Overview

Otitis media is caused eustachian tube dysfunction due to varying factors. Infection-based otitis media is usually caused by the pathogen causing nasopharyngitis, including bacterial and viral causes of upper respiratory tract infections. Other factors include allergies, airborne irritants, and sources of injury and rupture to the tympanic membrane. This includes physical injury, extremely loud noise, and sudden changes in atmospheric pressure.

Causes

Otitis media is caused by factors that lead to eustachian tube dysfunction due to mucosal congestion:^[1]

Infectious^[2]

Infectious causes of otitis media are usually the pathogen for preceding nasopharyingitis:^[3]

Bacterial infections:
- Streptococcus pneumoniae
- Moraxella catarrhalis
- Pseudomonas aeruginosa^[4]
- Nontypable Haemophilus influenzae
- Group A streptococcus
- Staphylococcus aureus^[1]
- Streptococcus pyogenes
Upper respiratory infection:

- Ear injury.
- Extremely loud noises.
- Sudden changes in air pressure.
