From the beginning of the teflon injection technique for paralyzed vocal cords there has been an obvious interest in its role as a foreign body. There are a number of previous reports after varying periods of time of residence. This case report describes the tissues response of the foreign body reaction very early, 48 hours after the injection of teflon. It is consistent with early inflammatory foreign body reaction.
This article reviews some of the problems involved in direct laryngoscopy. It suggests adequate preparation and evaluation of the patient to avoid complications. An evaluation of laryngospasm is given. Solutions of the problems are suggested using gear power assistance and adequate drugs for relaxation. The importance of correct positioning of the patient is emphasized and illustrated. This summarizes clinical judgment and successful evaluation of the difficult mechanical problems in the exposure of the vocal cords.
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 situation 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.
