The extent to which hearing can be restored after tympanic membrane repair surgery varies from person to person. For people with hearing loss caused by a simple tympanic membrane perforation, the extent to which hearing can be restored after tympanic membrane repair surgery can be up to about 30 decibels higher than that before surgery.
The age of the patient, the severity of the disease, the ability to repair the wound, the physical condition, the graft material, and other factors can all affect the degree of hearing improvement after tympanic membrane perforation repair. The vast majority of patients will experience some degree of recovery after surgery, but it is very difficult to return to the level of hearing that existed before the perforation.
According to statistics, 62% of the patients have their hearing restored to the daily application level of 30 decibels or more after surgery, while some patients have no significant improvement in their hearing after surgery, or even have a decrease in their hearing after surgery.
For those who have severe or prolonged inflammation in the middle ear, in addition to tympanic membrane repair, surgery is also required to clean up the inflamed tissue in the middle ear and carry out hearing reconstruction, and the degree of postoperative hearing recovery is not guaranteed in such cases.
Patients who need to undergo tympanic membrane repair surgery should consult with their surgeon before the surgery to fully understand the relevant information about the surgery, follow the doctor’s instructions to actively standardize the treatment, and comply with the doctor’s instructions for post-operative care, as well as the need for timely rechecks.
