[Teflon paste injection in vocal cord paralysis. Our experience and the future of injection techniques (author's transl)].

Fifty nine cases of vocal cords in abduction following recurrent nerve paralysis has been treated with teflon paste injection. Most of them were secondary to pulmonary neoplasms. All injections are done under general anesthesia and direct laryngoscopy. Our technique give good results in 78/100 of the case with minimal complication (5/100). In the future, more physiological implants are to be used even if reinervation of tyroarytenoid muscle with neuro-muscular flaps could be used sometimes.
