In 2015, the World Health Organization announced that 360 million people worldwide were affected by hearing loss, accounting for 5% of the world's population, including 30.28 million adults and 32 million children. The results of the sixth national census in 2010 showed that the total number of children aged 0 to 14 in my country exceeded 220 million. In addition, based on birth rates and morbidity rates, approximately 16,000 to 48,000 newborns have hearing problems every year.

What causes congenital hearing loss in children?

Hearing loss in children generally refers to children aged 0-14 who have difficulty hearing in both ears due to various reasons, and cannot or cannot hear environmental sounds and voices clearly. According to the severity, it can be divided into mild, moderate, severe and extremely severe. In mild cases, it is difficult to hear soft speech, in moderate cases, it is also difficult to communicate with ordinary sounds, in severe cases, children need to speak loudly to hear speech fragments, and in extremely severe cases, children have the most serious problems and need to shout loudly close to the ear. Only fragments of language can be heard.

Congenital causes: The child is born with it, mostly due to genetic factors, or the mother is infected by rubella, measles, herpes and other viruses during pregnancy, or The use of aminoglycoside antibiotics (streptomycin, gentamicin, kanamycin, etc.) or the mother's alcoholism or drug abuse during pregnancy can damage the fetus's inner ear and auditory nerve. In addition, the mother's fourth to twentieth week of pregnancy At eight weeks, the fetal nervous system is developing. Sudden noise or incorrect use of prenatal music (more than 60 decibels) can affect the development of the fetal auditory nerve.

What should you do if you find that your child has hearing loss?

There are currently two main methods for children with hearing loss, one is to wear Hearing Aids, and the other is to surgically implant cochlear implants. Wearing a hearing aid means that the hearing aid amplifies external sounds and uses the child's residual hearing to listen. Cochlear implants use cochlear implants to replace the original cochlear function to reconstruct hearing when children have no residual hearing. The biggest difference between the two is that hearing aids are hearing compensation, and cochlear implants are hearing reconstruction. Generally speaking, those who have residual hearing choose hearing aids for hearing compensation, and those with extremely severe hearing loss who have poor or ineffective hearing aids choose cochlear implants for hearing reconstruction.

Because cochlear implant surgery requires a series of preoperative evaluations and medical examinations, it is relatively complex.It is complicated, and parents are advised to go to the hospital for detailed consultation.

In addition, children are in a period of rapid growth and development, especially the preschool stage, which is a critical period for speech development. Due to hearing impairment, they cannot receive enough speech stimulation information and cannot master pronunciation skills. It will lead to unclear pronunciation, affect language acquisition, and even become deaf-mute. Parents should pay attention to their children's reactions to sounds and conduct hearing screenings every year.
