Abstract
Radiofrequency ablation (RFA) offers a minimally invasive solution for benign, autonomously functioning (AFTN), and malignant thyroid nodules. The technique utilizes high-frequency alternating current to induce coagulative necrosis, effectively destroying target tissue. RFA is performed in the outpatient setting with local anesthesia and sonographic guidance. RFA is effective in producing substantial volume reduction rates in benign nodules and is emerging as a favorable option in AFTN and papillary thyroid microcarcinoma. RFA's advantages include lower complication rates, minimal scarring, and improved quality-of-life outcomes compared to surgery. However, its efficacy in larger and recurrent malignancies requires further investigation.

Abstract
Thyroidectomy is a commonly performed surgery for thyroid cancer, Graves' disease, and thyroid nodules. With the increasing incidence of thyroid cancer, understanding the anatomy and surgical techniques is crucial to ensure successful outcomes and minimize complications. This review discusses the anatomical considerations of the thyroid and neck, including lymphatic drainage and the structures at risk during thyroidectomy. Emphasis is placed on the significance of cautious dissection to preserve critical structures, such as the parathyroid glands and recurrent laryngeal nerve. Neck dissection is also explored, particularly in cases of lymph node metastasis, in which its proper execution is essential for better survival rates. Additionally, this review evaluates various thyroidectomy techniques, including minimally invasive approaches, highlighting their potential benefits and limitations. Continuous surgical knowledge and expertise updates are necessary to ensure the best results for patients undergoing thyroidectomy.

Wu J, Zhang Y, Shen L. Effect of modified endotracheal intubation protocol combined with early oral intake on postoperative recovery quality in thyroid and parathyroid surgery at a tertiary hospital in China: a 2x2 factorial randomised controlled trial protocol. BMJ Open 2024; 14:e075999. [PMID: 38238052 PMCID: PMC10806907 DOI: 10.1136/bmjopen-2023-075999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Accepted: 12/22/2023] [Indexed: 01/23/2024] Open
Abstract
INTRODUCTION Early oral intake (EOI) is supposed to be safe and beneficial to patients' recovery. However, the optimal timing of resuming oral intake has not been validated in thyroid and parathyroid surgery. On the other hand, a modified electromyography (EMG) endotracheal intubation protocol with real-time EMG monitoring during video laryngoscope/fibrescope-guided intubation was presented in 2022, which was regarded as an effective way to shorten the intubation time. We aimed to use Quality of Recovery-15 (QoR-15) questionnaire to compare the efficacy and safety of different EMG endotracheal intubation protocols combined with different postoperative oral intake strategy in thyroid and parathyroid surgery. METHODS AND ANALYSIS This prospective, single-centre, 2×2 factorial, randomised controlled trial will be conducted in the Peking Union Medical College Hospital (PUMCH), China. We plan to recruit 200 adult patients who will receive thyroid or parathyroid surgery under intraoperative nerve monitoring. Eligible patients will be randomly divided into two groups, which will receive either the modified intubation protocol (M group) or conventional intubation process (C group). After patients enter postanaesthesia care unit and Steward scores ≥4, they will be randomly divided into two groups again, which will receive early resumption of oral intake (E group) or delayed resumption of oral intake (D group). Patients will be followed up during hospitalisation and the QoR-15 questionnaire will be administered to compare the quality of recovery on the day before surgery (T0), the first day after surgery (T1) and the day of discharge (T2). The primary outcome is the QoR-15 scores at T1. ETHICS AND DISSEMINATION The study protocol has been approved by the Research Ethics Committee of Peking Union Medical College Hospital (IRB K-2501). All participants will give written informed consent before participation. The results from this study will be shared at conferences and disseminated in international journals. TRIAL REGISTRATION NUMBER NCT05624463.

Advantages of Intraoperative Neuromonitoring Over Direct Visualization of the Recurrent Laryngeal Nerve During Thyroidectomy. Cureus 2023; 15:e43869. [PMID: 37736436 PMCID: PMC10511205 DOI: 10.7759/cureus.43869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/21/2023] [Indexed: 09/23/2023] Open
Abstract
BACKGROUND The well-recognized risk of injury to the recurrent laryngeal nerve (RLN) during thyroidectomy has instigated various preventive measures. One such measure involves directly visualizing the RLN, but this is not always feasible in practice. A more recent approach involves using intraoperative neuromonitoring to identify and preserve the RLN. This study aims to evaluate the effectiveness of intraoperative neuromonitoring compared to single visualization of the RLN in averting nerve injury. METHODS We conducted a retrospective, observational, and descriptive study on a cohort of 218 patients. A Chi-square test was employed to determine the influence of intraoperative neuromonitoring on the incidence of nerve injury, with P < 0.05 considered statistically significant. We used Jamovi software version 2.3.18 to analyze the data. RESULTS Of the 218 patients, intraoperative neuromonitoring was used in 150 (68.8%) cases; none of which resulted in nerve injury. Conversely, 68 (31.2%) patients underwent surgery without the use of neuromonitoring, with two (2.9%) patients in this group experiencing nerve injury (p=0.037). In comparison, the risk of nerve injury was 0% in the group monitored intraoperatively and 2.94% in the group that did not undergo intraoperatively neuromonitoring. Further, the relative risk of complications was 0.66% in patients operated with neuromonitoring, while it was 5.88% in the group operated without neuromonitoring, thus demonstrating a clinically significant protective against vasculonervous complications. CONCLUSION The results advocate for the use of intraoperative neuromonitoring, whenever available, as it is a safe method for significantly decreasing the incidence of RLN injury during thyroidectomy compared with only visualization.

Abstract
Intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) has been shown in adults to minimize nerve palsy after thyroid surgery, but only few studies on its efficacy in a pediatric population have been reported. We conducted a retrospective study on patients operated for thyroid lesions from 2016 to 2022. The analyzed population was divided in two groups: patients treated from 2016 to 2020, when the identification of the RLN was performed without IONM (Group A); and patients treated since 2021, when IONM was implemented in every surgical procedure on the thyroid (Group B). Intraoperative Neurophysiological Monitoring was performed by using corticobulbar motor-evoked potentials and continuous electromyography. Twentyfive children underwent thyroid resection, 19 (76%) of which due to thyroid carcinoma. Each patient's recurrent nerve was identified; IONM was used in 13 patients. In Group A, one temporary nerve palsy was identified postoperatively (8.3%), while in group B one nerve dysfunction occurred (7.7%). No statistically significant difference was found between the two groups in terms of post-operative RLN palsy. No surgical complication due to the use of IONM was reported. In children and teenagers, intraoperative neuromonitoring of the recurrent laryngeal nerve is a safe and accurate method, minimizing the risk of nerve damage.

Abstract
The most fearsome complication in thyroid surgery is the temporary or definitive recurrent laryngeal nerve (RLN) injury. The aim of our study was to evaluate the impact of intraoperative neuromonitoring (IONM) on postoperative outcomes after thyroid and parathyroid surgery. From October 2014 to February 2016, a total of 80 consecutive patients, with high risk of RLN injuries, underwent thyroid and parathyroid surgery. They were divided in two groups (IONM group and control group), depending on whether neuromonitoring was used or not. We used the Nerve Integrity Monitoring System (NIM)-Response 3.0® (Medtronic Xomed®). The operation time (p = 0.014). and the length of hospital stay (LOS) (p = 0.14) were shorter in the IONM group. Overall mean follow-up was 96.7 ± 14.3 months. The rate of transient RLN palsy was 2.6% in IONM group and 2.5% in the control group (p = not significant). Only one case of definitive RLN injury was reported in control group. No differences were reported between the two groups in terms of temporary or definitive RLN injury. Routine use of IOMN increases the surgery cost, but overall, it leads to long-term cost savings thanks to the reduction of both operating times (106.3 ± 38.7 vs 128.1 ± 39.3, p: 0.01) and LOS (3.2 ± 1.5 vs 3.7 ± 1.5 days, p = 0.14). Anatomical visualization of RLN remains the gold standard in thyroid and parathyroid surgery. Nevertheless, IONM is proved to be a valid help without the ambition to replace surgeon's experience.

Abstract
The field of endocrine surgery has expanded from the traditional open neck approach to include remote access techniques as well as minimally invasive approaches for benign and malignant thyroid nodules. In experienced hands and with careful patient selection, each approach is considered safe, however complications can and do exist. Post-operative dysphonia can have serious consequences to the patient by affecting quality of life and ability to function at work and in daily life. Given the significance of post-procedural dysphonia, we review the surgical and non-surgical techniques for minimizing and treating recurrent laryngeal nerve injury that can be utilized with the traditional open neck approach, remote access thyroidectomy, or minimally invasive thermal ablation.

Time to Revisit a Low-Cost Alternative? Palpation Assessment Nerve Monitoring (PANM) for Recurrent Laryngeal Nerve to Predict Postoperative Vocal Cord Function-a Validation Study Using an In-House Neuromonitoring Device. Indian J Surg Oncol 2022; 13:33-39. [PMID: 35462675 PMCID: PMC8986893 DOI: 10.1007/s13193-020-01272-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 12/07/2020] [Indexed: 10/22/2022] Open
Abstract
Neuromonitoring has proved to be a useful technique in reducing nerve injury during thyroid surgery; however, costs continue to limit its use in resource-constrained settings. This study was done to assess the functional integrity of the recurrent laryngeal nerve (RLN) during thyroid surgery using palpation assessment of posterior cricoarytenoid muscle twitch in response to RLN stimulation. Between August 2016 and July 2017, 24 patients with 47 nerves at risk (NARs) underwent thyroid surgery with visual identification and testing of 44 RLNs. The functional integrity of the RLN was checked by stimulation of the RLN. Intraoperative assessment showed 100% sensitivity and positive predictive value in predicting postoperative vocal cord function. The postoperative vocal cord assessment confirmed all 44 nerves tested to be normally functioning. The mean (standard deviation) peak-to-peak amplitude and latency of the CMAP were 0.889 (0.740)/1.336 (1.660) mV and 2.295 (0.319)/2.217 (0.393) ms for left/right side NARs, respectively, with no statistically significant difference (P > 0.05). Palpation assessment of the posterior cricoarytenoid muscle provides a simple and reliable technique for confirming integrity of the RLN. Combining palpation assessment with CMAP from the inferior constrictor muscle may help reduce potential false negative results. With the use of our in-house built device which is significantly cheaper than the commercial ones, this could be considered a low-cost alternative to current established techniques.

Abstract
Continuous and intermittent intraoperative nerve monitoring (IONM) has become an important asset for endocrine surgeons over the past few decades. The ability to determine neurophysiologic integrity of the recurrent laryngeal nerve (RLN) and external branch of the superior laryngeal nerve (EBSLN) on top of identification and meticulous dissection of the nerve in the surgical field, has allowed for advances in technology and improved outcomes when it comes to prevention of vocal fold immobility. This article aims to compare in review continuous and intermittent nerve monitoring (CIONM, IIONM), as well as review the current paradigms of their use. This article will also discuss the future of intraoperative nerve monitoring technologies in scarless thyroid surgery and percutaneous approaches to thyroid pathology in form of radiofrequency ablation (RFA).

Abstract
BACKGROUND We present our experience with the first five thyroidectomies and parathyroidectomy in Kuwait performed via the transoral endoscopic vestibular approach. METHODS Retrospective data collection for all trans-oral endoscopic vestibular approach endocrine surgeries performed at a single institution in Kuwait between November 2019 and February 2021. Information on patient demographics, perioperative management and complications were collected and reviewed. OUTCOMES All 5 cases were completed successfully; the intended specimen was extracted successfully via the trans-oral endoscopic vestibular approach and conversion to traditional trans-cervical approach (TCA) was not required. Operative time for the parathyroidectomy case was 225 min and the average operative time for the remaining 4 cases, thyroidectomies, was 151 min. Blood loss was minimal, and length of hospital stay was between 24 and 48 h. One patient had a transient mental nerve injury, and one patient experienced a postoperative seroma which required aspiration. One case required completion thyroidectomy as histopathology revealed papillary thyroid carcinoma. CONCLUSION Transoral vestibular approach is a scar free and safe approach to thyroidectomies and parathyroidectomies. Careful patient selection and counselling with regards to risk versus benefit is required. It is an excellent alternative to the traditional transcervical approach and offers great cosmetic results.

Abstract
BACKGROUND Recurrent laryngeal nerve (RLN) injury is a significant complication after thyroidectomy. Understanding risk factors for RLN injury and the associated postoperative complications may help inform quality improvement initiatives. METHODS The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) thyroidectomy-targeted database was utilized for patients undergoing total thyroidectomy between 2016 and 2017. Univariable and multivariable regression were used to identify factors associated with RLN injury. RESULTS A total of 6538 patients were identified. The overall rate of RLN injury was 7.1% (467/6538). Of these, 4129 (63.1%) patients had intraoperative neuromonitoring (IONM), with an associated RLN injury rate of 6.5% (versus 8.2% without). African American and Asian race, non-elective surgery, parathyroid auto-transplantation, and lack of RLN monitoring were all significantly associated with nerve injury on multivariable analysis (P<.05). Patients with RLN injury were more likely to experience cardiopulmonary complications, re-intubation, longer length of stay, readmission, and reoperation. Patients who had IONM and sustained RLN injury remained at risk for developing significant postoperative complications, although the extent of cardiopulmonary complications was less severe in this cohort. DISCUSSION Recurrent laryngeal nerve injury is common after thyroidectomy and is associated with significant morbidity, despite best practices. Attention to preoperative characteristics may help clinicians to further risk stratify patients prior to thyroidectomy. While IONM does not mitigate all complications, use of this technology may decrease severity of postoperative complications.

Abstract
Background Thyroid surgery, performed for benign or malignant pathologies, is one of the most frequently performed procedures and its frequency has even been increasing in recent years. Postoperative bleeding, recurrent laryngeal nerve (RLN) palsy, associated to dysphonia, dysphagia, dyspnea, and hypoparathyroidism represent the most fearful and common complications. We conducted a multicenter, observational study of retrospectively collected data in three high-volume referral centers, enrolling all patients undergone to thyroid surgery between January 2016 and December 2017 in Parma University Hospital, Cagliari University Hospital and Ferrara University Hospital. Materials Patients were divided into five groups, differentiated thyroid carcinoma, medullary thyroid carcinoma, non-toxic benign pathology, hyperfunctioning benign pathology and NIFTP (Non-invasive Follicular Thyroid neoplasm with Papillary-like nuclear features). A follow up at 7 and 30 days was executed, evaluating the onset of paresthesia, dysphonia and dysphagia. A 6-month follow-up was conducted in cases of early complications. Results Totally, 1252 patients were eligible for the study: 907 female and 345 male, with a female to male ratio of 2.6:1 and an average age of 53.428. Total thyroidectomy was performed in 1022 cases, lobectomy in 230. After 6 months we recorded paresthesia in 0.5%, dysphonia in 1.8% and dysphagia in 0.5%. Conclusion Our study confirms once again that a share of morbidity escapes the possibilities of prediction and control by the operator, depending on patient anamnestic, pathological or anatomical factors.

Abstract
Objective This study evaluated the diagnostic accuracies of various forms of intraoperative neural monitoring (IONM) in terms of predicting vocal cord palsy after thyroidectomy. Methods Two authors independently reviewed the six databases (PubMed, the Cochrane database, Embase, the Web of Science, SCOPUS, and Google Scholar) from their dates of inception to March 2021. Intraoperative electromyographic neuromonitoring (IONM) was compared with laryngoscopic detection (the reference method). True-positive, true-negative, false-positive, and false-negative data were extracted from each study. Methodological quality was evaluated using the Quality Assessment of Diagnostic Accuracy Studies ver. 2 tool. Results Twenty-seven prospective or retrospective studies were included. The diagnostic odds ratio for IONM was 152.9623 ([95% confidence interval [75.4249; 310.2085]. The area under the summary receiver operating characteristic curve was 0.966. The sensitivity, specificity, negative predictive value, and positive predictive value were 0.8219 ([0.6862; 0.9069]), 0.9783 ([0.9659; 0.9863]), 0.9943 ([0.9880; 0.9973]), and 0.5523 ([0.4458; 0.6542]), respectively. The correlation between sensitivity and false-positive rate was 0.200, indicating the absence of heterogeneity. Subgroup analysis showed that the diagnostic accuracies of the continuous IONM was higher than those of intermittent IONM, and recent publications (> 2011) was higher than early publication (< 2010). Conclusions As the technology and knowledge of IONM have been accumulated and progressed over the past decades, the predictive value of IONM in postoperative vocal cord palsy has also improved. Moreover, the advances of continuous IONM technology could make a breakthrough in vocal cord evaluation after thyroid surgery.

Abstract
Abstract
Purpose of Review
Purpose of the present review is to illustrate the current state of the art concerning continuous intraoperative recurrent laryngeal nerve monitoring (cIONM) for thyroid surgery.
Recent Findings
cIONM potentially leads to an improved postoperative vocal cord palsy rate, compared to the intermittent technique. There are currently two main approaches for cIONM: either conventional cIONM based on vagal nerve stimulation or experimental methods, which do not require the positioning of a vagal nerve electrode. One of these methods is the recently described technique “LAR-cIONM,” which utilizes the laryngeal adductor reflex.
Summary
cIONM represents an advancement of intermittent nerve monitoring, which allows for an immediate reaction to signal changes. Threshold values and guidelines to prevent recurrent laryngeal nerve palsy were validated for the direct stimulation of the vagal nerve and require verification for alterative cIONM methods, including LAR-cIONM.

Abstract
OBJECTIVES To determine the prevalence of separate and combined voice and swallowing impairments before and after total thyroidectomy and to delineate risk factors for these symptoms. METHODS Retrospective review of 592 consecutive patients who underwent total thyroidectomy from July 2003 to August 2015. RESULTS Combined voice and swallowing problems occurred preoperatively in 4.7% (11/234), 3.3% (3/92), and 6.0% (16/266) of patients with malignancy, hyperthyroidism, and benign euthyroid disease, respectively. Postoperatively, prevalence was 5.1%, 2.2%, and 1.9%, respectively. Benign euthyroid disease (20.7%) had the greatest risk of preoperative dysphagia (P = 0.003) and the largest glands (P < 0.001). Comparing before and after surgery, the cancer and benign euthyroid groups had decreased dysphagia (cancer: 11.5% vs. 6.0%, P = 0.034; benign: 20.7% vs. 3.8%, P < 0.001) but increased dysphonia (cancer: 19.2% vs. 28.6%, P = 0.017; benign: 15.8% vs. 27.1%, P = 0.002). Overall, 23/592 (3.9%) developed new dysphagia and 122/592 (20.6%) developed new dysphonia after surgery. Intraoperative recurrent laryngeal nerve transection occurred in 12 cases (2.0%). CONCLUSIONS Total thyroidectomy resolved dysphagia but increased dysphonia in benign and malignant euthyroid patients. Voice and swallowing problems following thyroidectomy occurred more frequently than intraoperative recurrent laryngeal nerve transection, confirming symptoms often occur in the absence of suspected nerve injury.

Abstract
Objective To investigate whether intraoperative neuromonitoring (IONM) has a
significant advantage in reducing the incidence of recurrent laryngeal nerve
(RLN) injury. Methods Patients who underwent thyroid and parathyroid surgery from October 2012 to
December 2017 at the Center for Thyroid and Breast Surgery of Xuanwu
Hospital were retrospectively analyzed. They were divided into the IONM
group and visualization alone group (VA group) according to whether IONM was
used. Results In total, 1696 nerves at risk of injury (IONM group, n = 1104; VA group,
n = 592) were included in the analysis. Among the high-risk nerves,
permanent damage occurred in no cases in the IONM group but in one case in
the VA group. Because the higher proportion of central lymph node metastasis
caused difficulties in central cervical lymph node dissection and
identification of the RLN, the patients undergoing lateral cervical lymph
node dissection in the VA group had a significantly higher risk of
postoperative RLN injury (11.76% vs. 0.00%). Conclusion IONM technology has advantages in protection of the RLN, especially in
high-risk nerves and patients with a high proportion of central lymph node
metastasis who require central and lateral cervical lymph node
dissection.

Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA): Surgical Outcomes and Learning Curve. J Clin Med 2021; 10:jcm10040863. [PMID: 33669741 PMCID: PMC7922263 DOI: 10.3390/jcm10040863] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 02/14/2021] [Accepted: 02/15/2021] [Indexed: 12/15/2022] Open
Abstract
The transoral endoscopic thyroidectomy vestibular approach (TOETVA) has excellent cosmetic effects and its popularity is increasing worldwide. We present our experience with TOETVA and its short-term outcomes. This study included 110 consecutive patients who underwent TOETVA at a single institution between July 2016 and June 2020. We analyzed clinicopathologic data, short-term postoperative outcomes, and learning curve using cumulative summation (CUSUM) analysis. Of the 110 patients who underwent TOETVA, 101 had malignant disease and 100 (90.9%) underwent lobectomy. The mean age was 39.7 ± 9.7 years, and the mean tumor size was 1.0 ± 0.7 cm (range, 0.3–3.6 cm). Operation time was 168.0 ± 63.4 min for total thyroidectomy, 111.0 ± 27.7 min for lobectomy, and 73.7 ± 18.1 min for isthmusectomy. Five patients (4.5%) experienced transient vocal cord palsy (VCP) and one (0.9%) had permanent VCP. The swallowing impairment index-6 score was 2.18 ± 3.21 at postoperative three months, and 0.97 ± 1.72 at postoperative six months. The learning curve for lobectomy was 58 cases in CUSUM analysis. TOETVA is a safe and feasible approach with an acceptable operation time and a low complication rate. This approach is a surgical option for patients who desire excellent cosmesis.

Abstract
OBJECTIVES Intraoperative neuromonitoring has not been routinely applied in early experience with the transoral endoscopic thyroidectomy vestibular approach (TOETVA). Because the preparation and surgical interventions are much different from conventional thyroidectomies, most endocrine surgeons willing to adapt to TOETVA lack access to information regarding the practice pattern and proficiency in the learning curve. We aimed to investigate the outcomes and to define the learning curve for TOETVA in this study. METHODS A retrospective analysis was used on patients who underwent TOETVA at our hospital between December 2016 and July 2019. The cumulative sum graphic model was used to implement the learning curve as a surrogate for procedural proficiency. RESULTS The 119 patients had a mean age of 44.65 years and a mean body mass index of 22.49 k/m2, including 107 women, 20 thyroiditis, and 106 hemithyroidectomy. The learning curve revealed two phases, an initial (35 cases) and a mature (84 cases) phase, for surgeons based on operation time (144.2 vs. 114.2 min, p = 0.0001). There were more bilateral thyroidectomies (15.5% vs. 0, p = 0.0100), larger indicated nodules (6.06 cm3vs. 3.32 cm3, p = 0.0468), or larger thyroids to resect (16.38 cm3vs. 8.75 cm3, p = 0.0001) in the mature phase. Procedure-related complications decreased significantly in the mature phase in comparison to the initial phase (3.57% vs. 31.43%, p = 0.0001). CONCLUSIONS The learning curve of TOETVA with neuromonitoring is 35 cases. With the accumulation of proficiency, the indications will expand. Step-by-step improvements from the experience of each case can reduce procedure-related complications.

Abstract
PURPOSES To improve the lymph node dissection as well as protect parathyroid gland and recurrent laryngeal nerve, the carbon nanoparticles and intraoperative neuromonitoring were applied in papillary thyroid microcarcinoma surgery. METHODS Carbon nanoparticles and intraoperative neuromonitoring were used in the experimental group, whereas the control group were not. Routine pathological examination was performed. RESULTS The lymph nodes dissected was significantly higher in the experimental group, but the metastatic lymph nodes were not. The number of mistakenly dissected parathyroid gland and postoperative hypoparathyroidism were 3 and 13 in the experimental group respectively, significantly less than 10 and 25 in the control group. The incidences of overall, transient and persistent recurrent laryngeal nerve palsy in the experimental group were 5.5%, 5.5% and 0% respectively, whereas in the control group were 8.6%, 6.9% and 1.7%. CONCLUSIONS Carbon nanoparticles can improve lymph node dissection in papillary thyroid microcarcinoma surgery, and the combination of carbon nanoparticles with intraoperative neuromonitoring can reduce surgical complications and improve patient quality of life.

Abstract
BACKGROUND Outpatient thyroid surgery is gaining popularity as it can reduce length of hospital stay, decrease costs of care, and increase patient satisfaction. There remains a significant variation in the use of this practice including a perceived knowledge gap with regards to the safety of outpatient thyroidectomies and how to go about implementing standardized institutional protocols to ensure safe same-day discharge. This review summarizes the information available on the subject based on existing published studies and guidelines. METHODS This is a scoping review of the literature focused on the safety, efficacy and patient satisfaction associated with outpatient thyroidectomies. The review also summarizes and editorializes the most recent American Thyroid Association guidelines. RESULTS In total, 11 studies were included in the analysis: 6 studies were retrospective analyses, 3 were retrospective reviews of prospective data, and 2 were prospective studies. The relative contraindications to outpatient thyroidectomy have been highlighted, including: complex medical conditions, anticipated difficult surgical dissection, patients on anticoagulation, lack of home support, and patient anxiety toward an outpatient procedure. Utilizing these identified features, an outpatient protocol has been proposed. CONCLUSION The salient features regarding patient safety and selection criteria and how to develop a protocol implementing ambulatory thyroidectomies have been identified and reviewed. In conclusion, outpatient thyroidectomy is safe, associated with high patient satisfaction and decreased health costs when rigorous institutional protocols are established and implemented. Successful outpatient thyroidectomies require standardized preoperative selection, clear discharge criteria and instructions, and interprofessional collaboration between the surgeon, anesthetist and same-day nursing staff.

Abstract
OBJECTIVES Thyroidectomy and parathyroidectomy using the nerve integrity monitor (NIM) require proper placement of the endotracheal tube with electrodes aligned correctly within the larynx. The purpose of this study is to determine the percentage of patients who require positional adjustments of the endotracheal tube prior to beginning surgery and to understand the value of using the GlideScope to assure proper NIM tube placement within the larynx. METHODS This prospective study examines operative data from 297 patients who underwent NIM thyroidectomy and parathyroidectomy. After routine orotracheal intubation by an anesthesiologist and positioning of the patient for surgery, a GlideScope was used to check the position of the tube in 2 planes: depth of tube placement and rotation of the tube within the larynx assuring proper placement of the electromyogram electrodes within the glottis. RESULTS Tube adjustment was required for 66.5% of patients. In 48.1% of cases, tube retraction or advancement to a proper depth was needed. Tube rotation was required for 30.1% of patients, and 11.8% of patients required both adjustment of tube depth and tube rotation to properly align electrodes. CONCLUSIONS After the anesthesiologist places the NIM endotracheal tube, and the patient is positioned for surgery, additional tube adjustment is often needed prior to the start of surgery. The GlideScope is readily available in the operating suite, its use adds little time to the procedure, and assures proper NIM tube placement. The use of the GlideScope is recommended.

Abstract
INTRODUCTION Although intra-operative neuromonitoring (IONM) has become commonly used to identify the recurrent laryngeal nerve (RLN) during thyroid surgeries, its value is still debatable. This study aimed to evaluate the outcomes of thyroid surgery using IONM versus visualisation alone (VA). METHODS We conducted a retrospective analysis of all the open thyroidectomies performed by the otolaryngology department in a tertiary institution in Singapore (Khoo Teck Puat Hospital) from 1 January 2014 to 31 December 2018. There were 301 nerves-at-risk (NAR), 139 in the IONM group and 162 in the VA group. The primary outcome measure was the incidence of RLN injury and the secondary outcome measure was operative duration. RESULTS There were 33 NAR with immediate post-operative RLN injury, of which 7 had permanent (>6 months) injury. There were minor improvements in the respective rates of immediate and permanent injury in the IONM group (7.9%, 0.7%) compared to the VA group (13.6%, 3.8%), but these were not statistically significant (P=0.14, 0.13). The average operative duration of total thyroidectomies in the IONM group was 37 minutes shorter than in the VA group, but the difference was not statistically significant (P=0.40). CONCLUSION The current study shows that the use of intra-operative neuromonitoring shows a tendency towards better RLN outcome and operative duration for total thyroidectomies, but the study may be too small to demonstrate a statistical difference.

Abstract
The recurrent laryngeal nerve (RLN) injuries are frequent complications related to thyroid surgery determining patient complaints and malpractice litigations. In the present work, the authors provide a brief review on the peculiarities of RLN injuries associated with thyroidectomy to highlight the various aspects of medicolegal assessment of causal link between surgery and nerve damage. The characteristics of thyroid disease, the anatomical peculiarities of surgery site and the nerve identification and preservation are factors that mostly influence the liability admission or rejection. In this context, the clinical records are fundamental, representing the most important probative tool. The possibility of having a set of information collected by clinical records, which allows for analysis and comparison to be made regarding the adherence to standards for thyroid surgery, is essential to set any medico-legal deliberation. However, the medicolegal evaluation can be very difficult. The practitioners involved in the medicolegal analysis of patient complaints related to this thyroidectomy complication need an in-depth knowledge of surgical technique, damage prevention activities and related clinical picture. To this must be added an adequate competence in the evaluation of the causal link (relation between the event and the injury and between that injury and the temporary/permanent impairment) based on the rigorous application of the medicolegal method.

Abstract
Purpose The robot-assisted approach for Ivor Lewis esophagectomy offers an enlarged, three-dimensional overview of the intraoperative situs. The vagal nerve (VN) can easily be detected, preserved, and intentionally resected below the separation point of the recurrent laryngeal nerve (RLN). However, postoperative vocal cord paresis can result from vagal or RLN injury during radical lymph node dissection, presenting a challenge to the operating surgeon. Methods From May to August 2019, 10 cases of robot-assisted minimally invasive esophagectomy (RAMIE) with extended 2-field lymphadenectomy, performed at the University Medical Center Mainz, were included in a prospective cohort study. Bilateral intermittent intraoperative nerve monitoring (IONM) of the RLN and VN was performed, including pre- and postoperative laryngoscopy assessment. Results Reliable mean signals of the right VN (2.57 mV/4.50 ms) and the RLN (left 1.24 mV/3.71 ms, right 0.85 mV/3.56 ms) were obtained. IONM facilitated the identification of the exact height of separation of the right RLN from the VN. There were no cases of permanent postoperative vocal paresis. Median lymph node count from the paratracheal stations was 5 lymph nodes. Conclusion IONM was feasible during RAMIE. The intraoperative identification of the RLN location contributed to the accuracy of lymph node dissection of the paratracheal lymph node stations. RLN damage and subsequent postoperative vocal cord paresis can potentially be prevented by IONM.

[PMID: 32543773 PMCID: PMC7528513 DOI: 10.1002/bjs5.50310] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Accepted: 05/11/2020] [Indexed: 12/11/2022] Open
Abstract
Background Intraoperative nerve monitoring (IONM) of the recurrent laryngeal nerve (RLN) predicts the risk of vocal cord palsy (VCP). IONM can be used to adapt the surgical strategy in order to prevent bilateral VCP and associated morbidity. Controversial results have been reported in the literature for the effect of IONM on rates of VCP, and large multicentre studies are required for elucidation. Methods Patients undergoing first‐time thyroidectomy for benign thyroid disease between May 2015 and January 2019, documented prospectively in the European registry EUROCRINE®, were included in a cohort study. The influence of IONM and other factors on the development of postoperative VCP was analysed using multivariable regression analysis. Results Of 4598 operations from 82 hospitals, 3542 (77·0 per cent) were performed in female patients. IONM was used in 4182 (91·0 per cent) of 4598 operations, independent of hospital volume. Postoperative VCP was diagnosed in 50 (1·1 per cent) of the 4598 patients. The use of IONM was associated with a lower risk of postoperative VCP in multivariable analysis (odds ratio (OR) 0·34, 95 per cent c.i. 0·16 to 0·73). Damage to the RLN noted during surgery (OR 24·77, 12·91 to 48·07) and thyroiditis (OR 2·03, 1·10 to 3·76) were associated with an increased risk of VCP. Higher hospital volume correlated with a lower rate of VCP (OR 0·05, 0·01 to 0·13). Conclusion Use of IONM was associated with a low rate of postoperative
VCP.

Abstract
OBJECTIVE To develop evidence-based recommendations for safe, effective, and appropriate thyroidectomy. BACKGROUND Surgical management of thyroid disease has evolved considerably over several decades leading to variability in rendered care. Over 100,000 thyroid operations are performed annually in the US. METHODS The medical literature from 1/1/1985 to 11/9/2018 was reviewed by a panel of 19 experts in thyroid disorders representing multiple disciplines. The authors used the best available evidence to construct surgical management recommendations. Levels of evidence were determined using the American College of Physicians grading system, and management recommendations were discussed to consensus. Members of the American Association of Endocrine Surgeons reviewed and commented on preliminary drafts of the content. RESULTS These clinical guidelines analyze the indications for thyroidectomy as well as its definitions, technique, morbidity, and outcomes. Specific topics include Pathogenesis and Epidemiology, Initial Evaluation, Imaging, Fine Needle Aspiration Biopsy Diagnosis, Molecular Testing, Indications, Extent and Outcomes of Surgery, Preoperative Care, Initial Thyroidectomy, Perioperative Tissue Diagnosis, Nodal Dissection, Concurrent Parathyroidectomy, Hyperthyroid Conditions, Goiter, Adjuncts and Approaches to Thyroidectomy, Laryngology, Familial Thyroid Cancer, Postoperative Care and Complications, Cancer Management, and Reoperation. CONCLUSIONS Evidence-based guidelines were created to assist clinicians in the optimal surgical management of thyroid disease.

Abstract
OBJECTIVE Intraoperative neuromonitoring (IONM) techniques aim to identify and potentially prevent nerve injury during surgeries. Prior studies into the efficacy of recurrent laryngeal nerve (RLN) IONM convey mixed results, with some claiming equivalence between IONM and no monitoring at all. The goal of the current study was to compare continuous RLN monitoring using the laryngeal adductor reflex (LAR) to intermittent RLN monitoring (intermittent IONM) to determine whether continuous monitoring reduces the incidence of intraoperative RLN injury during neck endocrine surgeries. METHODS In this observational, historical case-control study, a historical cohort of patients monitored with intermittent-IONM (group 1, n = 130) were compared to prospectively collected data from consecutive nerves-at-risk monitored continuously with the LAR (LAR-CIONM, group 2, n = 205), at a single center by a single surgeon. The test benefit ratio and relative risk reduction (RRR) for LAR-CIONM over intermittent IONM were calculated. RESULTS For group 1, nine nerves at risk exhibited intraoperative LOS with transient postoperative vocal fold (VF) hypomobility (n = 2) or immobility (VFI, n = 7). For group 2, two nerves at risk (0.98%) had sudden intraoperative LAR LOS following bipolar cautery, resulting in postoperative transient VFI (P = .004). In each group, there was one case of permanent postoperative VFI. The test benefit rate ratio for LAR-CIONM demonstrated a dramatic effect at 5.23, with an RRR of 81.0%. CONCLUSION LAR-CIONM significantly decreased rates of postoperative transient VF paralysis and paresis over intermittent IONM alone (P = .004). Surgeons should be aware of the benefits and limitations of intermittent IONM versus CIONM. Intermittent IONM, although useful in nerve mapping and intraoperative decision making, has minimal benefit for the prevention of nerve injury, whereas CIONM can potentially reduce nerve injury rates and improve patient outcomes.

Abstract
Over the past two decades, intraoperative neural monitoring (IONM) has matured into a powerful risk minimization tool. Meta-analyses of studies, most of which were limited by poor study designs and the sole use of intermittent nerve stimulation, failed to demonstrate superiority of IONM over anatomic recurrent laryngeal nerve (RLN) dissection in the absence of IONM. With the advent of continuous IONM (CIONM), intraoperative nerve electromyographic tracings, registered almost in real time during the operation, accurately predict postoperative vocal fold function when International Neural Monitoring Study Group quality standards are adhered to. CIONM aids in avoiding permanent traction-related nerve injury by urging surgeons to reverse harmful surgical maneuvers. CIONM also forms an integral part in the surgical concept of staged thyroidectomy. Delaying completion surgery on the other side until nerve function has recovered mitigates the risk of bilateral vocal fold palsy. CIONM has greatly furthered our understanding of functional RLN injury, enabling conception of effective risk minimization strategies tailored to the individual patient. The review summarizes the advances of continuous IONM technology that caused a quantum leap in risk minimization for thyroid surgery, shifting current paradigms.

Abstract
Transoral endoscopic thyroidectomy by vestibular approach (TOETVA) is now being performed in increasing frequency and getting more and more attention. TOETVA is carried out through three incisions in the oral vestibular area. Thyroidectomy is performed endoscopically using conventional laparoscopic instruments, an energy based device and neuromonitoring instruments. Intraoperative neuromonitoring is one of the tools of utmost importance, used for navigation and confirmation of the functional integrity of the recurrent nerve during TOETVA. The aim of this study is to give information about the standards and technique of intraoperative neuromonitoring of the recurrent laryngeal nerves during TOETVA procedures. TOETVA is a safe technique with no visible scarring and hence resulting in an excellent cosmetic effect. We believe that neuromonitoring of the recurrent laryngeal nerves also minimizes the risk of nerve damage and is an essential safety component in this technique.

Abstract
Abstract
Background
Remote access and endoscopic thyroid surgery has been gaining popularity because it allows patients to avoid a visible scar in the neck. There is limited data on transoral endoscopic thyroidectomy when it relates to patients with papillary thyroid carcinoma. We aim to evaluate the safety of ipsilateral central compartment dissection for patients who undergo transoral thyroidectomy (thyroidectomy vestibular approach–compartment lymph node dissection).
Patients and Methods
A total of 80 patients who underwent thyroidectomy vestibular approach–compartment lymph node dissection for papillary thyroid carcinoma from June 2015 to September 2016 were identified. Over the same period, a matched cohort of 80 patients who underwent open thyroidectomy with routine ipsilateral central compartment dissection was also identified (Open-compartment lymph node dissection). The two groups were analyzed in terms of patient characteristics, perioperative clinical results and post-operative outcomes.
Results
All patients were female with a mean age of 32-year. There was no difference in mean maximum tumor size and number of lymph nodes dissected. Moreover, there was no difference in average positive lymph nodes between thyroidectomy vestibular approach–compartment lymph node dissection and Open-compartment lymph node dissection (1.48 vs 1.08, P = 0.647). Operative time was longer in the thyroidectomy vestibular approach–compartment lymph node dissection group (193 vs 102 min, P < 0.001). Thyroidectomy specific complications were similar with rates of temporary recurrent laryngeal nerve palsy of 6.3 vs 8.8% and temporary hypocalcemia rates of 2.5 vs 5% in the thyroidectomy vestibular approach–compartment lymph node dissection and Open-compartment lymph node dissection groups, respectively.
Conclusions
Thyroidectomy vestibular approach–compartment lymph node dissection is a feasible and safe option for select patients with papillary thyroid carcinoma who require central node dissection compared with Open-compartment lymph node dissection, and can be a viable alternative for patients wishing to avoid a visible scar.

Abstract
OBJECTIVES In patients who had undergone thyroidectomy in Japan for benign tumor, we determined whether thyroid lobe size correlates with temporary recurrent laryngeal nerve paralysis (T-RLNP). METHODS We retrospectively collected medical record data on usage of intraoperative neuromonitoring, laterality of thyroidectomy, amount of bleeding during surgery, duration of surgery, and whether the surgeon was a board certified otorhinolaryngologist as determined by the Oto-Rhino-Laryngological Society of Japan. Thyroid size was measured in preoperative axial computed tomography (CT) images. Receiver operating characteristic (ROC) curve analysis was used to determine the thyroid size that predicted a high risk of T-RLNP or permanent recurrent laryngeal nerve paralysis (P-RLNP). RESULTS Of the 146 eligible patients identified, 9 (6.2%) developed T-RLNP and 2 (1.4%) developed P-RLNP. The amount of bleeding during thyroidectomy was significantly greater in T-RLNP patients than in P-RLNP patients. Thyroid sizes in CT images were significantly larger in T-RLNP patients compared to patients who did not develop RLNP (referred to hereafter as N-RLNP). ROC analysis revealed that 1.3% of thyroid lobes with an area of less than 1000.0 mm2, and 9.9% of thyroid lobes with an area of greater than 1000.0 mm2 were at risk for T-RLNP. CONCLUSION We presented evidence that thyroid sizes, as measured on preoperative axial CT images, were larger in T-RLNP patients than in N-RLNP patients. Our results indicate a connection between benign thyroid tumor stretch injuries and T-RLNP. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Transoral thyroidectomy is becoming a preferred technique because it has the advantage of not leaving a scar after surgery. However, it is not yet standard because of the anatomic nerve complexity of this oral cavity and difficulty of approach. The aim of this study was to determine the safety zone of a gasless transoral thyroidectomy approach using an anatomical study and to evaluate the efficacy of this approach on clinical application. METHODS Phase 1, twenty unilateral specimens from fresh cadavers underwent staining by the modified Sihler's method to identify nerves around the oral vestibules. Then, the safety zone of the transoral thyroidectomy approach was proposed. Phase 2, a comparative analysis of the clinical outcomes of gasless transoral thyroidectomy through the safety zone versus transcutaneous thyroidectomy approach. RESULTS In phase 1, numerous inferior labial branches diverged from the mental nerve and were distributed across the lower lip. In most cases, the most lateral branch reached almost to the corner of the mouth, whereas a nerve-free area was present at the medial region of the lower lip. The suggested safety zone was presented as a trapezoid shape. In phase 2, there were no significant differences in age, mass size, or complications between the two groups. However, the operation time in the transoral thyroidectomy group was longer than in the transcutaneous group (p = 0.001). CONCLUSIONS Based on the anatomical study, we suggested a safety zone for the gasless transoral thyroidectomy. On application of this safety zone, gasless transoral thyroidectomy is a safe and feasible procedure.

Abstract
Importance Natural orifice transluminal endoscopic surgery thyroidectomy is a novel approach to avoid surgical scars. Objective To compare the safety and outcomes of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) with those of open thyroidectomy (OT). Design, Setting, and Participants This study retrospectively reviewed all TOETVA and OT operations performed from April 1, 2014, through August 31, 2016, at Police General Hospital, Bangkok, Thailand. All patients who underwent TOETVA and patients who underwent OT were included. Exclusion criteria were (1) previous neck surgery, (2) substernal goiter, (3) lymph node or distance metastasis, and (4) suspicious invasion to the adjacent organs. Propensity score matching was conducted to reduce selective bias. Main Outcomes and Measures Operative time, blood loss, and complications related to thyroid surgery. Results Of the 425 patients who underwent transoral endoscopic thyroidectomy (mean age, 35.3 [12.1] years; age range, 16-81 years; 389 [92.2%] female), 422 successfully were treated with the TOETVA; 3 patients were converted to a conventional operation because of bleeding. Twenty-five patients (5.9%) had transient recurrent laryngeal nerve palsy, and 46 (10.9%) had transient hypoparathyroidism. None had permanent recurrent laryngeal nerve palsy or permanent hypoparathyroidism. Three patients (0.7%) had transient mental nerve injury; all cases resolved by 4 months. One patient developed postoperative hematoma treated by OT. Twenty patients (4.7%) had seroma treated by simple aspiration. Operative time was longer for the TOETVA compared with the OT group (100.8 [39.7] vs 79.4 [32.1] minutes, P = 1.61 × 10-10). The mean (SD) visual analog scale score for pain was lower in the TOETVA group (1.1 [1.2] vs 2.8 [1.2], P = 2.52 × 10-38). Estimated mean (SD) blood loss (36.9 [32.4] vs 37.6 [23.1] mL, P = .43) and rate of complications (45 of 216 [20.8%] vs 38 of 216 [17.6%], P = .41) were not significantly different in the TOETVA vs OT group. Conclusions and Relevance The TOETVA was performed as safely as OT, requires only conventional laparoscopic instruments, and avoids incisional scars; thus, the approach may be an option for select patients.

Abstract
Over the last two decades, advances and adaptation of technology have led to a variety of endoscopic thyroidectomy procedures being performed. The drive for extracervical procedures has been predominantly influenced by the desire for improved cosmesis via avoidance of visible scars. Extracervical techniques have shown considerable evolution with approaches that have included transaxillary, breast, postauricular, and transoral routes. There has been a varied evidence base for each of these approaches with regard to technical feasibility, safety, patient satisfaction, and cost-effectiveness. In recent years, robotic-assisted thyroid surgery has gained increased popularity worldwide with the introduction of the da Vinci Robot. Reports of improved postoperative outcomes and patient satisfaction have been in contrast to the financial burden, longer operative time, and increased training required which, to date, have limited widespread application. The aim of this review is to describe the evolution of extracervical procedures including surgical approaches, outcomes, advantages, and disadvantages. Consideration is also given to the future direction of extracervical thyroid surgery with regard to the safety, feasibility, and application of robotic systems.

Abstract
End-stage renal disease is often complicated by the occurrence of secondary and eventually tertiary hyperparathyroidism, characterized by increased parathormone, calcium, and phosphate concentrations. Related symptoms include pruritus and osteodynia, concentration difficulties, and feelings of depression may be present. In the long-term, end-stage renal disease patients with hyperparathyroidism have an increased risk of all-cause and cardiovascular mortality. Among treatment options are vitamin D supplements, phosphate binders, calcimimetics, and surgical parathyroidectomy. Determining the optimal treatment for the individual patient is challenging for nephrologists and endocrine surgeons. This review resumes the pathogenesis of hyperparathyroidism, clinical presentation, required diagnostic work-up, and discusses indications for the available treatment options for patients with secondary and tertiary hyperparathyroidism.

Abstract
Importance Systematic reviews and meta-analyses are considered the best evidence for clinical decision making. Many reviews of intraoperative neuromonitoring (IONM) in thyroidectomy have conflicting results, owing in large part to methodological quality. Objective To assess the methodological quality and the causes of heterogeneous results of systematic reviews that compare routine IONM vs visual identification of the recurrent laryngeal nerve (RLN) in patients undergoing thyroidectomy. Data Sources A systematic search was performed of MEDLINE (PubMed), Embase, the Cochrane Library, LILACS (Literatura Latino Americana e do Caribe em Ciências da Saúde), Web of Science, and Google from January 1, 1968, through June 30, 2018. Data were analyzed from July 17 to November 30, 2018. Study Selection Studies that mentioned performance of a systematic review/meta-analysis during the search period. Data Extraction and Synthesis Data including study characteristics, type of patients, numbers of nerves at risk, and temporary and definitive RLN paralysis by group were extracted. Data about methodological characteristics, type of statistical analysis and summary estimator, endorsement of systematic review/meta-analysis guidelines, heterogeneity, publication bias, funding, conflict of interest, and statistical analysis were also recorded. The methodological quality was measured with the AMSTAR2 (A Measurement Tool to Assess Systematic Reviews) tool by 2 independent evaluators. Main Outcomes and Measures Methodological quality. Results The search identified 13 systematic reviews that included patients who underwent open or minimally invasive thyroidectomy, second operations, and a mixture of low- and high-risk procedures. The mean compliance with the AMSTAR2 overall criteria was 53% (range, 11%-83%); with critical criteria, 71% (range, 50%-94%). The percentage of nerves at risk from RCTs was 4.8%. The mean (SD) crude rate of definitive RLN paralysis was 0.81% (0.22%; median, 0.75% [range, 0.53%-1.30%]) in the monitoring group and 1.14% (0.56%; median, 0.96% [range, 0.57%-2.56%]) in the control group. Conclusions and Relevance A substantial number of systematic reviews of IONM in thyroidectomy have conflicting results, but their mean methodological quality is critically low. Design of a systematic review should comply with methodological standards and recommendations to offer relevant and practical information for decision making.

Abstract
BACKGROUND For selected patients, endoscopic thyroidectomy via the oral-vestibular approach (ETOVA) can be used to achieve a very good esthetic effect. This study aimed to assess the learning curve for ETOVA and identify improvements. PATIENTS AND METHODS This retrospective study evaluated the outcomes of 101 patients who underwent ETOVA by surgeons A and B. The patients were classified according to whether they had undergone surgery during the primary or advanced stage of the learning curve, respectively. Proficiency with the procedure in various types of cases and the operation time, operative blood loss, hospital stay length, and postoperative complications were analyzed. RESULTS In total, 56 and 45 patients were treated by surgeons A and B, respectively. For both surgeons, the operation times decreased considerably after 20 cases. Statistically significant differences with respect to stage were observed in terms of operation time (P<0.05) and drainage tube reservation (P<0.05). By contrast, significant differences were not observed between stages in terms of operative blood loss (P>0.05) or postoperative hospital stay length (P>0.05). The total postoperative complication rate was low and comparable with that of open surgery. CONCLUSIONS The specific learning curve identified for ETOVA suggests that surgeons with sufficient endoscopic surgery experience could achieve a stable proficiency after ∼20 cases. A standardized training program and exposure to more cases would reduce the learning curve.

Abstract
BACKGROUND Injuries to the recurrent inferior laryngeal nerve (RILN) remain one of the major post-operative complications after thyroid and parathyroid surgery. Damage to this nerve can result in a temporary or permanent palsy, which is associated with vocal cord paresis or paralysis. Visual identification of the RILN is a common procedure to prevent nerve injury during thyroid and parathyroid surgery. Recently, intraoperative neuromonitoring (IONM) has been introduced in order to facilitate the localisation of the nerves and to prevent their injury during surgery. IONM permits nerve identification using an electrode, where, in order to measure the nerve response, the electric field is converted to an acoustic signal. OBJECTIVES To assess the effects of IONM versus visual nerve identification for the prevention of RILN injury in adults undergoing thyroid surgery. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, ICTRP Search Portal and ClinicalTrials.gov. The date of the last search of all databases was 21 August 2018. We did not apply any language restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing IONM nerve identification plus visual nerve identification versus visual nerve identification alone for prevention of RILN injury in adults undergoing thyroid surgery DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts for relevance. One review author carried out screening for inclusion, data extraction and 'Risk of bias' assessment and a second review author checked them. For dichotomous outcomes, we calculated risk ratios (RRs) with 95% confidence intervals (CIs). For continuous outcomes, we calculated mean differences (MDs) with 95% CIs. We assessed trials for certainty of the evidence using the GRADE instrument. MAIN RESULTS Five RCTs with 1558 participants (781 participants were randomly assigned to IONM and 777 to visual nerve identification only) met the inclusion criteria; two trials were performed in Poland and one trial each was performed in China, Korea and Turkey. Inclusion and exclusion criteria differed among trials: previous thyroid or parathyroid surgery was an exclusion criterion in three trials. In contrast, this was a specific inclusion criterion in another trial. Three trials had central neck compartment dissection or lateral neck dissection and Graves' disease as exclusion criteria. The mean duration of follow-up ranged from 6 to 12 months. The mean age of participants ranged between 41.7 years and 51.9 years.There was no firm evidence of an advantage or disadvantage comparing IONM with visual nerve identification only for permanent RILN palsy (RR 0.77, 95% CI 0.33 to 1.77; P = 0.54; 4 trials; 2895 nerves at risk; very low-certainty evidence) or transient RILN palsy (RR 0.62, 95% CI 0.35 to 1.08; P = 0.09; 4 trials; 2895 nerves at risk; very low-certainty evidence). None of the trials reported health-related quality of life. Transient hypoparathyroidism as an adverse event was not substantially different between intervention and comparator groups (RR 1.25; 95% CI 0.45 to 3.47; P = 0.66; 2 trials; 286 participants; very low-certainty evidence). Operative time was comparable between IONM and visual nerve monitoring alone (MD 5.5 minutes, 95% CI -0.7 to 11.8; P = 0.08; 3 trials; 1251 participants; very low-certainty evidence). Three of five included trials provided data on all-cause mortality: no deaths were reported. None of the trials reported socioeconomic effects. The evidence reported in this review was mostly of very low certainty, particularly because of risk of bias, a high degree of imprecision due to wide confidence intervals and substantial between-study heterogeneity. AUTHORS' CONCLUSIONS Results from this systematic review and meta-analysis indicate that there is currently no conclusive evidence for the superiority or inferiority of IONM over visual nerve identification only on any of the outcomes measured. Well-designed, executed, analysed and reported RCTs with a larger number of participants and longer follow-up, employing the latest IONM technology and applying new surgical techniques are needed.

Abstract
BACKGROUND Transoral thyroidectomy is a kind of "natural orifice transluminal endoscopic surgery (NOTES)" which is now being performed in increasing frequency. However, the safety and feasibility have not been concluded yet. MATERIALS AND METHODS A systemic literature search was performed in Pubmed, Cochrane, and Embase databases to identify all studies written in English and published up to April 2017. The keywords used were "transoral endoscopic," "transoral robotic," "oral vestibular endoscopic," and "oral vestibular robotic" combined with "thyroidectomy" or "thyroid surgery." RESULTS Ten articles containing 211 cases matched the review criteria. The weighted average operative time was 119.9 minutes with an average intraoperative blood loss of 35.5 mL while the weighted average length of hospital stay was 4.0 days. The overall conversion rate to open surgery was 1.9%. An overall incidence rate of temporary hypoparathyroidism was 7.1%, temporary recurrent laryngeal nerve injury was 4.3%, whereas of mental nerve palsy was 4.3%. CONCLUSIONS According to those reviewed literatures, we can conclude that transoral thyroidectomy is safe and feasible in well-selected patients and offers good perioperative and postoperative outcomes.

Abstract
BACKGROUND The aim of this study was to evaluate the diagnostic accuracy of intraoperative neuromonitoring (IONM) in predicting postoperative nerve function during thyroid surgery and its consequent ability to assist the surgeon in intraoperative decision making. MATERIALS AND METHODS A total of 2365 consecutive patients were submitted to thyroidectomy by the same surgical team. Group A included 1356 patients (2712 nerves at risk) in whom IONM was utilized, and Group B included 1009 patients (2018 nerves at risk) in whom IONM was not utilized. RESULTS In Group A, loss of signal (LOS) was observed in 37 patients; there were 29 true positive, 1317 true negative, 8 false positive, and 2 false negative cases. Accuracy was 99.3%, positive predictive value was 78.4%, negative predictive value was 99.8%, sensitivity was 93.6%, and specificity was 99.4%. A total of 29 (2.1%) cases of unilateral paralysis were observed, 23 (1.7%) of which were transient and 6 (0.4%) of which were permanent. Bilateral palsy was observed in two (0.1%) cases requiring a tracheostomy. In Group A, 31 (2.3%) injuries were observed, 25 (1.8%) of which were transient and 6 (0.4%) of which were permanent. In Group B, 26 (2.6%) unilateral paralysis cases were observed, 20 (2%) of which were transient and 6 (0.6%) of which were permanent; bilateral palsy was observed in 2 (0.2%) cases. In Group B, 28 (2.8%) injuries were observed, 21 (2.1%) of which were transient and 7 (0.7%) of which were permanent. Differences between the two groups were not statistically significant. CONCLUSIONS Our results show that IONM has a very high sensitivity and negative predictive value, but also good specificity and positive predictive value. For these reasons, in selected patients with LOS, the surgical strategy should be reconsidered. However, patients need to be informed preoperatively about potential strategy changes during the planned bilateral surgery. Future larger and multicenter studies are needed to confirm the benefits of this therapeutic strategy.

Abstract
INTRODUCTION The Transoral Neck Surgery (TONS) Study Group was established at the 1st International Thyroid NOTES Conference in February 2016 with the intention of standardizing and refining thyroid NOTES techniques, including both transoral endoscopic and robotic thyroidectomy approaches. Herein, the authors report the modification of indications, preparation, and step-by-step explanations for operative techniques, as well as results and postoperative care for transoral endoscopic thyroidectomy vestibular approach (TOETVA). METHODS Between February 2015 and December 2015, a total of 200 patients comprising 8 males (4%) and 192 females (96%) underwent TOETVA using 3 laparoscopic ports inserted at the oral vestibule. Of these patients, 111 presented with single thyroid nodules (55.5%), while 66 patients had multinodular goiters (33%), 12 had Graves' disease (6%) and 11 had papillary microcarcinoma (5.5%). The CO2 insufflation pressure was maintained at 6 mmHg. Each surgery was performed using laparoscopic instruments and ultrasonic devices. RESULTS TOETVA was performed on 200 consecutive patients. No conversion to conventional open surgery was necessary. Average tumor size was 4.1 ± 1.78 cm (1-10 cm). Median operative time was 97 ± 40.5 min (45-300 min). Median blood loss was 30 ± 46.25 mL (6-300 mL). Mean visual analog scale measurements were 2.41 ± 2.04 (2-7), 1.17 ± 1.4 (0-5), and 0.47 ± 0.83 (0-3) on the first, second, and third days, respectively. Temporary hoarseness and hypoparathyroidism occurred in 8 patients (4%) and 35 patients (17.5%), respectively. No permanent hoarseness or hypoparathyroidism occurred. Mental nerve injury occurred in 3 patients (1.5%). One patient (0.5%) developed a post-operative hematoma that required open surgery. No infection was identified. CONCLUSION TOETVA was shown to be safe and feasible with a reasonable surgical duration and minimal pain scores. This approach shows promise for those patients who are motivated to avoid a neck scar.

Abstract
AIM The purpose of this paper is to provide a forensic profile framework of neuromonitoring in thyroid surgery, regarding the information given to the patient and its classification as part of professional liability in the event of recurrent injury. METHOD Evaluation and reflections on the required behaviour of the surgeon on providing details on the operation before the informed consent is given and to outline the possible legal implications regarding professional liability as a result of recurrent injury. In particular, if it is an obligation to inform the patient about using this method and if it is possible for the surgeon to freely choose whether to employ this method, which is still burdened by a certain percentage of error and for that reason it cannot be defined a "standard of care". RESULTS To recognize neuromonitoring the role of standard of care in surgery of the thyroid means attribute a role of method able to avoid the surgeon to cause iatrogenic damage to the laryngeal nerve. For the foregoing reasons that is not true, determining false positives and false negatives, and this can be a double edged sword for the surgeon. CONCLUSIONS Although the progress in the field of thyroid surgery made in the last decade, currently there is no scientific reassuring evidence to completely avoid the possibility of producing an iatrogenic lesion of the laryngeal nerve. Information given to the patient prior to surgery should respect the requirements of completeness, freedom and honesty in order to allow the patient to self-determination.

Abstract
INTRODUCTION The Transoral Neck Surgery (TONS) Study Group was established at the 1st International Thyroid NOTES Conference in February 2016 with the intention of standardizing and refining thyroid NOTES techniques, including both transoral endoscopic and robotic thyroidectomy approaches. Herein, the authors report the modification of indications, preparation, and step-by-step explanations for operative techniques, as well as results and postoperative care for transoral endoscopic thyroidectomy vestibular approach (TOETVA). METHODS Between February 2015 and December 2015, a total of 200 patients comprising 8 males (4%) and 192 females (96%) underwent TOETVA using 3 laparoscopic ports inserted at the oral vestibule. Of these patients, 111 presented with single thyroid nodules (55.5%), while 66 patients had multinodular goiters (33%), 12 had Graves' disease (6%) and 11 had papillary microcarcinoma (5.5%). The CO2 insufflation pressure was maintained at 6 mmHg. Each surgery was performed using laparoscopic instruments and ultrasonic devices. RESULTS TOETVA was performed on 200 consecutive patients. No conversion to conventional open surgery was necessary. Average tumor size was 4.1 ± 1.78 cm (1-10 cm). Median operative time was 97 ± 40.5 min (45-300 min). Median blood loss was 30 ± 46.25 mL (6-300 mL). Mean visual analog scale measurements were 2.41 ± 2.04 (2-7), 1.17 ± 1.4 (0-5), and 0.47 ± 0.83 (0-3) on the first, second, and third days, respectively. Temporary hoarseness and hypoparathyroidism occurred in 8 patients (4%) and 35 patients (17.5%), respectively. No permanent hoarseness or hypoparathyroidism occurred. Mental nerve injury occurred in 3 patients (1.5%). One patient (0.5%) developed a post-operative hematoma that required open surgery. No infection was identified. CONCLUSION TOETVA was shown to be safe and feasible with a reasonable surgical duration and minimal pain scores. This approach shows promise for those patients who are motivated to avoid a neck scar.
