Total Ear Canal Ablation
Otitis externa is a common problem affecting many dogs and cats and is often secondary to underlying dermatological issues such as allergies.
The underlying change in the normal ear environment leads to increased production of cellular material and bacterial or fungal overgrowths. The cycle can continue to progress to the point of permanent secondary changes to the ear canal including mineralization of the cartilage and obliteration of the opening to the canal secondary to tissue proliferation. As a result, loss of control of the ear infection can quickly occur. Once the ear is no longer salvageable, a total ear canal ablation can be performed. With this procedure, the cartilage and associated diseased tissue of the ear is removed and the bone cavity of the middle ear emptied of debris.
Complications include facial nerve paralysis, postoperative infections, diminished hearing and vestibular disease.
In spite of the potential complications, most dogs respond extremely well with improved quality of life.
