Hypothesis
CFD analysis will corroborate the order of the different trials based on impedance and provide insights into airflow changes associated with each procedure.
Conclusion
The study found that partial arytenoidectomy had the lowest impedance, although the overall procedural order differed from previous studies.
Supporting Evidence
- Partial arytenoidectomy had the lowest impedance in the study.
- The CFD model reflected experimental findings for the procedure with the least impedance.
- Negative pressure concentration was observed on the left arytenoid cartilage in certain models.
Takeaway
This study looked at how different surgeries affect airflow in horses' throats using computer models, finding that one surgery worked best for airflow.
Methodology
An equine cadaver head underwent airflow testing and CT scans to replicate recurrent laryngeal neuropathy and four surgical procedures, with pressure and airflow data recorded for each trial.
Potential Biases
The use of cadaver tissue instead of live tissue may introduce biases in the results.
Limitations
The study used a single cadaver head, which may limit the generalizability of the results to other horses.
Participant Demographics
One equine cadaver head from a six-year-old Quarter Horse mare.
