However, when a detailed examination is done, there is no significant hearing loss. If it is determined that there is a hearing loss on one side of the ear, it is best to go to the ENT department of the hospital to have electrical audiometry and acoustic conduction resistance done to clarify the diagnosis. If the hearing loss is caused within a short period of time, you can also go to the hospital for detailed treatment, such as ginkgo biloba extract, methylcobalamin injection, vincristine capsule, etc. If the effect is not good after treatment, you can also consider hearing aids.
