What are the acquired factors of hearing impairment?

1. Children with trauma should be tested for hearing loss after trauma. 2. Infection Deafness caused by infection is mainly mumps, which is common between 2 and 10 years old.The virus “prefers” to invade the auditory nerve. Deafness often occurs 2 to 3 weeks before, during or after the onset. It is often manifested as unilateral severe sensorineural deafness or even total deafness, but most of them are deaf on one side.Diao Mingfang, Department of Otolaryngology, Naval General Hospital 3. Ototoxic drugs are also common factors that cause deafness.There are many deaf children who are deaf after taking medicine. Many of them have the same experience: they have had injections, infusions or some drugs before deafness.The use of gentamicin, streptomycin, kanamycin, neomycin, etc. should be avoided as much as possible. 4. Noisy children who are exposed to the roar of machines, firecrackers, loud noises in the disco, various noises, etc. for a long time will cause damage to the hair cells of the inner ear, cause rapid hearing loss, and cause noise-induced deafness.Parents should pay attention to the child’s speech and behavior. If the child is found to be unresponsive, introverted, not talkative, and others must speak loudly to hear, they must go to the hospital for a hearing screening. If hearing impairment is found, they should be treated as soon as possible. Only better results can be obtained. (Author: Diao Mingfang)
