Pharyngeal Swallowing

The effect of radiation on speech and swallowing function was assessed for 18 patients surgically treated for oral and oropharyngeal cancer. Nine patients received surgical intervention and postoperative radiation therapy, and nine received surgery only. Patients were matched regarding percentage of oral tongue resected, percentage of tongue base resected, locus of resection, and method of reconstruction. Speech and swallowing function was assessed before and at 1, 3, 6, and 12 months after surgery following a standardized protocol. Speech tasks included an audio recording of a brief conversation and of a standard articulation test; swallowing function was examined with videofluoroscopy. Statistical testing indicated that overall speech function did not differ between the irradiated and nonirradiated patients. Irradiated patients had significantly reduced oral and pharyngeal swallowing performance, specifically, longer oral transit times on paste boluses, lower oropharyngeal swallow efficiency, increased pharyngeal residue, and reduced cricopharyngeal opening duration. Impaired function may be the result of radiation effects such as edema, fibrosis, and reduced salivary flow. Increased use of tongue range-of-motion exercises during and after radiation treatment may reduce the formation of fibrotic tissue in the oral cavity and may improve pharyngeal clearance by maintaining adequate tongue base-to-pharyngeal wall contact.

Pharyngeal Clearance

The aim of the study was to determine the influence of normal aging on regional transit and the efficiency of bolus clearance during the oral and pharyngeal phases of swallowing. We compared scintigraphically derived oral-pharyngeal transit times and isotope clearance during swallowing in 21 healthy aged volunteers (mean age 68 +/- 8 yr) and 9 young controls (mean age 28 +/- 7.5 yr). Subjects swallowed 5- and 10-ml water boluses mixed with 30 MBq 99mtechnetium tin colloid. Oral and pharyngeal transit times, pharyngeal clearance time, and postswallow residual counts in each region were derived from time-activity curves. Pharyngeal residual counts were significantly greater in the aged than in controls (P = 0.0008), but age did not influence oral residual. Aging significantly prolonged oral transit time (P = 0.02), pharyngeal transit time (P = 0.0004), and pharyngeal clearance time (P = 0.0001). We conclude that normal impairs the efficiency of pharyngeal clearance during swallowing, prolongs scintigraphic measures of oral-pharyngeal transit, and increases the exposure time of the glottis to the swallowed bolus.

Pharyngeal Function

This study quantified the effects of head rotation on pharyngeal swallowing in healthy subjects. Videofluoroscopic and oropharyngeal manometric examinations of pharyngeal swallowing were performed on seven volunteers with the head in neutral and rotated positions. Videofluoroscopic study revealed that head rotation swallow causes the bolus to lateralize away from the direction of head rotation. Pharyngeal manometric study indicated that the pharyngeal peak pressures toward the side of head rotation were significantly increased, whereas the pharyngeal pressures opposite the side of head rotation were not affected. Head rotation swallow produced a significant fall in upper esophageal sphincter (UES) resting pressure and a delay in UES closing. We concluded that the head rotation swallow in normal subjects not only alters the bolus pathway, but also has a useful effect on both pharyngeal clearance and UES dynamics.
