Question
How is otitis media caused?
Answer
Otitis media is an inflammatory condition caused by pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes, and Staphylococcus aureus. It commonly affects children through the eustachian tube, external auditory canal, or primary middle ear infection pathways. Such infections may be associated with chronic nasopharyngeal diseases or delayed-onset otitis media, involving inflammation of the eustachian tube, tympanic cavity, and mastoid antrum.
