A tympanic membrane perforation of this length cannot heal itself. Because the edge of the perforation has keratinized, the ability to regenerate cannot exist, and it needs to be surgically treated by creating a fresh wound and then surgically treated with a repair material. If the perforation is caused by otitis media, it needs to be combined with a CT of the ear, and the infection has to be controlled before surgery. In cases of combined middle ear cholesteatoma, an incision may be made behind the ear and repair surgery done at the same time. After tympanic membrane repair, it is necessary to keep the ear filled for about two weeks, and there may be a stuffy feeling in the ear at the time of follow-up, mainly due to the over-thickness of the repair material. As long as the surgery is successful, you can pinch and shut up and puff more often, so as to promote the activity of the repair material, which will gradually become thinner and thinner, and the majority of the patients will be able to relieve the stuffy feeling of the ear significantly after half a year.
