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

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.^[3]^[4]^[5]

It provides the following information about the oropharyngeal swallowing mechanism:

Delay in initiation of pharyngeal swallowing
Nasopharyngeal regurgitation
Residue of ingestate within the pharyngeal cavity after swallowing
Aspiration of ingestate

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
