At present, there are about 30 million people with childhood deafness in the world, and in China it is almost 80 to 1 million. The child carries the hopes of the whole family, and every move of the child affects the hearts of the whole family. However, the cruelty of the disease and childhood deafness will affect the child's physical and mental health.
Is there a specific cause of deafness in children?
The common causes of deafness in children are as follows:
1. Drugs: Some drugs are ototoxic, such as streptomycin, kanamycin, gentamicin, polymyxin, and diuretic acid and antimalarial drug quinoline. The reason why ototoxic drugs cause deafness is not yet clear. It may affect the metabolism of inner ear cells, making them unable to fully utilize various necessary nutrients, leading to the degradation of auditory cell function and causing neurological deafness.
2. Heredity: Whether deafness occurs after using the above drugs is not only related to the dose and course of treatment, but also to individual susceptibility. Susceptible children only need to use a small amount of drugs, and sometimes only one topical application can cause severe ototoxicity. This susceptibility is related to genetics. If someone in the family has already suffered from drug-induced deafness, the use of such drugs in children must be prohibited.
3. Noise: Deafness caused by noise cannot be ignored, mainly due to firecrackers set off during festivals. The loud sound produced by certain types of firecrackers at the moment of explosion can perforate the eardrum, break the drum chain, and cause conductive deafness.4. Systemic diseases: such as mumps, influenza, typhoid, meningitis, diabetes and some autoimmune diseases; diseases that occur locally in the ear include acute otitis media and chronic catarrhal otitis media , foreign bodies in the external auditory canal, etc. When the above diseases occur, the possibility of hearing damage should be taken into consideration and hearing monitoring should be carried out in time.
When talking about deafness in children, let’s take a look at this picture first. This is a picture of the auditory conduction pathway. After the auricle collects sound, it passes through the vibration of the sound wave in the external auditory canal. It vibrates the eardrum and the three small bones in the middle ear, transmitting the sound to the cochlea in the inner ear. After the hair cells of the cochlea receive sound stimulation, they are transmitted to the hearing center through the cochlear nerve.
What does deafness in children mean? It means some organic lesions on the auditory conduction pathway, or functional (caused by lesions), generally Generally speaking, deafness in children is more common due to organic (lesions), which means that lesions at any part of this conduction pathway can lead to varying degrees of hearing loss. We collectively call it deafness, which occurs in children. We call the child deaf.
