Bell's Palsy in Animals

Bell’s palsy is the medical name for paralysis that affects the face. Its causes, effects and treatment are common to all species. When Bell’s palsy occurs in pets, veterinary care should be sought promptly to ascertain the cause and provide appropriate care.

  1. Definition

    • Bell’s palsy is a weakness or complete loss of control on one side of the face. It is caused by an abnormality in the function of the seventh cranial nerve, also known as the facial nerve.

    Causes

    • The most common cause of facial paralysis is inflammation or infection of the inner and middle ear. Other possible causes include trauma, nerve disease or damage, and cancer.

    Symptoms

    • General symptoms include an asymmetrical appearance, difficulty or inability to blink, eye watering, drooping lips and drooling, lack of ear control, dropping food when eating and head shaking.

    Diagnosis

    • Diagnosis is usually made through observation of physical symptoms. Further testing will be done based on the symptoms observed in order to diagnose the underlying cause of the paralysis.

    Treatment

    • There is no set treatment for Bell’s palsy. Many veterinarians will prescribe an anti-inflammatory drug to try to reduce the effects of the palsy. Long term, the most effective treatment for the paralysis is management of the underlying condition.
