Patient's question:
7/26 eveningDoctor's answer:
Hello, the most common pathogens of otitis media are mainly Streptococcus pneumoniae, Haemophilus influenzae, etc. Therefore, it is necessary to prevent colds to reduce the occurrence of otitis media. Acute otitis media is an acute purulent inflammation of the middle ear mucosa, with the pharyngotympanic tube route being the most common mode of infection. After a cold, inflammation of the pharynx and nasal cavity spreads to the pharyngotympanic tube, leading to congestion, swelling, and impaired ciliary movement in the pharyngeal orifice and lumen of the tube. Pathogenic bacteria take advantage of this opportunity to invade the middle ear, causing otitis media.
