What's wrong with the child's hearing loss?

Children's hearing development is an issue that many parents are very concerned about. Many adults are very worried about their children's hearing loss. Clinically, if a child is deaf, it is likely caused by hearing impairment. The reasons why children cannot hear are quite complicated and many factors need to be considered. So what exactly is going on when children cannot hear?

1. Syndromic deafness:

Common syndromic deafness in clinical practice includes large vestibular aqueduct syndrome, Usher syndrome, Alström syndrome, and Waardenburg syndrome mentioned in the previous case. These children often show a group of clinical manifestations in different organs of the body, including deafness. Taking Waardenburg syndrome as an example, Waardenburg syndrome (WS) is one of the common clinical diseases that cause syndromic deafness. It is inherited in an autosomal dominant manner. At least 2% of congenital deafness is caused by Waardenburg syndrome.

2. Drug poisoning:

Some studies have shown that ototoxic drugs have become one of the main causes of hearing loss in children. Deafness-causing drugs mainly include aminoglycosides, salicylates, anti-tumor drugs, and alcohol. Common ones include streptomycin, dihydrostreptomycin, neomycin, kanamycin, gentamicin, vancomycin, puromycin, tobramycin, paromomycin, polymyxin B, quinine, aspirin, etc. In addition, some anti-tumor drugs and diuretics can also damage the auditory nerve and cause hearing impairment.

3. The physiological structure of children's ears causes deafness:

When young children have a cold, are sucking milk in a supine position, or are nauseous or vomiting, they often develop bacterial infection in the middle ear cavity and develop acute suppurative otitis media. As the pus in the middle ear cavity continues to increase, the child will cry loudly due to the worsening ear pain. The pressure caused by the increased pus in the middle ear cavity can also cause perforation and rupture of the eardrum. If medical treatment is not sought promptly or the treatment is not thorough, it will cause chronic suppurative otitis media, resulting in continuous damage to the eardrum. As the perforation gets bigger, the impact on hearing will become more serious. 1. Syndromic deafness:
