Abstract

Background and Objectives : Temporary vocal fold injection is not only performed to restore the laryngeal function in temporary unilateral vocal fold paralysis or paresis, but also performed as a test injection prior to the permanent injection. Gelfoam has been safely used for the past several decades for the temporary vocal fold augmentation. Recently, we found a new material, called Radieses Lite, may be used as a temporary injection material. Material and Methods : We report preliminary results of 11 patients who had Radiesse Lite injection with a variety of pathologies. Results : Based on the results from the 6 patients who completed follow-up, the duration of effectiveness of Radiesse Lite seems to be from 2 to 3 months depending on the injection amount. Radiesse Lite satisfies several requirements of the ideal temporary vocal fold injection material in terms of injectability, convenience, duration of effectiveness and safety. Conclusion : The authors concluded that Radiesse Lite might be a good option for temporary vocal fold injection especially in the office setting.
