Otitis media

Otitis media is inflammatory lesions that affect all or part of the structure of the middle ear (including the eustachian tube and tympanic sinus and the mastoid air cell). Most of them are non-specific inflammation, especially in children. Can be divided into non-purulent and suppurative two categories. Non-suppurative patients include secretory otitis media, barometric otitis media; pyogenic patients have acute and chronic, and specific inflammation is too rare, such as tubercular otitis media. Secretory otitis media, acute suppurative otitis media, and cholesteatoma otitis media and barometric otitis media are common.
