Cholesteatoma otitis media

Chronic suppurative otitis media is divided into three types: simple type, bone ulcer type, and cholesteatoma type. Cholelipoma otitis media belongs to the third type, which is also the most serious of these three types of otitis media and is prone to complications. The so-called cholesteatoma is the accumulation of the epithelial detachment in the middle ear. The more it gathers, the more it expands continuously, causing damage to the adjacent bone. Nerves can cause facial nerve paralysis, and expansion into the skull can lead to life-threatening complications such as brain abscess. Therefore, once diagnosed as cholesteatotic otitis media, surgery must be performed. The main purpose of this otitis media operation is not to provide high hearing, not to prevent pus, but to prevent complications. Of course, during the surgery, doctors will do their best to help propose high postoperative hearing and dry ear rates. However, due to the disease, the dry ear rate after cholesteatotic otitis media is not too high, it is about 80%. Generally speaking, if the patient's condition meets the conditions of tympanoplasty, tympanoplasty is added during the operation, and the hearing after the operation will be improved. If there is no condition to perform tympanoplasty and only perform radical cholesteatoma, the hearing after the operation will not decrease. As for the pus still flowing, this is that the infection is not under control, that is, the purpose of dry ears was not achieved by the surgery. Change the medicine regularly, clean the operation cavity, perform bacterial culture and drug sensitivity tests on pus, and select extremely sensitive antibiotics for treatment according to the results of drug sensitivity tests.
