Total laryngectomy or laryngopharyngectomy are commonly performed for the treatment of laryngeal cancer or hypopharyngeal cancer. However pharyngocutaneous fistula and cervical esophageal stenosis have been reported as postoperative complications of these procedures. We used a silicon pharyngeal tube in cases that developed pharyngocutaneous fistula and cervical esophageal stenosis. The pharyngeal tube was useful for controlling aspiration pneumonia and for starting oral feeding in a case of pharyngocutaneous fistula after a total laryngectomy. It was also helpful for starting oral feeding in a case with cervical esophageal stenosis after total laryngopharyngectomy and free jejunum interposition. This patient was able to maintain a good quality of life until re-operation. Adverse effects from the insertion of the tube included a foreign body sensation and pharyngeal pain that was tolerable with the use of NSAIDs for a short time. Silicon pharyngeal tubes are useful for the treatment of pharyngocutaneous fistula and cervical esophageal stenosis.
