Otitis media can be divided into acute purulent otitis media, chronic purulent otitis media and secretory otitis media, and should be treated with appropriate ear drops according to medical advice after examination to clarify which type it is. 1. Acute purulent otitis media: use phenol glycerin ear drops before tympanic membrane perforation, and use oxyfloxacin ear drops and compound rifampicin solution after tympanic membrane perforation, and apply boric acid ethanol glycerin, boric acid ethanol, and When the inflammation gradually recovers, ear drops such as boric acid glycerol, boric acid glycerol and chloramphenicol glycerol can be applied. In addition to treatment with ear drops, mastoidectomy and drainage are also feasible for acute purulent otitis media. 2. Chronic purulent otitis media: can be treated with ear drops such as oxyfloxacin, chloramphenicol and compound rifampicin solution. When the mucous membrane of the tympanic chamber is moist and there is less pus, boric acid ethanol, boric acid glycerol, chloramphenicol glycerol, etc. can be applied to promote the drying of the ear canal, and in addition, tympanoplasty can be applied to promote the discharge of secretions. 3. Secretory otitis media: Generally, ear drops are not used for treatment, and nasal decongestants and nasal sprays containing glucocorticoids can be applied for daily nasal spraying, and drugs can also be injected by blowing into the eustachian tube through a catheter or tympanic membrane puncture, and localized with Dexamethasone or prednisone can be used topically to relieve pain and fever. In addition, during the treatment period, patients with otitis media should pay attention to a light diet and avoid spicy and stimulating foods such as ginger, raw garlic, raw onion, chili and curry. Ensure sufficient sleep and avoid overworking and staying up late. Avoid getting water in the ear canal, frequent ear picking and wearing headphones as a way to prevent the onset of otitis media.
