What is Arytenoid Lateralization (Laryngeal Tie Back)?

Arytenoid lateralization, commonly referred to as “tie-back”, is a surgical procedure used to treat laryngeal paralysis in dogs. In this procedure, the arytenoid cartilage is repositioned to improve airflow through the larynx.

Indications:

1. Laryngeal Paralysis:
   • Dogs with laryngeal paralysis experience difficulty breathing due to inadequate opening of the larynx during inspiration.
   • Surgical intervention is indicated when the condition causes severe respiratory distress or exercise intolerance.

Procedure:

1. Surgical Technique:

   • The procedure involves creating a wider airway in the larynx by placing a suture between the cartilages of the larynx (arytenoid cartilages).
   • The goal is to hold the cartilages in an open position, allowing better airflow.
   • A small skin incision is made over the side of the throat region to access the larynx and allow placement of the suture.

2. Postoperative Care:

   • Close monitoring for signs of complications (swelling, bleeding, or altered breathing).
   • Most patients experience improved breathing and reduced respiratory distress.

Benefits:

1. Improved Airflow:
   • Arytenoid lateralization widens the airway, allowing easier breathing.
   • Noisy breathing and exercise intolerance are alleviated.
2. Enhanced Quality of Life:
   • Dogs can breathe more comfortably and engage in normal activities.

Remember that individual cases may vary, and consulting a veterinarian is essential for proper diagnosis and treatment.
