The Evaluation of the Short-Term Voice Outcome of Injection Laryngoplasty Using Two Types of Calcium Hydroxylapatite (Radiesse versus Facetem) / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES@#Radiesse® is a widely used calcium hydroxyapatite (CaHA) injection material used for vocal fold injection. Recently, a new CaHA injection material (Facetem ®) which complements the structural disadvantages of Radiesse has been developed and released in the market. The aim of this study is to compare the efficacy and short-term voice outcome of these two CaHA materials.SUBJECTS AND METHOD: A retrospective analysis was performed for 70 patients with unilateral vocal fold paralysis who underwent vocal fold injection using CaHA materials. Acoustic voice analysis, maximal phonation time (MPT), voice handicap index (VHI), and Grade, Roughness, Breathiness, Asthenia, Strain (GRBAS) scale were evaluated between Radiesse and Facetem injection group.@*RESULTS@#Both groups showed a signifcant improvement of MPT, VHI, and G, B, A scale after injection. The Facetem group showed similar voice improvement as the Radiesse group, where pre- and postoperatively objective and subjective voice evaluation results were compared.@*CONCLUSION@#Our study reveals that there is no significant difference in efficacy and nor any short-term vocal improvement between Radiesse and Facetem. Therefore, the use of Facetem as CaHA injection material could be considered as an alternative material for patients with unilateral vocal cord paralysis.
