Deep in the ear, at the end of the external auditory canal, there is a layer of gray things. Translucent membrane, which is the boundary between the external auditory canal and the middle ear, is responsible for conducting sound waves to produce hearing, also known as tympanic membrane. Loud noise caused by inflammation, trauma or explosion can lead to eardrum perforation. Perforation of eardrum can be repaired by surgery to restore hearing.
The eardrum is broken due to trauma. If there is no infection, most of it can heal naturally. If you still can't recover after a few months, you can consider repairing the eardrum. The eardrum is divided into tension part and relaxation part. For the small perforation of the tense part of the eardrum, the operation method is simple and can be implemented in the hospital outpatient department. If it is a big perforation of the eardrum or a loose perforation, it depends on the specific situation. It is necessary to examine the mastoid process of the middle ear to determine whether the eardrum can be repaired. This operation is medically called tympanoplasty.
Simple eardrum repair must meet the following conditions: it must be 2-3 months after the ear pus stops. Tympanic membrane perforation is located in the tension part. The eustachian tube communicating with the middle ear and nasopharynx should be unobstructed. Deafness is conductive rather than neurological and can be determined by audiometry.
Using a microscope to improve the success rate of surgery It is worth mentioning that for patients with chronic otitis media and perforation of eardrum, many patients can use eardrum regeneration without surgery under this treatment method, which is hereby explained. First of all, we should understand the structure of the middle ear cavity and the characteristics of the eardrum itself. The eardrum itself can be divided into three layers: the outer layer is the flat cell epithelial layer, the middle layer is the fibrous layer, and the inner layer is the mucosal layer. Only the outer layer has stronger regeneration ability. In the past, most surgical methods were inserting artificial eardrum (mostly muscle membrane) or interposing cardiac membrane (fibrous layer). But the method of outpatient service is very different. It is to remove the granulation tissue in the middle ear cavity, remove the edge of the eardrum (inactive tissue caused by long-term inflammation), and remove the lesions that will affect the external auditory canal (such as pus caused by bacterial infection, granulation, fungal infection, etc.). ), and thoroughly remove the middle ear cavity and external auditory canal with liquid medicine, and then trim the perforation edge of the eardrum, and that's it.
Because this method is different from the surgical method, it can complement each other to improve the success rate of eardrum healing. Some patients can also be treated with this method to promote the regeneration of eardrum after surgical failure. At present, all patients receiving treatment have perforation of eardrum (some are unilateral and some are bilateral). After a period of treatment, many people's eardrums have healed.
