Management of postoperative dysphagia after prosthetic laryngoplasty or arytenoidectomy.

Abstract: To evaluate the efficacy of various treatments for dysphagia after laryngeal surgery. Methods: Retrospective. Methods: Horses treated for dysphagia after laryngeal surgery. Methods: Medical records of horses treated for dysphagia after prosthetic laryngoplasty (PLP) or partial arytenoidectomy (PA) were reviewed. Signalment, prior surgery, preoperative videoendoscopic diagnosis, and surgical treatments were recorded. Short- and long-term follow-up were obtained. Chi-square and logistical regression were performed to correlate independent variables and outcomes. Results: Forty-four percent of horses with prior PLP and 88% of horses with prior PA had persistent resting dorsal displacement of the soft palate (DDSP). Vocal fold augmentation (VFA) as a single treatment was most commonly performed (n = 22), followed by laryngoplasty removal (LPR; n = 1). Fifteen horses received a combination of treatments: VFA (n = 15), LPR (n = 4), laryngeal tie-forward (LTF; n = 2), and esophageal release (n = 1). Short-term clinical outcomes were reported; 80% of horses treated with VFA (n = 35) had resolution of dysphagia, and 20% were improved. Among the 33 horses available to long-term follow-up, 31 (94%) returned to some level of work, and DDSP during work was reportedly resolved in 23 of 25 horses. Conclusions: Vocal fold augmentation resulted in resolution of symptoms relating to dysphagia in 81% of horses. Twenty percent of horses treated with LPR had sustained resolution of dysphagia. A combination of LPR, VFA, LTF was performed in 18% of horses. Conclusions: Treatment options directed at altering laryngeal geometry and/or position of the larynx were successful in resolving 86% of dysphagia in horses previously regarded as very difficult to treat.

This research work assesses the effectiveness of different techniques in treating dysphagia (difficulty swallowing) after laryngeal surgery in horses.

Objective and Methodology

  • This is a retrospective study that evaluated the medical records of horses that had been treated for dysphagia following two types of laryngeal surgery: prosthetic laryngoplasty (PLP) and partial arytenoidectomy (PA).
  • The details compiled from the horse records included their specific characteristics, previous surgical history, preoperative videoendoscopic diagnoses, and the surgical treatments they received.
  • The study followed up both in the short term and the long term.
  • Statistical methods used for this research were Chi-square and logistical regression. These methods were designed to find correlations between different independent variables and achieved outcomes.

Results

  • The study found that 44% of horses with previous PLP and 88% with previous PA treatment displayed continued dorsal displacement of the soft palate (DDSP) during rest.
  • The most common single treatment executed was Vocal Fold Augmentation (VFA), performed on 22 horses. Only one horse received Laryngealplasty Removal (LPR) treatment.
  • There were 15 horses treated using a combination of methods: VFA, LPR, Laryngeal Tie-Forward (LTF), and Esophageal Release.
  • In the short term, 80% of the horses treated with VFA noticed an improvement in dysphagia and 20% showed a partial improvement.
  • In the long term, out of the 33 horses available for follow-up, 94% (31 horses) returned to some level of work. DDSP during work was reportedly resolved in 23 of 25 horses.

Conclusion

  • Vocal fold augmentation resulted in the resolution of dysphagia-related symptoms in 81% of the treated horses.
  • 20% of the horses that underwent LPR showed a sustained resolution of dysphagia.
  • Combination of treatments, including LPR, VFA, and LTF were performed in 18% of horses.
  • In total, treatments that focused on changing the laryngeal geometry and/or the location of the larynx were successful in addressing 86% of dysphagia in horses considered difficult to treat in previous studies.
