Computed tomographic features of the temporomandibular joint in 10 Jeju horses.

Abstract: The equine temporomandibular joint (TMJ) has a complex anatomical structure that makes diagnosis of TMJ disorders difficult. Computed tomography (CT) is now available in equine medicine; hence, TMJ evaluation has become more convenient. Objective: The objectives of this study were to describe the CT features of the TMJ in Jeju horses and to compare these features with those of Thoroughbreds. Methods: In this report, the TMJs of 10 Jeju horses (mean age: 4.5 ± 1.9 yr; mean body weight: 282.6 ± 40.3 kg) and 6 Thoroughbreds (mean age: 7.3 ± 1.6 yr; mean body weight: 479.7 ± 44.0 kg) were examined using CT. After CT scanning, the Hounsfield units (HU) and height to width ratio (H:W) of the mandibular condyle were measured. Results: The mean H:W in Jeju horses was significantly lower than that in Thoroughbreds. The mean HU in Jeju horses was lower than that in Thoroughbreds; however, the difference was not significant. The most frequent CT finding was an irregular medial margin of the mandibular condyle in both breeds. Conclusions: In this study, the shape of the mandibular condyle in Jeju horses was flatter than that in Thoroughbreds. This report could be useful in evaluating the TMJ in Jeju horses. Moreover, CT could be a pragmatic choice for the examination of the TMJ in horses.

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 paper studies the features of the Temporomandibular joint (TMJ) in Jeju horses using computed tomography (CT). It compares these features with those of Thoroughbred horses, finding that the CT features of the Jeju horses’ TMJ are distinct, possibly aiding further studies and diagnosis of TMJ disorders in these animals.

Objective of the Study

  • The purpose of this study is to describe and understand the computed tomographic (CT) features of the Temporomandibular joint (TMJ) in Jeju horses, a breed specific to the Jeju island in South Korea.
  • The study also aims to compare these features with those of Thoroughbreds, helping diagnose any potential TMJ disorders in horses more accurately.

Methodology

  • In the process of the research, the TMJs of 10 Jeju horses and 6 Thoroughbreds were examined using CT scanning.
  • The researchers collected additional data that could influence the results, such as the average age and average body weight of the horses from both breeds.
  • Post scanning, measurements of Hounsfield units (HU) and the height to width ratio (H:W) of the mandibular condyle were taken. The Hounsfield unit is a measure of radiodensity while the H:W ratio provides an idea of the shape of the mandibular condyle.

Results of the Study

  • The results indicated that the H:W ratio in Jeju horses was significantly lower than in Thoroughbreds, suggesting a difference in the shape of the mandibular condyle between the breeds.
  • The HU in Jeju horses was also lower than that in Thoroughbreds. However, this difference was not statistically significant.
  • One common finding across both breeds was an irregular medial margin of the mandibular condyle.

Conclusion

  • The research concludes that the shape of the mandibular condyle in Jeju horses is flatter compared to that in Thoroughbreds.
  • This study provides valuable insights for evaluating TMJ in Jeju horses, aiding the potential diagnosis of TMJ disorders.
  • It also strengthens the case for using CT as a practical choice for the examination of the TMJ in horses, given its ability to provide intricate details about the complex anatomical structure.
