生的耳声发射称为瞬态诱发耳声发射。该检查方法客观、敏感、无创,在新生儿的听力筛查中具有较大的应用价值。现就瞬态耳声发射及其在新生儿听力筛查中的应用进行综述。

Otoacoustic emissions （OAEs） are sounds that originate in the cochlea and propagate through the middle ear and into the external ear canal. Transiently evoked otoacoustic emission （TEOAE） is a type of OAE which is evoked by transient stimuli, such as click or toneburst. The potential advantages of TEOAEs of neonatal hearing screening are that： Ononinvasive and do not require the attachment of electrodes; and O specific to the peripheral auditory system, in particular outer hair cells. This review provides a brief introduction to TEOAEs and their applications in neonatal hearing screening.
