The eardrum can be repaired, if it is caused by trauma, first avoid water in the ear, avoid catching a cold, avoid blowing your nose hard, and don’t put medicine in your ear. You can take appropriate oral anti-inflammatory medication to prevent tympanic membrane infection and go to the hospital once a week to review and observe the condition of the eardrum. If there is no tympanic membrane infection, most of them will be repaired within 1-6 weeks. If the tympanic membrane is perforated due to acute suppurative otitis media for the first time, the tympanic membrane will be repaired on its own by cleaning the purulent secretions in the ear canal with hydrogen peroxide, taking ear baths with anti-inflammatory drops, and taking oral anti-inflammatory medication. However, if the tympanic membrane is not healed after trauma or if acute suppurative otitis media recurs and causes the tympanic membrane wound to not heal, tympanic membrane repair can be performed 1-3 months after the dry ear. If the tympanic membrane perforation is relatively small, the tympanic membrane can be repaired by local filling with fat particles; if the wound is relatively large, a fascial graft repair can be considered.
