Management of Unilateral Vocal Cord Paralysis by Injection Medialization with Teflon Paste

Abstract

This paper prospectively analyzes eight patients who were selected for injection medialization of a unilateral vocal cord paralysis by a transcutaneous technique. Preoperative and postoperative videolaryngoscopic recordings of the position of the paralyzed cord were made with a scoring system correlated to the laryngeal airflow measurements. Quantitative acoustic recordings of the patient's voice were also taken and compared with the patient's own subjective analysis of his or her voice. Results indicate that Teflon injection by the transcutaneous method gives a statistically and clinically improved voice in the short term.
