[Our experiences with the intralaryngeal injection of Teflon (author's transl)].

Since 1973 we have used intralaryngeal injection of Teflon for vocal improvement in cases of unilateral vocal cord paralysis, postoperative scarring of the vocal cord and hypofunctional dysphonia. So far we have treated 84 patients. Teflon is the best substance to use, it remains at the place of instillation, keeps its shape and is not resorbed. As immediate reactions we have observed sporadic oedematous swellings of the injected vocal cord. No long-term reactions are know. The functional results are vocal improvement without restriction of the respiratory passage.
