[Implantation microsurgery in the phoniatric practice].

The paper reports the results of teflon paste implantation into the vocal folds of 368 patients with laryngeal unilateral paralysis and scar deformities, atrophy of vocal muscles. Implantation of teflon paste polytef produces a high functional effect in unilateral laryngeal paralysis. 38 patients underwent implantation with collagen. The response of the adjacent tissues to collagen injection is minimal positively comparing to teflon. However, 10 patients needed more injections of liquid collagen 6-18 months following the initial administration because of collagen metabolism.
