Causes: Otitis Media Acute otitis media is usually caused by Streptococcus pneumoniae or Haemophilus influenzae bacteria. It may also be caused by a viral infection by respiratory syncytial virus or influenza A virus. Chronic otitis media is often a symptom of food allergies.
Otitis Externa Otitis externa generally occurs when fluid or a foreign object becomes trapped in the ear canal and causes irritation. This often leads to infection by Staphylococcus aureus or Pseudomonas aeruginosa bacteria. This form of infection may also be caused by seborrheic dermatitis, neurodermatitis, contact dermatitis, atopic exzema, or psoriasis. Climactic or chemical factors can also be involved. Otitis externa can also be caused by an irritation due to the drainage of the middle ear for those suffering from chornic otitis media. This type of infection is called chronic otitis externa. Very rarely, it can also be caused by leprosy, sarcoidosis, syphilis, tuberculosis, or yaws.
