RESUMO
Transoral endoscopic thyroidectomy with vestibular approach (TOETVA) is a feasible new surgical procedure that does not require visible incisions. We describe our experience with three-dimensional (3D) TOETVA. We recruited 98 patients who were willing to undergo 3D TOETVA. Inclusion criteria were: (a) patients with a neck ultrasound (US) with an estimated thyroid diameter of 10cm or less; (b) estimated US gland volume ≤45ml; (c) nodule size ≤50mm; (d) benign tumor, such as thyroid cyst, goiter with one nodule, or goiter with multiple nodules; (e) follicular neoplasia; and (f) papillary microcarcinoma without evidence of metastases. The procedure is performed using a three-port technique at the oral vestibule, a 10mm port for the 30° endoscope, and two additional 5mm ports for dissecting and coagulation instruments. The CO2 insufflation pressure is set at 6mmHg. An anterior cervical subplatysmal space is created from the oral vestibule to the sternal notch and laterally to the sternocleidomastoid muscle. Thyroidectomy is performed entirely 3D endoscopically with conventional endoscopic instruments and intraoperative neuromonitoring. There were 34% total thyroidectomies and 66% hemithyroidectomies. Ninety-eight 3D TOETVA procedures were successfully performed without any conversions. The mean operative time was 87.6 minutes (59-118 minutes) for lobectomy and 107.6 minutes (99-135 minutes) for bilateral surgery. We observed one case of transient postoperative hypocalcemia. Paralysis of the recurrent laryngeal nerve did not occur. The cosmetic outcome was excellent in all patients. This is the first case series of 3D TOETVA.
RESUMO
BACKGROUND: Radiofrequency ablation (RFA) has been recently adopted into the practice of thyroidology in the United States, although its use as an alternative to traditional thyroid surgery in Asia and Europe came near the turn of the 21st century. In the United States, only a few studies with small sample sizes have been published to date. We examined outcomes of benign thyroid nodules treated with RFA from 2 North American institutions. METHODS: We performed a prospective, multi-institutional cohort study of thyroid nodules treated with RFA between July 2019 and January 2022. Demographics, sonographic characteristics of thyroid nodules, thyroid function profiles, procedural details, complications, and nodule volume measurements at 1, 3, 6, and 12 months follow-up were evaluated. Adjusted multivariate logistic regression analysis was performed to identify sonographic features associated with treatment failure. RESULTS: A total of 233 nodules were included. The median and interquartile range of volume reduction rate (VRR) at 1, 3, 6, and 12 months were 54% [interquartile range (IQR): 36%-73%], 58% (IQR: 37%-80%), 73% (IQR: 51%-90%), and 76% (IQR: 52%-90%), respectively ( P <0.001). Four patients presented with toxic adenomas. All patients were confirmed euthyroid at 3-month postprocedure follow-up. Two patients developed temporary hoarseness of voice, but no hematoma or nodular rupture occurred postprocedure. Elastography was significantly associated with VRR. Compared with soft nodules, stiff nodules were more likely to have a lower VRR (odds ratio: 11.64, 95% confidence interval: 3.81-35.53, P <0.05), and mixed elasticity was also more likely to have a lower VRR (odds ratio: 4.9; 95% confidence interval: 1.62-14.85, P <0.05). CONCLUSIONS: This is the largest multi-institutional North American study examining thyroid nodule treatment response to RFA. RFA is a safe and effective treatment option that allows preservation of thyroid function with minimal risk of procedural complications.

Graves' disease (GD) can be managed by antithyroid drugs (ATD), radioactive iodine (RAI) and surgery. Thyroidectomy offers the highest success rates for both primary and persistent disease, yet it is the least recommended or utilized option reaching <1% for primary disease and <25% for persistent disease. Several surveys have found surgery to be the least recommended by endocrinologists worldwide. With the development of remote access thyroidectomies and intraoperative nerve monitoring of the recurrent laryngeal nerve, combined with current knowledge of possible risks associated with RAI or failure of ATDs, revaluation of the benefit to harm ratio of surgery in the treatment of GD is warranted. The aim of this review is to discuss possible reasons for the low proportion of surgery in the treatment of GD, emphasizing an evidence-based approach to the clinicians' preferences for surgical referrals, surgical indications and confronting traditional reasons and concerns relating to the low referral rate with up-to-date data.

IMPORTANCE: The transoral vestibular approach for thyroid and parathyroid surgery is being adopted rapidly world-wide. Currently there is a paucity of information on this approach for primary hyperparathyroidism (PHPTH). If this approach is safe and efficacious it would provide patients a completely scarless option for parathyroidectomy. OBJECTIVE: To determine whether parathyroidectomy via the transoral vestibular approach can be successfully done in a safe and efficient manner. DESIGN: Consecutive case series of 101 transoral parathyroidectomies performed over a two-year period. SETTING: Multi-institutional, academic, high-volume transoral thyroidectomy centers from the USA, Israel, and Thailand. PARTICIPANTS: A consecutive series of adult patients with a biochemical diagnosis of classic PHPTH and who met criteria for parathyroidectomy based on established international consensus for surgery for PHPTH. All patients also had well-localized single adenomas on at least two preoperative imaging studies. INTERVENTION: Transoral endoscopic parathyroidectomy vestibular approach. MAIN OUTCOMES AND MEASURES: Surgical success rate defined by immediate intra or post-operative return to normal PTH values. Surgical complications including recurrent laryngeal nerve injury, permanent hypoparathyroidism, and infection. RESULTS: Of the 101 consecutive transoral parathyroidectomy patients 84% were female with an average age of 54.23 ± 11.0 years and an average BMI of 27.35 ± 6.19. Ninety-nine out of the 101 patients had immediate return to normal PTH after resection for a surgical success rate of 98%. There were no permanent recurrent laryngeal nerve injuries, one temporary nerve palsy, and no permanent hypoparathyroidism. The median operative time dropped from 130.5 min (IQR 86) to 66.5 min (IQR 56) between the first- and second-half of cases. CONCLUSION AND RELEVANCE: Transoral endoscopic parathyroidectomy via the vestibular approach is a scarless method of removing parathyroids that is clinically feasible, safe, and efficacious and is a reasonable option for focused minimally invasive parathyroidectomy that can be offered to select patients with PHPTH.

INTRODUCTION: A cervical scar has been shown to have an impact on the quality of life of children undergoing thyroid surgery. Transoral endoscopic vestibular thyroidectomy via the vestibular approach (TOETVA) offers the absence of a cutaneous incision, and has not been described to date in the pediatric population. OBJECTIVE: To describe the first series of TOETVA in a pediatric population. PATIENTS AND METHODS: A retrospective, multicenter study, including all patients > 18 years old who underwent TOETVA. Data was prospectively collected and included demographics, preoperative ultrasound, cytology and indications for surgery. Intraoperative parameters included length of surgery and complications, with final pathology and postoperative course also reviewed. TOETVA surgical success was defined as completion of surgery via this approach. RESULTS: Forty-eight children were included. Of these, 43 (89.5%) were girls. The median age was 16 years (range 10-17). The most common indication for surgery was a benign thyroid nodule (n = 26, 54.1%). Eleven patients (22.9%) had papillary thyroid carcinoma on final pathology, of which 90.9% (10/11) were diagnosed pre-operatively based on FNA cytology. Hemithyroidectomy was performed in 36 patients (75%). All surgeries were completed endoscopically. The mean malignant tumor size was 1.4 ± 0.4 cm and all tumors were completely excised with clean margins. No permanent complications were documented. A single patient (2.1%) had transient RLN injury (1.6%, 1/60 nerves at risk). Transient hypocalcemia was documented in 4 of the 12 patients undergoing total thyroidectomy (33.3%). Transient mental nerve injury/chin hypoesthesia was documented in 2 patients (4.2%). CONCLUSIONS: TOETVA appears to be a feasible and safe approach for thyroidectomy in the pediatric population in carefully selected cases, and may be discussed with patients and parents as an alternative for the trans-cervical approach.

BACKGROUND: Various approaches for thyroid surgery became possible with the use of robotic systems. Transoral robotic thyroidectomy (TORT) is one of the newest approaches and draws attention because of its cosmetic excellence. In this study, we compared the surgical outcomes of TORT and conventional open thyroidectomy (OT). METHODS: We retrospectively reviewed and compared the medical records of consecutive patients who underwent TORT or OT for thyroid carcinoma from March 2009 to January 2018. Propensity score matching using 10 clinico-pathologic factors was used to generate two matched cohorts, each composed of 186 patients. RESULTS: The study included 372 patients who underwent TORT (n = 186) or OT (n = 186). Mean age, tumor size, and gender were not different between both groups. The two groups showed similar surgical outcomes, except for a longer operative time for TORT. There was one patient with immediate postoperative bleeding in the TORT group. The patient underwent re-operation for hemostasis with endoscopic approach. In the OT group, one patient had wound seroma, which was treated by several rounds of needle aspiration without infection. Vocal cord palsy was present in one patient in the TORT group, which was recovered in 3 months. CONCLUSIONS: TORT could be performed safely and had comparable surgical outcomes with OT in the selected patients. TORT may be a suitable operative alternative for patients who do not want to leave scars on the neck.

BACKGROUND: North American adoption of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) has been limited due to concerns regarding the generalizability of published outcomes, as data are predominantly from Asian cohorts with a different body habitus. We describe our experience with TOETVA in a North American population in the context of the conventional transcervical approach thyroidectomy (TCA). STUDY DESIGN: Cases of TOETVA and TCA were reviewed from August 2017 to March 2020 at a tertiary care center. Outcomes included operative time, major (permanent recurrent laryngeal nerve (RLN) injury, permanent hypoparathyroidism, hematoma, conversion to open surgery), and minor complications. The TOETVA cohort was stratified into body mass index (BMI) classes of underweight/normal < 25 kg/m2, overweight 25-29.9 kg/m2, and obese ≥ 30 kg/m2 for comparative analysis. Multivariable logistic regression analyses were performed for odds of cumulative complication. RESULTS: Two hundred TOETVA and 333 TCA cases were included. There was no difference in incidence of major complications between the TOETVA and TCA cohorts (1.5% vs. 2.1%, p = 0.75). No difference was found in the rate of temporary RLN injury (4.5% vs. 2.1%, p = 0.124) or temporary hypoparathyroidism (18.2% vs. 12.5%, p = 0.163) for TOETVA and TCA, respectively. Surgical technique (TOETVA vs TCA) did not alter the odds of cumulative complication (OR 0.69 95% CI [0.26-1.85]) on logistic regression analysis. In the TOETVA cohort, higher BMI did not lead to a significantly greater odds of cumulative complication, 0.52 (95% CI [0.17-1.58]) and 1.69 (95% CI [0.74-3.88]) for the overweight and obese groups, respectively. CONCLUSION: TOETVA can be performed in a North American patient population without a difference in odds of complication compared to TCA. Higher BMI is not associated with greater likelihood of complication with TOETVA.

OBJECTIVE: To evaluate the efficacy and safety of radiofrequency ablation (RFA) for the treatment of primary hyperparathyroidism (pHPT). METHODS: Our study enrolled 25 patients who were treated with RFA for pHPT from September 2015 to January 2020. The serum intact parathyroid hormone (iPTH), calcium, and phosphate levels were tested within 1 week before RFA and at 1 day, 1 month, 3 months, 6 months, and 12 months after ablation. The ablation areas were evaluated using ultrasound at 1, 3, 6, and 12 months after RFA. Postoperative complications, including voice hoarseness, hematoma, postoperative pain, incision infections, hypoparathyroidism, and hypocalcemia, were recorded. RESULTS: A total of 25 patients with pHPT (mean age, 53.9 ± 10.9 years; 22 women and 3 men) with 29 enlarged parathyroid glands were treated with RFA. Of the 25 patients, 22 were treated in 1 session and 3 were treated in 2 sessions. Serum iPTH and calcium levels decreased significantly on day 1 after RFA (all P < .05). A total of 21 patients had normal levels of serum iPTH and calcium after RFA, with a cure rate of 84%. At the 12-month follow-up, 26 treated parathyroid glands exhibited a volume reduction rate of >70%. There were only a few minor complications, including 4 cases of postoperative pain (in 4 of the 25 patients [16%]) and 1 case of mild postoperative transient hypocalcemia (in 1 of the 25 patients [4%]). CONCLUSION: Ultrasound-guided RFA is an effective and safe technique for the treatment of carefully selected patients with pHPT. However, larger sample size and longer follow-up are still needed to further confirm its clinical value.

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.

Over the past 20 years, various alternative cervical minimally invasive (partly endoscopically assisted) and extracervical endoscopic (partly robot-assisted) approaches have been developed. All of these alternative access methods aim at optimizing the cosmetic results. In principle, the indication for the use of alternative access procedures does not differ from that for conventional surgery. Nonetheless, appropriate experience in traditional thyroid surgery and suitable patient selection, taking into account thyroid volumes and the underlying pathology, are important prerequisites. General contraindications for an alternative approach are large goiter with symptoms of compression, advanced thyroid carcinoma, recurrent interventions or previous radiotherapy in the operating area. The alternative surgical approaches to the thyroid can be divided into cervical minimally invasive, extracervical endoscopic (robot-assisted) and transoral procedures. This article gives an overview of the clinically used alternative approaches in thyroid surgery. The desire for an optimal cosmetic result should not be prioritized over patient safety. Only a few alternative procedures (minimally invasive video-assisted thyroidectomy, transaxillary robot-assisted thyroidectomy) can currently be viewed as a useful addition to conventional thyroid surgery, even when in responsible, experienced hands for a selected group of patients.

Background. The hybrid ultrasonic advanced bipolar device (HUB) that integrates ultrasonic energy and advanced bipolar energy was recently developed and applied to thyroid surgery. The purpose of this study was to compare the efficacy and safety of HUB and ultrasonic coagulating shears for open thyroidectomy. Methods. A total of 200 patients were enrolled from April to September 2017 in this prospective, randomized, multicenter study. Patients were randomly assigned to an ultrasonic group (n = 101) or a hybrid group (n = 99). Results. Operation times were similar in the 2 study groups, that is, 54.2 ± 25.2 minutes in the ultrasonic group and 50.2 ± 21.6 minutes in the hybrid group. Postoperative surgical results and morbidities were no different in the 2 groups. However, the total amount of bleeding was significantly less in the hybrid group (13.0 ± 17.7 mg vs 8.6 ± 11.5 mg; P = .042). Conclusions. Our study showed that there was no significant difference between the 2 groups in postoperative surgical results and morbidity. The total bleeding amount was significantly less in the hybrid group. The study shows that HUB is comparable to the ultrasonic coagulating shears in terms of efficacy and safety during thyroid surgery.

BACKGROUND: Transoral robotic thyroidectomy (TORT) for differentiated thyroid carcinoma is increasing in popularity. However, studies are limited to small tumors. This study aimed to compare the outcomes of TORT for papillary thyroid carcinomas smaller than 1 cm and 1 cm or larger. METHODS: The study analyzed 269 patients with papillary thyroid carcinoma who underwent TORT at Korea University Hospital, Korea between January 2001 and December 2017. Surgical outcomes and postoperative complications were compared. RESULTS: Group 1 (tumor < 1 cm) had 215 patients, and group 2 (tumor ≥ 1 cm) had 54 patients. The majority of the patients underwent lobectomy (95.8% in group 1 and 87.0% in group 2; p = 0.339) and unilateral central neck dissection (96.3% in group 1 and 88.9% in group 2; p = 0.024). The two groups did not differ significantly in terms of gender, age, body mass index, thyroiditis status, Da Vinci model. or operative procedure. The majority of the tumors in group 1 (73%) had T1a staging, whereas the majority of the tumors in group 2 were stage T1b or T3a (44.4% in each group; p = 0.000). Most of the patients in group 1 had N0 staging (59.1%), whereas most of the patients in group 2 had N1a staging (55.6%; p = 0.026). The mean operative time was significantly longer in group 2 (198.0 ± 34.2 min in group 1 vs. 215.7 ± 49.3 min in group 2; p = 0.015). The two groups did not differ significantly regarding length of stay, postoperative pain score, or thyroglobulin level. No patients experienced locoregional or distant recurrence. No statistically significant difference in overall complications was observed (p = 0.214). CONCLUSIONS: Transoral robotic thyroidectomy is a safe and effective procedure and may be a feasible option for patients with papillary thyroid carcinomas larger than 1 cm.

BACKGROUND: Endoscopic transoral thyroidectomy is a recently introduced technique of remote access thyroidectomy. We previously reported the feasibility of the robotic approach (TORT). Nevertheless, experience to date is limited, with scant data on outcomes in patients with papillary thyroid carcinoma (PTC). METHODS: This was a retrospective analysis of prospectively collected data. Patients with PTC, who underwent TORT at a single center between March 2016 and February 2017, were analyzed. RESULTS: There were a total of 100 patients (85 women, 15 men) with a mean age of 40.7 ± 9.8 years, and a mean tumor size of 0.8 ± 0.5 cm. Nine patients underwent a total thyroidectomy, and 91 underwent a lobectomy. The operative time for a total thyroidectomy and lobectomy was 270.0 ± 9.3 and 210.8 ± 32.9 min, respectively. Ipsilateral prophylactic central neck compartment dissection was performed routinely with retrieval of 5.0 ± 3.6 lymph nodes. Perioperative morbidity was present in nine patients including transient recurrent laryngeal nerve palsy (n = 1), postoperative bleeding requiring surgical intervention (n = 1), zygomatic bruising (n = 2), chin flap perforation (n = 1), oral commissure tearing (n = 2), and chin dimpling (n = 2). There was no conversion to endoscopic or conventional open thyroid surgery. CONCLUSION: In this study, TORT could be safely performed in a large series of patients with PTC without serious complications. In selected patients, TORT by experienced surgeons could be considered an alternative approach for remote access thyroidectomy.

OBJECTIVES: Transoral robotic thyroidectomy (TORT) is a new remote access approach to avoid cervical incision. The purpose of this study is to compare two approaches used to avoid cervical incision: transoral approach and bilateral axillo-breast approach (BABA) in robotic thyroidectomy. METHODS: A total of 90 patients were enrolled prospectively between September 2016 and April 2017. The BABA group had 43 and the TORT group had 47 patients, respectively. Parameters including clinicopathologic data, operative time, complications, laboratory data, hospital stay, postoperative pain, and cosmetic satisfaction were analyzed. RESULTS: Complications were not different among the two groups. The operative time of TORT was longer than BABA until 15 cases of TORT were completed, but there was no difference after that. The Visual Analogue Scale score in TORT was lower than BABA in all the periods. TORT showed a higher cosmetic satisfaction after surgery. There was no infection or permanent mental nerve hypoesthesia in TORT. CONCLUSION: Our study showed that TORT had less postoperative pain and a greater cosmetic satisfaction than the BABA. There were no significant differences in the postoperative surgical results between the two groups. TORT was comparable to the BABA in outcome with higher cosmetic satisfaction and less pain.

BACKGROUND: Intraoperative PTH (IOPTH) monitoring has been widely used to confirm the removal of the culprit lesion during operation. However, the true benefit of IOPTH in patients with preoperatively well-localized single adenoma has been questioned. The aim of this study was to examine how or if IOPTH changes the surgical management and outcomes in patients with only one positive or only indeterminate localization studies. METHODS: This is a retrospective review of data from a parathyroid surgery database and patient records from July 2004 to June 2014, including patients with primary hyperparathyroidism with a planned MIP by two experienced endocrine surgeons after ≥1 positive/indeterminate preoperative localization study by ultrasound and/or sestamibi. RESULTS: A total of 482 patients with positive (342: 259 only 1, 83 with ≥2) or indeterminate (140: 105 only 1, 35 with ≥2) preoperative imaging studies were included. IOPTH changed the management in only 16 (3%) patients, with an additional lesion found in 12 of them. Surgical cure was achieved in 471 (98%) of patients (98% in the positive vs. 97% in the indeterminate group, p 0.58). With or without IOPTH, the cure rate would not have been significantly different in patients with only 1 positive preoperative imaging (96 vs. 98%, p 0.12). Similar results were seen in those with ≥2 indeterminate (100% cure rate with or without IOPTH). CONCLUSION: Our study suggests that MIP may be safely and successfully performed without IOPTH for patients with ≥1 positive or ≥2 indeterminate preoperative imaging studies. This study is retrospective within inherent biases, and future prospective study is warranted.

PURPOSE: During monitored thyroidectomy, a partially or completely disrupted point of nerve conduction on the exposed recurrent laryngeal nerve (RLN) indicates true electrophysiologic nerve injury. Complete loss of signal (LOS; absolute threshold value <100 µV) at the end of operation often indicates a postoperative vocal cord (VC) palsy. However, the evaluation for the injured RLN with incomplete LOS and its functional outcome has not been well described. METHODS: Three hundred twenty-three patients with 522 RLNs at risk who underwent standardized monitored thyroidectomy were enrolled. The RLN was routinely stimulated at the most proximal (R2p signal) and distal (R2d signal) ends of exposure after thyroid resection to determine if there was an injured point on the RLN. Pre- and postoperative VC function was routinely examined. RESULTS: Twenty-nine RLNs (5.6 %) were detected with an injury point. Five nerves had complete LOS and other 24 nerves had incomplete LOS where the R2p/R2d reduction (% of amplitude reduction compared with proximal to distal RLN stimulation) ranged from 22 to 79 %. Postoperative temporary VC palsy was noted in those five RLNs with complete LOS (final vagal signal, V2 < 100 µV) and four RLNs with incomplete LOS (R2p/R2d reduction 62-79 %; V2 181-490 µV). In the remaining 20 nerves with R2p/R2d reduction ≤53 % (V2 373-1623 µV), all showed normal VC mobility. Overall, false negative results were found in two RLNs (0.4 %) featuring unchanged V2 and R2p/R2d but developed VC palsy. CONCLUSIONS: Testing and comparing the R2p/R2d signal is a simple and useful procedure to evaluate RLN injury after its dissection and predict functional outcome. When the relative threshold value R2p/R2d reduction reaches over 60 %, surgeon should consider the possibility of postoperative VC palsy.

We depict the transoral endoscopic thyroidectomy vestibular approach (TOETVA). Patient selection criteria are (1) ultrasonographically (US) estimated thyroid diameter no larger than 10cm, (2) US estimated gland volume ≥45mL, (3) nodule size ≥5mm, (4) a benign tumor, such as a thyroid cyst, single-nodular goiter, or multinodular goiter, (5) follicular neoplasm, and (6) papillary microcarcinoma without evidence of metastasis. TOETVA is carried out through a three-port technique placed at the oral vestibule, one 10mm port for 30° endoscope and two additional 5mm ports for dissecting and coagulating instruments. CO2 insufflation pressure is set at 6mmHg. An anterior cervical subplatysmal space is created from the oral vestibule down to the sternal notch, laterally to the sternocleidomastoid muscles bilaterally. Thyroidectomy is done fully endoscopically using conventional endoscopic instruments. Intraoperative neuromonitoring is used for identification and dissecting and monitoring both the superior and inferior laryngeal nerves.

BACKGROUND: We sought to seek the potential role of endoscopic thyroidectomy with the retroauricular (RA) approach prior to future comparative study with the robotic RA thyroidectomy. Therefore, this study aims to verify the surgical feasibility of endoscopic RA thyroidectomy. METHODS: Eighteen patients who underwent endoscopic RA thyroidectomy for clinically suspicious papillary thyroid carcinoma or benign lesions from January to December 2013 were retrospectively reviewed and analyzed. RESULTS: All endoscopic operations via RA or modified facelift approach were successfully performed, without any significant intraoperative complications or conversion to open surgery. Based on patient-reported outcome questionnaires, all patients were satisfied with their postoperative surgical scars. CONCLUSION: Endoscopic RA thyroidectomy is technically feasible and safe with satisfactory cosmetic results for patients where indicated.
