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
Video Fluoroscopic Swallowing Study
Video Fluoroscopic Swallowing Study(VFSS), also known as modified barium swallow, is used as the initial study for the evaluation of oropharyngeal dysphagia It provides the following information about the oropharyngeal swallowing mechanism: the inability or excessive delay in initiation of pharyngeal swallowing, aspiration of ingestate, nasopharyngeal regurgitation, and residue of ingestate within the pharyngeal cavity after swallowing
