Children with cerebral palsy (brain injury) combined with hearing impairment should be diagnosed and diagnosed early within 3 months of age and treated in a timely manner. If the optimal time for treatment is missed, the hearing impairment will lead to language development disorders, and ultimately lead to deafness and disability, which will seriously affect the quality of life of the affected children. Because children are young and uncooperative in examinations, it is difficult to detect hearing disorders at an early stage under general observation, and the timing of treatment may be missed. Brainstem auditory evoked potentials (ABR) is a sensitive test for early detection of hearing impairment in children with cerebral palsy (brain injury), which can provide a basis for research on the pathogenesis and pathophysiology of hearing impairment. Clinically, ABR is performed as early as possible in children with hearing impairment, usually at two months. Cerebral evoked potential examination is simple and easy to carry out, and has certain value for early diagnosis, observation of therapeutic effect and judgment of prognosis of children with hearing impairment. Acupuncture point plus locus medication injection for the treatment of hearing impairment has obvious efficacy and high cure rate. Acupuncture point injection can stimulate acupoints, dredge meridians and enhance the efficacy of drugs. Vitamin B1 has the role of repairing the central nervous system, vitamin B12 is one of the indispensable substances for nerve myelination, and rat nerve growth factor can promote the repair and compensation of nerve damage. the joint application can make the early damaged nerve cells to be repaired in a timely manner, regeneration of the synaptic axis, functional compensation, and the myelination of the nerve fibers, the synaptic structure and the network function of the growth and development of the nerve fibers. the ABR test doesn’t need to be reviewed every The ABR test does not need to be rechecked every course of treatment, but usually once in 2 courses of treatment. For children with severe or very severe hearing impairment, in addition to ABR test, they need to undergo temporal bone CT and otoacoustic emission test, TORCH test, and deafness gene test. If they are infected with CMV, they need to undergo sufficient courses of antiviral treatment; if they have organic lesions or carry disease-causing genes, the treatment is generally ineffective, and they need to wear hearing aids or even cochlear implants.
