Sudden deafness, or “sudden deafness”, is a sudden, unexplained sensorineural hearing loss, usually within minutes or hours, but rarely within 72 hours, with no fluctuation. Sudden deafness can occur in one or both ears, and is often accompanied by tinnitus before and after the onset of the disease, with some patients experiencing vertigo, nausea, and vomiting at the beginning of the disease. Sudden deafness, especially when accompanied by significant vertigo, is often severe and difficult to treat. Sudden deafness is an otologic emergency and early treatment after onset is advocated. Therefore, patients with sudden hearing loss should be seen in a hospital in a timely manner, and the doctor should make a clear diagnosis through hearing tests and other necessary examinations. It is necessary to exclude other serious diseases, especially serious intracranial diseases, such as auditory neuroma patients who also have the onset of sudden deafness. Treatment of sudden deafness The Ear, Nose and Throat Branch of the Chinese Medical Association, Ear Group, has proposed standardized treatment opinions and recommended treatment options based on comprehensive clinical treatment experience: 1. Glucocorticoids, which require attention to contraindications and drug side effects, advocate early application, short-term application for 3-5 days, and adequate impact. 2, neurotrophic drugs: vitamin B group drugs, methylcobalamin, nerve growth factor, monosialic acid ganglioside, etc. 3.Improve microcirculation improvement, improve the inner ear blood supply and oxygenation drugs: including vasodilators commonly used drugs such as ginkgo biloba Damo, compound Danshin, ShuXin, GeGuanXin, Jinadu and other herbal extracts; anticoagulants such as fibrinolytic enzymes, prostaglandin, etc., other such as hyperbaric oxygen and other multi-method, multi-program treatment. 4. Controversial attempts: For refractory sudden deafness, especially for patients with unsatisfactory treatment results, it is also necessary to do the best possible treatment: controversial methods include: intra-drum injection of hormonal drugs, subperiosteal injection of hormones behind the ear, which requires the patient’s consent and attention to prevent complications; other methods such as Chinese herbal medicine: including acupuncture and massage, herbal prescriptions, etc. In some cases, even with prompt and aggressive treatment, the hearing cannot be saved. For patients with bilateral or profound hearing loss, hearing aids or cochlear implants are recommended.
