The cost of surgery to repair a tympanic membrane perforation is approximately$15,000. The main clinical symptom of tympanic membrane perforation is the frequent flow of pus from the external ear canal, sometimes accompanied by hearing loss and even tinnitus. In clinical practice, if the patient has a dry ear, the tympanic membrane perforation repair surgery can be considered. Pre-operative blood tests and middle ear CT are often required to determine whether the patient is suitable for the surgery. There are risks associated with the surgery, such as the risk of general anesthesia, non-viability of the implant or loss of the graft, and in some cases, a second surgery. After the surgery, the ear canal is filled with iodoform gauze, which is often compressed for about 10 days, after which the patient needs to visit the hospital for regular medication changes.
