Treatment of traumatic tympanic membrane perforation The tympanic membrane can heal on its own after traumatic rupture and perforation. Because both sides of the eardrum are rich in blood vessels that anastomose with each other from the outside in, the ability to repair is very strong. However, the following points must be noted, otherwise it will be infected by bacteria and cause purulent otitis media, which will be more difficult to treat. 1. Keep the external ear canal clean and dry. You can disinfect the external ear canal with alcohol after trauma, wipe and remove foreign bodies and cerumen from the external ear canal. Do not remove the blood crust attached to the eardrum to avoid bacterial infection. Use sterilized cotton to gently plug the outer ear canal opening to prevent dirt from entering the ear and causing infection. 2. Do not rinse the outer ear canal with water or use any medication to drip the ear, because this is not only not beneficial, but can also cause bacteria to enter the middle ear and cause infection. 3. Do not blow your nose with force. If you have snot, inhale it into your mouth and spit it out. You can also take some anti-inflammatory drugs to avoid infection. If an infection occurs and causes purulent otitis media, it should be treated as otitis media. If the tympanic membrane perforation fails to heal and close, doctors often use the following methods of treatment: 1, cauterization patch method, using 30% silver nitrate or 50% trichloroacetic acid cauterization of the edge of the perforation to make it a fresh wound, and then paste a thin sheet, such as plastic film or garlic film, etc., new tissue along the patch to the center of growth, generally a few weeks to heal. 2, stimulation therapy, scraping the epithelium at the edge of the perforation to promote tissue regeneration, and then drops of 5% urea boric acid solution to accelerate repair. 3.After the above treatment fails, surgical method can be used to repair the perforation, and now most of them choose their own cartilage membrane, fascia, etc. as repair materials.
