Summary
The laryngeal tie-forward procedure (LTFP) effectively restores racing performance in horses with dorsal displacement of the soft palate (DDSP). Post-operative race earnings return to baseline levels, comparable to controls.
Area of Science:
- Equine surgery
- Equine performance science
Background:
- The laryngeal tie-forward procedure (LTFP) is increasingly used for dorsal displacement of the soft palate (DDSP) in racehorses.
- Evidence-based assessment of LTFP efficacy is lacking.
Purpose of the Study:
- To evaluate the efficacy of the LTFP in restoring race performance in horses with DDSP.
- To determine the association between post-operative laryngohyoid position and racing performance.
Main Methods:
- A case-controlled study involving 106 racehorses (36 definitive DDSP, 70 presumptive DDSP) undergoing LTFP.
- Race performance (starts, earnings) and radiographic laryngohyoid position (pre- and post-operative) were assessed.
- Horses were matched by age, breed, and sex to controls.
Main Results:
- Horses treated with LTFP were as likely to race post-operatively as controls.
- Race earnings were significantly lower before surgery but restored to baseline and control levels post-surgery.
- A more dorsal post-operative basihyoid and laryngeal position correlated with increased likelihood of racing.
Conclusions:
- The LTFP is an effective surgical procedure for DDSP in racehorses, restoring performance to preoperative and control levels.
- The study provides strong evidence supporting LTFP use in racehorses.
- Further research is needed on laryngohyoid conformation and nasopharyngeal stability.

01:21Larynx
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...

01:30Cardiopulmonary Resuscitation V: Advanced Airway Management Techniques
Airway management is essential in emergency and surgical medicine, ensuring ventilation and oxygenation in patients who cannot maintain their own airway. Clinicians use a range of techniques and devices to secure the airway, depending on the patient’s condition and the clinical context. Key methods include endotracheal intubation, rapid sequence intubation (RSI), supraglottic airway devices, and advanced visualization aids. In cases where these approaches fail, surgical airway interventions are...
