Acute deafness mainly includes sudden deafness and blast deafness. Patients should clarify the cause according to the report results of blood routine, otoscopy and hearing examination issued by the hospital, and then carry out targeted treatment. 1. sudden deafness: mainly sensorineural hearing loss. It can also apply thrombolytic and anticoagulant drugs to reduce the level of fibrinogen in the blood, and can also choose hyperbaric oxygen therapy to improve the inner ear hypoxia, unblock microcirculation, and promote the recovery of auditory function; 2. Blast deafness: hearing damage caused by sudden strong blast and noise. Most of the mild blast deafness can be recovered. In the early stage of middle ear injury, the outer ear canal should be kept clean and dry, and ear drops should not be used, and antibiotics can be applied for combined infection. Inner ear damage can be treated with hyperbaric oxygen. Those with abnormal vestibular function can be treated with antiemetic and sedative drugs, and if necessary, further treatment with hormones and nerve-nourishing drugs can be considered. During the treatment process, patients should pay attention to regulating bad emotions to avoid depression, frustration and other bad emotions from affecting recovery. Physical exercise can be performed appropriately to increase body resistance and immunity. In addition, the sleeping environment should be quiet and comfortable to promote hearing recovery.
