The treatment of ear pus depends on its cause, and the severity of the condition. If the pus is a small amount of bright pus, most of them are caused by outer ear diseases, such as acute otitis, eczema of the outer ear canal, mycosis of the outer ear canal, etc., which require the doctor to clean the outer ear canal and then use the corresponding ear-spotting medication. If the pus is thick and sticky, the amount is relatively large, and even has a foul smell, most of them are caused by middle ear diseases, such as vesicular tympanitis, acute suppurative otitis media, middle ear tuberculosis and so on. Antibiotic ear drops should be used for ear bath treatment. If the pus is thick and serious, it needs to be cleaned with hydrogen peroxide and then antibiotic ear drops should be used for ear bath treatment. If the pus is accompanied by blood, it needs to be taken seriously, which is mostly caused by trauma to the external ear canal or middle ear tumors, and requires prompt medical attention. If it is a large amount of watery fluid, cerebrospinal fluid ear leakage needs to be suspected, and also need to seek help from an ear neurosurgeon as soon as possible. Because ear infections are prone to cause complications inside and outside the brain, when there is pus coming out of the ear to pay attention to, if the condition is serious go to the hospital in time to check, as soon as possible treatment, to avoid causing greater harm to the body.
