Objective: To compare voice-related outcomes of type 1 thyroplasty using Gore-Tex® between patients with and without augmentation injection laryngoplasty (IL) prior to surgery.
Methods: Forty-five patients who underwent Gore-Tex® thyroplasty at a single institution by a single surgeon between November 2016 and February 2019 were identified as those who previously had IL (n = 20) and those without IL (n = 25). Pre- and post-operative voice-related primary outcomes were evaluated using the GRBAS, and CAPE-V auditory-perceptual rating scales and secondary outcome were evaluated using the VRQOL.
