The professional term for eardrum repair is tympanic membrane repair. After trauma to the eardrum or otitis media resulting in perforation, repairing the eardrum can restore the normal anatomy of the middle ear, improve hearing, and prevent pus and water from flowing from the ear. The specific procedure for eardrum repair is roughly as follows: The incision for eardrum repair can be made behind the ear or inside the ear, and either incision will leave no visible scars after surgery. The material used to repair the eardrum is usually the fascia on the surface of the temporalis muscle around the ear, or the cartilage membrane of the ear screen, which is scraped off the epithelium on the tragic side of the tympanic membrane perforation, the tympanic chamber is filled with absorbable gelatin sponge, the temporalis muscle fascia or cartilage membrane is lined on the inner or outer side of the eardrum, and the surface is filled with absorbable sponge, so that the fascia or cartilage membrane fits closely to the eardrum. After two weeks, the gelatin sponge dissolves and is absorbed. After that, the epithelium grows inside and outside the fascia. Eardrum repair is still a relatively simple procedure, but if there is a rupture of the eardrum, it is important to operate as soon as possible.
