When nerve deafness results in complete hearing loss depends on the specific condition of the patient and cannot be generalized. Nerve deafness is a common otologic disorder caused by structural or functional disorders of the auditory system in sound conduction, perception, and analysis of integrated areas. There are various types of clinical manifestations, such as age-related deafness, congenital deafness, sudden deafness, noise-related deafness, and deafness due to systemic diseases. Usually, within 72 hours of sudden onset of neurological deafness is the golden period for treatment, during which most hearing loss can be avoided if patients take timely scientific and effective medication. Since neurological damage is irreversible, treatment of neurological deafness that is more than six months old is less effective. And with age, hearing gradually declines, and some patients may lose their hearing. In addition, patients should pay attention to low salt, sugar and fat intake during the onset of the disease, and ensure sufficient rest to promote blood circulation, so as to reduce the damage caused by neurological deafness to the body.
