Management of traumatic tracheoesophageal fistula.

Traumatic injury to the trachea most commonly results in separation of the trachea from the cricoid cartillage. In severe cases, this injury is complicated by an esophageal injury that is seriously complicated by a tracheoesophageal fistula. The repair of such a fistula is a prime priority. Surgical repair of the tracheal injury must be associated with esophageal repair and this is best accomplished by the interposition of the sternothyroid muscles between the trachea and the esophagus to strengthen the esophageal repair. The use of a laryngeal drop will also be of value in relieving the tension on the esophageal suture.

New techniques for vocal rehabilitation.

Following laryngectomy only 40 per cent of patients are able to attain esophageal speech. Several surgical and nonsurgical methods have been devised to solve this problem, but non is fully satisfactory. This paper describes two different experimental apporaches to the problem. A segment of trachea is isolated with an intact blood supply and anastomosed to the skin and esophagus, thus producing a fistula where the characteristic of the tracheo-esophageal junction can be studied. Efforts to implant a valve into this fistula have been unsuccessful but the fistula alone is patent after one year. The isolated tracheal segment provides an ideal model for study in an untracheatomized animal. In the second approach an electromagnetic sound device is being devised which can be implanted in the neck as near as possible to the previous site of the larynx. The results have been encouraging.
