Screening Two-stage screening is implemented: health care institutions, with the informed consent and informed choice of the guardians of newborns, perform primary screening from 2-5 days after birth to before discharge, and those who fail to pass the screening should be rescreened within 42 days after birth, and those who still fail should be referred to a tertiary hospital qualified to detect neonatal diseases (hearing). For key screening subjects, even if they pass the screening, they should still be combined with auditory behavior observation method, and the infant’s guardian should be informed to follow up every 6 months for 3 years, and the problems found in the follow-up should be referred to confirm the diagnosis and treatment. Diagnosis and evaluation: Instrumental evaluation: Infants who fail the retest should undergo otolaryngological examination and otoacoustic conduction resistance, otoacoustic emission, auditory brainstem evoked potential testing, behavioral audiometry and other related examinations at a tertiary hospital qualified to detect neonatal diseases (hearing) at 2-3 months of age, as well as medical and imaging examinations to make diagnosis and evaluation, usually at 6 months of age, to clarify the degree of hearing loss and the causes of The diagnosis and evaluation are usually made at 6 months of age to determine the degree of hearing loss and the site of hearing loss and the possible causes. Treatment and intervention 1. Treatment: Tertiary care hospitals with neonatal disease (hearing) testing qualifications are responsible for treating children with diagnosed hearing loss for the cause. (2) Hearing compensation or reconstruction: For children diagnosed with sensorineural deafness, tertiary care hospitals qualified to detect neonatal diseases (hearing) are responsible for the following early interventions: (1) Hearing aid selection: For children with partial hearing (mild to severe hearing impairment), appropriate hearing aids are selected according to relevant standards for hearing correction; (2) Cochlear implantation: For children with severe hearing impairment, appropriate hearing aids are selected according to relevant standards for hearing correction. (2) Cochlear implantation: For children with severe or profound cochlear hearing loss, cochlear implantation can be performed if conditions permit; (3) Hearing and language training: After hearing aids or cochlear implantation, arrange for the child to receive appropriate hearing and language rehabilitation training and home rehabilitation guidance at relevant rehabilitation institutions to promote the development of hearing and language.
