Partial arytenoidectomy in 14 standing horses (2013-2017).
Abstract: To report our experience with partial arytenoidectomy in sedated standing horses. Methods: Retrospective study. Methods: Fourteen client-owned adult horses. Methods: The medical records (2013-2017) of horses treated with unilateral partial arytenoidectomy while standing and sedated were reviewed. Demographics, endoscopic findings, previous treatments, and outcome after surgery were investigated and recorded. Results: Thirteen horses had unilateral left-sided recurrent laryngeal neuropathy (RLN) and 1 horse had bilateral RLN. Five horses had a previous failed prosthetic laryngoplasty. Left-sided partial arytenoidectomy without mucosal closure was successfully completed in all horses under sedation and local anesthesia. Report of long-term outcome was obtained via telephone conversations for 12 horses, of which 9 also had an endoscopic reevaluation performed; 3 horses had granulomas at the surgical site, of which 2 eventually required a permanent tracheostomy. Nine horses returned to athletic use without respiratory noise, 2 horses returned to athletic use with noise during exercise that was reduced compared with preoperative levels, and 1 horse continued to be used as a broodmare. Conclusions: Partial arytenoidectomy in standing horses was achieved with adequate sedation and local anesthesia. Conclusions: Partial arytenoidectomy on standing sedated horses could be considered as an alternative to eliminate the risks associated with general anesthesia.

The research undertaken investigates the effectiveness of performing partial arytenoidectomies on sedated, standing horses. The results indicated it to be a viable alternative to the risks associated with general anesthesia.
Methodology
- This study is retrospective in nature.
- It involved 14 adult horses, all owned by clients.
- The researchers reviewed the medical records for these horses from the period of 2013-2017.
- All horses had been treated with a procedure called a unilateral partial arytenoidectomy, performed while the horse was standing and sedated.
- Data about the horse’s demographics, endoscopic findings before and after surgery, any previous treatment attempts, and the outcome post-surgery was recorded and analyzed.
Results
- Out of the 14 horses, 13 had a condition known as unilateral left-sided recurrent laryngeal neuropathy (RLN), while one horse suffered from RLN on both sides.
- Five of these horses had previously undergone an unsuccessful prosthetic laryngoplasty.
- All horses successfully underwent a left-sided partial arytenoidectomy without the closure of mucosal tissue. This was done under sedation and local anesthesia.
- Long-term outcomes were known for 12 horses, via telephone follow-ups. For nine of these horses, an endoscopic reevaluation was also performed.
- Occurrence of granulomas at the surgical site was found in three horses. Two of these horses eventually needed a permanent tracheostomy.
- Out of the 12 horses, nine were able to return to athletic use without any respiratory noise. Two horses did return to athletic use but displayed reduced noise during exercise compared to pre-surgery levels. One horse continued to be used as a broodmare after the surgery.
Conclusions
- The study concluded that partial arytenoidectomy in standing horses can be effectively performed under adequate sedation and local anesthesia.
- The researchers suggest considering this procedure as an alternative to more risky procedures requiring general anesthesia.
