 |
- Assessment of function of critical structures within the pharynx (throat)
- Assessment of saliva management
- Direct assessment of swallowing function for food and liquid
- Response to therapeutic maneuvers and interventions to improve the swallow
No fasting of sedation is required for this technique. As with the MBS, the examination can be recorded on video for further analysis.
