Other Diagnostic Studies
Other diagnostics studies for dysphagia are as follows:[1][2]
Oropharyngeal Dysphagia
- Videofloroscopic Swallowing Study
- Electromyography (EMG)
- Electroglottography (EGG) (records vocal fold movement)
- Pharyngeal manometry
Esophageal Dysphagia
- Esophageal manometry
- High resolution manometry
- Uses miniature, multichannel, water-perfused catheters or solid-state catheters
- Pressures are recorded along the esophageal body and across the gastroesophageal junction
- Computerized interpolation generates esophageal pressure isocontour lines
- Facilitates differentiation between a restrictive disorder and muscular weakness in the pharyngoesophageal segment
- High resolution manometry
