Scope of application: simple otitis media tympanic membrane perforation, ear trauma tympanic membrane perforation that does not heal for a long time. (Personal experience: small perforations are more likely to succeed) Process: After treatment with medication, the old skin at the edge of the perforation is removed, after which the tympanic membrane will first become congested and then thicken, and then begin to grow towards the center of the perforation. After the perforation is healed, the congestion and thickening of the tympanic membrane will begin to slowly subside, and the hearing will slowly improve and stabilize after six months to a year. If this method is successful, the hearing is better than the transplant method. Note: 1. It is good to have itchy water in the ear, the granulation tissue grows faster with water, and the granulation tissue will feel itchy when it grows, once every two to three days with drops. 2. It is forbidden to use cotton swabs to dig the ear, otherwise the new buds will be wiped away and the perforation will not heal. 3. Actively treat nasal disease. Depending on the situation, antibacterial agents are used to fight infection and sometimes blood-activating drugs are used to promote growth. Contact your doctor if you have any questions. Be confident and do not hesitate. Be on time for follow-up.
