Patient's question:
How does otitis media occurDoctor's answer:
The main pathogens causing otitis media are Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes, Staphylococcus, and others. Children, especially those who enter the middle ear through the eustachian tube, external auditory canal, or primary middle ear, often suffer from chronic otitis media through the nose, chronic pharyngeal lesions, and delayed otitis media. Otitis media includes inflammatory lesions of the entire or partial structures of the eustachian tube, tympanic cavity, and mastoid cavity.
