Tympanoplasty

In 1952, zöllner and Wullstein underwent tympanoplasty and classified these types of surgery into four types according to physiological functions. In recent years, due to the rapid development of tympanoplasty, surgical typing is required to reflect the following characteristics: various types of adaptation objects, approaches to clear lesions, osseointegration reconstruction, nature of sacral complexes, characteristics of new tympanic chambers, and Whether it is staged. Therefore, in addition to tympanic membrane closure repair, tympanoplasty can be divided into five categories: tympanic membrane and osseointegration (type I), combined approach tympanoplasty (type II), modified mastoidectomy plus tympanoplasty (open technique) (type III), stage tympanoplasty (type IV) and inner ear fenestration (type V). Treatment of diseases: tuberculous otitis media with tympanosclerosis Indication Chronic middle ear mastoiditis, cholesteatoma otitis media, tympanosclerosis, and defects in the middle ear sound system caused by trauma can be performed by tympanoplasty after acute inflammation control. Preoperative preparation 1, mastoid film, if necessary, take ct film to clearly understand the extent of the lesion. 2, hearing test electrical test and listening, sound guide anti-measurement, table tuning fork check. 3, eustachian tube function measurement with tympanic membrane repair. Preoperative examination can roughly determine the type of surgery, but sometimes it needs to be flexibly changed according to the specific circumstances during surgery. Surgical procedure Advantages of tympanoplasty surgery 1, can effectively treat all ear diseases and complications The tympanoplasty procedure minimizes the residual of the lesion by resecting all the cavities hidden in the lesions in the middle ear and surrounding bone, and fully restores the continuity of the ossicular chain. At present, the tympanic molding technology has been comprehensively upgraded, and the surgical indications have been expanded. All chronic suppurative otitis media can be treated at one stroke. 2. Repair the ossicular chain and reconstruct the hearing After the patient was treated with surgery, the perforation of the tympanic membrane was nearly normal. After reconstruction, the activity and continuity of the ossicular chain were good. The hearing was gradually improved after the operation and increased significantly after 3 months. 3, small surgical damage, less complications Tympanic stenosis surgery, under the microscope to remove lesions through the ear microscopy device, while repairing the tympanic membrane and reconstructing the ossicular chain, has the advantages of less surgical damage, less complications, and good results.
