The tympanic membrane is a membranous structure that divides the outer and middle ears and is usually only 0.1mm thick, so it is prone to breakage and perforation when subjected to external forces or sudden changes in air pressure. Symptoms of tympanic membrane perforation include hearing loss, ear congestion, tinnitus, and ear pain. In case of tympanic membrane perforation, the treatment methods are as follows: 1) for traumatic tympanic membrane perforation, the patient can usually wait for the tympanic membrane perforation to heal itself under the premise of preventing infection, and the patient can usually repair himself after 1-2 months; 2) if infection occurs, or if the perforation is large and the patient does not heal himself after 1-2 months, tympanic membrane repair surgery can be considered; 3) if the tympanic membrane is perforated due to otitis media, it can be repaired after the inflammation has subsided. perforation, tympanic membrane repair surgery can be done during the inflammatory resting period, i.e., when there is no inflammation. Tympanic membrane repair materials are usually taken from autologous materials, such as the posterior temporalis fascia and the cartilaginous membrane of the preauricular screen. The repair methods are usually external, laminated, or internal, and most of them are now internal. The built-in method involves first making a trabecular surface at the edge of the tympanic membrane and placing absorbable materials, such as nanoabsorbent gelatin sponge, in the tympanic chamber. The graft is then laid on top of the filling of the tympanic chamber, allowing the tympanic membrane to recover and fit together with the repair material, which will slowly grow and become one piece.
