Experience with Vocal Cord Injection

TLDR

For 14 years, FDA‑accredited investigators have injected a Teflon®‑glycerin mixture into lateral‑lying, paralyzed vocal cords. The study introduces a new surgical technique that injects sterile glycerin into comparable vocal cords in acute cases. The technique is performed via direct or indirect laryngoscopy, allowing immediate cough improvement and reducing the need for tracheotomy. In the largest reported series, the method restored voice, laughter, strain ability, prevented aspiration, and eliminated some tracheotomies.

Abstract

For 14 years investigators accredited by the FDA have been injecting a Teflon® - glycerin mixture into lateral-lying, paralyzed vocal cords. This paper represents a summary of the work of this author, including successes, failures, and complications; it is the largest reported series, plus that of accredited investigators. The method described is exceptionally useful; it has restored voices, laughter, the ability to strain, and has prevented aspiration. A new surgical technique involving the injection of sterile glycerin into comparable vocal cords in acute new situations is also described. This is done by direct or indirect laryngoscopy, and has been used to eliminate some tracheotomy surgery by virtue of the immediately improved cough effectiveness.
