[Long-term results of one stage tracheoesophageal end-side anastomosis voice restoration after total laryngectomy].

OBJECTIVE

The purpose of this study is to discuss long-term results of one different kind of voice restoration after total laryngectomy with 10 years experience.

METHOD

One stage tracheoesophageal end-side anastomosis after total laryngectomy was performed in 36 patients from 1991-1996. The key technique of this operation is to make a tongue-ship flap(1.5 cm x 1.5 cm-1.8 cm x 1.5 cm) with tracheal membranous part and dissect it from the esophagus to 1 cm below the upper incisal margin of trachea. Then a 0.8 cm middle vertical incision was made on the lowest anterior wall of the separated esophagus. Folding the tongue-ship flap posteriorly to approximate the esophagus incision and make an end-side anastomosis. Close the upper incisal margin of trachea with left to right direction suture. The follow up time is 5 - 10 year. One lost follow 2.5 years later and was judged as dead.

RESULT

The short-term and long-term success rate were 69% (25/36) and 83% (30/36) respectively. The 3-, 5- and 10 year survival rate are 72%, 69%, 69%, respectively.

CONCLUSION

This technique does not change the pattern of total laryngectomy and various neck dissections do not affect voice rehabilitation. Advantages of the operation: easy to operate and learn; the special form of tracheoesophageal shunt (high in the tracheal side and low in esophageal side) prevents the aspiration; high successful rate, excellent speech, fluent language, good acceptability and lower aspiration.
