Abstract:

Abstract Traumatic brain injury is the first cause of death in persons younger than 45 years in Spain . Swallowing disorders are common in the initial phase of a severe traumatic brain injury . The incidence of dysphagia varies between 25 and 61% of patients and the prognosis depends on correct evaluation and early and appropriate treatment . The outcome of dysphagia depends on a low score in the Rancho Los Amigos Cognitive Scale and the Glasgow Coma Scale , orotracheal intubation and the presence of tracheostomy . The most widely used instrumental assessment tool for the diagnosis of dysphagia is videofluoroscopy . This procedure consists of swallowing a variety of liquids and foods mixed with barium . Swallowing maneuvres and oral motor exercises are useful in the rehabilitation of swallowing . Functional magnetic resonance imaging of the brain shows the cortical areas that are activated during the application of rehabilitation treatment .
