Pus flowing from the patient’s ears is mainly considered in two aspects: the first is that the patient may dig his ears frequently, which is especially likely to cause the mucous membrane to break down, and the water may enter the ear canal when the patient washes his hair and face, which will easily lead to the formation of infection in the mucous membrane of the external ear canal, so pus will flow from the patient’s ears. In terms of treatment, it is best to rinse repeatedly with saline to clean out the pus thoroughly and then treat with levofloxacin ear drops. The second one is acute purulent otitis media, which is often caused by the patient’s secretory otitis media, where the inflammation is particularly severe and subsequently leads to the perforation of the eardrum and the appearance of pus. In terms of treatment, the patient needs to take oral levofloxacin hydrochloride capsules for anti-inflammatory purposes, followed by oral eucalyptus pinene enteric softgels to promote the outward flow of pus, and after active treatment, the condition should improve significantly.
