Whether a broken eardrum can heal on its own depends on the etiology of the disease. In general, most small perforations caused by acute inflammation or trauma can heal on their own, but large perforations, whether caused by verification or trauma, are less likely to heal on their own. The eardrum is thin and fragile and is prone to perforation when it receives injury or inflammatory damage. Once a perforation of the eardrum has occurred, it is important to maintain good hygiene in the ear canal and to keep the canal dry. If there is no ongoing inflammation in the ear canal, a small eardrum perforation will usually heal on its own in two to three months. If the eardrum has been ruptured due to severe trauma, it is important to have a definitive examination. In particular, an otoscopy and audiogram will help an experienced physician decide whether the patient should be conservatively observed or surgically treated, depending on the size of the perforation and the hearing loss. For eardrum perforations that are unlikely to heal on their own, early surgery to repair the eardrum is recommended. Eardrum repair surgery is a minimally invasive endoscopic procedure that can be effective in preventing infection and improving hearing. In general, the eardrum perforation should be analyzed according to the specific condition, keeping the external ear canal clean and dry, avoiding water and self medication, and in severe cases, going to the hospital for examination and treatment to prevent delaying the best treatment time and aggravating the condition. We also need to pay more attention to the diet, mainly a light diet, and to keep a good rest.
