Abstract

We examined vocal outcomes of patients who underwent type I thyroplasty for unilateral vocal fold paralysis. Specifically, the vocal outcomes were compared between 15 patients whose thyroplasties were performed with silicone and 15 patients whose thyroplasties were performed with Gore-Tex.The examined clinical characteristics did not differ significantly between the groups. The vocal outcomes were evaluated by aerodynamic and acoustic measurements.Aerodynamic examination indicated significant postoperative improvements in the maximum phonation time and mean flow rate in both groups. Shimmer was significantly improved only in the Gore-Tex group. A direct comparison between groups showed no significant difference in the degree of improvement of the vocal parameters, except for a significant improvement in the noise-to-harmonics ratio in the Gore-Tex group. The duration of surgery was significantly less in the Gore-Tex group than in the silicone group.Gore-Tex thyroplasty is considered to be comparable to silicone thyroplasty in terms of postoperative vocal outcomes. Gore-Tex thyroplasty enables a less invasive procedure with a shorter surgical duration and easier adjustment of medialization due to its flexibility.
