title: Alteration in esophageal motility after laryngectomy.
abstract: Ten laryngectomees underwent esophageal motility studies to assess the effect of laryngectomy on esophageal function. When these patients are compared with controls, marked derangements in esophageal motility were noted in the upper esophageal sphincter (UES) and in the body of the esophagus. Lower esophageal sphincter (LES) function did not differ significantly from the controls. Dysphagia developed postoperatively in five of the ten laryngectomees. This preliminary analysis suggests that esophageal motility disturbances may be relatively frequent after laryngectomy and that these disturbances may be clinically significant. The theoretical basic for the motility abnormalities and areas of future research are discussed.
