The inability to hear may be caused by cerumen (earwax) embolism, otitis media, sudden deafness, etc. The causative factors need to be removed as soon as possible, and reasonable medication should be used if necessary. 1. Cerumen embolism: It is mainly caused by excessive cerumen secretion, resulting in blockage of the external ear canal. If the cerumen is relatively small, it can be removed directly with tweezers. However, if the cerumen is large or hard, it is recommended to soak it in sodium bicarbonate solution first to soften the cerumen, and then flush it out afterwards. 2. Otitis media: For example, purulent otitis media, when there is a purulent reaction, it will block the ear, thus affecting the hearing. You need to use hydrogen peroxide to clean up the secretion as soon as possible, and then use topical ofloxacin ear drops. 3. Sudden deafness: Sudden, unexplained sensorineural hearing loss. Treatment of low-sodium diet to reduce the possible membrane labyrinth accumulation of water; glucocorticoids systemic or local application, such as tympanic cavity injection, postauricular injection, etc., usually commonly used methylprednisolone sodium succinate, etc.; improve microcirculation drugs, such as ginkgo biloba leaf extracts; lowering the fiber drugs, such as bacitracin. There are many reasons why you can’t hear well in your ears, so you should consult the hospital in time, have a relevant examination, and standardize the medication and treatment after a clear diagnosis.
