Oral-pharyngeal dysphagia is a common problem with a high morbidity and mortality. In general, it is not managed as well as esophageal dysphagia by gastroenterologists. A number of techniques are now available for the assessment of oral-pharyngeal dysphagia. However, a careful clinical assessment followed by a video barium swallow is all that is required for the diagnosis and management in the majority of patients. Pharyngeal manometry is likely to play an increasingly important role in the assessment of difficult or atypical cases in whom it can provide functional information not achievable with videoradiography alone. Videolaryngoscopy is a quick and simple way of detecting structural lesions and of assessing deglutitive airway protection. Videolaryngoscopy is non-invasive and easily performed in an office setting. Ultrasonography is a convenient way of assessing lingual function, but provides no more information than the video barium swallow. Pharyngeal scintigraphy is likely to assume a greater clinical relevance as a means of quantifying swallow efficiency and response to therapy.
