Manometric Evaluation of Pediatric Swallow
Swallowing involves precise coordination of muscle contractions, resulting in pressure changes that act on oropharyngeal structures as well as the swallowed material. Pharyngeal manometry can measure some of these pressures through the use of a flexible pressure catheter placed transnasally through the pharynx and esophagus. This allows for the objective measurement of swallowing pressures, providing data not obtainable by other evaluation techniques and enabling for straightforward comparisons between healthy and disordered swallowing. This chapter explores indications, techniques, and data output of pharyngeal high-resolution manometry, with special considerations for the pediatric population. Published normative data and future directions for this field are also presented.
