OBJECTIVE: To quantitatively measure which dysphagic features, including
swallowing time and hyoid bone displacement, would be associated with increased
risk of aspiration pneumonia in dysphagic Parkinsonism patients. DESIGN: Clinical survey. SETTING: Tertiary care center. PARTICIPANTS: Patients with Parkinsonism
and dysphagia (N=25), referred for videofluoroscopic swallowing study, were
recruited by retrospective review of medical records. They were divided into 2
groups according to the history of aspiration pneumonia. INTERVENTIONS: Not
applicable. MAIN OUTCOME MEASURE: Swallowing time including onset of pharyngeal
swallowing, oral transit time and pharyngeal transit time, and maximum hyoid bone
displacement including total, horizontal, and vertical displacement during
swallowing in thin and thick bariums were recorded. RESULTS: Patients with
history of aspiration pneumonia had significantly longer pharyngeal transit time
(4.14 vs 2.31s, P=.038) and onset of pharyngeal swallowing (2.16 vs 1.04s,
P=.031) than those without, when swallowing thin barium. Patients with aspiration
pneumonia also had significantly longer swallowing time when swallowing thick
barium (oral transit time: 7.14 vs 2.33s, P=.018; pharyngeal transit time: 6.39
vs 1.23s, P=.004; onset of pharyngeal swallowing: 5.11 vs .31s, P=.006). There
was no significant difference in hyoid bone displacement between the 2 groups.
CONCLUSIONS: Patients with Parkinsonism dysphagia and aspiration pneumonia had
longer swallowing time than those without, but there was no difference in
displacement of hyoid bone.
