Polydimethylsiloxane in the human vocal fold: description of partial explantation.
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.
