Introduction: Initial treatment options for unilateral vocal fold paralysis include observation for spontaneous return of function or compensation, voice therapy to stimulate recovery of motion or function, or temporary vocal fold injection medialization to improve glottic closure. Temporary injection medialization can be performed under general anesthesia or in the awake-patient setting with local anesthesia. There are different options of temporary injection materials, being hyaluronic acid (Restylane^®) one of the most popular. Aim: To review our pioneer experience in Chilewith the use of temporary vocal fold injection with hyaluronic acid in the initial management of unilateral vocal fold paralysis. Material and method: Retrospective study involving 15 patients with glottic insufficiency, who underwent percutaneous vocal fold injection medialization with hyaluronic acid. Pre and post procedure quality of voice (VRQOL), tolerance to the procedure, and complications were evaluated. Results: All patients showed significant changes in VRQOL, with a 37% average improvement. The procedure was well tolerated in 93%. No incidents occurred during injection orlater. Conclusions: The temporary vocal fold injection medialization is a well-tolerated, safe and simple procedure that allows significant short-term improvements in vocal quality of patients. Hyaluronic acid is a safe and effective material for temporary vocal foldinjection medialization.
