Laryngeal reinnervation in the horse.
Abstract: Left laryngeal hemiplegia is a frustrating condition for the equine athlete and equine veterinarian. Treatment for the past 30 years has centered on the prosthetic laryngoplasty ("tie-back") with or without ventriculectomy. Laryngeal reinnervation has been used successfully in people and has been shown experimentally to benefit affected horses. This article reviews equine laryngeal reinnervation using the nerve muscle pedicle graft and describes the surgical technique, its complications, and the follow-up in 146 cases treated over the past 10 years. Also discussed is ongoing research into stimulation studies to improve the success of equine laryngeal reinnervation.

This research article investigates the use of laryngeal reinnervation, or nerve muscle pedicle grafts, as a treatment for left laryngeal hemiplegia in horses, discussing the methodology, potential complications, and outcomes based on a review of 146 cases over the past decade.
Understanding Left Laryngeal Hemiplegia
- Left laryngeal hemiplegia is a common condition in equine athletes, causing difficulty in breathing and consequentially, performance problems.
- The primary treatment for the last 30 years has been prosthetic laryngoplasty (also known as ‘tie-back’) which may be accompanied by ventriculectomy.
- Despite its commonality, it remains a troubling condition for both the horse and the veterinarian due to its impact on the horse’s quality of life and performance.
Laryngeal Reinnervation as a Treatment
- The article points out laryngeal reinnervation as another treatment option which has been successful in humans and may benefit horses as well.
- Laryngeal reinnervation involves using nerve muscle pedicle grafts to restore function in the affected area.
- Details of the surgical technique, its possible complications and the procedure’s success rate based on conducted cases are discussed in this research.
Outcomes from Past Cases
- The researchers review the results of 146 cases treated over the past 10 years to provide insights into the effectiveness and complications of the laryngeal reinnervation surgery.
- Though the abstract did not specify exact results, it suggests that the article contains in-depth analysis of these cases.
Ongoing Research
- Lastly, the research discusses ongoing studies aimed at improving the success rate of equine laryngeal reinnervation.
- Specifically, this involves studies on stimulation techniques that could potentially enhance the effectiveness of the surgery.
In summary, the article provides an in-depth review of laryngeal reinnervation surgery as a treatment for left laryngeal hemiplegia in horses, offering key insights from past cases and ongoing developments in the field.
