How we do it: use of a venous cannulation needle for endoscopic Teflon injection to the vocal folds

Since its introduction in the 1960's the injection of Teflon into a paralysed vocal fold has become a standard treatment in laryngology. Although in recent years alternative treatments have been suggested, such as the injection of collagen or autogenous fat (Mikaelian et al., 1991), re-innervation procedures and thyroplasty (Crumley, 1990), the use of Teflon is still widespread (Rontal and Rontal, 1991; Dedo, 1992). Various instruments have been developed for the application of Teflon paste and these take the form of a gun-like syringe with a ratchet mechanism. For a number of years we have injected Teflon using a needle marketed for internal jugular vein cannulation along with a plastic 1 ml syringe thus making substantial savings to our department in terms of both time and cost.
