Using the larynx as a last resort for oral intake in a hypopharyngeal cancer patient.

We present a new oral intake route in a hypopharyngeal cancer patient with severe complications. A 64-year-old man was diagnosed as having T2N0M0 squamous cell carcinoma of the posterior wall of the hypopharynx. He had previously undergone radiotherapy for laryngeal cancer and tricuspid valve replacement surgery, and also had atrial flutter and renal dysfunction. We performed surgery with curative intent. The hypopharynx was primarily closed after tumor resection. Laryngotracheal separation and tracheoesophageal diversion with end-to-end anastomosis of the trachea to the esophagus was performed. After surgery, complete oral feeding was achieved using the new pathway created. The larynx, contradictory to its typical role, can be used as a pathway to the esophagus using our revolutionary technique.
