Deafness caused by injections for childhood colds is generally difficult to cure. Aminoglycoside antibiotics such as neomycin may be used for childhood colds, and the main adverse effect of such drugs is ototoxicity, which damages the auditory nerve, which mediates the transmission of sound, and the damage to the nerve is often irreversible, with the inability of sound to reach the auditory center leading to deafness. The ototoxicity of aminoglycosides is directly related to their higher drug concentration in the inner ear lymphatic fluid, causing enzyme dysfunction on the cell membrane, resulting in hair cell damage, so that the positive endolymphatic potential can not be maintained, resulting in hearing impairment. If deafness caused by injections as a child is an inconvenience to your life, go to the hospital and ask if your hearing can be restored by wearing a hearing aid.
