[Results of implantation of teflon paste into the vocal cord according to the data of light and electron microscopy].

Light and electron microscopy was used to study 5 observations of the tissue response to the teflon paste implanted into the vocal cords to modulate the vocal function. The study showed that teflon was not an absolutely inert substance, it produced inflammation as giant cell granuloma of foreign bodies. Giant cells of foreign bodies (GCFB) enclosing and resorbing the particles of teflon were found to have all the ultrastructural signs of actively phagocytizing cells presenting with various differentiation. The ultrastructure of GCFB provides support for the fact that the cells making up polykaryons belong to the system of mononuclear phagocytes.
