Laryngeal tie-forward in standing sedated horses.

Abstract: To investigate the feasibility and describe the clinical experience of performing laryngeal tie-forward (LTF) in standing horses unaffected (experimental) and affected (clinical) by intermittent dorsal displacement of the soft palate (iDDSP). Methods: Experimental study and case series. Methods: Five normal experimental controls and five client owned horses affected by iDDSP. Methods: Standing LTF was performed and evaluated in five experimental horses and five clinical cases diagnosed with iDDSP. Standing LTF was performed under endoscopic guidance with horses sedated and the surgical site desensitized with local anesthetic solution. Short term outcome was assessed using radiography, resting and (in clinical cases) dynamic upper respiratory tract (URT) endoscopy. Results: Standing LTF was well tolerated and completed in all horses. Radiographic assessment demonstrated that compared to preoperatively, the basihyoid bone and thyrohyoid-thyroid articulation were positioned dorsally (9.6 mm, p = .006 and 20.4 mm, p = .007, respectively) at 2 days postoperatively. During repeat dynamic URT endoscopy at 48 hours postoperatively, 3/5 horses showed resolution of iDDSP and 2/5 marked improvement. One horse experienced brief iDDSP associated with neck flexion which corrected after swallowing. The second achieved a greater speed and total distance prior to iDDSP. Conclusions: Standing LTF did not incur any major peri- or postoperative complications. The laryngohyoid apparatus was repositioned dorsally and in a small case series had a similar surgical effect on laryngeal position. Conclusions: Standing LTF is feasible, mitigates the risk of general anesthesia related complications and reduces cost.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research article investigates the effectiveness of performing a laryngeal tie-forward (LTF) procedure on horses, both normal and those affected by intermittent dorsal displacement of the soft palate (iDDSP), while they are standing. The study finds this method to be a feasible and cost-effective method for treating iDDSP in horses without the complications associated with general anesthesia.

Research Design and Methods

  • The study was structured as an experimental study and case series, involving five normal horses (experimental controls), and five client-owned horses diagnosed with iDDSP (clinical cases).
  • The LTF surgery was performed on all standing horses under endoscopic guidance, with the horses being sedated and the surgical site numbed with a local anesthetic solution.
  • Outcomes in the short term were evaluated using radiographic imaging as well as resting and dynamic upper respiratory tract (URT) endoscopy in clinical cases.

Results and Findings

  • The results showed that the standing LTF was well tolerated and successfully completed in all the horses.
  • Through radiographic assessment post-surgery, it was noted that the basihyoid bone and the thyrohyoid-thyroid joint had positioned dorsally, indicating a successful operation.
  • In the follow-up URT endoscopy conducted 48 hours after the surgery, 3 out of 5 horses had no more iDDSP, and 2 had a marked improvement. One horse displayed brief iDDSP during neck flexion, which was automatically corrected after swallowing, and another achieved a greater speed and distance before iDDSP occurred.
  • No major perioperative or postoperative complications were reported.

Conclusions

  • The study concluded that standing LTF is a feasible method for treating iDDSP in horses.
  • This surgical practice did not result in any major complications after surgery and proved to have a favorable impact on laryngeal position.
  • Additionally, standing LTF mitigated the risks associated with general anesthesia complications and was found to be cost-effective.
