Dysphagia other diagnostic studies
Introduction
Overview
Overview
Other diagnostic studies for dysphagia include esophageal manometry, electromyography, and electroglottograpghy.
Other Diagnostic Studies
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.{{#ev:youtube|795yXyvZaAs}}
Electromyography
- Electromyography has limited use clinically in diagnosing dysphagia.
- Two subtypes:
- Swallowing electromyography
- Laryngeal electromyography
