Recently, a lot of patients have been suffering from sudden deafness, and I can relate to them because I have friends who have also suffered from it. The full name of sudden deafness is sudden idiopathic sensorineural deafness (hearing loss), and it has many causes, mostly related to fatigue, stress, mood swings, cardiovascular disease, high blood lipids, diabetes, and weather changes. Some are associated with excessive telephone calls, gunfire, gun discharge, listening to Walkman, disco or concert noise stimulation. These precipitating causes may lead to spasm, embolism of the blood vessels supplying the inner ear, lesions of the inner ear membrane vagus, resulting in sudden hearing loss, possibly accompanied by tinnitus, or even vertigo. Treatment: Temporality is most critical. The nerve cells in the inner ear have a limited tolerance to ischemia and hypoxia, so the timeliness of treatment for sudden deafness is very critical. Just like a planted flower that lacks water, timely watering can still save all or part of it, while watering again after a long drought may not help. The treatment of sudden deafness is divided into the following times, after regular treatment: Within one day of sudden deafness or sudden tinnitus: most of the recovery is satisfactory. Within three days: Most recover well. Within one week: About half of the patients recover to varying degrees. Within one month: Treatment is more difficult, although nearly 1 in 5 patients improve. More than one month: treatment is quite difficult, some patients may partially improve with aggressive treatment. The above conclusions are based on my personal experience only and may differ somewhat from textbooks or the experience of other physicians. Treatment suggestions: Once you feel tinnitus or hearing loss, or if your existing tinnitus or bad hearing worsens, go to the ENT department of the hospital as soon as possible for an otologic examination and hearing test. If necessary, an MRI of the internal auditory tract is needed to rule out internal auditory tract and pontocerebellar horn lesions. If it is diagnosed as sudden deafness, treatment should be given as soon as possible. The first choice is infusion, mainly to improve inner ear circulation and nerve nutrition in the inner ear; it needs to be combined with oral or intramuscular injection of vitamin B12; depending on the situation, hormone therapy can be used (more used abroad), absolute ban on smoking and alcohol, ensure sufficient sleep and rest, including hearing rest, and it is best not to make phone calls and listen to headphones. There is no unified special medicine for the above treatments, and sometimes several methods of treatment are needed in combination. Generally 7 days is a course of treatment. Some patients improve significantly in the first course of treatment, while others do not improve significantly even after regular treatment. Patients with sudden deafness who have difficulty in registering can seek additional numbers from me (due to the large number of outpatients, limited to patients with sudden deafness) in order to get treatment as soon as possible and avoid delaying their condition.
