Latex-injected, non-decapitated, saturated salt method-embalmed cadaver technique development and application as a head and neck surgery training model.

Published cerebrovascular injection techniques have mostly used decapitated, fresh cadavers or heads embalmed with 10% formaldehyde. There have been no reports using vascular-injected cadavers for head and neck surgical training models or using vascular injections in saturated salt method-embalmed cadavers. Thus, we performed vascular labeling of five saturated salt method-embalmed cadavers without decapitation. Latex mixed with red ink was injected into the common carotid artery via a 3D-printed vascular adapter. The injection force was provided by a peristaltic pump. Thyroidectomy, submandibular gland excision, neck dissection, parotidectomy, and mandibulotomy were performed on both sides of each cadaver (n = 10). The consistency of the cadavers was softer than fresh ones. Subcutaneous tissues were well preserved, and muscles were moist and elastic. Five physicians graded the resemblance of the heads and necks of the latex-injected, saturated salt method-embalmed, non-decapitated of five cadavers compared to living humans using a Likert scale from 0 (no resemblance) to 5 (maximum resemblance). Fifty-two percent of the head and neck region resemblance scale ratings were four or five. Although the cadavers were practical for head and neck surgical simulations, the brain parenchyma was only partially preserved and unsuitable for use. The most distal arterial branches reached by the injected latex were measured. The external caliber of the smallest vessels reached were lacrimal arteries (mean caliber ± SD, 0.04 ± 0.04 mm; 95% CI [0, 0.09]). There were no significant differences in the mean caliber of the smallest vessels reached between the left- and right-sided arterial branches (all p < 0.05).

Transoral endoscopic vestibular approach for thyroidectomy and parathyroidectomy - From promise to practice.

OBJECTIVES: To describe the evolution and recent series on transoral endoscopic vestibular approach thyroidectomy and parathyroidectomy (TOET/PVA). DATA SOURCES: PubMed, Google Scholar. REVIEW METHODS: Review of the available English literature. RESULTS: TOET/PVA may offer several advantages over other remote access thyroidectomy approaches and has been adopted by many centers worldwide with excellent success rates. Indications include benign disease and early thyroid cancer patients. Complication rate is comparable to the trans-cervical approach. The suggested framework has been validated in recent studies and its feasibility confirmed. CONCLUSION: TOET/PVA has now been used to treat thousands of patients worldwide due to low cost, short learning curve and excellent cosmetic outcomes. Further studies will be necessary to demonstrate oncologic non-inferiority and also the true value that is added by the approach.

In-Practice Endocrine Surgery Fellowship: A Novel Training Model.

OBJECTIVE: Endocrine surgery is an expanding field within otolaryngology. We hypothesized that a novel endocrine surgery fellowship model for in-practice otolaryngologists could result in expert-level training. STUDY DESIGN: Qualitative clinical study with chart review. SETTING: Urban community practice and academic medical center. METHODS: Two board-certified general otolaryngologists collaborated with a senior endocrine surgeon to increase their endocrine surgery expertise between March 2015 and December 2017. The senior surgeon provided intensive surgical training to both surgeons for all of their endocrine surgeries. Both parties collaborated with endocrinology to coordinate medical care and receive referrals. All patients undergoing endocrine surgery during this time frame were reviewed retrospectively. RESULTS: A total of 235 endocrine surgeries were performed. Of these, 198 thyroid surgeries were performed, including 98 total thyroidectomies (48%), 90 lobectomies (45%), and 10 completion thyroidectomies (5%). Sixty cases demonstrated papillary thyroid carcinoma, 11 follicular thyroid carcinoma, and 4 medullary thyroid carcinoma. Neck dissections were performed in 14 of the cases. Thirty-seven parathyroid explorations were performed. There were no reports of permanent hypoparathyroidism. Thirteen patients (5.5%) developed temporary hypoparathyroidism. Six patients (2.5%) developed postoperative seroma. Three patients (1.3%) developed postoperative hematomas requiring reoperation. One patient (0.4%) developed permanent vocal fold paralysis, and 3 patients (1.3%) had temporary dysphonia. Thirty-five of 37 (94.5%) parathyroid explorations resulted in biochemical resolution of the patient's primary hyperparathyroidism. CONCLUSION: This is the first description of a new fellowship paradigm where a senior surgeon provides fellowship training to attending surgeons already in practice.

SimLife model: introducing a new teaching device in endocrine surgery simulation.

To evaluate the validity and reliability of an innovative training model for endocrine surgical procedures. A simulator training model for endocrine procedures (SimLife) was developed at an academic center. The model consisted of a realistic operating environment with a coherent simulated patient dynamized by pulsatile vascularization with simulated blood warmed to 37 °C, and ventilation. Training sessions were designed for adrenal and thyroid surgery, as well as neck dissection. The primary outcome of interest was to evaluate learners' performance and satisfaction. Learners' performance was evaluated based on a scoring scale that followed the Downing method for the assessment of competency. While learners' satisfaction was evaluated using a Likert scale of 1 to 10 on four items (ease of learning, anatomic correspondence of landmarks, realism, and overall satisfaction). Participants were engaged in 32 training sessions. These included 24 adrenalectomies (conventional and laparoscopic both transabdominal and posterior), and 4 thyroid lobectomies with concomitant functional lateral compartment neck dissection. competency scores were procedure-specific addressing specific core components of a given procedure. Learners' performance scored above average in all procedures evaluated. Satisfaction scores for the specified four items ranged between 8.43 (SD 0.87) and 8.89 (SD 0.96). No major events were reported for the adrenalectomies, while only one jugular vein injury occurred during neck dissection. SimLife is a hyper-realistic training model that allows for satisfactory acquisition of skills and the evaluation of performance progression. It has the potential to become a cornerstone in specialized surgical training.

Minimally Invasive Approaches for Thyroid Surgery-Pitfalls and Promises.

PURPOSE OF REVIEW: To provide an overview of the feasibility and safety of current minimally invasive remote-access approaches for thyroid surgery, in view of the amounting new challenges and paradigm shifts in the management of thyroid pathologies. RECENT FINDINGS: Over the past two decades, several remote-access approaches for thyroid surgery have been developed to improve cosmesis; however, none has been widely adopted extensively in the Western world. The recently emerged transoral endoscopic thyroidectomy via vestibular approach (TOETVA) is the only true minimally invasive approach, completely avoiding skin incisions. It has a relatively short learning curve, midline surgical view, accessible surgical equipment, and relatively broad inclusion criteria with promising surgical outcomes as reported to date. TOETVA has proven to be safe and feasible for carefully selected patients. Further experience and long-term follow-up are needed to define the added value of TOETVA except for improved cosmetic outcome.

Surgical impact of a dedicated endocrine surgeon on an academic otolaryngology department.

OBJECTIVES: Endocrine surgery is emerging as a dedicated subspecialty in otolaryngology. We assess the impact of an endocrine surgeon on an academic otolaryngology department's thyroid and parathyroid surgery volume. METHODS: A retrospective study of overall endocrine caseloads and resident case logs at a single academic center in the Midwest was performed. All thyroid and parathyroid cases performed by the otolaryngology department at an academic center from 2011 to 2017 were reviewed. In September 2012, an otolaryngologist who had completed an American Head and Neck Society endocrine surgery fellowship joined the faculty. The volume of endocrine surgery performed by the residents was also analyzed. Comparison of means and linear regression models were performed. RESULTS: From 2011 to 2012, the department performed a mean of 77 thyroid and 11.5 parathyroid surgeries annually. After the endocrine surgeon joined the department, this increased to an average of 212.8 thyroidectomies (P < 0.01) and 72.4 parathyroidectomies (P < 0.01) a year. The head and neck surgeons and generalists still performed an average of 42.4 thyroidectomies and 2.6 parathyroidectomies a year. For graduating residents, the average number of thyroid/parathyroid cases increased from 42.5 in 2012 to 151 in 2016. CONCLUSION: The addition of a fellowship-trained endocrine surgeon substantially increased the thyroid and parathyroid surgical volume of the otolaryngology department. Importantly, generalists and head and neck surgeons in the department continued to perform a significant number of these cases. Departments seeking similar surgical growth and expanded resident experience may consider the value of engaging a dedicated endocrine surgeon. LEVEL OF EVIDENCE: 4 Laryngoscope, 130:832-835, 2020.

Robotic thyroidectomy via bilateral axillo-breast approach: Experience and learning curve through initial 220 cases.

OBJECTIVE: This study is aim to summarize the experience of robotic thyroidectomy via bilateral axillo-breast approach of our center and also to find out the learning curve of this technique. METHODS: In total 220 initial patients who have undergone robotic thyroidectomy via bilateral axillo-breast approach from May 2015 to September 2017 were involved in this study. The data of operation time, clinical characteristics, surgical outcomes and oncological outcomes were collected. The moving average method is use to explore the learning curve. RESULTS: All patients had undergone robotic thyroidectomy successfully without conversion to other surgical approaches. The mean age of the enrolled subjects was 34.4 ± 7.8 years old, while the sex ratio (male/female) was 38/182. There were 50 benign tumor cases and 170 malignant tumor cases. The mean total operation time was 105.3 ± 37.6 min. Lymph node metastasis was observed in 61 (35.9%) patients. The mean retrieved lymph node count was 5.1 ± 3.8 while the mean metastatic lymph node count was 0.7 ± 1.5. The operation time decreased significantly after about 30-35 cases and formed the plateau. After 80 cases, the operation time significantly decreased again. CONCLUSION: For skilled endocrine surgeons, robotic thyroidectomy has proved to be safe and feasible, which could be applied extensively in patients strictly selected in high-volume centers, with a relatively short learning curve of about 30-35 cases. While the surgeons getting more experienced, this technique would be more efficient.

Application of the healthcare failure mode and effects analysis system to reduce the incidence of posture syndrome of thyroid surgery.

This study aimed to investigate the application of the healthcare failure mode and effect analysis (HFMEA) to reduce the incidence of posture syndrome of thyroid surgery (PSTS).Subjects before (n = 78, July 2017-December 2017) and after (n = 114, January 2018-June 2018) HFMEA implementation (The Second Hospital of Nanjing, Nanjing University of Chinese Medicine) were selected. The training for PSTS was optimized using HFMEA.The occurrence of PSTS was reduced from 59% to 18% after HFMEA (P < .001). Symptoms of pain and nausea and vomiting were also decreased after HFMEA (all P < .001). The critical thinking ability of 34 medical personnel to evaluate the reduction of thyroid postoperative posture syndrome increased from 246 ±â€Š19 to 301 ±â€Š14 (P < .001) after HFMEA.HFMEA was used to create preoperative posture training procedures for PSTS, bedside cards for training, innovative preoperative posture training equipment, and a diversified preoperative posture training health education model.

Training in endocrine surgery.

BACKGROUND/PURPOSE: In Europe, the Division of Endocrine Surgery (DES) determines the number of operations (thyroid, neck dissection, parathyroids, adrenals, neuroendocrine tumors of the gastro-entero-pancreatic tract (GEP-NETs)) to be required for the European Board of Surgery Qualification in (neck) endocrine surgery. However, it is the national surgical boards that determine how surgical training is delivered in their respective countries. There is a lack of knowledge on the current situation concerning the training of surgical residents and fellows with regard to (neck) endocrine surgery in Europe. METHODS: A survey was sent out to all 28 current national delegates of the DES. One questionnaire was addressing the training of surgical residents while the other was addressing the training of fellows in endocrine surgery. Particular focus was put on the numbers of operations considered appropriate. RESULTS: For most of the operations, the overall number as defined by national surgical boards matched quite well the views of the national delegates even though differences exist between countries. In addition, the current numbers required for the EBSQ exam are well within this range for thyroid and parathyroid procedures but below for neck dissections as well as operations on the adrenals and GEP-NETs. CONCLUSIONS: Training in endocrine surgery should be performed in units that perform a minimum of 100 thyroid, 50 parathyroid, 15 adrenal, and/or 10 GEP-NET operations yearly. Fellows should be expected to have been the performing surgeon of a minimum of 50 thyroid operations, 10 (central or lateral) lymph node dissections, 15 parathyroid, 5 adrenal, and 5 GEP-NET operations.

Surgical training in video-assisted neck surgery-based thyroidectomy using fresh frozen human cadavers.

Endoscopic surgery has been introduced in various surgical fields. Endoscopic surgery requires different skills from open surgery due to the restricted surgical field and difficulty in identifying anatomical structures from certain viewpoints. Therefore, surgeons need to undergo sufficient surgical training before performing such surgery in the clinical setting. We examined the utility of fresh frozen human cadavers for surgical training aimed at introducing video-assisted neck surgery (VANS) at our department. First, we performed surgical training using fresh human cadavers four times. Next, we performed hemi-thyroidectomy with VANS in 5 clinical patients. After the cadaver training and the actual surgery, the surgeons evaluated each step of the surgical procedure using a 3-point scale. In the cadaver training, the scores for steps : creation of a subcutaneous tunnel and lifting up the skin flap and pre-thyroid muscles were higher than other steps. And a tracheal injury occurred as a complication. However, we were able to recognize anatomical structures under the endoscopic view. And it was also useful for confirming the role of surgical staff and simulating the placement of surgical equipment. Surgical training using fresh frozen human cadavers was effective at introducing a new surgical method. J. Med. Invest. 66 : 293-296, August, 2019.

The Learning Curve for Surgeons Regarding Endoscopic Thyroidectomy via the Oral-vestibular Approach.

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.

Bilateral Axillo-Breast Approach to Endoscopic Thyroidectomy in a Porcine Model.

Traditional surgical training methods to teach young doctors have changed because of the emergence of animal models. The present article summarizes a protocol for bilateral axillo-breast approach (BABA) endoscopic thyroidectomy in a pig model. All procedures were approved by the local ethics committee and the pigs were anesthetized by a veterinarian. Formation of the flap involved skin marking, hydrodissection, blunt dissection and, finally, trocar insertion. BABA endoscopic thyroidectomy is performed by midline division, identification of the thyroid, thyroidectomy and, finally, surveillance of bleeding. Four cases of endoscopic thyroidectomy using porcine models were performed using the BABA approach. The mean weight of the pigs was 60 kg, and the mean operation time was 74.3 minutes. All surgeries were completed without complications. Surgical training for BABA endoscopic thyroidectomy using a porcine model is a valuable education method for young surgeons who need practice before performing surgery on human patients.

A High-Definition Video Teaching Module for Thyroidectomy Surgery.

OBJECTIVE: With the changing landscape of postgraduate surgical education to competency-based curricula, there emerges a need for alternative forms of training. Video teaching modules have been shown to be effective tools in surgical education, complementing traditional postgraduate curricula. There is a lack of validated modules described in the literature, specifically for teaching thyroidectomy. The primary objective of this study was to develop and validate a high definition video-based teaching module instructing thyroidectomy surgery to Otolaryngology-Head and Neck Surgery trainees. DESIGN: This prospective study included intermediate to senior Otolaryngology-Head and Neck Surgery residents. Each participant first performed a thyroid lobectomy, serving as the initial assessment. After a washout period of at least 3 weeks, each participant was given the teaching module. The 15-minute module was developed using a 3-camera system and detailed a step-by-step approach to the surgery. After exposure to the module, each trainee performed the same procedure. Recordings of both procedures were deidentified and reviewed by a blinded, independent evaluator. Scoring was done using the Observational Clinical Human Reliability Assessment (OCHRA) system. SETTING: University of Alberta Hospital and Royal Alexandra Hospital, Edmonton, Alberta, Canada. PARTICIPANTS: A total of 6 intermediate to senior Otolaryngology-Head and Neck Surgery residents entered and completed the study. RESULTS: The mean error rate was 8.8 errors per procedure before module exposure and 4.5 errors per procedure after exposure, representing a 49% decrease in error occurrence (p < 0.05). The mean staff takeover event rate was 10.5 takeovers per procedure prior to module exposure and 5.0 takeovers per procedure after exposure, representing a 52% decrease in error occurrence (p < 0.05). CONCLUSION: High-definition video teaching modules are a useful complement to traditional surgical training. In a climate where new innovations for teaching thyroid surgery are needed, properly constructed and validated video teaching modules can serve as important tools in supplementing traditional surgical training.

Development of a surgical training model for bilateral axillo-breast approach robotic thyroidectomy.

BACKGROUND: Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) is an excellent surgical method, being oncologically safe and with anatomic views similar to those of open surgery. BABA RT, however, requires training and a learning curve for proficiency. We evaluated the educational effectiveness of a surgical training model for BABA RT, comparing objective BABA scores with scores on the da Vinci Skills Simulator (dVSS). METHODS: Medical students, surgical residents, and surgical fellows performed structured tasks with the BABA training model and dVSS under the same conditions. All tasks were videotaped. BABA scores were compared with dVSS scores and with objective evaluation scores (GEARS and OSATS). RESULTS: Eight medical students, ten surgical residents, and eight surgical fellows participated in this study. The educational effect of BABA training improved from one to two (p < 0.001), two to three (p = 0.003), and one to three (p < 0.001) procedures. Statistically significant differences were found when students were compared with residents (p = 0.025) and fellows (p < 0.001) in the BABA training model, and between students and fellows (p = 0.004) in dVSS. BABA scores showed similar distribution patterns in the three groups to GEARS and OSATS scores (p < 0.001 each). CONCLUSIONS: The BABA training model is an excellent educational tool for surgical residents and surgical fellows to learn and practice BABA RT. Assessment by BABA score yielded objective results comparable to those of traditional scoring methodologies.

Measuring Decision-Making During Thyroidectomy: Validity Evidence for a Web-Based Assessment Tool.

BACKGROUND: Errors in judgment during thyroidectomy can lead to recurrent laryngeal nerve injury and other complications. Despite the strong link between patient outcomes and intraoperative decision-making, methods to evaluate these complex skills are lacking. The purpose of this study was to develop objective metrics to evaluate advanced cognitive skills during thyroidectomy and to obtain validity evidence for them. METHODS: An interactive online learning platform was developed ( www.thinklikeasurgeon.com ). Trainees and surgeons from four institutions completed a 33-item assessment, developed based on a cognitive task analysis and expert Delphi consensus. Sixteen items required subjects to make annotations on still frames of thyroidectomy videos, and accuracy scores were calculated based on an algorithm derived from experts' responses ("visual concordance test," VCT). Seven items were short answer (SA), requiring users to type their answers, and scores were automatically calculated based on their similarity to a pre-populated repertoire of correct responses. Test-retest reliability, internal consistency, and correlation of scores with self-reported experience and training level (novice, intermediate, expert) were calculated. RESULTS: Twenty-eight subjects (10 endocrine surgeons and otolaryngologists, 18 trainees) participated. There was high test-retest reliability (intraclass correlation coefficient = 0.96; n = 10) and internal consistency (Cronbach's α = 0.93). The assessment demonstrated significant differences between novices, intermediates, and experts in total score (p < 0.01), VCT score (p < 0.01) and SA score (p < 0.01). There was high correlation between total case number and total score (ρ = 0.95, p < 0.01), between total case number and VCT score (ρ = 0.93, p < 0.01), and between total case number and SA score (ρ = 0.83, p < 0.01). CONCLUSION: This study describes the development of novel metrics and provides validity evidence for an interactive Web-based platform to objectively assess decision-making during thyroidectomy.

Resident and fellow participation in Thyroid and Parathyroid surgery: an ACS-NSQIP clinical outcomes analysis.

BACKGROUND: The effect of decreased overall hours of training in surgical specialties is still being examined. Of particular interest is the safety of patients undergoing surgeries with trainee surgeons. The aim of this study was to identify if there were significant differences in outcomes of patients undergoing commonly performed thyroid and parathyroid surgeries when trainees were involved. MATERIALS AND METHODS: Postoperative complication rates, length of stay (LOS), and total operation time (OT) data were gathered from the American College of Surgeons National Surgical Quality Improvement Project database. The cases were identified by CPT code and were divided based on the training level of the participating resident surgeon: Junior (postgraduate year [PGY] 1-2), senior (PGY 3-5), fellow (PGY >5), as well as an attending-only group where no resident was present. We compared the clinical outcomes, LOS, and OT in each trainee group to the attending-only group as the reference. RESULTS: A total of 84,711 cases were identified of which 45.33% involved trainee participation. Odds ratios (ORs) and 95% confidence interval for overall, neurologic, and bleeding complications were calculated. No difference in the odds of overall patient complications or neurologic complications was observed. A decrease in the odds of bleedings complications when a junior or senior trainee was present was observed. Overall complications in operations including a junior trainee (PGY 1-2) had an OR of 1.04 (0.85, 1.29), a senior trainee (PGY 3-5) had an OR of 1.00 (0.89, 1.13), and a fellow had an OR of 0.98 (0.74, 1.31). Mean OT was found to be significantly different between attending only and junior and senior trainees. There was no significant difference in OT between fellows and attending only. LOS did not meaningfully differ across groups. CONCLUSIONS: In three commonly performed thyroid and parathyroid operations, there is not an increased overall or neurologic complication odds when a surgical trainee is involved; there are decreased odds of a bleeding complication.

Single-incision endoscopic thyroidectomy by the axillary approach with gas inflation for the benign thyroid tumor: retrospective analysis for a single surgeon's experience.

BACKGROUND: Trans-axillary endoscopic thyroid surgery offers the advantage of a good cosmetic outcome; however, it requires a wider dissection field compared to the other endoscopic approaches or open surgery. Therefore, it might cause severe postoperative pain occasionally. To reduce the dissection field required, we perform trans-axillary single-incision endoscopic thyroidectomy (SIET) with gas inflation. The aim of this study was to present a single surgeon's experience with SIET and to investigate the learning curve of SIET. METHODS: Between June 2009 and September 2014, a total of 105 patients who underwent hemithyroidectomy for benign thyroid tumor via an SIET procedure were included in the present study. All of the procedures were performed by the same surgeon. Each patient's operative outcomes were collected and retrospectively analyzed. The cumulative summation (CUSUM) analysis was used to assess the learning curve of SIET. RESULTS: No mortality or serious morbidity was observed during the study period. The adverse postoperative outcomes included wound hematoma (2 cases; 1.9 %), transient skin paresthesia (5 cases; 4.76 %), transient voice change (5 cases; 4.76 %), skin pigmentation (1 case; 0.9 %), and fibrous band of wound (1 case; 0.9 %). The overall mean operative time was 105 min, and the mean operative time in the experienced phase was 95 min. CUSUM analysis showed a decreasing trend at the 35th patient, suggesting that more than 35 cases were needed for the surgeon to gain proficiency. In 76.19 % of the cases, patients showed extreme satisfaction with the cosmetic results. CONCLUSION: Our results showed reasonable surgical outcomes compared to previous studies on endoscopic thyroidectomy. The SIET procedure is safe and feasible for benign thyroid tumors and has an acceptable learning curve for surgeons who are proficient in conventional endoscopic thyroidectomy.

Transforming Head and Neck Surgeon Into Thyroid Expert: The 2016 Hayes Martin Lecture.

With the rapid rise in the incidence of thyroid cancer, the number of thyroidectomies has increased remarkably in the last 10 years. Thyroidectomy accounts for approximately 40% of the workload in head and neck fellowship. The decision making in thyroid surgery is quite complex, especially when patients present with recurrent or advanced thyroid cancer. The complications of thyroid surgery can be very serious in relation to quality of life. Some of these complications can be avoided with meticulous surgical technique. Thyroid surgery continues to span various specialties, and surgical volume continues to be an important parameter in outcomes. Technological advances have made a significant impact in thyroid surgery; however, these need to be carefully evaluated before their routine implementation and for extracervical approaches to thyroidectomy. The use of external radiation therapy and targeted therapies has expanded in recent years for patients with recurrent thyroid cancer. In a specialized and tertiary care center, the thyroid expert should be well-trained to make appropriate complex decisions. Thyroid experts should be part of the multidisciplinary team managing thyroid cancer from A to Z.
