Swallowing is the process by which food is transported from the mouth to the stomach. Functionally, it may be divided into three phases—preparatory, transfer, and transport phases—that follow each other in a sequence. The preparatory phase includes conscious effort to ingest food and reflexes in the oral cavity that help the preparation of the bolus to be swallowed. The transfer phase involves reflex activities in the oral and pharyngeal passages. The transport phase includes transport of the swallowed food bolus through the esophagus into the stomach.

Swallowing disorders are common, especially in the elderly, and may cause dehydration, weight loss, aspiration pneumonia and airway obstruction. These disorders may affect the oral preparatory, oral propulsive, pharyngeal and/or esophageal phases of swallowing. Impaired swallowing, or dysphagia, may occur because of a wide variety of structural or functional conditions, including stroke, cancer, neurologic disease and gastroesophageal reflux disease. A thorough history and a careful physical examination are important in the diagnosis and treatment of swallowing disorders. The physical examination should include the neck, mouth, oropharynx and larynx, and a neurologic examination should also be performed. Supplemental studies are usually required. A videofluorographic swallowing study is particularly useful for identifying the pathophysiology of a swallowing disorder and for empirically testing therapeutic and compensatory techniques. Manometry and endoscopy may also be necessary. Disorders of oral and pharyngeal swallowing are usually amenable to rehabilitative measures, which may include dietary modification and training in specific swallowing techniques. Surgery is rarely indicated. In patients with severe disorders, it may be necessary to bypass the oral cavity and pharynx entirely and provide enteral or parenteral nutrition.

Dysphagia (difficulty in swallowing) is an important issue in the elderly because it causes aspiration pneumonia, which is the second largest cause of death in this group. It also causes decline in activities of daily living and quality of life. The oral phase of swallowing has been neglected, despite its importance in the evaluation of dysphagia, because adequate protocols and measuring devices are unavailable. However, recent advances in sensor technology have enabled straightforward, non-invasive measurement of the movement of important swallowing-related organs such as the lips and tongue, as well as the larynx. In this article, we report the present state and possibility of clinical application of such systems developed in Japan.
