Functional oropharyngeal sensory disruption interferes with the cortical control of swallowing

Abstract: BackgroundSensory input is crucial to the initiation and modulation of swallowing. From a clinical point of view, oropharyngeal sensory deficits have been shown to be an important cause of dysphagia and aspiration in stroke patients. In the present study we therefore investigated effects of functional oropharyngeal disruption on the cortical control of swallowing. We employed whole-head MEG to study cortical activity during self-paced volitional swallowing with and without topical oropharyngeal anesthesia in t… Show more

“…The water swallow test is inexpensive, ease to perform and give a good idea of the dynamic of ingestion. It does not give an idea of the oral, pharyngeal or esophageal phases of the swallow, but a results of all process of swallowing (1,3,5,6,13,29) . The test was able to demonstrate that there is a similar impairment, in terms of difficult for patients to ingest liquid, of water ingestion postfundoplication as seen in achalasia.…”

“…Estudos recentes com anestesia da orofaringe sugerem que os receptores sensoriais, encontrados na mucosa da orofaringe, são importantes para eliciar a deglutição e que a ausência ou disfunção destes contribuem para a disfunção da deglutição (Chee et al, 2005;Teismann et al, 2007;Ertekin et al, 2000;Yagi et al 2008). Como resultado desta disfunção tem-se a diminuição da velocidade e da capacidade de deglutição (redução do volume deglutido) (Chee et al, 2005;Teismann et al, 2007), podendo, ainda, em algumas vezes, resultar em aspiração laringo-traqueal (Ertekin et al 2000).…”
