Histopathologic study of minced and injected expanded polytetrafluoroethylene (Gore-Tex) in quadriceps muscle of rats for injection laryngoplasty

Pure SH, though easily applicable, was immediately eliminated leaving no trace. In the relatively difficult applications of Gore-Tex mixed with SH, however, there was residual Gore-Tex present in all subjects throughout the study. Gore-Tex may be an applicable material for injection laryngoplasty.
