THE EFFECTIVENESS of intracordally injected Teflon in restoring or improving the voice in a variety of dysphonias, particularly unilateral recurrent nerve paralysis, has been established by Arnold1-5 and corroborated by others.6,7 Specific indications for the use of Teflon are restricted to situations in which dysfunction is permanent. Where there is doubt as to whether cordal function will return, injection of Teflon must be withheld until at least six months have elapsed. Should this rule not be observed and a paralyzed vocal cord spontaneously recover after the injection of Teflon, the voice would be rendered permanently disturbed instead of returning to its normal preparalytic state by virtue of the foreign material within the substance of the cord acting as a benign space-occupying lesion.
There is a period of time, therefore, during which the patient with dysphonia from unilateral palsy of uncertain prognosis must endure his disability with no immediate
