Patients with pus in the ear are advised to sleep on their side as much as possible to facilitate the pus draining out of the pus-ridden ear on its own. Clinically, for patients with chronic purulent otitis media, it is recommended to do the following treatment treatment. It is recommended that patients go to an ear clinic where they can have their doctor perform ear drops with hydrogen peroxide drops. The doctor can use an aspirator to suck the pus out of the ear canal and then use levofloxacin ear drops and perform ear bath treatment, which will ensure that the drops go into the middle ear cavity to achieve a better anti-inflammatory effect. Such patients are recommended to do pus culture of ear canal secretions to see what drugs the patients are sensitive to and choose sensitive antibiotics so that the treatment effect is very good. Patients with chronic suppurative otitis media who have rhinitis, sinusitis and other upper and lower respiratory tract infections should be treated actively for these diseases, otherwise it is difficult to cure otitis media. In the case of long-term chronic suppurative otitis media where medication is ineffective, or in the case of sarcoidosis or cholesteatoma growing inside the ear, surgery is recommended.
