Which of the following is commonly identified as a normal, healthy change in swallowing function with old age?

• A. Nasal Regurgitation
• B. Slower Initiation of the Pharyngeal Response
• C. Stasis in the Vallecula
• D. Premature Opening of the Upper Esophageal Sphincter

Answer: (B)

As people age, some swallowing timing changes are common. A slower initiation of the pharyngeal response is frequently seen in healthy older adults and is considered a normal variation. This reflects a subtle slowing in sensory detection or reflex triggering of the pharyngeal phase once the bolus reaches the oropharynx. It may occur without compromising airway protection or overall safety, especially if there isn’t significant residue or penetration. By contrast, nasal regurgitation indicates inadequate velopharyngeal closure, vallecular stasis points to incomplete pharyngeal clearance, and premature opening of the upper esophageal sphincter shows mis-timed gateway opening—each signaling dysfunction rather than a normal aging change.
