What is Laryngeal Paralysis?

Laryngeal Paralysis occurs when the muscles are not moving the larynx normally, normally due to nerve dysfunction, specifically affecting the arytenoid cartilage and the vocal folds. Normally, these structures are abducted (pulled outwards) out of the airway during inspiration to allow air into the trachea. In Laryngeal Paralysis, they do not move and therefore cause partial obstruction of the airway.

Which breeds are most affected?

Laryngeal Paralysis is most commonly seen in medium to large breed dogs over 10 years of age, with males being more prone than females.

Breeds known to be more predisposed are:

  • Labrador
  • Golden Retriever
  • Irish Setter
  • Pointer
  • Great Dane
  • Newfoundland
  • St Bernard
  • Dalmatian
  • Siberian Husky

What are the symptoms of Laryngeal Paralysis?

Laryngeal paralysis often develops slowly, and symptoms may appear gradually. One or both sides of the larynx can be affected, but symptoms are often more obvious when both sides are affected. Symptoms can also be ore pronounced when the weather is warmer, during or after exercise, or when a dog is excited and/or stressed.

Common symptoms include:

  • Exercise intolerance, or unwillingness to exercise is the most frequently reported sign
  • Noisy breathing, especially when breathing in
  • Change in bark (dysphonia) affects roughly 50% of dogs
  • Discolouration of the gums to a blue-purple colour, especially after exertion
  • Fainting, particularly after exercise
  • Coughing whilst eating or drinking

How is Laryngeal Paralysis diagnosed?

Usually, the age, breed and clinical signs of the dog can lead to a suspicion of Laryngeal Paralysis. A clinical exam will be performed and it may be recommended that the dog have a light sedation to be able to examine the larynx properly. Radiographs of the chest may be taken depending on the dogs age/previous clinical history.

How is Laryngeal Paralysis treated?

In severe or bilateral Laryngeal Paralysis, surgery is often indicated. A “Laryngeal Tie Back” surgery involves tying back the arytenoid cartilage on 1 or both sides, with a permanent suture which prevents it becoming an obstruction when breathing. Surgical correction is often very successful in reducing or eliminating clinical signs.
