Variations in the application of equine prosthetic laryngoplasty: A survey of 128 equine surgeons.

Abstract: To document variations in the application of equine prosthetic laryngoplasty among equine surgeons. Methods: Cross-sectional survey. Methods: Six hundred and seventy-eight equine surgeons performing prosthetic laryngoplasty. Methods: An online questionnaire was sent to equine surgeons, including diplomates of the American College of Veterinary Surgeons and European College of Veterinary Surgeons. Questions focused on participant profile, surgical technique, antimicrobial therapy, and concurrent procedures. Descriptive statistical analysis was performed on the survey output. Results: Complete responses were received from 128/678 individuals, mostly from experienced surgeons. Most participants used 2 prostheses (106/128, 82.8%) and a single loop was the most common method used to anchor the prosthesis in the cricoid (95/128, 74.2%) and arytenoid (125/128, 97.7%) cartilages. Use of general anesthesia was common, although 46/128 (35.9%) participants now performed most laryngoplasty surgery with standing sedation. The material used as a prosthesis varied among surgeons, although participants typically aimed to achieve grade 2 intraoperative arytenoid abduction. Participants most commonly administered perioperative systemic antimicrobial therapy for 1-3 days (57/128, 44.5%) and 48/128 (37.5%) used local antimicrobial therapy. Conclusions: Most surgeons performed laryngoplasty with 2 prostheses, a single loop construct at the muscular process of the arytenoid cartilage and systemic antimicrobial therapy. There was variation in the preferred method of surgical restraint, prosthesis material selection, and use of local antimicrobial therapy. Conclusions: Long-established techniques remain popular in clinical practice despite evidence that variations offer advantages, particularly in relation to biomechanics. Other factors are also likely to influence technique selection in a clinical context.

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 study surveys the methods and variations employed by equine surgeons when performing prosthetic laryngoplasty, a common procedure to treat respiratory issues in horses. The research indicates that while most surgeons utilize similar techniques, some variations exist in areas such as surgical restraint, prosthesis material selection, and use of local antimicrobial therapy.

Research Methodology

  • The researchers conducted a cross-sectional survey of 678 equine surgeons who regularly perform prosthetic laryngoplasty. These surgeons included members of the American College of Veterinary Surgeons and Eurpoean College of Veterinary Surgeons.
  • The survey was distributed online and included questions about the surgeon’s profile, their surgical technique, their use of antimicrobial therapy, and any concurrent procedures they perform.
  • Descriptive statistical analysis was then performed on the collected survey data.

Survey Results

  • A total of 128 surgeons completed and returned the survey.
  • The results showed that most surgeons hosted two prostheses (82.8%) and preferred to use a single loop method to anchor the prosthesis in the cricoid (74.2%) and arytenoid (97.7%) cartilages.
  • General anesthesia was commonly used in these surgeries, but nearly 36% surgeons performed most laryngoplastys with the horse in standing sedation.
  • Prosthesis material varied among surgeons, with the aim typically being to achieve grade 2 intraoperative arytenoid abduction.
  • Over 44% of surgeons normally provide systemic antimicrobial therapy for 1-3 days after the operation. About 37.5% also used local antimicrobial therapy.

Conclusions

  • The survey concluded that while most surgeons follow similar methods for laryngoplasty, there are noted variances, particularly in the areas of surgical restraint, choice of prosthesis material, and use of antimicrobial therapy.
  • The research observed that long-established surgical techniques continue to be popular despite evidence that certain variations may bring advantages especially in terms of biomechanics.
  • Other factors that were not identified in this survey also likely influence technique selection in a clinical setting.
