In 1989, I reported a series of 19 cases of unilateral vocal cord para
lysis treated by transcutaneous Teflon injection. At that time it was
shown that unilateral vocal cord paralysis could be effectively treate
d in the office in the unanesthetized patient using a transcutaneous r
oute of injection. Since that time, an additional 43 patients have bee
n treated using a similar technique. The initial impression of safety
and efficacy has been confirmed in this subsequent series. Several ref
inements in this technique have simplified its use and improved its re
liability. No airway complications have been observed to date and no p
atients have required hospital admission. Transcutaneous Teflon inject
ion can be considered a useful method for treatment of vocal cord para
lysis in selected patients.
