Summary
# Editorial Summary: Modified Laryngeal Tie-Forward Procedure Using Metallic Implants Dorsal displacement of the soft palate (DDSP) remains a significant performance-limiting condition in racehorses, and whilst traditional laryngeal tie-forward procedures (LTFP) are well-established, the original technique carries inherent risks of suture failure. Rossignol and colleagues investigated whether incorporating metallic Suture Button™ implants and a modified single-knot tying technique could improve surgical outcomes in 27 horses (predominantly racehorses) with DDSP or palatal instability diagnosed via high-speed treadmill endoscopy, resting examination, or dynamic over-ground endoscopy. All procedures were completed without intraoperative complications, with postoperative radiographs confirming secure positioning of the three metallic buttons and no evidence of suture breakage at 24 hours. Whilst the core surgical principles remain unchanged from the original Ducharme technique, the metallic implants appear to distribute load more effectively across the thyroid cartilage, potentially reducing suture pull-through—a common failure mode. For equine practitioners, this modification represents a pragmatic refinement that warrants consideration, particularly given the critical importance of surgical durability in high-performance horses where palatal displacement recurrence directly impacts athletic careers.

Practical Takeaways
- •This modified LTFP using metallic implants provides improved visualization and potential mechanical advantage for securing sutures during DDSP/PI correction.
- •The technique appears safe with no reported complications in this case series, though long-term follow-up data on return to performance are limited to telephone communication.
- •Surgeons considering this modification should be aware it requires different equipment (Suture Buttons) and modified tying technique versus traditional LTFP.
Key Findings
- •Modified laryngeal tie-forward procedure using metallic Suture Button implants was performed without surgical complications in 27 horses (24 racehorses).
- •Metallic buttons were clearly visible on postoperative radiographs and no suture breakage was observed 24 hours post-surgery.
- •Technique may offer increased suture resistance to pullout from thyroid cartilage compared to original procedure.
- •Return to performance expected to be similar to original laryngeal tie-forward technique.
