In life, many patients come to ENT clinics for sudden deafness, which has no clear etiology. The main treatment is the application of drugs to improve circulation and nerve nutrition, as well as oral hormone shock therapy to reduce the state of congestion and edema in the inner ear. Before the use of hormones, it is necessary to clarify whether the patient has any absolute contraindications to the use of hormones, and the specific dosage needs to be used under the guidance of a doctor. Clinically commonly used drugs to improve circulation include prostaglandin injection, vincristine injection, or hemosiderin injection, which can be selectively applied by patients. Neurological drugs mainly include sodium cytarabine capsule, methylcobalamin dispersible tablets, or adenosine cobalamin injection for injection, and active treatment for about 7-10 days should normally improve the condition. At the same time, you can also try acupuncture and hyperbaric oxygen therapy, which are also clinically effective.
