- To compare normal versus impaired laryngeal airway protection.
- To enhance understanding of the pathophysiology of neurological diseases.
Methods Used
- Injection of glycopyrrolate into anesthetized rodents.
- Serial transoral laryngoscopy for video imaging.
- Longitudinal examination of laryngeal function.
- Assessment of airway protection mechanisms.
Main Results
- Detailed imaging of laryngeal function during different phases.
- Ability to track changes over the course of disease.
- Insights into treatment mechanisms for laryngeal dysfunction.
- Potential for improved understanding of neurological disease impacts.
Conclusions
- This protocol enables comprehensive assessment of laryngeal function.
- It provides a valuable tool for studying neurological diseases.
