Otitis Media in Chinchillas

Otitis media is an infection of the middle ear that often affects young chinchillas. There are two primary reasons for this condition: infection and external ear trauma. When the ear is injured, the injuries may serve as entry points for infectious bacteria which may cause infection. Also, the scar tissue that forms during healing of the wound can enclose the ear canal and trap wax and debris inside which in turn becomes a source of infection. The eardrum may become thick and swollen. The swelling may progress to the inner ear, which will result in the development of otitis media.

Usually the treatment of otitis media is through antibiotics unless the ear canal is closed. Regular cleansing and dressing are of utmost importance too for complete healing. The underlying causes of otitis media should be treated as well.


  • Disorientation
  • Fever
  • Pain in the ears


  • Respiratory infections
  • Trauma to external ear


Diagnosis is made by the clinical signs observed. Blood tests and swabs tests may also be administered.
