A thin tracheal silicone washer to solve periprosthetic leakage in laryngectomies: direct results and long-term clinical effects.

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.
