Malassezia otitis:   “ Ears looking at you, kid”

     A number of patients who visit Animal Dermatology Clinic often have issues with their ears. Owners report that their pet will constantly shake his head or scratch at their ears. Many of these pets will have an odor or discharge emanating from the ears. These are often symptoms of otitis externa, an inflammation of the outer ear canal.
Many of the cases of otitis externa are complicated by yeast infections. Often these ear problems are a result of a primary disease such as allergies, keratinization defect, hormonal influences or parasitic problems and the bacterial and yeast organisms are not the true “primary” cause of the otitis. Malassezia pachydermatis is the most common yeast found in diseased ears and while a normal ear will have evidence of this yeast, a red and inflamed ear will have high numbers of yeast. (See photo, next column) To determine the amount of yeast present in the ear, the veterinarian will carefully swab the outer canal, transfer the exudate to a glass slide and view the sample with a microscope.

     The treatment of otitis externa consists of therapy for the existing infection and also for the underlying condition that allowed it to develop.
Long standing infections may require an ear “flush” to remove debris and is best performed under general anesthesia. During this procedure the doctor will use a video otoscope for a detailed look in the ear canal. This allows for a thorough assessment of the eardrum and canal, and to remove all the material that is present.
      A medical treatment for otitis usually requires the pet owner to be actively involved in the process. Thorough cleaning of the affected ears is important while being mindful of using a deft touch in this delicate area. If a medicated liquid solution is prescribed, the doctor will give instructions how to apply and massage the pet’s ears to get good application. Finally, oral medications may be prescribed.
