[Vocal restoration by tracheo-esophageal fistula. Evaluation of a 5 years' experience].

Between december 1985 and august 1990, 70 patients with total laryngectomy had their voice restaured by creation of tracheo-esophageal fistula. The tracheo-esophageal fistula was created during laryngectomy in 33 cases (20 punctures with Blom Singer prostheses, 13 surgical shunts), a few weeks later after surgery of radiotherapy in 17 cases or when production of esophageal voice feld in 20 cases. No major complication was observed. Results following voice recovery were satisfactory in 78.5% of cases (normal voice), one month after the procedure. Results are better when tracheo-oesophageal fistula was used initially (88%), than performed secondary (55%). After one year, results were satisfactory in 75.5% of cases.
