Overview
Other diagnostic studies for dysphagia include esophageal manometry, electromyography, and electroglottograpghy.
Other Diagnostic Studies
Other diagnostics studies for dysphagia are as follows:[1][2]
- Electromyography (EMG)
- Electroglottography (EGG) (records vocal fold movement)
- Manometry
Esophageal manometry
Manometry is performed to assess motor function of the esophagus.
- High resolution manometry is recommended.
- Most commonly indicated for diagnosing esophageal dysphagia.
- Uses miniature, multichannel, water-perfused catheters or solid-state catheters
- Pressures gradients are recorded along the esophageal body and the gastroesophageal junction
- Computerized interpolation generates esophageal pressure isocontour lines.
- Facilitates differentiation between a restrictive disorder and muscular weakness in the pharyngoesophageal segment.
Electromyography
- Electromyography has limited use clinically in diagnosing dysphagia.
- Two subtypes:
- Swallowing electromyography
- Laryngeal electromyography
