Chirurgische Therapie von Stimmshunt-Komplikationen unter besonderer Berücksichtigung eines supraösophagealen Refluxes

Abstract

Approximately a quarter of all patients who undergo prosthetic voice restoration develop periprosthetic leakage with aspiration symptoms within 1 to 4 years following surgery. Depending on the severity of fistula enlargement, treatment ranges from conservative approaches to surgical procedures. In some cases, however, these measures prove unsuccessful. The causes of treatment failure and fistula enlargement are not fully understood. There is growing evidence, however, that the presence of coexisting supraesophageal reflux can contribute to fistula complications. We report the case of two patients with voice prostheses and simultaneous severe reflux disease who underwent multiple failed attempts at fistula closure. After effective reflux therapy, the fistulas could eventually be closed successfully.
