Swallowing of bolus types by postsurgical head and neck cancer patients.
BACKGROUND
Clinically, head and neck cancer patients with anterior resections have better postoperative outcomes than do patients with posterior resections.


METHODS
Videofluoroscopy was used to study the swallowing characteristics in postsurgery head and neck cancer patients and normal controls. Most patients received post-operative radiotherapy and chemotherapy, and no cancer recurrence was noted at the time of study, 4-8 months posttreatment. Bolus types included: 3 mL and 10 mL liquid barium, barium paste, and barium-coated cookie. Temporal measurements and a count of the number of swallows required to ingest each material were made from the videotaped data. Statistical analysis using an unbalanced univariate repeated measures ANOVA was performed.


RESULTS
The major differences were found between bolus types, with few differences noted between surgical groups (anterior vs posterior resections) and normal controls. Patients took longer to ingest viscous material, accomplishing this by multiple piecemeal and clearing swallows. Coordination of mastication and swallowing of the cookie was different between normal and patient groups.


CONCLUSIONS
Patients who are able to swallow reasonably well postoperatively maintain normal coordination and timing of swallowing activity and do not vary these parameters to compensate for structural inadequacy. Instead, repeated swallows are used.
