OBJECTIVES: @entity13768 ( @entity16549 ) particles are a nonresorbable material that allows for permanent vocal fold augmentation. This study investigated morbidity and @entity1740 in @entity1 treated for unilateral vocal fold paralysis by injection of @entity16549 particles. METHODS: Fourteen @entity1 who had neurogenic unilateral vocal fold paralysis of different causes were included in this prospective study. Each @entity1 underwent videostroboscopic assessment before and after operation. Friedrich's @entity7364 ( @entity7364 ), a score system combining subjective and objective parameters, was used to describe @entity1740 . A @entity7364 of 0 reflects a normal voice, and a @entity7364 of 3 stands for complete aphonia. The @entity16549 particles were injected into the paraglottic space by microlaryngoscopy under general anesthesia. RESULTS: The median follow-up was 4.1 months. There was no complication attributable to the injection of @entity16549 particles. The mean @entity7364 was 2.8 before operation. After the operation, @entity1740 improved significantly in each @entity1 , as reflected by a mean postinjection @entity7364 of 1.4. CONCLUSIONS: Particles of @entity16549 provide a relatively safe and minimally invasive option for permanent vocal fold augmentation. The functional results in terms of voice improvement are comparable to those obtained with other techniques, including thyroplasty. In the European Community, @entity16549 particles are officially approved for use in the @entity1 larynx.
