Abstract
El esfínter esofágico superior (EES) es una zona de alta presión que se encuentra en la parte inferior de la faringe y protege la via aérea de la entrada de contenido esofágico. Se compone del músculo constrictor inferior de la faringe (que a su vez consta de los músculos cricofaríngeo y tirofaríngeo) y del esófago cervical. El EES se compone de fibras de músculo estriado distribuidas en dos zonas: la zona de fibras oblicuas de contracción rápida correspondiente al músculo tirofaríngeo; y la zona de fibras dispuestas horizontalmente, de contracción rápida pero sobre todo lenta, que pertenecen al músculo cricofaríngeo. De esta manera, el EES puede mantener un tono basal constante pero a la vez relajarse rápidamente en respuesta a determinados reflejos. Existen áreas supra e infratentoriales relacionadas con el proceso de deglución que influyen en la motilidad del esfínter esofágico superior...
Upper esophageal sphincter (UES) is a high pressure zone located at the bottom of the pharynx and protects the airway from the entrance of esophageal content. It is constituted by the inferior constrictor muscle of the pharynx (which is composed of thyropharyngeal and cricopharyngeal muscles) and cervical esophagus. UES consists on striated muscle fibers distributed in two zones: rapid twich oblique fibers correspondent to tyropharyngeal muscle and rapid but mostly slow twich horizontal fibers belonging to cricopharyngeal muscle. This permits UES maintain a constant basal tone and respond quickly to reflexes. Supratentorial and infratentorial areas are implicated in swallowing process and influence on upper esophageal sphincter motility. ..
