What best describes oropharyngeal dysphagia?

• A. Difficulty initiating swallowing due to the oral or pharyngeal phase
• B. Difficulty with esophageal peristalsis
• C. Reflux of gastric contents
• D. Passive expulsion of food

Answer: (A)

Oropharyngeal dysphagia occurs when the problem lies in moving the bolus from the mouth through the pharynx into the esophagus, due to weakness or discoordination of the oral and pharyngeal muscles and reflexes. The hallmark is difficulty initiating the swallow—the tongue and pharyngeal muscles fail to trigger a timely, coordinated swallow—often with coughing, choking, or nasal regurgitation as the bolus enters the airway. This highlights a disruption in the oral or pharyngeal phase, before the bolus reaches the esophagus.

In contrast, trouble with esophageal peristalsis describes a problem downstream in the esophagus, with sensations of food sticking, usually during or after the swallow and often affecting solids more than liquids. Reflux of gastric contents relates to GERD, not the initiation of swallowing. Passive expulsion of food suggests regurgitation without an active swallow, which is a different phenomenon from the initiation difficulty seen in oropharyngeal dysphagia.
