Whether the eardrum, or tympanic membrane, can heal itself after perforation is related to the cause of the eardrum perforation, the degree of damage, and the infection. In traumatic tympanic membrane perforations caused by traumatic injuries such as gun discharge and air pressure differences, the eardrum can usually heal itself within two months with emergency treatment of the trauma and control of infection. If self-healing is not possible, tympanic membrane repair can be performed provided the ear is dry. For tympanic membrane perforations due to infection and inflammation, the first step is to control the inflammation and ensure that it does not bleed pus. Very small perforations can usually heal on their own. If the inflammation is severe, with persistent or intermittent ear discharge and resulting in a large perforation, this condition is difficult to heal on its own and requires active treatment. If the patient has a perforated eardrum with no possibility of self-healing or recurrent episodes, do not worry too much. It is recommended to visit the ENT department of the hospital and cooperate with the treatment under the guidance of the doctor.
