It takes about a month to two months for the eardrum to grow back after eardrum repair, and each person is different and recovers at a different rate. Eardrum repair is a common surgical procedure to treat chronic otitis media and perforated eardrums. Perforated eardrums are often caused by trauma or inflammatory factors, and can be repaired surgically if the perforation does not heal on its own. After the surgery, it takes about one to two months for the eardrum to grow back. Each person’s condition is different and there are individual differences. Eardrum repair is a minimally invasive surgery, operated under general anesthesia under otoscopy, which can take the cartilage of the ear screen or temporal muscle fascia to repair the broken eardrum. After the surgery, do not eat spicy food, avoid water in the ear canal, avoid blowing the nose bilaterally at the same time, and take medication under the guidance of the doctor.
