Ceratohyoidectomy in standing sedated horses.

Abstract: To investigate the feasibility and complications associated with ceratohyoidectomy (CHE) in standing sedated horses unaffected (experimental horses) and standing sedated horses affected (clinical cases) with temporohyoid osteoarthropathy (THO). Methods: Case series. Methods: Six experimental horses and four clinical cases. Methods: Standing CHE was performed in six experimental horses euthanized 30 minutes (n = 3) and 7 days (n = 3) postoperatively. The four clinical cases were presented because of central facial nerve paralysis (n = 3), vestibular ataxia (n = 3), auricular hemorrhage (n = 2), quidding (n = 1), and oesophageal impaction (n = 1). Evolution was assessed by clinical examination during hospitalization and later by telephone interviews for the clinical cases. Results: The procedure was successfully performed in all horses. Experimental horses did not show any short-term postoperative complications. Hemorrhage was experienced intraoperatively in one of the clinical cases and was successfully managed with placement of hemostatic forceps. Vestibular ataxia and other symptoms of THO improved within days, but facial nerve paralysis did not improve until 9 days to 6 months after surgery. Follow-up ranged from 9 to 24 months. All clinical cases returned to performance, and client satisfaction was excellent. Conclusions: Ceratohyoidectomy was consistently feasible in standing sedated horses. The method did not result in postoperative complications and led to resolution of clinical signs associated with THO. Conclusions: Standing CHE should be considered in horses affected with THO, especially when horses present with marked vestibular deficits and ataxia, to reduce risks associated with recovery from general anesthesia.

This research article investigates the effectiveness and potential complications of ceratohyoidectomy in horses, a procedure performed while the animals are sedated but standing. The researchers conclude that the operation is consistently feasible and can help resolve symptoms associated with temporohyoid osteoarthropathy.

Research Background and Methods

  • This research was conducted to explore the possibility and complications related to ceratohyoidectomy (CHE), a surgical procedure, in standing but sedated horses. The procedure involves removing, partially or entirely, the ceratohyoid bone that is part of the horse’s hyoid apparatus.
  • The study was specifically focused on horses unaffected (experimental horses) and horses diagnosed with temporohyoid osteoarthropathy (THO), a disorder affecting a horse’s temporohyoid joint.
  • For the research, a case series was conducted where standing CHE was carried out on six experimental horses. These horses then had to be euthanized after 30 minutes (three horses) or seven days (three horses) post-surgery.
  • On the other hand, four equine clinical cases were chosen that manifested symptoms like central facial nerve paralysis, vestibular ataxia, auricular hemorrhage, quidding, and oesophageal impaction. The progression or evolution of these cases was monitored through clinical examinations during hospitalization and later follow-ups via telephone.

Findings and Conclusion

  • The CHE operation was successfully conducted on all horses. Lack of any short-term postoperative complications was observed in the experimental horses.
  • Complications like intraoperative hemorrhage were noted in one clinical case, however, it was managed effectively using hemostatic forceps.
  • Improvements were noted in symptoms like vestibular ataxia within a few days, but facial nerve paralysis took longer, from 9 days to as long as 6 months to show improvement after surgery.
  • All the clinical horses returned to performance, and the feedback from their owners was excellent.
  • The research concludes that CHE can be performed consistently on standing, sedated horses without resultant postoperative complications and can also help in alleviating symptoms associated with THO. Therefore, standing CHE is recommended for those horses which are affected by THO, especially when they display noticeable vestibular deficits and ataxia. This is to reduce potential risks related to recovery from general anesthesia.
