目的探讨高危新生儿未通过初次筛查是否与外耳道栓塞、中耳病变有关。方法对166例高危新生儿在出生后进行畸变产物耳声发射(DPOAE)检查,未通过的新生儿立即行声阻抗测试。结果初查时有38例新生儿未通过,声阻抗测得鼓室曲线均为A型。结论本研究显示新生儿未通过初次筛查与外耳道栓塞、中耳病变无明显联系。 Objective To investigate whether the high-risk neonates failed to pass the initial screening and whether they were related to ear canal embolization or middle ear lesion. Methods One hundred and sixty-six high-risk neonates were examined for distortion product otoacoustic emissions (DPOAE) after birth. Non-passing neonates immediately underwent acoustic impedance tests. Results 38 cases of newborns did not pass the initial examination, the acoustic impedance measured tympanogram are A type. Conclusion This study shows no significant correlation between newborn infants failed to pass initial screening and external auditory canal embolization.
