“…Interestingly, the assessment of the Grade of dysphonia at 3 months showed a further decrease of the intraoperative values supporting the earlier observation that the intraoperative environment is not the ideal assessment situation and that further improvements are likely after proper wound healing and speech-language therapy. The overall decrease of the Grade score from 1.4 before surgery to 0.4 at 3 month post-surgery (Δ 1.00 points; p = 0.071), although not significant, is in line with earlier studies that have shown improvements in overall Grade score after MT + AA ranging from 1.0 to 2.5 points [ 8 , 22 – 24 ]. Finally, the VHI total scores decreased significantly after surgery from a preoperative mean of 71 to 13 at 3 months (Δ 58; p = 0.008) which can be considered as normal [ 22 ].…”

“…Finally, the VHI total scores decreased significantly after surgery from a preoperative mean of 71 to 13 at 3 months (Δ 58; p = 0.008) which can be considered as normal [ 22 ]. Various studies have used the VHI-30 score for voice outcome analysis in MT + AA cohorts reporting mean improvements ranging from 50.3 to 78.8 points [ 5 , 23 , 24 ].We, therefore, conclude that our data show a relevant voice improvement after MT + AA that is comparable with literature. However, in our case intra-operative measurements were not finite and continued to improve post-operatively in most cases.…”

Purpose Arytenoid adduction as an addition to medialisation thyroplasty is highly advocated by some surgeons in selected cases but deemed less necessary by others in patients with unilateral vocal fold paralysis. This study aims to evaluate the additional benefits on voice outcome of arytenoid adduction in patients with unilateral vocal fold paralysis undergoing medialisation thyroplasty using intra-operative voice measurements. Design/methods A prospective study was conducted. Voice audio recordings were obtained at 4 moments; 1. direct prior to the start of surgery, 2. during surgery after medialisation thyroplasty, 3. during surgery after medialisation and arytenoid adduction, 3 months postoperative. At these same timepoints patients rated their own voice on a numeric rating scale between 0 and 10. The blinded recordings were rated by consensus in a team of experienced listeners, using the Grade of the GRBAS scale. Furthermore, the Voice Handicap Index was administered before and at 3 months after surgery. Results Ten patients who underwent medialisation and arytenoid adduction at our tertiary referral hospital between 2021 and 2022, were included. One patient was excluded after surgery. The intraoperative measurements showed a Grade score of 1.4 preoperatively, improving to 1.2 after medialisation, 1.2 after medialisation and arytenoid adduction, and further improving to 0.4 at 3 months postoperative, which was a not statistically significant improvement (p = 0.2). The intraoperative subjective numeric rating scale showed a statistically significant improvement from 3.9 preoperatively, to 6.1 after medialisation, 7.1 after medialisation and arytenoid adduction and a 7.6 at 3 months postoperative (p = 0.001). The Voice Handicap Index total score showed a statistically significant improvement from 71 points before surgery to 13 at 3 months after surgery (p = 0.008). Conclusions Our study using intraoperative voice measurements indicate that the addition of arytenoid adduction to medialisation thyroplasty is a benefit in selected patients although more studies are needed due to the many limitations inherent to this field of investigation.

Objective: To summarize and compare current common treatments in recurrent laryngeal nerve injury (RLNI). In addition, we introduced nerve tissue engineering technology in RLNI animal models. This review is a comprehensive summary of current therapies for unilateral RLNI.Background: RLNI is a common complication in thyroid surgery. Although preoperative imaging and intraoperative nerve monitoring are widely applied, some damage to nerves is still inevitable. Currently, advances in nerve repair and regeneration have been made, but relatively few studies have focused on RLNI.In this review, we summarized and compared current common treatments in RLNI. Methods:We searched the literature on PubMed and Web of Science, and chose studies about RLNI in thyroid surgery. Keywords included the following terms: "recurrent laryngeal nerve regeneration", "injection laryngoplasty", "type I thyroplasty", "arytenoid adduction", and "nerve tissue engineering technology". Only English language studies were included. In the section on nerve tissue engineering technology, we described the application in detail in the table below.Conclusions: Currently, the majority of treatments could obtain different effects to some extent, but there are still shortcomings that need to be overcome further overcome. Therefore, potential exploration such as nerve tissue engineering technology is worthy of attention.

“…Besides, for voice rehabilitation other surgical techniques including laryngoplasties and thyreoplasties [12][13][14] have been established. For laryngoplasties which augment the vocal folds, many different synthetic or autologous fillers such as polytetrafluoroethylene (Teflon), calcium hydroxylapatite (CaHa), collagen, hyaluronic acid and fat have been used [15][16][17].…”

Objectives The purpose of this study was to analyze the short- and middle-term effects of primary injection laryngoplasty in patients having tumor resection within the same surgery concerning the vocal outcome. Injection laryngoplasty was performed after harvesting autologous adipose tissue via lipoaspiration. Methods A prospective study was performed with 16 patients (2 female; 14 male) who received tumor resection and an injection laryngoplasty using autologous adipose tissue during a single stage procedure. Multidimensional voice evaluation including videostroboscopy, patient self-assessment, voice perception, aerodynamics, and acoustic parameters was performed preoperatively, as well as 1.5, 3 and 6 months postoperatively. Results Results show an improvement in the roughness–breathiness–hoarseness (RBH) scale, voice dynamics and subjective voice perception 6 months postoperatively. Maintenance of Voice Handycap Index, jitter and shimmer could be observed 6 months postoperatively. There was no deterioration in RBH and subjective voice perception 2 and 6 weeks postoperatively. No complications occurred in the fat harvesting site. Conclusions Using the lipoaspiration and centrifugation approach, primary fat injection laryngoplasty shows short-term maintenance und middle-term improvement in voice quality in patients with vocal fold defect immediately after chordectomy 6 months postoperatively. Cancer recurrence rate is comparable to the reported cancer recurrence rate for laryngeal carcinoma and thus not elevated through primary augmentation.
