When evaluation of vocal fold function is indicated in patients undergoing thyroid and parathyroid surgery, TLUSG should not be considered as an alternative to the current practice of flexible fiberoptic laryngoscopy. Adequate ultrasonographic visualization of the vocal folds and arytenoids is challenging, especially in overweight and obese patients and in the postoperative setting.

Recurrent laryngeal nerve (RLN) injury is one of the most common complications of thyroid surgery. Injury to the external branch of the superior laryngeal nerve is less obvious and affects the voice variably; however, it can be of great significance to professional voice users. Recent literature has led to an increase in the use of neuromonitoring as an adjunct to visual nerve identification during thyroid surgery. In our review of the literature, we discuss the application, efficacy and safety of neuromonitoring in thyroid surgery. Although intraoperative neuromonitoring (IONM) contributes to the prevention of laryngeal nerves injury, there was no significant difference in the incidence of RLN injury in thyroid surgery when IONM was used compared with visual identification alone. IONM use is recommended in high risk patients; however, there are no clear identification criteria for what constitutes "high risk". There is no clear evidence that IONM decreases the risk of laryngeal nerve injury in thyroid surgery. However, continuous IONM provides a promising tool that can prevent imminent nerve traction injury by detecting decreased amplitude combined with increased latency.

Background Robotic surgery has been recently used as a novel tool for remote access thyroid surgery. We performed a meta-analysis of the current literature to examine the safety and oncological efficacy of robotic surgery compared to endoscopic and conventional approaches for different thyroid procedures. Methods A systematic search of the online data bases was done using the following (MeSH) terms "robotic surgery," "robotic thyroidectomy," "robot-assisted thyroidectomy," and "robot-assisted thyroid surgery." Outcomes measured included total operative time, length of hospital stay, postoperative thyroglobulin levels, and postoperative complications. Statistical differences were analyzed between groups through the standard means and/or relative risk by using STATA analytical software. Results In this study, 144 articles were identified; of which 18 of them met our inclusion criteria, totaling 4878 patients. Robotic approach was associated with longer total operative time (mean difference of 43.5 minutes) when compared to the conventional cervical approach (95% CI = 20.9-66.2; P < .001). Robotic approach was also found to have a similar risk of total postoperative complications when compared to the conventional and endoscopic approaches. Conclusion Robotic thyroid surgery is as safe, feasible and provides similar periperative complications and oncological outcomes when compared to both, conventional cervical and endoscopic approaches. However, robotic thyroid surgery is associated with longer operative time when compared to the conventional open approach.

In this study, variability in the performance of the GEC was not solely a function of malignancy prevalence and may have been attributable to intrinsic variability of the test sensitivity and specificity. The utility of the GEC in practice is elusive because of this variability. A better definition of the GEC's intrinsic properties is needed.

High-quality, well-designed studies are needed to evaluate the feasibility of incorporating PEI into the treatment protocol of PTC. Although presently inferior to reoperation, PEI has the potential to be a widely accepted and effective nonsurgical treatment option for limited recurrent PTC in poor surgical candidates or patients seeking to avoid multiple reoperations.

Background The use of sealing devices has been established in thyroid surgeries. Recently, LigaSure Small Jaw (LS), a new device that utilizes bipolar energy, was approved by the Food and Drug Administration for use in different head and neck procedures. The purpose of this study is to assess the efficiency and safety of LS use in thyroid surgery compared to Harmonic Focus Scalpel (HS), a well-established device. Methods A prospective study was conducted to compare the efficacy of LS versus the HS. We evaluated 301 patients who underwent surgery at a North American academic institution. Patients were allocated into two groups according to LS or HS use. All patients underwent vocal cord assessment using direct laryngoscopy preoperatively and postoperatively. Analyses were performed to examine the difference in perioperative outcomes resulting from the utilization of either device. Results No difference was seen in operative time between both groups (124.20 ± 68.44 minutes in HS vs 125.20 ± 72.13 minutes in LS, P = .99). Overall complications were similar between both groups (22.86% in HS vs 13.84% in LS, P = .05). However, LS use was also associated with a lower incidence of postoperative transient hypocalcemia as compared to the HS (P = .025). No significant difference was found between both groups regarding the incidence of recurrent laryngeal nerve injury (P = .52). Conclusion The use of the LS is safe, feasible, and is associated with comparable outcomes to HS. Both intraoperative and postoperative variables were similar between both devices. Future larger studies are warranted to further investigate the effect on postoperative transient hypocalcemia.
