The treatment of hyperparathyroidism through parathyroidectomy requires careful and complete preoperative evaluation. There are multiple imaging modalities and methods available to clinicians today to aid in identifying a pathological lesion; however, each has limitations that the clinician must understand. A systematic approach to patient evaluation, imaging, and surgical exploration is necessary to ensure accurate diagnosis and maximize the chances of minimally invasive and successful surgical removal., (Copyright © 2023 Elsevier Inc.

Background: Radiofrequency ablation for benign thyroid nodules aims to achieve a volume reduction rate of ≥50%. However, factors that predict treatment success have not been defined in a large-scale study., Methods: A prospective cohort study of biopsy-proven benign thyroid nodules treated with radiofrequency ablation at 3 institutions was performed. Patient demographics, nodule sonographic features, procedural data, and nodule volume reduction were evaluated. Binary logistic regression analysis was performed to identify features associated with treatment response., Results: A total of 620 nodules were analyzed. The pooled median volume reduction rate at 12 months was 70.9% (interquartile range 52.9-86.6). At 1 year follow-up, 78.4% of nodules reached treatment success with a volume reduction rate ≥50%. The overall complication rate was 3.2% and included temporary voice changes (n = 14), vasovagal episodes (n = 5), nodule rupture (n = 3), and lightheadedness (n = 2). No permanent voice changes occurred. Four patients developed postprocedural hypothyroidism. Large baseline nodule volume (>20 mL) was associated with a lower rate of successful volume reduction (odds ratio 0.60 [0.37-0.976]). Large nodules achieved treatment success by 12-month follow-up at a rate of 64.5%, compared with 81.4% for small nodules and 87.2% for medium nodules., Conclusion: To our knowledge, this is the largest North American cohort of patients with benign thyroid nodules treated with radiofrequency ablation. Overall, radiofrequency ablation was an effective treatment option with a low risk of procedural complications. Large volume nodules (>20 mL) may be associated with a lower rate of successful reduction with radiofrequency ablation treatment., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Objective: The value-based healthcare model aims to improve the quality of care and lower health care costs. The standard value equation (ie, Value = Quality/Cost), while conceptually useful, is grossly oversimplified and lacks clinical relevance. This study introduces a more detailed value equation that generates disease-specific value scores and incorporates real-world clinical and cost data to demonstrate its use., Study Design: Prospective observational study., Setting: Tertiary institution., Methods: A comprehensive new health care value equation was developed that includes 23 unique inputs. Sixteen inputs represent quality (numerator) and 7 inputs represent cost (denominator). Patients undergoing thyroid or parathyroid surgery were enrolled, and data were entered into the new equation to generate surgery-specific value scores for each patient. A subanalysis was performed for telehealth visits., Results: Ten patients were enrolled (60% female) with an average age of 62 years. The average total monetary cost per patient was $41,884 ($27,885 direct). Across all patients, the average total quality score was 0.99, and the cost score was 6.1, resulting in a final value score of 0.19. A subanalysis showed that changing a postoperative visit from in-person to telehealth would increase the value score by 0.66%., Conclusion: This analysis creates a comprehensive value equation for surgical services that incorporates the complexity of modern surgical care. The new equation includes objective and subjective outcomes and health equity, quantitatively compares the value of different surgical interventions and health care services, illustrates how specific interventions can lead to the higher value of care, and can serve as the framework for future value equations., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Objective: Radiofrequency ablation (RFA) of benign thyroid nodules has gained traction for its therapeutic effectiveness, thyroid function preservation, and minimally invasive nature. While a growing body of evidence reports positive outcomes from thyroid RFA, financial comparisons between both procedures remain limited. This analysis aims to more accurately measure the direct cost of thyroid RFA in comparison to thyroid lobectomy., Study Design: Bottom-up financial cost analysis., Setting: Tertiary endocrine head and neck surgery center., Methods: Time-driven activity-based costing was utilized to obtain unit-based cost estimates. The care cycles for thyroid lobectomy and RFA were defined, and process maps were developed comprising all personnel and work in the care cycle. Time estimates were calculated for all personnel involved, and public government data were used to obtain capacity cost rates for each component of the care cycle. Consumable supply and overhead costs were obtained for both procedures, and overall costs were compared., Results: For thyroid lobectomy, total personnel costs were $1087.97, consumable supplies were $942.68, and overhead costs $17,199.10. For thyroid nodule RFA performed in an office setting, the total personnel cost calculated was $379.90, consumable supplies $1315.28, and overhead $7031.20. Overall, the total cost for thyroid lobectomy was $19,229.75 compared to $8726.38 for RFA., Conclusion: In-office thyroid nodule RFA is associated with lower direct costs than thyroid lobectomy, and overhead is the greatest cost driver for both procedures. If clinical and patient-centered outcomes are comparable, then RFA may provide higher value for appropriately selected patients., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Before the 20th century, thyroid surgery was regarded as "horrid butchery" such that no honest and sensible surgeon would ever engage in it. Yet, by the mid-20th century, thyroidectomy had become a respected, life-saving, safe, and increasingly practiced operation. From Kocher to Wells and onward into the 21st century, the evolution of thyroid surgery has continued, enhanced by the integration of endocrinology, genetics, immunology, physiology, technology, training, and multidisciplinary care. The ability to personalize and optimize the care of thyroid disorders has been progressively achieved through shared insights and discoveries, highlights of which are described herein.

Devices for near-infrared light stimulation of autofluorescence (NIRAF) allow for intraoperative identification of parathyroid glands with high sensitivity in adults. However, their performance in the pediatric population is unknown. In this case series with chart review at a tertiary academic children's hospital, we investigated pediatric patients undergoing thyroid surgery and concurrent use of a probe-based NIRAF device. Thirteen patients (ages 6-18 years) underwent thyroid and/or neck dissection procedures, and 2 patients had revision procedures for a total of 15 cases with the NIRAF device. Eight cases had NIRAF values that matched surgeon opinion of parathyroid tissue or histology when available. Six cases had false positive NIRAF readings (40.0%) and 1 case had false negative readings (6.7%). Compared with surgeon opinion or histology, the NIRAF device confirmed 26 of 34 parathyroid gland candidates (76.5%). These devices need further investigation in pediatric patients, whose tissues may have different autofluorescence characteristics., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

Background: Diagnosis of papillary thyroid microcarcinoma, defined as papillary thyroid carcinoma measuring 1cm or less in greatest diameter, has increased with improvements in ultrasound technology and widespread familiarity and utilization. Given the indolent course of papillary thyroid carcinoma, active surveillance is considered an acceptable alternative to surgical resection for select patients. Candidacy for active surveillance is determined by a number of patient and tumor characteristics. Specifically, the location of the tumor within the thyroid gland plays one of the key roles in decision making. Here we evaluate characteristics of the primary tumor and distance to the thyroid capsule in association with locoregional metastases to help guide risk assessment., Methods: Retrospective chart review of all thyroid surgeries performed by two surgeons at one medical center from 2014-2021 to evaluate characteristics of papillary thyroid microcarcinoma on preoperative ultrasound that are associated with locoregional metastatic disease., Results: Our data show a sensitivity of 65% and specificity of 95% for identifying regional metastases in papillary thyroid microcarcinoma using preoperative ultrasound. We found no correlation between regional metastasis and size of tumor, distance to thyroid capsule or trachea, tumor contour, or presence of autoimmune thyroiditis. Nodules in the superior or midpole were associated with central or lateral neck metastases, whereas nodules in the isthmus or inferior pole were only associated with central neck metastases., Conclusions: Active surveillance may be a reasonable option for even those papillary thyroid microcarcinomas adjacent to the thyroid capsule., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Cohen, Noel, Baroody and Orloff.)

Importance: Thyroid cancer is the most common pediatric endocrine malignant neoplasm. Disparities in the workup of thyroid nodules may be significantly associated with thyroid cancer outcomes., Objective: To determine the association of sociodemographic factors with the odds of receiving a biopsy, timeliness of the procedure, and risk of nodule malignancy., Design, Setting, and Participants: This was a retrospective cross-sectional study using insurance claims data from the Optum Clinformatics Data Mart database. The study cohort comprised pediatric patients diagnosed with single thyroid nodules between 2003 and 2020. Data analysis was performed from January 1, 2003, to June 30, 2020., Main Outcomes and Measures: Multivariable logistic regression models were used to identify demographic variables associated with biopsy and nodule malignant neoplasm. A multivariable linear regression model was used to assess the time between thyroid nodule diagnosis and biopsy., Results: Of 11 643 children (median [IQR] age at diagnosis or procedure, 15 [12-17] years; 8549 [73.2%] were female and 3126 [26.8%] were male) diagnosed with single thyroid nodules, 2117 (18.2%) received a biopsy. Among the patients who received a biopsy, 304 (14.4%) were found to have a malignant nodule. Greater parental education was associated with a shorter diagnosis-to-biopsy interval (mean difference, -7.24 days; 95% CI, -13.75 to -0.73). Older age at nodule diagnosis (odds ratio [OR], 1.11; 95% CI, 1.09-1.13) and female gender (OR, 1.25; 95% CI, 1.11-1.40) were associated with increased odds of receiving a biopsy, while Black/African American (OR, 0.80; 95% CI, 0.65-0.99) and Hispanic (OR, 0.84; 95% CI, 0.72-0.99) patients had lower odds of receiving a biopsy compared with White patients. Finally, female gender (OR, 1.08; 95% CI, 0.80-1.47) was not associated with lower odds of nodule malignant neoplasm., Conclusions and Relevance: Findings of this cross-sectional study highlight disparities in the diagnostic management of pediatric thyroid nodules. These results call for future work to ensure equitable access to thyroid care for all children.

Background: Ultrasonography has become an essential tool for the evaluation and management of thyroid and parathyroid diseases. Its applications extend beyond neck endocrine conditions to a multitude of pathologies within the head and neck region., Objectives: Our study aimed to: (1) provide a broad review of neck ultrasonography and key findings in neck endocrine diseases; (2) support skilled performance office-based diagnostic ultrasonography and its varied applications., Materials and Methods: A review of the current literature was supplemented with clinical examples of key ultrasonographic findings., Results: Current applications and key findings of ultrasonography in the diagnosis and management of neck endocrine conditions are reviewed., Conclusion: Ultrasonography is a fundamental component in the evaluation and management of neck endocrine diseases. The reader is encouraged to use this review to enhance office-based performance and application of ultrasonography., (© 2022.

Objective: To evaluate the significance of antithyroglobulin and antithyroid peroxidase antibody levels associated with locoregional metastatic disease in patients with well-differentiated thyroid cancer., Methods: Patients underwent initial treatment for well-differentiated thyroid cancer at our institution between 2014 and 2018. The following variables were collected: age, sex, pre-operative thyroid-stimulating hormone, thyroglobulin, antithyroglobulin antibody (TgAb), antithyroid peroxidase antibody (TPOAb), the extent of surgery, T-stage, N-stage, extrathyroidal extension (ETE), extranodal extension (ENE), lymphovascular invasion, and multifocal disease. The relationships between disease status and pre-operative TPOAb, TgAb, thyroglobulin, and thyroid-stimulating hormone were analyzed., Results: A total of 405 patients (mean age, 52 years) were included in the study, of which 66.4% were women. Elevated TgAb was associated with the presence of lymph node metastases (LNM) in both the central and lateral neck (P < .01), with a stronger correlation to N1b versus N1a disease (P = .03). The presence of ETE was inversely related to the TgAb titer (P = .03). TPOAb was associated with a lower T-stage (P = .04), fewer LNM (P = .04), and a lower likelihood of ETE (P = .02). From multivariable analysis, TgAb ≥40 IU/mL was an independent predictive factor for a higher N-stage (P < .01 for N0 vs N1; P = .01 for N1a vs N1b), and ENE (P < .01). TPOAb ≥60 IU/mL was associated with a lower T-stage (P = .04 for T <3) and absence of ETE (P = .01)., Conclusion: Elevated pre-operative TgAb was an independent predictor of nodal metastases and ENE, while elevated TPOAb was associated with a lower pathologic T- and N-stage. Pre-operative antithyroid antibody titers may be useful to inform the disease extent and features., (Copyright © 2021 AACE. Published by Elsevier Inc. All rights reserved.)

Ultrasound has become indispensable for identification of thyroid and parathyroid pathology, but normal parathyroid glands have historically been considered too subtle to accurately detect. Inability to identify and protect parathyroid glands can result in hypoparathyroidism and hypocalcemia during thyroidectomy surgery as well as misinterpretation of central neck structures in the postoperative neck. Advances in ultrasound resolution have opened the door to novel applications for this technology. In this study, we report the first surgeon-performed ultrasound identification of normal parathyroid glands in a series of 6 patients, confirmed by parathyroid tissue aspirate or parathyroid autofluorescence. Recognition of normal parathyroid glands using ultrasound can be valuable for preventing postoperative hypoparathyroidism and in increasing the accuracy of postsurgical ultrasound surveillance., (© The Authors 2021.)

Background: This American Head and Neck Society (AHNS) consensus statement focuses on evidence-based comprehensive pain management practices for thyroid and parathyroid surgery. Overutilization of opioids for postoperative pain management is a major contributing factor to the opioid addiction epidemic however evidence-based guidelines for pain management after routine head and neck endocrine procedures are lacking., Methods: An expert panel was convened from the membership of the AHNS, its Endocrine Surgical Section, and ThyCa. An extensive literature review was performed, and recommendations addressing several pain management subtopics were constructed based on best available evidence. A modified Delphi survey was then utilized to evaluate group consensus of these statements., Conclusions: This expert consensus provides evidence-based recommendations for effective postoperative pain management following head and neck endocrine procedures with a focus on limiting unnecessary use of opioid analgesics., (© 2021 Wiley Periodicals LLC.)

Surgeons must visually distinguish soft-tissues, such as nerves, from surrounding anatomy to prevent complications and optimize patient outcomes. An accurate nerve segmentation and analysis tool could provide useful insight for surgical decision-making. Here, we present an end-to-end, automatic deep learning computer vision algorithm to segment and measure nerves. Unlike traditional medical imaging, our unconstrained setup with accessible handheld digital cameras, along with the unstructured open surgery scene, makes this task uniquely challenging. We investigate one common procedure, thyroidectomy, during which surgeons must avoid damaging the recurrent laryngeal nerve (RLN), which is responsible for human speech. We evaluate our segmentation algorithm on a diverse dataset across varied and challenging settings of operating room image capture, and show strong segmentation performance in the optimal image capture condition. This work lays the foundation for future research in real-time tissue discrimination and integration of accessible, intelligent tools into open surgery to provide actionable insights., (© 2021.

Importance: The rapidly expanding novel coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2, has challenged the medical community to an unprecedented degree. Physicians and health care workers are at added risk of exposure and infection during the course of patient care. Because of the rapid spread of this disease through respiratory droplets, health care workers who come in close contact with the upper aerodigestive tract during diagnostic and therapeutic procedures, such as otolaryngologists-head and neck surgeons, are particularly at risk. A set of safety recommendations was created based on a review of the literature and communications with physicians with firsthand knowledge of safety procedures during the COVID-19 pandemic., Observations: A high number of health care workers were infected during the first phase of the pandemic in the city of Wuhan, China. Subsequently, by adopting strict safety precautions, other regions were able to achieve high levels of safety for health care workers without jeopardizing the care of patients. The most common procedures related to the examination and treatment of upper aerodigestive tract diseases were reviewed. Each category was reviewed based on the potential risk imposed to health care workers. Specific recommendations were made based on the literature, when available, or consensus best practices. Specific safety recommendations were made for performing tracheostomy in patients with COVID-19., Conclusions and Relevance: Preserving a highly skilled health care workforce is a top priority for any community and health care system. Based on the experience of health care systems in Asia and Europe, by following strict safety guidelines, the risk of exposure and infection of health care workers could be greatly reduced while providing high levels of care. The provided recommendations, which may evolve over time, could be used as broad guidance for all health care workers who are involved in the care of patients with COVID-19.

We present Omni-ATAC, an improved ATAC-seq protocol for chromatin accessibility profiling that works across multiple applications with substantial improvement of signal-to-background ratio and information content. The Omni-ATAC protocol generates chromatin accessibility profiles from archival frozen tissue samples and 50-μm sections, revealing the activities of disease-associated DNA elements in distinct human brain structures. The Omni-ATAC protocol enables the interrogation of personal regulomes in tissue context and translational studies.

Objective: The dramatic increase in papillary thyroid carcinoma (PTC) is primarily a result of early diagnosis of small cancers. Active surveillance is a promising management strategy for papillary thyroid microcarcinomas (PTMCs). However, as this management strategy gains traction in the U.S., it is imperative that patients and clinicians be properly educated, patients be followed for life, and appropriate tools be identified to implement the strategy., Methods: We review previous active surveillance studies and the parameters used to identify patients who are good candidates for active surveillance. We also review some of the challenges to implementing active surveillance protocols in the U.S. and discuss how these might be addressed., Results: Trials of active surveillance support nonsurgical management as a viable and safe management strategy. However, numerous challenges exist, including the need for adherence to protocols, education of patients and physicians, and awareness of the impact of this strategy on patient psychology and quality of life. The Thyroid Cancer Care Collaborative (TCCC) is a portable record keeping system that can manage a mobile patient population undergoing active surveillance., Conclusion: With proper patient selection, organization, and patient support, active surveillance has the potential to be a long-term management strategy for select patients with PTMC. In order to address the challenges and opportunities for this approach to be successfully implemented in the U.S., it will be necessary to consider psychological and quality of life, cultural differences, and the patient's clinical status.

Importance: Papillary thyroid carcinoma (PTC) is the most common endocrine neoplasm. B-type raf kinase (BRAF) V600E mutation has been proposed as a negative prognostic indicator in PTC, and patients harboring it should receive more aggressive initial therapy., Objective: To assess the significance of BRAF V600E mutation in PTC in the largest US sample to date., Design: We identified patients from our institution's pathology archives diagnosed as having PTC and meeting criteria for BRAF mutation testing. Medical records were analyzed for BRAF status (positive or negative) and a list of standardized clinicopathologic features., Participants: A total of 429 patients with PTC at an academic medical center., Main Outcomes and Measures: Clinicopathologic features in patients with PTC with and without BRAF mutation., Results: Of 429 cases with PTC, 314 (73.2%) were positive for the BRAF mutation and 115 (26.8%) tested negative. BRAF mutation was significantly associated with tumor margin positivity (P = .03) and lymph node metastasis (P = .002) on univariate analysis but not on multivariate study. BRAF mutation was a predictor of male sex (odds ratio [OR], 3.2; 95% CI, 1.4-7.2), total thyroidectomy (OR, 2.6; 95% CI, 1.1-6.2), and a negative predictor of follicular variant PTC (OR, 0.1; 95% CI, 0.1-0.4). There was no significant association between BRAF positivity and tumor multicentricity, lymphovascular invasion, extranodal extension, central neck involvement, advanced stage (stage III or IV), and distant metastasis., Conclusions and Relevance: BRAF V600E mutation has been extensively studied in relation to negative prognostic indicators in PTC, with no consistent relationship emerging. Two recent meta-analyses showed an overall association between BRAF status and aggressive disease features and called for tailoring treatment plans in patients accordingly. In this, the largest US study to date, BRAF status was not significantly associated with most clinicopathologic features suggestive of more aggressive disease.

Objective: To describe our experience with therapeutic sialendoscopy for radioiodine (iodine 131 [(131)I]) sialadenitis., Design: Retrospective medical chart review., Setting: Academic tertiary referral center., Patients: The study included 11 patients who underwent therapeutic sialendoscopy for the treatment of (131)I sialadenitis after failing medical management., Interventions: Therapeutic sialendoscopy with dilation and irrigation of the ductal system was performed in all patients., Main Outcome Measures: Patient-reported frequency and severity of symptoms., Results: Our series included 9 women and 2 men (mean age, 51 years; age range, 35-65 years). A total of 23 parotid glands and 5 submandibular glands were treated. Sialendoscopy was possible in all patients, except one in whom the Stensen duct could not be cannulated. Typical endoscopic findings included pale ductal mucosa, thick mucous plugs, ductal debris, and stenosis of the duct. Most patients (91%) reported improvement of symptoms after a single procedure. Complete resolution of symptoms, with sustained benefit, was reported by 6 patients (54%) at a mean follow-up of 18 months. Partial improvement of symptoms, with some persistent intermittent episodes of pain or swelling, was reported by 4 patients (36%). One patient reported no subjective symptomatic improvement after 2 procedures and subsequently underwent a parotidectomy., Conclusions: Sialendoscopy is useful for the improvement of symptoms due to radioiodine-induced sialadenitis in patients who are refractory to conservative medical therapy. Therapeutic sialendoscopy appears to provide effective and sustained symptom improvement in most patients in our experience.

Thyroid ultrasonography has established itself as a popular and useful tool in the evaluation and management of thyroid disorders, both malignant and benign. Although its use has traditionally been the domain of radiologists, surgeons and endocrinologists are increasingly integrating this technology into their daily clinical and operative practice. This article provides an overview of the relevant uses and indications for ultrasound in various thyroid diseases, describes characteristic ultrasound findings in these diseases, and reviews the relevant literature and guidelines concerning its uses., (Copyright © 2010 Elsevier Inc.

Purpose: The purpose of this study is to describe the use of a full-thickness skin graft from the groin for coverage of the radial forearm free flap donor site. Our hypothesis is that the use of the full-thickness skin graft decreases morbidity and improves functional and cosmetic outcome at the skin graft donor site while also providing excellent coverage of the forearm donor site., Study Design: This study used a retrospective chart review design., Materials and Methods: Patients undergoing radial forearm free flap reconstructions from 1995 to 2005 were included. Forty patients underwent radial forearm free flap reconstruction with closure of the forearm donor site with a full-thickness skin graft harvested from the groin. The inguinal donor site was closed primarily. Medical records including clinic notes, operative reports, and photographs were reviewed., Results: There was 1 minor wound dehiscence at the groin site, and there were 5 minor forearm wound dehiscences with 2 cases of tendon exposure; all dehiscences were treated conservatively with local wound care. Both the groin wound and forearm donor sites healed satisfactorily in all cases, with no impairment of function related to the skin graft. All patients expressed satisfaction with the postoperative pain, functional outcome, and cosmetic appearance related to both the skin graft and forearm donor sites., Conclusions: Full-thickness skin graft from the groin for coverage of the radial forearm free flap donor site is an effective, safe alternative to the traditional split thickness skin graft.
