Eardrum perforation repair, also known as tympanic membrane repair, is actually a basic tympanoplasty, usually has the following sequelae: First, secondary infection in the middle ear cavity, mostly caused by colds, not paying attention to aseptic operation, often leading to transplantation of necrosis, detachment of the fascia, resulting in failure of the operation. Secondly, the transplanted tympanic membrane heals on the outside, that is, it does not survive in the expected normal position of the original tympanic membrane, and does not play a good role in hearing conduction. Third, the transplanted tympanic membrane is invaginated, the shed epithelium gradually accumulates, and secondary cholesteatoma will be formed in the long term. Fourth, secondary perforation of the tympanic membrane, that is, due to infection, center necrosis, so that the transplanted tympanic membrane breakage, perforation, resulting in surgical failure.
