Effects of voluntary maneuvers on tongue base function for swallowing.
Concurrent manometry and videofluoroscopy were utilized to examine tongue base function during swallowing in 3 patients with head and neck cancer. Subjects were instructed in four voluntary swallow maneuvers, including the supersupraglottic swallow, effortful swallow, Mendelsohn maneuver, and tongue-hold maneuver. Peak catheter pressures (mm Hg) at the tongue base-pharyngeal wall level were recorded and duration of tongue base to pharyngeal wall contact was measured for each swallow. This pilot study revealed that tongue base-pharyngeal wall pressures and contact duration increased with use of maneuvers. Preliminary data are provided to support the use of swallow maneuvers to improve tongue base posterior motion and pressures generated at the tongue base-pharyngeal wall level during swallowing in patients who exhibit this disorder.
