[Closure of esotracheal fistula after phonation implants. Technique and results of tracheal ascension].

Enlarging tracheoesophageal fistula after tracheoesophageal prosthesis for voice rehabilitation remains a major challenge. The authors analyze the results of treatment of 15 severe enlarging tracheoesophageal fistulas among 28 cases (52%) of tracheoesophageal voice rehabilitation which occurred during a 4 years period of time. Among these 15 cases, a spontaneous closure occurred in 3 cases (20%), a two layers closure was performed in 4 cases (26%) and a closure using a tracheal ascension associated with the design of a new tracheostoma was performed on 8 cases (53%). The authors describe the surgical technique and discussed the advantages of surch technique.
