Whether an ear perforation can heal on its own depends on the specific condition, and cannot be generalized. Ear perforation, or tympanic membrane perforation, is commonly caused by trauma, otitis media, tumors, etc. If a traumatic tympanic membrane perforation is small and there is no infection after the perforation, the patient will recover well and most of them can recover on their own. However, if the perforation is large, or if infection develops after the perforation, it is usually difficult to heal completely on its own. In the case of tympanic membrane perforations caused by purulent otitis media, if the perforation is large and the infection is severe, it is also difficult to achieve a self-recovery. In addition, tympanic membrane perforations caused by tumors usually do not heal on their own, and surgical repair is an option for severe cases. After tympanic membrane perforation, patients need to pay attention to active prevention of infection by using alcohol wipes in the external ear canal to keep the ear canal clean and dry, avoiding the entry of foreign bodies and flying insects, and also preventing upper respiratory tract infections by avoiding forceful nose blowing.
