The principles of treatment for this disease are to eliminate the cause, control the infection, remove the lesion, clear the drainage, and restore hearing as much as possible. 1. Etiological treatment Cure acute otitis media in time and actively treat upper respiratory tract infection. 2. Local treatment (1) In the quiescent stage, local medication is the main treatment. Local medication can be chosen according to different lesions, usually using peroxide water to wash the ear and then using antibiotic water solution or a mixture of antibiotics and glucocorticoids to drip the ear. (2) In the active stage, the main focus is to remove the lesion and prevent complications, and try to preserve the hearing-related structures. Local medication may be used for observation and surgical treatment depending on the condition. Generally, there will be a period of exudation after otitis media surgery, which varies according to the nature and severity of the lesion. Generally, dry ears can be obtained after three months, and the external ear canal is usually cleaned with small cotton swabs to avoid blockage of the external ear canal by secretions.
