In life, if patients have difficulty hearing clearly in one ear, they should go to the ENT department of the hospital for examination and treatment in time to avoid delaying the condition and affecting normal work. Patients can improve pure tone audiometry and acoustic conduction resistance to clarify the current hearing level, and also need to clarify the cause of hearing loss. If the hearing loss is caused by inflammation, the patient should be treated with anti-inflammatory therapy. Amoxicillin injection or cefoperazone injection are commonly used in clinical practice, and skin tests are required before use. If the patient’s hearing loss is caused by poor blood circulation and nerve nutrition, treatment should be actively improved circulation and nerve nutrition. Ginkgo biloba liquid injection, thromboxane injection and prostil injection are commonly used clinically to avoid delay in treatment.
