The causes of ringing ears like earwax include outer ear lesions, middle ear lesions, cochlear lesions and so on. 1. External ear lesions: When foreign bodies are deposited in the external ear canal, or when cerumen moves and rubs against the tympanic membrane, the sound is produced, causing tinnitus. 2. Middle ear lesions: such as secretory otitis media, purulent otitis media and other diseases, can often cause different degrees of conductive deafness and tinnitus. 3. Cochlear lesions: Meniere’s disease, vestibular neuritis, etc. can cause tinnitus. 4. Post-cochlear lesions: diseases such as acoustic neuroma, meningioma, cholesteatoma, etc., can compress the auditory nerve, resulting in mechanical stimulation and abnormal nerve impulses. It is recommended that patients seek medical treatment in time to find out the cause of ringing in the ears, and actively cooperate with the doctor to avoid aggravation of the condition.
