Tracheoesophageal shunt | definition of tracheoesophageal shunt by Medical dictionary
a surgical procedure to restore vocal function in patients who have had a laryngectomy by creating a tracheoesophageal fistula through which the laryngectomee forces air from the trachea into the esophagus to produce sound that is articulated into speech.
surgical formation of a passageway between the trachea and the esophagus that enables a laryngectomee to speak. The operation results in an ability to produce esophageal speech with normal respiration as a source of air and without the need to belch to produce voice sounds. Also spelled tracheooesophageal shunt.
