Guideline From the Brazilian Society of Surgical Oncology and Brazilian College of Surgeons in Preventing and Managing Acute Hypoparathyroidism After Thyroid Surgery.

The risk of hypoparathyroidism and hypocalcemia is a critical concern in thyroid surgery. Preserving parathyroid gland vascularization during surgery is essential for effective prevention. Preoperative and postoperative management, including calcium and Vitamin D supplementation, is paramount. Measurement of parathyroid hormone levels after surgery is the best predictor of hypoparathyroidism. This guideline offers recommendations for the prevention, diagnosis, and treatment of acute hypoparathyroidism and hypocalcemia after thyroid surgery.

Intraoperative indocyanine green angiography in preventing hypoparathyroidism after thyroid cancer surgery.

BACKGROUND: The aim of this study was to determine whether the use of indocyanine green angiography to identify devascularized parathyroids during thyroidectomy for thyroid cancer would decrease the rates of postoperative hypoparathyroidism. METHODS: Retrospective study of patients who had undergone total thyroidectomy for treatment of thyroid cancer between March 2021 and March 2023. The indocyanine group included patients with all four parathyroids identified and evaluated by indocyanine green angiography at the end of the procedure. Those with parathyroid glands classified with no vascularization had the glands autotransplanted. A group without indocyanine angiography was used to compare results. RESULTS: The analysis included 100 patients in each group. Indocyanine angiography identified 14.75% of devascularized parathyroids at surgery. The number of parathyroids with a score of 2 (i.e., good vascularization) was not a safe predictor of normal parathyroid hormone levels after surgery. Indeed, 29.2% of the patients with three parathyroids with a score of 2 developed transient hypoparathyroidism. Permanent hypoparathyroidism occurred in 7% of the patients without indocyanine group and in none of the patients in the indocyanine group (p = 0.014). CONCLUSION: Intraoperative angiography with indocyanine green could contribute to reduce the occurrence of permanent hypoparathyroidism in patients undergoing surgical treatment for thyroid cancer.

[Thyroid surgery in a context of scarce resources at Saint Martin de Porres Dominican Hospital (Yaounde, Cameroon)]. / Chirurgie thyroïdienne dans le contexte de populations avec de faibles ressources à l'hôpital dominicain Saint Martin de Porres (Yaoundé, Cameroun).

Introduction: Surgical campaigns for thyroid surgery in low-income environments are very efficient, but there is little literature reporting results. These campaigns are complex due to multiple particularities: highly evolved cases, the need for professionals to travel or an obvious socio-cultural barrier influence towards the surgical act. We describe a surgical campaign in Cameroon to treat patients with goiter and issue some medical and sociocultural recommendations in view of our experience for its implementation with guarantees. Material and methods: An experienced group carried out an 11-day campaign at the Saint Martin de Porres Dominican Hospital, Yaounde, Cameroon. Demographic data, TSH values, surgery and complications after a 12-month follow-up were analyzed. Results: Thirty-eight patients with goiter were selected for the campaign and 32 patients (mean age, 40-years-old; 30 females) were operated. Bilateral goiter, as assessed with echography, was diagnosed in 13 patients (41%). Ten patients (31%) had a WHO grade II goiter (visible with the neck in a normal position). The surgical procedures were 18 unilateral thyroidectomy with isthmectomie, 13 total thyroidectomy, and 1 totalizing thyroidectomy, due to previous unilateral thyroidectomy (cancer recurrence). A pathological study in 13 patients (40%, extra cost 60 €) showed benign multinodular goiter/thyroid nodule (12 patients) and an extensive papillary carcinoma (one patient). Six months postoperatively, 3 patients had a slight dysphonia and one patient had persistent hypocalcemia. Follow-up was completed in all patients, either face to face (75%, 24 patients) or by phone (25%, 8 patients who failed to have a TSH test because of its cost, 23 €). Conclusions: Surgical campaigns to treat thyroid pathology can be carried out with guarantees if a series of important steps are followed: active participation of the patient's environment, thyroid ultrasound by the surgical team to decide which technique, intense awareness about monitoring and hormone replacement therapy, and the participation of local personnel for long-term follow-up.

Impaired Quality of Life in Patients with Post-Surgical Hypoparathyroidism.

BACKGROUND: Hypoparathyroidism is characterized by chronic hypocalcemia with low or abnormal parathyroid hormone levels. Thyroid surgery remains a predominant cause of hypoparathyroidism, often preventable by partial thyroidectomy. Although hypoparathyroidism can impair quality of life (QOL), data remain limited for Latin America. We aimed to characterize clinical manifestations and QOL in patients with postsurgical hypoparathyroidism. METHODS: This case-control study included patients (>18 years) who underwent total thyroidectomy (TT) for differentiated thyroid cancer (DTC) with postsurgical hypoparathyroidism (Group 1, Cases) and those with DTC who underwent TT without postsurgical hypoparathyroidism (Group 2, Controls). Clinical records were collected, and the SF-36v2 QOL survey and a structured symptom survey were applied. A logistic multivariate regression analysis was performed. RESULTS: This study included 106 subjects (Group 1, N=41; Group 2, N=65). Group 1 patients were younger, had a higher frequency of lymph node resection, and more frequently received Ι-131 than Group 2 patients (p<0.05). In the SF-36v2 survey, Group 1 had fewer physical-functioning scores (odds ratio, 3.8; 95% confidence interval, 1.2-11.7) and lower scores in mental and physical components than Group 2 and national records. Commonly reported symptoms include paresthesia, daily fatigue, and memory alterations. Treatment adherence rates were 56% and 71% for calcium and calcitriol, respectively. Furthermore, 24% of patients experienced one or more hypoparathyroidism drug-related adverse effects. CONCLUSIONS: Patients with postsurgical hypoparathyroidism had an impaired QOL, a high frequency of disease-associated symptoms, and limited treatment adherence. These results should be considered when deciding the best surgical alternative for DTC.

Post-thyroidectomy bilateral cervical plexus block relieves pain: a systematic review.

PURPOSE: To assess the effectiveness of bilateral superficial cervical plexus block (BSCPB) in treating post-thyroidectomy pain. METHODS: MEDLINE, Embase, Google Scholar, LILACS, and the Cochrane Central Register of Controlled Trials, were extensively searched. The search period extended from 1968 until December 2022. Randomized controlled trials comparing BSCPB to placebo, no block in patients with thyroidectomy for benign or malignant thyroid disease were included. Outcomes were pain in the first 24 h after surgery. Analgesic rescue, period before the first rescue dosage, and 24-h opioid usage were secondary outcomes. The RoB 2 instrument was used to evaluate the risk of bias. RESULTS: 34 of 354 studies were eligible. There were 2,519 patients. BSCPB reduced the intensity of pain postoperatively [SMD: - 1.17 (95% CI: - 1.54 to - 0.81)] and in the first 24 h [- 0.62 (95%: 0.91 to 0.33)]. A considerable delay for the first opioid dose, rescue analgesics, and postoperative opioid usage was also found. CONCLUSION: BSCPB's 24-h analgesic efficacy minimizes the requirement for rescue analgesia, postoperative opioid intake, and rescue analgesia start time. The choice of anesthetic and different application methods might affect its effectiveness.

Endoscopic thyroidectomy via chest-collarbone approach versus conventional open thyroidectomy: a retrospective comparative study.

OBJECTIVE(S): Endoscopic thyroidectomy, such as axillary, areola and transoral approaches, offer the advantage of a good cosmetic outcome, but it requires a wider dissection field compared to open thyroidectomy. Recently, chest-collarbone approach thyroidectomy has been widely developed in China because of its shorter anatomical route compared to other endoscopic approaches. This study retrospectively evaluated endoscopic thyroidectomy via chest-collarbone approach in patients with thyroid nodules to determine its feasibility. METHODS: A total of 46 patients with thyroid disease who underwent endoscopic thyroidectomy between January 2022 and December 2022 were enrolled in the study and randomly matched to patients with thyroid disease who underwent open thyroidectomy at the same time based on nodule size and pathology. Postoperative bleeding, hoarseness situation, hospital stay, postoperative drainage volume, laryngeal nerve palsy, hypoparathyroidism and wound infection were assessed in both groups. RESULTS: Forty-four patients underwent endoscopic thyroidectomy successfully and two patients changed to open thyroidectomy. The amount of postoperative drainage for the endoscopic thyroidectomy group was 102.78 ±â€¯28.04 mL, and which was 71.91 ±â€¯19.20 for open thyroidectomy group (p < 0.001). The postoperative hospital stay for the endoscopic thyroidectomy group was 8.78 ±â€¯2.57 days, and which was 7.22 ±â€¯1.13 for open thyroidectomy group (p < 0.001). There was no significant difference in postoperative bleeding, hoarseness situation, and wound infection between the two groups. Laryngeal nerve palsy, supraclavicular nerve injury and hypoparathyroidism were not observed in any patient during this study. CONCLUSION: Chest-collarbone endoscopic thyroid surgery is acceptable. This treatment improves in a good cosmetic outcome in patients with thyroid disease. To assess patients with preoperative nodule size and nature of the case is the impact of the success rate, which is particularly important.

Hyoid Bone Movement During Swallowing in Female Thyroidectomy Patients: A Kinematic Ultrasound Study.

The aim of this study was to investigate the measures of displacement, time and velocity of hyoid bone movement in female thyroidectomy patients. Fifty-eight ultrasound videos of 29 women during swallowing were analyzed. The sample was divided into experimental group (EG), composed of 12 women following total or partial thyroidectomy; and control group (CG) of 17 healthy women. The kinematic measures of displacement, time and velocity of hyoid bone displacement were tracked during swallowing of 10 ml of liquid (water) and 10 ml of thickened liquid (honey) in both groups for comparisons. Additional analysis included bolus consistency effect and relationship with clinical characteristics. Ultrasound videos were analyzed according to a standardized protocol using ImageJ software. Displacement, time and velocity of hyoid movement during swallowing of 10 ml of liquid or thickened liquid were not statistically different between female thyroidectomy patients and healthy women. There is no bolus consistency effect on kinematic measures in both groups, but among thyroidectomy patients, velocity of hyoid bone movement is significantly faster in those with swallowing complaints.

Quality of life of patients with thyroid cancer in Colombia.

INTRODUCTION: Quality of life (QoL) in thyroid cancer patients is comparable to patients with other tumours with worse prognosis. The aim was to evaluate QoL in Colombian patients with thyroid carcinoma and to explore the association of QoL scores with patient features. METHODS: This is a cross-sectional study. The present research was carried out from data obtained for the validation study of the Spanish version of the THYCA-QoL. Adult patients with thyroid carcinoma who underwent total or partial thyroidectomy were included and asked to complete the Spanish-validated versions of the THYCA-QoL and EORTC QLQ-C30 questionnaires. The scores of each domain and single items underwent linear transformation to values of 0-100. Comparisons of scale scores with clinical variables were performed. RESULTS: We included 293 patients. The global EORTC QLQ-C30 score was 73.2±22.1 and the domains with poorer values were emotional and cognitive and the symptoms with poorer values were insomnia and fatigue. The global THYCA-QOL score was 28.4±17.8. The domains with poorer values were neuromuscular and psychological and the single items with poorer values were headaches and tingling hands/feet. CONCLUSION: Colombian patients with thyroid cancer have a good prognosis, but they experience important problems related to QoL. QoL was influenced by demographic and clinical factors such as age, sex functional status and clinical stage.

Transoral endoscopic vestibular approach Sistrunk procedure (TEVAS)-case report and scoping review.

Background: Thyroglossal duct cyst (TGDC) is the most common congenital neck mass among the pediatric population. Less than 10% of the cases occur in adults. The standard of care for TGDC is surgical treatment with the Sistrunk procedure via a traditional transverse cervicotomy. This technique involves the resection of the cyst with its tract and the central portion of the hyoid bone body to avoid recurrence. The transoral vestibular approach has gained popularity as an alternative approach to open neck surgery in order to eliminate the transcervical scar associated with these procedures. Methods: We describe a case of an endoscopic Sistrunk procedure performed by the transoral vestibular approach. A scoping review of the transoral endoscopic vestibular approach Sistrunk procedure (TEVAS) was performed. The PubMed, Medline, Cochrane, Lilacs, Scielo, Mary Ann Libert and Scopus databases were systematically searched by using a Medical Subject Heading (MeSH)-optimized search strategy. The selection of papers followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines after setting inclusion and exclusion criteria. Results: The case was successful and without complications. Five studies were included in the final analysis for this review. Conclusions: This novel approach to the Sistrunk procedure is an effective alternative way to treat TGDC in selected patients who are motivated to avoid a visible neck scar.

Aesthetic Perceptions Regarding a Thyroidectomy Scar and Transvestibular Approach in Brazil.

OBJECTIVE: We investigated motivation levels across the general Brazilian population and subgroups and their willingness to spend for surgery without a cervical scar. METHODS: This random-sample survey was performed by a specialized third-party research institute. In this study, we created a hypothetical thyroidectomy scenario, and the transcervical and transoral endoscopic thyroidectomy vestibular approach (TOETVA) were used. The survey included sociocultural data and questions regarding participants' surgical preferences. RESULTS: Data were obtained from 1250 participants; 42.4% were of the opinion that a cervical scar affects social or professional life. Young and childless women were most likely to be affected (p <0.001). All respondents accepted the transoral approach to avoid cervical scarring. However, 30.7% and 31.9% of respondents maintained their preference for TOETVA despite understanding the risks of a hypothetical increase in complications and unfavorable oncological outcomes and 98.6% were of the opinion that this approach was likely associated with greater postoperative pain. Only 16.2% were unwilling to spend for TOETVA. The variable that most affected patients' willingness to spend was a salary greater than 10 Brazilian minimum wages (odds ratio 9.797, 95% confidence interval, p <0.005). Upper class respondents were 10 times more likely to spend for TOETVA than lower class patients. CONCLUSION: This study highlights patients' interest in TOETVA. Cervical scar perception is affected by concerned about appearance, particularly in certain societal subgroups. Our study population showed significant motivation to undergo TOETVA, which was emphasized by their acceptance of the complication rate, poor postoperative outcomes, greater postoperative pain, and willingness to spend on surgery with an invisible scar.

Assessing Symptomatic Hypocalcemia Risk After Total Thyroidectomy: A Prospective Study.

Introduction The most common postoperative complication of total thyroidectomy is hypocalcemia, usually monitored using serum parathyroid hormone and calcium values. Objective To identify the most accurate predictors of hypocalcemia, construct a risk assesment algorithm and analyze the impact of using several calcium correction formulas in practice. Methods A prospective, single-center, non-randomized longitudinal cohort study on 205 patients undergoing total thyroidectomy. Parathyroid hormone, serum, and ionized calcium were sampled post-surgery, with the presence of symptomatic or laboratory-verified asymptomatic hypocalcemia designated as primary outcome measures. Results Parathyroid hormone sampled on the first postoperative day was the most sensitive predictor of symptomatic hypocalcemia development (sensitivity 80.22%, cut-off value ≤2.03 pmol/L). A combination of serum calcium and parathyroid concentration sampled on the first postoperative day predicted the development of hypocalcemia during recovery with the highest sensitivity and specificity (94% sensitivity, cut-off ≤2.1 mmol/L, and 89% specificity, cut-off ≤1.55 pmol/L, respectively). The use of algorithms and correction formulas did not improve the accuracy of predicting symptomatic or asymptomatic hypocalcemia. Conclusions The most sensitive predictor of symptomatic hypocalcemia present on the fifth postoperative day was PTH sampled on the first postoperative day. The need for algorithms and correction formulas is limited.

Post-thyroidectomy pain relief is enhanced by wound infiltration. A systematic review of randomized controlled trials.

INTRODUCTION: Thyroidectomy is a common surgical procedure. Traditional options for pain management, such as analgesics and nonsteroidal anti-inflammatory medications (NSAIDs), are limited by their side effects. Surgical wound infiltration with local anesthetics has the potential to reduce the need for analgesics in a number of surgical procedures. This systematic review and meta-analysis wanted to resolve these concerns and assess the efficacy of WI in the management of postoperative pain after thyroidectomy. MATERIAL AND METHODS: The review adhered to Cochrane Collaboration and PRISMA standards. RCTs comparing WI with no infiltration or placebo were included. Patients with benign or malignant thyroid disease who underwent open thyroidectomy were eligible. Postoperative pain was assessed using a visual analogue scale (VAS) as the primary outcome. Time to first rescue dose, the need for analgesic rescue in the first 24 h, and total opioid analgesic consumption were secondary outcomes. Standardized mean difference (SMD) and odds ratio (OR) were used to analyze the data. RESULTS: 16 randomized controlled trials involving 1202 patients were included. At 6 and 8 h postoperatively, WI exhibited a statistically significant impact on pain management. In the WI group, the need for analgesic rescue was significantly reduced. At 4 h postoperatively, non-anesthetic medications demonstrated a significant analgesic effect. CONCLUSIONS: This systematic review and meta-analysis support the use of WI with local anesthetics for postoperative pain management after thyroidectomy. These findings have significant implications for improving perioperative care, especially in ambulatory settings where effective pain management is essential.

Surgical safety and effectiveness of bilateral axillo-breast approach robotic thyroidectomy: a systematic review and meta-analysis.

OBJECTIVES: To assess the safety and effectiveness of bilateral axillo-breast approach robotic thyroidectomy in thyroid tumor. METHODS: Bilateral axillo-breast approach robotic thyroidectomy and other approaches (open thyroidectomy, transoral robotic thyroidectomy, and bilateral axillo-breast approach endoscopic thyroidectomy) were compared in studies from 6 databases. RESULTS: Twenty-two studies (8830 individuals) were included. Bilateral axillo-breast approach robotic thyroidectomy had longer operation time, greater cosmetic satisfaction, and reduced transient hypoparathyroidism than conventional open thyroidectomy. Compared to bilateral axillo-breast approach endoscopic thyroidectomy, bilateral axillo-breast approach robotic thyroidectomy had greater amount of drainage, lower chances of transient vocal cord palsy and permanent hypothyroidism, and better surgical completeness (postopertive thyroblobulin level and lymph node removal). Bilateral axillo-breast approach robotic thyroidectomy induced greater postoperative drainage and greater patient dissatisfaction than transoral robotic thyroidectomy. CONCLUSION: Bilateral axillo-breast approach robotic thyroidectomy is inferior to transoral robotic thyroidectomy in drainage and cosmetic satisfaction but superior to bilateral axillo-breast approach endoscopic thyroidectomy in surgical performance. Its operation time is longer, but its cosmetic satisfaction is higher than open thyroidectomy.

Development of a tool to calculate the probability of hypocalcemia after total thyroidectomy: a prospective study.

PURPOSE: This study aimed to evaluate the ability of the percentage of decrease in serum PTH level in the first 8 h after total thyroidectomy (TT) to predict hypocalcemia requiring Ca supplementation and develop a tool to predict it. METHODS: 97 patients who underwent TT with measurement of preoperative parathyroid hormone (PTH) levels were prospectively evaluated 1 and 8 h after TT; postoperative magnesium (Mg2PO) and phosphorus levels were evaluated on the 2nd day after surgery. The percentage of decrease in PTH level 1 h (%dPTH1h) and 8 h (%dPTH8h) postoperatively and predictors of hypocalcemia requiring Ca supplementation were evaluated and an equation was developed to predict this outcome. RESULTS: %dPTH1h (p = 0.002), %dPTH8h (p = 0.001) and (Mg2PO) (p < 0.01) were isolated predictors of postoperative hypocalcemia requiring Ca supplementation. The data obtained led to the development of two tools to predict this complication. CONCLUSIONS: The percentage of decrease in PTH level 1 h and 8 h postoperatively and the magnesium level on the 2nd day after surgery were predictors of more severe hypocalcemia, and an auxiliary tool for predicting this complication was developed.

Fluorescence imaging to visualize the recurrent laryngeal nerve during thyroidectomy procedures: analysis of 65 cases and 81 nerves.

BACKGROUND: Recurrent laryngeal nerve (RLN) injury after thyroidectomy is relatively common. Locating the RLN prior to thyroid dissection is paramount to avoid injury. We developed a fluorescence imaging system that permits nerve autofluorescence. We aimed to determine the sensitivity and specificity of fluorescence imaging at detecting the RLN relative to thyroid and other background tissue and compared it to white light. METHODS: In this prospective study, 65 patients underwent thyroidectomy from January to April 2022 (16 bilateral thyroid resections) using white and fluorescent light. Fluorescence intensity [relative fluorescence units (RFU)] was recorded for RLN, thyroid, and background. RFU mean, minimum, and maximum values were calculated using Image J software. Thirty randomly selected pairs of white and fluorescent light images were independently reviewed by two examiners to compare RLN detection rate, number of branches, and length and minimum width of nerves visualized. Parametric and nonparametric statistical analysis was performed. RESULTS: All 81 RNLs observed were visualized more clearly under fluorescence (mean intensity, µ = 134.3 RFU) than either thyroid (µ = 33.7, p < 0.001) or background (µ = 14.4, p < 0.001). Forest plots revealed no overlap between RLN intensity and that of either other tissue. Sensitivity and specificity for RLN were 100%. All 30 RLNs and all 45 nerve branches were clearly visualized under fluorescence, versus 17 and 22, respectively, with white light (both p < 0.001). Visible nerve length was 2.5 × as great with fluorescence as with white light (µ = 1.90 vs. 0.76 cm, p < 0.001). CONCLUSIONS: In 65 patients and 81 nerves, RLN detection was markedly and consistently enhanced with autofluorescence neuro-imaging during thyroidectomy, with 100% sensitivity and specificity.

Ablation techniques or active surveillance compared to surgical resection in patients with low-risk papillary thyroid cancer: a systematic review and meta-analysis.

BACKGROUND: The global prevalence of thyroid cancer is on the rise. About one-third of newly diagnosed thyroid cancer cases comprise low-risk papillary thyroid cancer (1.5 cm or more minor). While surgical removal remains the prevailing approach for managing low-risk papillary thyroid cancer (LPTC) in patients, other options such as active surveillance (AS), radiofrequency ablation (RFA), microwave ablation (MWA), and laser ablation (LA) are also being considered as viable alternatives. This study evaluated and compared surgical thyroid resection (TSR) versus non-surgical (NS) methods for treating patients with LPTC. METHODS: The study encompassed an analysis of comparisons between surgical thyroid resection (TSR) and alternative approaches, including active surveillance (AS), radiofrequency ablation (RFA), microwave ablation (MWA), or laser ablation (LA). The focus was on patients with biopsy-confirmed low-risk papillary thyroid cancer (LPTC) of less than 1.5 cm without preoperative indications of local or distant metastasis. The primary outcomes assessed were recurrence rates, disease-specific mortality, and quality of life (QoL). Data were collected from prominent databases, including Cochrane Database, Embase, MEDLINE, and Scopus, from inception to June 3rd, 2020. The CLARITY tool was utilized to evaluate bias risk. The analysis involved odds ratios (OR) with 95% confidence intervals (CI) for dichotomous outcomes, as well as mean differences (MD) and standardized mean differences (SMD) for continuous outcomes. The study is registered on PROSPERO under the identifier CRD42021235657. RESULTS: The study incorporated 13 retrospective cohort studies involving 4034 patients. Surgical thyroid resection (TSR), active surveillance (AS), and minimally invasive techniques like radiofrequency ablation (RFA), microwave ablation (MWA), and laser ablation (LA) were performed in varying proportions of cases. The analysis indicated that specific disease mortality rates were comparable among AS, MWA, and TSR groups. The risk of recurrence, evaluated over different follow-up periods, showed no significant differences when comparing AS, RFA, MWA, or LA against TSR. Patients undergoing AS demonstrated better physical health-related quality of life (QoL) than those undergoing TSR. However, no substantial differences were observed in the overall mental health domain of QoL when comparing AS or RFA with TSR. The risk of bias was moderate in nine studies and high in four. CONCLUSION: Low-quality evidence indicates comparable recurrence and disease-specific mortality risks among patients with LPTC who underwent ablation techniques or active surveillance (AS) compared to surgery. Nevertheless, individuals who opted for AS exhibited enhanced physical quality of life (QoL). Subsequent investigations are warranted to validate these findings.

Thyroid surgery in children: a single-center experience of 20 years

SUMMARY OBJECTIVE: Thyroidectomy is a relatively uncommon procedure in pediatric patients. We aimed to review our 20-year experience of thyroid surgery. METHODS: A total of 39 patients who underwent thyroid surgery from 2003 to 2023 were retrospectively evaluated. All patients were followed preoperatively and postoperatively by our institutional multidisciplinary board. Patients were divided into two groups based on their pathologies: benign and malignant. RESULTS: In total, 39 patients (27 girls and 12 boys) underwent 47 thyroid surgeries (total thyroidectomy in 19 patients and subtotal thyroidectomy in 20 patients, with 8 of them having completion thyroidectomy). Notably, 20 (51%) patients had benign and 19 (49%) patients had malignant pathologies. Median age at operation was 157 (9-223) months in the benign group and 182 (1-213) months in the malignant group. In the benign group, 12 (60%) patients had colloidal goiter and 8 (40%) patients had other conditions. In the malignant group, 12 (63%) patients had papillary thyroid carcinoma, 3 (16%) patients had follicular thyroid carcinoma, 2 (11%) had medullary thyroid carcinoma, and 2 patients had other thyroid malignancies. Overall permanent complication rate was 2 out of 39 (5%), which was similar for both groups (1 hypocalcemia in each group). The median follow-up was 38 months (1-179 months) with no local recurrence or distant metastasis. CONCLUSION: Pediatric thyroidectomies are performed on a heterogeneous group of pediatric patients due to a diverse group of pathologies. A multidisciplinary approach is required for proper initial management and surgical strategy with decreased complication rate and event-free survival of these patients in experienced tertiary centers.
