It is possible for a ruptured tympanic membrane to repair itself. Clinically, traumatic perforation of the tympanic membrane is common. Most of these perforations are irregular and are mainly tension perforations. The eardrum may be able to repair itself if the patient takes the following measures: First, keep the ear canal dry and hygienic, no dirty water, and no dirty things. Second, avoid colds, rhinitis, sinusitis, and other respiratory infections, as these respiratory infections can easily enter the tympanic cavity through the eustachian tube and induce infection within the tympanic cavity. Once the infection is localized, it will be very difficult for the tympanic membrane to heal. Third, under the guidance of the clinician, antibiotics can be applied to prevent and control the infection. As long as the tympanic membrane is not infected locally after the traumatic perforation, most patients have the possibility of healing well within two months. Fourth, if the tympanic membrane has not grown well after two months, or if there is a local septic infection within two months, anti-inflammatory treatment is needed in this case, and tympanic membrane repair surgery may be required after the inflammation is under control.
