Universal screening for newborn hearing: refers to the use of objective physiological methods to conduct hearing screening tests on all newborns born to live births.
Target population screening: refers to the use of objective physiological methods to conduct hearing screening tests on newborns with high risk factors for hearing loss.
Targeted hearing loss: congenital, permanent bilateral or unilateral, sensorineural, conductive or mixed hearing loss, frequency domain(500,1000,2000,4000Hz)Hearing loss is on average greater than30dB.
1-3-6Month mode: all babies should be born1Hearing screening within a month; all infants who fail screening must be at the latest3Receive a comprehensive hearing assessment within a month; all babies diagnosed with permanent hearing loss should receive intervention as soon as possible after diagnosis, no later than6Month age.
Hearing screening technology process:
1? History asked, paying special attention to the history of hearing loss.
2? Physical examination, otological examination, comprehensive examination of various systems throughout the body;
3? Laboratory inspection; 4
4? Imaging examination, mainly humerusCTAndMRIInspection; 5
5? Audiology assessment:ABRDiagnosticOAE, 1000HzAcoustic impedance test of the probe sound,40 HzAuditory event-related potential,ASSRWait,6Infants with more than one month can perform pediatric behavioral audiometry.
If ourBaby hearing screeningIf there are problems after coming out, it is necessary to intervene in time. The main means of early intervention of infant hearing loss: follow-up, hearing aid fitting, cochlear implant, bone anchored hearing aid (BAHA) and application of vibration bridges, drug treatment, etc.
