Polydimethylsiloxane in the Human Vocal Fold: Description of Partial Explantation

Abstract

We describe here for the first time a partial explantation of polydimethylsiloxane in a patient 7 years after implantation caused by faulty positioning of the implant. The histopathologic examination demonstrated that the material that displayed green autofluorescence in hematoxylin-eosin staining was biologically inert and stable. Major inflammatory reaction could not be ascertained.

“…The material used (VoxTM, Uroplasty Inc, Minnetonka, Minnesota, USA) has not been associated with migration and granuloma formation, known complications of other nonabsorbable bulking agents. 11 As the case reports indicate, the optimal management strategy for this newly described condition is yet to be determined.…”
