OBJECTIVES: Assessment of the immediate results and long-term clinical effects of a thin silicone washer placed behind the tracheal flange of voice prostheses to treat periprosthetic leakage. PATIENTS AND METHODS: Three year retrospective analysis of 32 laryngectomized patients with 107 periprosthetic leakage events (PLEs). Custom-made silicone washers (outer diameter 18 mm, inner diameter 7.5 mm, thickness 0.5 mm) were placed behind the tracheal flange either in combination with prosthesis replacement or later. RESULTS: There was immediate resolution of periprosthetic leakage in 88 PLEs (median, 38 d; mean, 53 d; range, 8-330 d) and in 6 PLEs with the washer still in situ at the date of analysis (median, 75; mean, 97 d; range, 38-240 d). There was no resolution for periprosthetic leakage in 13 PLEs. Thus, in total, 94 of 107 PLEs (88%) were successfully resolved. In 29 of 32 (91%) patients, the washer resolved the problem at least in one PLE successfully. Twelve of 32 patients, including all 3 with washer failures, also required other interventions to ultimately solve the problem. The vast majority of patients (80%) did not consider placement of the washer to be inconvenient. CONCLUSIONS: In consideration of the high success rate and limited inconvenience for patients, this simple thin silicon washer application provides a good first option for the treatment of periprosthetic leakage.
