First of all, the type of otitis media should be determined 1. Simple type: the most common, mostly appearing after upper respiratory tract infections, with pus flowing from the ear, mostly intermittent, mucous or mucopurulent, and generally not smelly. The amount varies, and the amount of pus increases when there is an upper respiratory tract infection, and the examination reveals a perforation of the central part of the tympanic membrane. 2. Bone ulcer type: Also known as necrotic or granulomatous type, it mostly comes from acute necrotic otitis media extended. The tissue destruction is more extensive and is characterized by persistent ear pus, with blood between the pus. 3. Cholesteatoma type, but not a true tumor, has a small amount of pus flowing in the ear, and may have white scales, bean residue-like material and bad odor. Sometimes headache and significant hearing loss may occur. Treatment Actively treat focal diseases of the upper respiratory tract, such as chronic sinusitis and chronic tonsillitis. The simple type is based on local medication: aqueous antibiotic solution or a mixture of antibiotics and steroid hormones, such as 0.25% chloramphenicol solution, chloramphenicol cortisone solution, and oxyfluoxacin ear drops, are available. For otitis media with osteochondritis, if the drainage is clear, local medication should be used, but attention should be paid to regular review. For otitis media with poor drainage or suspected complications and cholesteatoma otitis media, modified mastoid radical surgery or mastoid radical surgery should be performed early to completely remove the lesion and prevent complications. In cases of large tympanic membrane perforation affecting hearing, tympanic membrane repair or tympanoplasty is feasible about 2 months after dry ear. Precautions for local medication 1. Clean the pus in the external ear canal and middle ear cavity before medication is administered, using 3% hydrogen peroxide or boric acid water to clean it, and then swab it with a cotton swab or use a suction device to suck out the pus before medication is administered. 2.When the amount of pus is large, use water, and when the amount is small, use boric acid alcohol. Ear drip method The patient is in a sitting or lying position with the affected ear facing upward. Gently pull the auricle backwards and upwards and put 3 to 4 drops of medicine into the external ear canal. Then gently press the ear screen several times with your fingers to encourage the drug to flow into the middle ear through the tympanic membrane perforation. Change position only after a few minutes. Note that the ear drops should be as close to the body temperature as possible to avoid vertigo.
