Bolus volume has been widely studied, and research has demonstrated a variety of physiological impacts on swallowing and swallowing disorders. Oral perception of bolus volume has not, to our knowledge, been investigated in association with normal ageing processes. Research suggests many sensory changes with age, some within the oral cavity, and changes in swallowing function with age have been ...

Abstract The insula is a highly integrated cortical region both anatomically and functionally. It has been shown to have cognitive, social-emotional, gustatory, and sensorimotor functions. Insular involvement in both normal and abnormal swallowing behavior is well established, yet its functional connectivity is unclear. Studies of context-dependent connectivity, or the connectivity during diffe...

BACKGROUND Oropharyngeal dysphagia (OD) is a major complaint among many patients with neurological diseases and in the elderly, but is often underdiagnosed. The volume-viscosity swallow test (V-VST) is a bedside method to screen patients for dysphagia. METHODS The V-VST was designed to identify clinical signs of impaired efficacy (labial seal, oral and pharyngeal residue, and piecemeal deglut...

BACKGROUND Esophageal involvement by Chagas' disease causes a significative decrease in the number of neurons of the esophageal myenteric plexus, causing an impairment of esophageal motility with the same alterations described in primary esophageal achalasia. There is also a longer duration of pharyngeal transit, which might be consequent of the involvement of the central control of swallowing ...

OBJECTIVES The aim of this study was to investigate the direct effect of Facio-Oral Tract Therapy(®) on swallowing frequency of non-tracheotomised patients with acute neurogenic dysphagia. METHODS Within a pre-, post-/during and follow-up study design, 19 non-tracheotomised dysphagic patients were included consecutively and treated according to three specific preselected Facio-Oral Tract Ther...

An interim obturator prosthesis is required for the restoration of speech, deglutition, and improvement of esthetics after maxillectomy. This article describes a simple method for fabricating the interim obturator prosthesis by duplicating the patient's teeth and palate. The interim obturator prosthesis fabricated by duplication of the presurgical appearance and contour may be more acceptable t...

DOI: 10.5935/abc.20130137 Oropharyngeal dysphagia is a deglutition disorder resulting from neurological and/or structural impairment that may result in in decreased social interaction, loss of pleasure in food consumption, malnutrition, dehydration, infectious pulmonary processes and other high morbidity processes. Patients with heart disease from various causes present a risk of developing oro...
