Alaryngeal voice is usually accompanied by esophageal speech; however, about 40% of laryngectomy patients are unable to achieve adequate esophageal speech and must rely on mechanical devices for communication. A technique was developed for performing double-contrast studies of the hypopharynx, cervical esophagus, and pharyngo-esophageal segment using thick barium and the air normally injected for speech. Simultaneous audio and video recordings obtained during esophageal speech allowed correlation of the quality of speech with the motion of the pharyngo-esophageal segment. In 35 patients with various degrees of fluency in esophageal speech, normal and abnormal function of the pharyngo-esophageal segment was documented. Inadequate esophageal speech can be related to abnormal motion of the pharyngo-esophageal segment.
