Oropharyngeal dysphagia (OD) is an under-recognized condition that has been estimated to affect 30,000,000 Europeans over the age of 70 in 2012. The three main populations at risk for OD are the elderly, patients with neurological and neurodegenerative diseases, and patients with head and neck diseases. OD can lead to undernutrition, aspiration pneumonia and death. Thus diagnosis and management of OD are essential. This interactive e-learning course, that combines text, video and multiple-choice questions, describes the anatomy and physiology of normal and abnormal swallowing and the pathophysiological causes of OD. It then examines how to identify at-risk populations and diagnose OD via bedside screening, clinical evaluations and instrumental explorations. It next examines the complications of OD and the various treatment strategies currently available, including bolus modification, swallowing therapy and postural adjustment, among others. Management options are illustrated via case studies.
