In children, like adults, there is a difference between secretory otitis media and purulent otitis media; however, purulent otitis media is often referred to as otitis media. In the case of purulent otitis media, there is acute purulent otitis media and chronic purulent otitis media. Acute suppurative otitis media often occurs after a cold and is a complication of a cold secondary to a bacterial infection. Acute suppurative otitis media is a condition in which the inflammation is confined to the mucosa of the tympanic cavity and the inflammation in other areas is relatively mild. If acute suppurative otitis media is not treated in time or is not treated regularly, and the condition exceeds 8 weeks, the inflammation invades the mastoid periosteum and even the bone, then it has already extended to chronic suppurative otitis media. For the treatment of acute suppurative otitis media, systemic medication with sensitive and adequate antibiotics is required; in severe cases, glucocorticoids need to be added; if there is nasal cavity and sinusitis. Treatment needs to be carried out simultaneously. Pus in the ear canal needs to be cleaned by an otolaryngologist to keep the drainage open and avoid local and systemic complications. In the case of purulent otitis media, complete cure should be carried out in the acute stage. If it develops into chronic purulent otitis media, it is incurable and seriously affects the hearing. For children who have been cured of acute suppurative otitis media, close attention should be paid when there is a cold and runny nose to avoid the recurrence of acute suppurative otitis media.
