Dogs with Laryngeal Paralysis: Surgical Considerations and Post-Operative Care162

Laryngeal paralysis is a debilitating condition in dogs that results in the inability of the larynx to fully open during inspiration, leading to significant respiratory distress. While there are various treatment options available, surgical intervention is often necessary to permanently correct the underlying cause and restore respiratory function.

Surgical Techniques

There are two main surgical techniques used to treat laryngeal paralysis in dogs:
Arytenoid Lateralization: This procedure involves permanently positioning one or both arytenoid cartilages (located in the larynx) laterally, preventing them from obstructing the airway during inspiration.
Tracheostomy: This procedure involves creating a permanent opening in the trachea (windpipe) to bypass the larynx and establish an alternative airway.

The choice of surgical technique depends on the severity of the laryngeal paralysis, the patient's overall health, and the surgeon's expertise.

Post-Operative Care

After surgery, dogs require careful monitoring and intensive post-operative care to ensure their recovery and prevent complications. Essential aspects of post-operative care include:
Respiratory Monitoring: Dogs with laryngeal paralysis are at increased risk of respiratory distress, particularly in the immediate post-operative period. They should be closely monitored for signs of respiratory compromise, such as difficulty breathing, coughing, or cyanosis (bluish discoloration of the gums).
Pain Management: Surgery can cause significant pain, so it is crucial to provide adequate pain medication to the patient. Anti-inflammatory medications may also be prescribed to reduce swelling and discomfort.
Nutritional Support: Dogs with laryngeal paralysis may have difficulty swallowing after surgery. They may need to be fed through a feeding tube until their swallowing function recovers.
Tracheostomy Care (if performed): If a tracheostomy was performed, it is essential to keep the stoma (opening in the trachea) clean and free of secretions. The dog may need to wear a tracheostomy tube or tracheotomy collar to prevent the stoma from collapsing.
Physical Activity: Dogs should be restricted from strenuous activity for several weeks after surgery to allow the larynx to heal properly. Gradual exercise can be introduced once the dog has fully recovered.

Potential Complications

While laryngeal paralysis surgery is generally safe and effective, there are potential complications that can occur, including:
Recurrent Laryngeal Paralysis: In some cases, the laryngeal paralysis may recur after surgery, requiring additional treatment.
Respiratory Distress: If the larynx remains obstructed post-operatively, the dog may experience respiratory distress and require additional procedures to establish a secure airway.
Tracheal Stenosis: In cases involving a tracheostomy, the trachea may become narrowed (stenosis) due to scarring, which can limit airflow.
Infection: The surgical site or tracheostomy stoma can become infected, requiring antibiotics and additional treatment.

Long-Term Prognosis

The long-term prognosis for dogs with laryngeal paralysis depends on the severity of the condition, the surgical technique used, and the patient's overall health. Dogs that undergo successful laryngeal paralysis surgery can typically expect to enjoy a good quality of life with minimal respiratory issues.

However, it is important to note that laryngeal paralysis is a progressive condition that can worsen over time. Regular follow-up examinations and monitoring are recommended to ensure that the dog's respiratory function remains adequate and that any necessary adjustments to treatment are made.
