Tympanosclerosis, also known as otosclerosis, is mainly due to the hardening of the stapedial base plate inside the middle ear tympanic chamber, which then causes abnormalities in the conduction of the auditory tuberosity or auditory chain, and because the mobility of the auditory chain is restricted, there may be hearing loss when listening to sounds. For now, the main treatment method is to consider surgery. First, surgery can be done to shake the hearing bone to see how much the hearing bone moves. If the hearing bone chain moves better after shaking, the surgery will be over and the hearing can be improved significantly. Secondly, if the hearing chain is not moving well after the surgery, the hearing can be improved by replacing the artificial bone. Overall, the efficacy of the surgery is good, but the surgery is difficult and generally requires a larger or top hospital to carry out.
