Tympanoplasty is a very common procedure in otolaryngology, mainly used for the treatment of chronic middle ear mastoiditis, cholesteatoma-type otitis media, otosclerosis, trauma-induced disorders of the middle ear sound transmission system and other related diseases. The types of this surgery are particularly common, and several of them are selected for analysis below: 1. Simple tympanic membrane repair surgery is very much used clinically. Some patients have chronic suppurative otitis media, the history of the disease is not very long, there is no obvious flow of pus in the tympanic chamber, there are no changes such as granulation or cholesteatoma in the tympanic chamber, and only perforation of the tympanic membrane exists. In this case, simple tympanic membrane repair surgery can be done, taking the cartilage of the ear screen or the fascia of the temporalis muscle behind the ear as a graft of the tympanic membrane, which can be repaired after the repair, and can be done by such techniques as the laminated method, the built-in method, or the external method. Patients with traumatic tympanic membrane perforation can also undergo simple tympanic membrane repair surgery when it has not grown well for 2 months.2. Tympanic membrane repair surgery plus auditory chain reconstruction surgery, where the auditory chain is mainly taken from the patient’s own anvil bone or allogeneic auditory chain, connecting the hammer bone to the stapes for treatment, is slightly less expensive because there is no need to apply the transplanted auditory chain.3. Tympanic membrane repair surgery plus auditory chain reconstruction surgery, where the auditory chain reconstruction is The procedure is more complicated and the patient’s lesion is more serious.
