Tracheoesophageal puncture for voice restoration: modification of the Blom-Singer technique

We have used a modification of the Blom-Singer technique in our last 24 tracheoesophageal punctures, performed on 20 patients. At the time of puncture a surgical stent with an indwelling Dacron polyester suture is placed to form the fistula. Forty-eight to 72 hours later the stent is backed out of the puncture site but the suture is allowed to remain. The Blom-Singer duckbill prosthesis is fitted and taped in the routine fashion. The suture is left to traverse the tracheoesophageal tract until the time of discharge, when it is removed. At discharge the patient is given a Silastic dilator, to be used if the puncture site becomes too small to allow for insertion of the duckbill prosthesis. Seventeen of the 20 patients in this group obtained good voice. Six operations would have been failures because of the loss of the patient's prosthesis in the immediate postoperative period if the modified technique had not been used.
