If a patient has moderate hearing loss in one ear, the effect is not so great, because the other ear can compensate for the hearing loss, but if both ears have moderate hearing loss, the effect is relatively large, and normal communication may be limited. Therefore, if hearing impairment occurs, it must be actively treated. It is recommended to go to the hospital to clarify the degree and type of hearing loss, and to consider hospitalization for infusion therapy. The two drugs combined can effectively treat hearing loss, improve circulation and dilate blood vessels, nourish the nerve symptomatically, and at the same time must be reasonable rest.
