Introduction and objective: The purposes of this study are to demonstrate the use of the mobile voice lab in type I thyroplasty with Gore-Tex® using analysis of spectrogram and fundamental frequency in the operating room, and also to show how to do this procedure. Methods: Voice samples were recorded in the operating room immediately before and during type I thyroplasty. Six-week postoperative samples were also taken in the voice laboratory. Fundamental frequency and spectral analysis were analyzed. Spectrograms were evaluated by blind panel of 4 judges on a 100. mm visual analogue scale. All three time points were compared and statistical analysis performed. Pre and postoperative V-RQOL scores were also compared. Results: Significant improvement in spectrogram ratings were seen between before and during (P<001), and before and after voice samples (P<017). There was no significant difference between during and after scores, suggesting the persistence of the intraoperative improvement in this measure. Changes in fundamental frequency were not statistically significant, although fundamental frequency tended to increase in women and decrease in men after type I thyroplasty. Mean V-RQOL scores improved from 48.08 a 85.08 (P<001). Conclusions: The mobile voice laboratory may be useful during type I thyroplasty with Gore-Tex®. It offers an opportunity for the surgeon and voice pathologist to continue to collaborate in the treatment of patients with unilateral vocal fold paralysis.
