Oropharynx in patients with cerebrovascular disease: evaluation with videofluoroscopy.

Abstract

Forty-six patients with cerebrovascular disease underwent videofluoroscopic examination of the oropharynx to assess location and severity of swallowing dysfunction with use of boluses of various consistencies. Low- and high-viscosity barium suspensions, a barium paste, and a paste-coated cookie were used; not all patients were given all materials. Thirty-nine patients had abnormalities of both oral and pharyngeal function. Two patients had oral dysfunction only, and five had pharyngeal abnormalities only. Mild swallowing difficulties occurred in 18 patients (39%), moderate dysfunction in 23 (50%), and severe dysfunction in five (11%). Thirty-one patients had pharyngeal stasis, which was symmetric in 25 patients (81%), right-sided in three, and left-sided in three. Asymmetric stasis did not correlate to the site of cerebrovascular disease. Twenty-four episodes of aspiration occurred, half of them with the low-viscosity barium suspension. Thus, video-fluoroscopy can be used to define the location and severity of oropharyngeal abnormalities, which is critical for feeding recommendations. The abnormalities present, however, were not useful in predicting the type of cerebrovascular disease.

Normal Swallowing and Functional Magnetic Resonance Imaging: A Systematic Review

“…These investigations have characteristically started with a disordered neurologic group (i.e., poststroke population) and combined both anatomical brain-imaging techniques (still pictures of the brain) such as computerized tomography (CT) and/or magnetic resonance imaging (MRI) with a swallowing assessment to correlate damaged brain areas with the presence or type of dysphagia observed. The vast majority of clinical studies have focused on the effects of stroke on swallowing [2][3][4][5][6][7][8][9][10][11][12][13][14][15] This systematic review summarizes studies that have explored the neurophysiology of swallowing in healthy adults using fMRI. The goal of a systematic review is to gather and present objectively the current status of research in a particular area of interest.…”

Tempo de trânsito oral e lateralidade da lesão cerebral no acidente vascular encefálico

“…These studies included individuals with bilateral and brainstem injuries, which may have compromised the analysis between both hemispheres. Besides that, this comparative study used only qualitative analysis employing videofluoroscopy (24) . A relevant discussion on the importance of the quantitative analysis of swallowing has concentrated on the fact that changes in these measurements may be related to many pulmonary and nutritional risk predictors in this population.…”
