Excerpt
The oropharyngeal swallow involves a rapid, highly coordinated set of neuromuscular actions beginning with lip closure and terminating with opening of the upper esophageal sphincter. The central coordination of this complex sensorimotor task uses a widespread network of cortical, subcortical, and brainstem structures. Many diseases and disorders affecting the central swallowing network or downstream peripheral nerves, muscles, and structures may result in an impaired oropharyngeal swallow. In addition, aging is also associated with multifactorial changes of swallowing physiology for which the term presbyphagia has been coined. Oropharyngeal dysphagia broadly affects respiratory safety due to the increased risk of aspiration, and swallowing efficacy leading to the impeding danger of insufficient nutrition and hydration. …
