Surgery is necessary for cholesteatoma otitis media. The sooner the surgery is performed, the less damage is done to the area and the more ear function is preserved. If the cholesteatoma erodes the auditory bone, the surgery will cause hearing loss. If the condition is earlier than effective, hearing preservation type (hearing preservation) mastoid radical surgery can be done, which will preserve hearing. There are many specific surgical procedures for cholesteatoma otitis media, which vary depending on the location of the lesion and the degree of damage. It usually takes nearly a month or more to fully recover from surgery before epithelialization of the operative cavity is complete. Cholesteatoma type otitis media surgery is a basic otologic procedure that is not very difficult and can be completely treated in some tertiary care hospitals.
