“…However, variations in thyroid cartilage dimensions between different ethnic groups, sexes, and individuals 19,20 make it difficult to standardize procedures, especially if the implant shape, 21 dimensions, and site cannot be determined prior to the surgery, leading to discrepancies in results. 22 Imaging studies, such as preoperative CT-scans 23 or digital volume tomography, 24 have been proposed for planning MT procedures to individually customize implants.…”

Objectives/Hypothesis: Evaluation of the clinical outcomes after 6 months of treatment with a novel adjustable implant, the APrevent ® Vocal-Implant-System (VOIS), in conjunction with medialization thyroplasty (MT) in patients with unilateral vocal fold paralysis.Study Design: Prospective case series study at single tertiary referral center.Methods: Preoperative and 1 week, 7 weeks, and 6 months postoperative glottal efficiency (maximum phonation time [MPT]), voice quality (including GRBAS-scores and acoustic parameters) and self-perceived voice-related handicap (voice handicap index [VHI-30]) were measured and analyzed, whereas type of vocal fold closure was evaluated and determined by flexible videolaryngoscopy based on Södersten and Lindestad classification (Wilcoxon signed-rank test).Results: Thirteen patients underwent MT with VOIS under local anesthesia. Six months after surgery, the VHI-30 and MPT had improved from a preoperative mean of 75.0 AE 22.9 and 2.7 AE 2.1 s to a postoperative mean of 20.6 AE 19.7 and 6.3 AE 4.0 s, respectively. The mean GRBAS score improved from preoperative scores of G preop = 2.7, R preop = 2.6, B preop = 2.6, A preop = 2.2, and S preop = 2.0 to G postop = 0.3, R postop = 0.3, B postop = 0.2, A postop = 0.2, and S postop = 0.3 at 6 months postoperatively. Improved glottal closure was achieved in all patients (n = 13). Five patients received postoperative adjustment for the optimization of voice quality and glottal closure. No intra-or postoperative complications were observed. Significant improvements in acoustic parameters, including percentage jitter, percentage shimmer, and signal-to-noise ratio, were also observed after MT. All results were statistically significant (P < .05, Cohen's d > .8).Conclusions: APrevent ® VOIS-Implantation is a safe procedure with good voice outcomes. Postoperative adjustments can be performed smoothly to optimize voice quality and glottal closure.

“…Similar to our techniques, Frizzarini et al demonstrated that implants that were prefabricated based on measurements obtained from the scans, accurately medialising the entire free border of the vocal fold. In addition, our method allows for fabrication of implants to medialise select parts of a vocal fold.…”
