How to diagnose congenital deafness in children as early as possible?

       To understand whether a newborn has congenital deafness as soon as possible, newborn hearing screening is extremely important.The so-called newborn hearing screening refers to the audiology testing performed during hospitalization for every new born child.According to the results of the examination, the subjects were divided into two groups: those who passed the screening and those who failed the screening.Those who fail the screening are suspected of hearing impairment and must undergo further examination to determine whether there is genuine hearing impairment, as well as the extent and nature of hearing impairment.

       新生儿听力筛查是通过耳声发射、自动听性脑干反应和声阻抗等电生理学技术,在新生儿出生后自然睡眠或安静的状态下进行客观、快速和无创的检查。一般仅用5~10分钟就可以完成测试。新生儿在出生48小时以后,要接受初次听力筛查,未通过初筛者,在42天左右接受听力复查,42天复查仍未通过者,在3个月左右进行听力诊断性检查。确诊为听损伤的患儿应及时到医院的专科进行相应的医学干预。
