Perforation of the eardrum after being hit is also called traumatic tympanic membrane perforation, and irregular perforation of the tense part of the tympanic membrane due to trauma is the most common. The first thing to do is to make sure that no water enters the ear, even when bathing or washing hair, water vapor is not allowed to enter, and the ear must be kept dry, especially to prevent symptoms of infection. In the early stages of a perforation, you can take medications that promote healing, such as Yunnan Baiyao capsules. After a perforation occurs, try not to catch a cold or flu, and do not allow pinching the nose or closing the mouth to blow air into the ear. If the tympanic membrane perforation does not heal after conservative treatment, at this point only tympanic membrane repair surgery under local or general anesthesia can be considered.
