Treatment of suppurative otitis media is divided into an acute phase and a chronic phase. In the acute stage, i.e. the first attack of purulent otitis media, the treatment is mainly anti-inflammatory, with oral or intravenous antibiotics, usually penicillin or cephalosporin antibiotics being preferred, followed by external ear drops. Of course, before applying topical ear drops, the purulent secretions in the external ear canal should be cleared away first, so that the external ear canal can be kept clean before applying the drops to play a corresponding role. After treatment of acute otitis media, if there are recurrent episodes of otitis media that turn into chronic suppurative otitis media, chronic suppurative otitis media is also treated during acute episodes. However, if there is persistent pus flow, a CT examination of the middle ear mastoid should be performed first to check for the presence of granulation lesions in the middle ear and mastoid or the presence of combined polyps or cholesteatomas. If there are granulomas, cholesteatomas or polyps, surgical treatment should be considered. If there is no such condition and the symptoms are simply pus, the treatment should be oral antibiotics or ear drops, and local irradiation of the external ear canal and physiotherapy can be performed. In the quiescent stage of purulent otitis media, that is, when there is no pus infection, it is necessary to avoid water in the ear canal and to take care of the general condition at the same time. In the case of perforated eardrum, surgery for repair of perforated eardrum can be considered in the quiescent phase of suppurative otitis media.
