Presbyphagia is a term used to describe swallowing difficulty of the sort that can be associated with the aging process: the process of swallowing as a whole is inefficient and reduced in vigor. Common findings include globally (as opposed to focally) reduced muscle bulk, often seen in vocal cords and not just pharyngeal wall musculature; globally reduced strength of contraction of the pharynx; and tendency for retention or pooling of a part of swallowed food or liquid in the vallecula or pyriform sinuses. Presbyphagia may be associated with cricopharyngeal dysfunction and, when severe, aspiration.
