Acute suppurative otitis media is an acute purulent inflammation of the middle ear mucosa, mostly caused by bacterial infection. Main causes: 1. Rhinitis, sinusitis, tonsillitis and pediatric adenoid hypertrophy caused by cold. When the above diseases occur, bacteria enter the middle ear from the nasal cavity and oral cavity through the eustachian tube, causing acute purulent inflammation of the middle ear mucosa, via the eustachian tube (which is an important tube connecting the nasal cavity and the middle ear, mainly to regulate the middle ear air pressure, so that the middle ear air pressure and external atmospheric pressure to maintain equilibrium, in the event of nasal cavity sinus lesions, but also the main way for bacteria to enter the middle ear from the nasal cavity) infection route is acute purulent The main cause of the onset of otitis media. Secondly, when the eardrum is perforated, bacteria enter the middle ear through the external ear canal and the perforated eardrum, causing suppuration of the middle ear mucosa. 3. The bloodstream infection route Bacteria from other parts of the body flow into the middle ear with the blood circulation, causing acute purulent inflammation of the middle ear mucosa, which is extremely rare. The main clinical manifestations are ear pain, tinnitus, hearing loss, pus flowing from the ear canal, sometimes accompanied by fever, loss of appetite, vomiting and diarrhea (these symptoms are mostly seen in children). Treatment: 1. Early and adequate antibiotic antibacterial treatment, and strive for a complete cure to prevent the tympanic membrane from perforating or turning into chronic. Most of the cephalosporin antibiotic treatment until the symptoms disappear, and continue treatment for several days after the disappearance of symptoms, before stopping. 2. Since patients mostly have symptoms such as nasal congestion, runny nose and sore throat, in addition to anti-infection treatment, it is also necessary to add drugs for rhinitis and sinusitis to make the nasal cavity clear, which is conducive to restoring the smoothness of the eustachian tube and more conducive to draining the purulent secretions from the middle ear, which is conducive to the cure of otitis media. This treatment is more important than the first one and plays the role of a kettle. 3. Before the tympanic membrane is perforated, the use of antibiotic ear drops is not recommended, but after the perforation of the tympanic membrane, the use of antibiotic ear drops, such as oxyfloxacin ear drops, etc., will allow the perforation to heal on its own after the inflammation subsides, but if the perforation does not heal for a long time, tympanoplasty, also called tympanic membrane repair, is feasible. Note the following matters 1. Avoid dropping ear drops with color because it will affect the doctor’s observation; avoid dropping ear drops that can damage hearing, which can cause neurological deafness and often cause permanent hearing loss; avoid dropping in powder or oily drugs, which can cause blockage of the external ear canal and affect the outflow of purulent secretions, aggravating the condition and affecting the doctor’s observation. 2, pay attention to the correct method of blowing the nose: with nasal congestion, runny nose, blowing the nose must not pinch both nostrils at the same time, which may cause otitis media; the correct method is: press the side nostril with the index finger, gently, rhythmically with the other nostril outward, the nasal snot in parts, gently spray out; the same method to blow the other side of the nasal nasal snot.
