目的 研究瞬态声诱发耳声发射在新生儿听力筛查中的应用价值。 方法 112 3例新生儿生后 3d接受瞬态声诱发耳声发射检查 ,未通过者于出生 6周左右接受再次检查 ,出生 12周左右对再次检查未通过者进行脑干诱发电位检查。 结果 112 3例新生儿中 ,10 5 1例通过生后 3d的瞬态声诱发耳声发射初筛 ,通过率93 5 9% ;初筛未通过者 39例于出生 6周后进行复查 ,其中 2 6例通过 ;复查未通过 13例 ,出生后 12周再次接受瞬态声诱发耳声发射检查 ,其中 9例通过 ,未通过 4例经脑干听觉诱发电位检测 ,确诊为先天性耳聋。 结论 瞬态声诱发耳声发射检查速度快 ,无创伤 ,结果客观 ,可早期发现听力障碍儿 ,为先天性聋儿的早期干预奠定了基础。
Objective To investigate the value of transient acoustic evoked otoacoustic emissions in neonatal hearing screening. Methods One hundred and thirteen newborn children underwent transient acoustic evoked otoacoustic emission examination after birth. Those who failed to pass the test were reexamined at 6 weeks of age and brainstem evoked potentials were examined at 12 weeks after birth. Results 1123 newborns, 105 cases through the first three days after birth transient acoustic evoked otoacoustic emission screening, the passing rate of 93 5 9%; 39 cases of failed initial screening of 6 weeks after birth were reviewed, of which 26 cases passed; review failed 13 cases, 12 weeks after birth again underwent transient acoustic evoked otoacoustic emission examination, of which 9 cases passed, 4 cases did not pass through the brainstem auditory evoked potentials detected diagnosed as congenital deafness. Conclusion Transient acoustic evoked otoacoustic emission examination is fast and noninvasive, with objective results and early detection of hearing impaired children, which lays the foundation for the early intervention of congenital deaf children.
