Teflon injection: pointers and pitfalls.

Abstract

Our objective is to clarify the procedure used in a series of 335 cases of injection of paralyzed vocal cords. Over 29 years, questions have arisen about the procedure, mostly from trainees. They relate to timing, indications, method, and follow-up. Results of the procedure, when properly performed, have been highly successful. Where indications are appropriate, injection is usually uncomplicated, relatively safe, and done with minimum instrumentation. This is our response, in a question-and-answer format, to the most frequent queries.
