A number of compensatory and rehabilitative strategies have been developed to facilitate and improve swallowing function in patient with dysphagia. Few data exist defining the effects of those techniques on neurophysiological measures of head and neck cancer patients who have undergone chemoradiation. The objective of this study was to determine the effects of head rotation and chin tuck on pharyngeal swallowing pressures and bolus flow in head and neck cancer patients. Nine head and neck cancer patients between the ages of49 and 76 who had received concurrent chemoradiation in the past 4 to 11 months served as participants. Simultaneous pharyngeal manometry and videofluoroscopy was performed using normal head position, head rotation to the right and left side, and chin tuck. Videomanometric data derived from these head and neck cancer patients indicate a head turn can increase upper pharyngeal pressures on the opposite side of the catheter and prolong UES relaxation. The chin tuck may be effective in generating decreased pharyngeal pressures and lower P-A scale scores for smaller volumes. Understanding the anatomical changes resulting from head rotation and chin tuck posture will provide valuable information for future treatment of head and neck cancer patients with swallowing disorders.
