Abstract
OBJECTIVE Several surgical techniques have been reported for the treatment of unilateral vocal fold paralysis (UVFP). Although the fenestration approach has recently been applied for arytenoid adduction (AA) in some cases, long-term large-cohort studies on its usefulness are lacking. Therefore, this study aimed to evaluate the long-term voice outcomes of this technique in patients with UVFP. STUDY DESIGN Retrospective study. METHODS A total of 168 patients with UVFP underwent laryngoplasty comprising AA performed through fenestration of the thyroid ala combined with a type I thyroplasty (TPI). The maximum phonation time (MPT) and mean airflow rate (MFR) were measured before and after surgery, and voice analysis included an estimation of shimmer and jitter. Anterior and posterior surgical windows were created in the lower thyroid ala and were used for typical TPI and AA, respectively. The window locations were determined based on three-dimensional computed tomography data. AA was performed by pulling the muscular process of the arytenoid cartilage toward the lateral cricoarytenoid muscle through the posterior window without releasing the cricothyroid joint. All surgeries were performed under local anesthesia, and medialization was endoscopically confirmed. RESULTS Postoperative MPT >10 seconds was achieved in 156 of the 168 patients. Postoperatively, MFR improved to <250 mL/s in all but two patients, and MPT, MFR, jitter, and shimmer significantly improved in all patients. Furthermore, perceptual evaluation using the Grade, Roughness, Breathiness, Asthenia, and Strain scale revealed significant improvement in all patients. CONCLUSIONS The fenestration approach preserves the cricothyroid joint and does not open the cricoarytenoid joint; therefore, the laryngeal cartilage is stabilized, and no distortion of the laryngeal framework occurs. Our results showed that combined AA and TPI via the fenestration approach provided stable long-term postoperative voice improvement in patients with UVFP. LEVEL OF EVIDENCE Level 3.

Abstract
PURPOSE Persistent unilateral vocal fold paralysis (UFVP) with glottal insufficiency often requires type I medialization thyroplasty (MT). Previous implants cannot be adjusted postoperatively if necessary. The newly developed APrevent® VOIS implant (VOIS) can provide postoperative re-adjustment to avoid revision MT. The objective of this pilot study is to evaluate the VOIS intraoperatively concerning voice improvement, surgical feasibility and device handling. METHODS During routine MT, VOIS was applied short time in eight patients before the regular implantation of the Titanium Vocal Fold Medialization Implant (TVFMI™). In all patients, perceptual voice sound analysis using R(oughness)-B(reathiness)-H(oarseness)-scale, measurement of M(aximum)-P(honation)-T(ime) and glottal closure in videolaryngoscopy were performed before and after implanting VOIS/TVFMI™. Acoustic analyses of voice recordings were performed using freeware praat. Surgical feasibility, operative handling and device fitting of VOIS and TVFMI™ were assessed by the surgeon using V(isual)-A(nalog)-S(cale). Data were statistically analyzed with paired t test. RESULT All patients showed significant improvement of voice sound parameters after VOIS/TVFMI™ implantation. The mean RBH-scale improved from preoperative R = 2.1, B = 2.3, H = 2.5 to R = 0.6, B = 0.3, H = 0.8 after VOIS and R = 0.5, B = 0.3, H = 0.8 after TVFMI™ implantation. The mean MPT increased from preoperative 7.9 to 14.6 s after VOIS and 13.8 s after TVFMI™ implantation. VOIS/TVFMI™ achieved complete glottal closure in 7/8 patients. The satisfaction with intraoperative device fitting and device handling of VOIS was as good as that of TVFMI™. CONCLUSION The novel APrevent® VOIS implant showed similar intraoperative voice improvement compared to routinely used TVFMI™ without adverse device events and with safe device fitting.

Abstract
OBJECTIVE The purpose of this study was to determine the postoperative pitch range acquired in cases of unilateral vocal fold paralysis, as well as factors affecting outcomes. SUBJECTS AND METHODS We analyzed 39 cases of unilateral vocal fold paralysis for which surgery was performed between January 2006 and January 2009 and for which pitch ranges and the items listed below were measured preoperatively and 1 year postoperatively. Arytenoid adduction (AA) and type I thyroplasty were performed simultaneously in all cases regardless of preoperative severity. AA was performed by the fenestration approach as previously reported. In this procedure, the cricoarytenoid and cricothyroid joints are not released. Correlations between pitch range acquired postoperatively and the following items were examined: (1) pre- and postoperative maximum phonation time (MPT), (2) pre- and postoperative mean airflow rate (MFR), and (3) preoperative pitch range. Furthermore, patients were surveyed regarding their ability to sing after surgery, and the pitch range cutoff value dividing ability and inability to sing was calculated. RESULTS Pitch range increased significantly from 3±4.47 halftones (mean ± standard deviation) preoperatively to 17.5±5.80 halftones postoperatively. Preoperative MPT, MFR, and pitch range did not correlate with postoperative pitch range. Postoperatively, only MPT correlated with the width of postoperative pitch range. Twenty-three of 39 subjects (59%) responded that they were able to sing, and the pitch range cutoff value dividing the two groups was 22 halftones. CONCLUSION AA and type I thyroplasty significantly expanded postoperative pitch range. There was no correlation between preoperative severity and width of pitch range acquired postoperatively.

Abstract
Objective. To objectively assess the voice outcomes of patients with unilateral vocal fold paralysis treated with medialization thyroplasty and arytenoid adduction suture. Study Design. Case series of patients who underwent medialization thyroplasty and arytenoid adduction suture. Preoperative and postoperative voice testing was performed and the data were compared by statistical analysis. Setting. Tertiary referral teaching hospital in Sydney, Australia. Subjects. All patients had a unilateral vocal fold paralysis, with a large posterior glottic gap and vocal symptoms affecting their quality of life. Methods. Thirteen patients with a diagnosis of a unilateral vocal fold paralysis with a large posterior glottic gap, vocal symptoms, and total denervation of the vocal fold underwent medialization thyroplasty and arytenoid adduction suture. The surgery was performed in a novel method under a general anesthetic using a laryngeal mask and with direct intraoperative endoscopic feedback. Preoperative and postoperative measures of voice performance were compared, including acoustic analysis (fundamental frequency, speech intensity against quiet and loud background noise, speech rate) and aerodynamic assessment (airflow, maximum phonation time). Results. Medialization thyroplasty with arytenoid adduction suture significantly improved aerodynamic assessment and phonation duration for both male and female subjects overall. There were 2 of 13 treatment failures. Median follow-up time was 6 months. Conclusion. Preliminary results indicate that in selected patients with vocal fold paralysis, medialization thyroplasty with arytenoid adduction suture leads to significant improvements in objective voice measures. Longer follow-up data are required to further quantify the voice outcomes after this procedure.

Detection of passive movement of the arytenoid cartilage in unilateral vocal-fold paralysis by laryngoscopic observation: useful diagnostic findings. Eur Arch Otorhinolaryngol 2011; 269:565-70.

Abstract
In a previous study of patients with unilateral vocal-fold paralysis (UVFP), three-dimensional computed tomography (3DCT) revealed passive movement during phonation, with the arytenoid cartilage on the paralyzed side pushed to the unaffected side and deviated upwards. The present work compares the 3DCT findings with those obtained by 2-dimensional endoscopy to visualize the vertical passive movement of the arytenoid cartilage. The study population consisted of 23 patients with UVFP and two with laryngeal deviation but normal movement of the vocal folds. Two endoscopic findings represented cranial deviation during phonation: posterior deviation of the arytenoid hump and lateral deviation of the muscular process. These two findings were classified into four grades, ranging from 0 (normal) to 3 (severe). Cranial displacement detected by 3DCT was also classified into four grades. Significant correlations were found between the 3DCT-determined grade of cranial displacement of the arytenoid cartilage and the grade assigned based on the two endoscopic findings. Moreover, lateral deviation of the muscular process was more significantly correlated with 3DCT grade than with endoscopic grade. Thus, endoscopic findings may be useful in the diagnosis of vocal-fold paralysis, and passive lateral deviation of the muscular process as an indicator of UVFP.

Abstract
OBJECTIVE To develop and evaluate the voice outcomes of an approach of arytenoid adduction (AA) through a fenestration of the thyroid ala for unilateral vocal cord paralysis. STUDY DESIGN Twelve consecutive patients with severe unilateral vocal cord paralysis, whose maximum phonation times (MPTs) were less than or equal to 5 seconds, underwent laryngoplasty using an approach of AA performed through a fenestration of the thyroid ala combined with type I thyroplasty. METHOD Two surgical windows were made in the lower part of the thyroid ala. The anterior window was for typical type I thyroplasty, and the posterior window was for AA. AA was performed by pulling the lateral cricoarytenoid muscle (LCA) (5 patients) or muscular process (7 patients) through the posterior fenestration in the contractile direction of the LCA without releasing the cricoarytenoid joint. The operation was performed under local anesthesia with sedation except in two patients who underwent general anesthesia using a laryngeal mask. The vocal cord medialization was confirmed endoscopically during the operation. For all patients, the MPT and mean airflow rate (MFR) were measured before and after the operation. The postoperative voices were analyzed using shimmer and jitter. RESULT All patients achieved a MPT of over 12 seconds. The MFR, which ranged from 340 to 1902 mL/second before the operation, improved to less than 200 mL/second, except in one patient whose MFR was 210 mL/second. Shimmer and jitter improved significantly after the operation. Perceptual evaluation using the GRBAS (grade, roughness, breathiness, aesthenia, strain) scale also improved significantly. CONCLUSION A fenestration-based approach simplified the combination of AA and type I thyroplasty because the two treatments could be performed in the same operating field and provided good voice improvement. Pulling the AA braid in the contractile direction of the LCA and endoscopic vocal cord observation during surgery may have contributed to the positive results.

Abstract
Laryngeal framework surgery is usually performed under local anesthesia. However, some patients are unable to tolerate extended surgery. A case of an 82-year-old woman who underwent medialization thyroplasty and arytenoid adduction of direct lateral cricoarytenoid (LCA) muscle pulling at the same time under general anesthesia using a laryngeal mask is reported. Endoscopic observation through the laryngeal mask allows direct visual control of the vocal cord. The LCA pulling method does not touch the posterior border of the thyroid cartilage so that the laryngeal mask does not disturb the arytenoid adducts.

Abstract
CONCLUSION The three-dimensional prototype model was useful for planning of laryngeal framework surgery. OBJECTIVE To discuss the usefulness of a three-dimensional laryngeal model for laryngeal framework surgery. MATERIALS AND METHODS A three-dimensional laryngeal model was created based on the postoperative helical computed tomography (CT) data of the larynx (case 1) which underwent lateral cricoarytenoid muscle (LCA) pull surgery. LCA pull surgery is a kind of arytenoid adduction for unilateral vocal cord paralysis. A three-dimensional model of case 1 larynx was prototyped using a selective laser sintering method. In case 1, the patient's voice did not improve after LCA pull surgery. The three-dimensional model revealed that the original surgical procedure was not appropriate to obtain optimal arytenoid adduction. According to the analysis of this three-dimensional model, we changed the surgical approach and performed this new refined LCA pull surgery on another patient with unilateral vocal cord paralysis (case 2). RESULTS We were able to pull LCA precisely in case 2. Three-dimensional CT of case 2 after refined LCA pull surgery allowed the correct pulling of LCA and complete adduction of arytenoid. The postoperative voice improved remarkably.
