Acute deafness may be related to emotional factors, cerumen embolism in the external ear canal, viral infection, sound stimulation, etc. The cause needs to be clarified according to the specific situation and CT, hearing examination, etc. 1. Emotional factors: When a person is emotionally agitated or anxious and on fire, adrenaline secretion increases, causing spasm in the small arteries of the inner ear, resulting in insufficient oxygen supply to the inner ear and causing sudden deafness. In addition, staying up late, overwork, poor rest and stress can also cause impaired blood circulation in the ear, which in turn causes acute deafness. It is recommended that patients should be treated with glucocorticoids and medications to improve microcirculation in the inner ear under the guidance of a doctor. In addition, actively changing the work and rest pattern to ensure enough rest and sleep can promote recovery. 2. Cerumen embolism in the external ear canal: If the patient does not pay attention to the ear canal hygiene, too much earwax and form embolism, after bathing or swimming the ear canal gets water, the earwax expands and blocks the sound transmission to the tympanic membrane, which causes sudden hearing loss and even inability to hear. Patients are advised to seek medical attention and have the cerumen removed by a professional physician, do not pull out the ear by yourself; 3. Viral infection: the factor of viral infection can cause congestion and edema of the auditory nerve, affecting the function of the inner ear and auditory nerve, leading to sudden deafness. Patients can actively carry out anti-infection treatment under the guidance of a doctor; 4. Sound stimulation: such as the sound of firecrackers ringing, coal mines blowing up rocks or car tires exploding when hitting the gas, etc. can cause perforation of the eardrum, resulting in hearing loss or even deafness. In this case, the state of the eardrum and the degree of deafness need to be evaluated under the guidance of a professional doctor, and then targeted treatment.
