Patients with ear infections often experience swelling of the auricle, pain in the ear, and swelling and pus in the ear canal. This can be divided into inflammation of the auricle, inflammation of the external ear canal, and inflammation of the middle ear. The treatment differs depending on the location of the inflammation and the patient’s performance. Acute inflammation of the auricle is mainly characterized by redness, swelling and pain in the auricle, and in some cases, migraine headaches on the affected side, and in severe cases, fever. Oral medications are generally used to treat the condition, with penicillin antibiotics, such as amoxicillin, being the first choice. Glucocorticoids such as dexamethasone and prednisone acetate can be added as appropriate. Inflammation of the external auditory canal is mainly characterized by pain and discomfort in the ear canal. On examination, congestion and swelling of the inner wall of the ear canal can be seen, and in severe cases, the narrowing of the external auditory canal is obvious and the tympanic membrane cannot be seen, and some patients also have symptoms of pus flowing from the ear canal. For the treatment of otitis externa, oral medication is used to treat the same inflammation of the auricle. If the ear canal is running with pus, it can be cleaned with hydrogen peroxide and then soaked with oxyfloxacin ear drops. In the case of inflammation of the middle ear, patients may experience ear pain, headache, pus flowing from the ear canal, hearing loss, and other symptoms, and in severe cases, serious intracranial and extracranial complications may occur. For the treatment of otitis media, oral medication is the same as for inflammation of the ear, and the cleaning method when there is pus in the ear canal is the same as the treatment method when there is pus in the external ear canal. Usually, the ear canal should not enter water to avoid causing inflammation in the middle ear cavity; you should also try to avoid catching a cold. If there are serious complications, seek medical attention in a timely manner. Most patients with chronic otitis media require surgical treatment to achieve healing. Ear inflammation, which is a general term, requires identification of the inflamed area and then targeted treatment. Therefore, once the symptoms of ear inflammation appear, you can try oral anti-inflammatory drugs first, and if it does not improve, you should seek medical attention promptly.
