BACKGROUND: This study examined the effects of @entity432 versus no occlusion on oropharyngeal swallowing in @entity135 @entity1 . METHODS: Eight treated @entity135 @entity1 were studied, six of whom had undergone surgical treatment for @entity5 and two who had undergone high-dose chemotherapy and radiotherapy for @entity5 . Videofluorographic studies of oropharyngeal swallowing were accomplished on 3-mL boluses of liquid in seven @entity1 and 3-mL boluses of paste in three @entity1 , first with the tracheostomy not occluded and then with it lightly digitally occluded by the @entity1 . Videofluorographic studies of swallow were examined for observations of @entity1173 and residue. Biomechanical analysis of each liquid swallow was also completed. RESULTS: Four of the seven @entity1 aspirated on thin liquids with the tube unoccluded. Aspiration was eliminated with the tracheostomy digitally occluded in two of these four @entity1 . One of the @entity1 also aspirated on paste with the tube unoccluded, and the @entity1173 was eliminated with the tube occluded. A third @entity1 who aspirated on thin liquid had no change when the tube was occluded, and one @entity1 's swallow worsened with the tube occluded on liquid. There were significant changes in five measures of swallow biomechanics on liquids with the tube occluded: (1) duration of base of tongue contact to the posterior pharyngeal wall was reduced, (2) maximal laryngeal elevation increased, (3) and (4) laryngeal and hyoid elevation at the time of initial cricopharyngeal opening increased, and (5) onset of anterior movement of the posterior pharyngeal wall relative to the onset of cricopharyngeal opening began later. CONCLUSION: Light @entity432 appears to be a safe procedure, because most biomechanics of swallow are positively affected, perhaps because of the increased resistance provided by the closed @entity825 . However, not all @entity1 received benefit from tube occlusion, indicating that each @entity1 must be evaluated individually to determine whether or not tube occlusion improves their swallow.
