Outcomes of Total Thyroidectomy in Large Goiters With Retrosternal Extension and Tracheal Compression: A Multivariate Analysis.

Large retrosternal goiters often cause tracheal compression and deviation, leading to respiratory symptoms and complicating surgical treatment. Total thyroidectomy is the treatment of choice though it carries a risk of complications due to the altered anatomy and its proximity to vital structures. This study examines the outcomes of total thyroidectomy in patients with retrosternal goiters and assesses the impact of tracheal compression on clinical results. This retrospective study included 32 patients treated with total thyroidectomy for retrosternal goiter between January 2018 and June 2024. Patient records were analyzed for clinical presentation, tracheal status, extent of retrosternal extension, intubation details, surgery performed, intraoperative findings, and postoperative complications. Tracheal compression and deviation were noted by preoperative imaging and flexible fiberoptic bronchoscopy. A correlation between difficult intubation and tracheal status was attempted. Complications such as hypocalcemia, recurrent laryngeal nerve palsy, and tracheomalacia were assessed alongside surgical variables. Among the 32 patients, tracheal deviation was noted in 62.5% (n=20), and tracheal compression occurred in 43.8% (n=14). Complications included hypocalcemia in 43.8% (n=14) of cases, recurrent laryngeal nerve palsy in 6.25% (n=2), and tracheomalacia in 15.6% (n=5). Advanced airway management techniques such as flexible fiberoptic-assisted intubation were often required, particularly in cases with significant tracheal compression. Malignant goiters showed a higher incidence of tracheal deviation and postoperative complications but overall complication rates were comparable to benign cases. Large retrosternal goiters carry the risk of airway compromise and surgical complications, particularly in the presence of tracheal compression. Hence, preoperative assessment of tracheal involvement and tailored surgical approaches are essential to manage airway complications and improve postoperative outcomes. A multidisciplinary approach is recommended for the management of these cases to enhance patient outcomes.

Surgical Outcomes in Thyroidectomy for Patients with Graves’ Disease: A Randomized Controlled Trial

Background: Thyroidectomy is a preferred protocol for patients with Graves’ disease. However, it may be a challenging option in post-surgical management of various factors. There, this study aims to compare the surgical outcomes of total thyroidectomy and subtotal thyroidectomy in patients with Graves’ disease to provide evidence-based surgical decision-making. Methods: This randomized controlled trial was conducted at Sheikh Zaid Hospital, Rahim Yar Khan, October 2023 to April 2024; enrolled 120 patients diagnosed with Graves’ disease using a simple random sampling technique were assigned to Group A (n=60) and B (n=60) who underwent total thyroidectomy, and subtotal thyroidectomy respectively. Preoperative assessments and surgeries were performed while postoperative outcomes, complications, and thyroid function tests were also monitored and represented using independent t-tests while a p<0.05 was considered significant. Results: It was revealed that operative time was significantly higher for total thyroidectomy than subtotal thyroidectomy 125.60±14.56 and 97.54±12.56 respectively, suggesting significantly lower time consumption in subtotal thyroidectomy procedure (p=0.001). Patients who underwent subtotal thyroidectomy had a significantly shorter hospital stay compared to those who underwent total thyroidectomy (p=0.02). Moreover, levels of triiodothyronine (T3), thyroxine (T4), and thyroid-stimulating hormone (TSH) were significantly different between the two groups. Patients who underwent subtotal thyroidectomy had significantly lower T3 and T4 levels and higher TSH levels compared to those who underwent total thyroidectomy (p<0.05). Conclusion: Subtotal thyroidectomy demonstrated favorable outcomes, including shorter operative time, lower rates of postoperative complications, and thyroid function tests compared to total thyroidectomy. These findings help and support the consideration of subtotal thyroidectomy as a viable surgical approach for patients with Graves' disease.

National Trends and Outcomes in the Operative Management of Thyroid Storm.

Thyroid storm is a rare but potentially lethal manifestation of thyrotoxicosis. Guidelines recommend nonoperative management of thyroid storm, but thyroidectomy can be performed if patients fail medical therapy or need immediate resolution of the storm. Outcomes of thyroidectomy for management of thyroid storm remain ill-defined. Using the National Inpatient Sample from 2016 to 2020, a retrospective analysis was conducted of patients admitted with thyroid storm. Outcomes of interest included operative complications and mortality. Multivariable logistic regression was performed to assess factors associated with receiving thyroidectomy and mortality. An estimated 16,175 admissions had a diagnosis of thyroid storm. The incidence of thyroid storm increased from .91 per 100,000 people in 2016 to 1.03 per 100,000 people in 2020, with a concomitant increase in mortality from 2.9% to 5.3% (P < .001). Operative intervention was pursued in 635 (3.9%) cases with a perioperative complication rate of 30%. On multivariable regression, development of acute decompensated heart failure (adjusted odds ratio [AOR] 1.66, 95% Confidence Interval [CI] 1.03-2.68, P = .037) and acute renal failure (AOR 2.10, 95% CI 1.17-3.75, P = .013) increased odds of receiving surgery. The same multivariable model did not show a significant association between thyroidectomy and mortality. The incidence of thyroid storm and associated mortality increased during the study period. Thyroidectomy is rarely performed during the same admission, with an overall perioperative complication rate of 30% and no effect on mortality. Patients with acute decompensated heart failure and renal failure were more likely to receive an operative intervention.

The effect of total thyroidectomy and radioactive iodine on long-term survival in unilateral T3/T4 follicular thyroid carcinoma: insights from a propensity-matched retrospective analysis.

Follicular thyroid carcinoma (FTC) is the second most common thyroid malignancy and is particularly aggressive in advanced stages such as T3 and T4. This retrospective study aimed to evaluate the long-term survival outcomes of total thyroidectomy (TT) and radioactive iodine therapy (RAIT) in unilateral T3 or T4 FTC using propensity score-matched analysis. Utilizing the Surveillance, Epidemiology, and End Results (SEER) database, we identified patients diagnosed with T3 or T4 FTC and categorized them into two cohorts, namely those who were treated with TT and those who were not (non-TT). The non-TT group was further analyzed to determine the impact of RAIT on survival. Propensity score matching (PSM) was applied to adjust for confounding variables. Survival analysis, including Kaplan-Meier survival curves and landmark analysis, evaluated the effects on overall survival (OS) and cancer-specific survival (CSS). A total of 2,957 patients were included, with 2,271 (76.8%) undergoing TT and 686 (23.2%) receiving alternative treatments. Before and after PSM, there were no significant differences in OS and CSS between the two groups. Post-PSM landmark analysis revealed that beyond 90 months, the TT group had superior CSS compared with the non-TT group (P=0.06). Cox multivariate regression identified follicular adenocarcinoma trabecular [hazard ratio (HR) =4.7041; 95% confidence interval (CI): 1.1218-19.727] and minimally invasive follicular carcinoma (HR =2.0202; 95% CI: 1.2140-3.362) as independent risk factors affecting prognosis. In the second part of the study, 671 patients were analyzed, namely 197 (29.4%) who received RAIT and 474 (70.6%) who did not. Landmark analysis indicated that after 30 months, the RAIT group had superior CSS compared with the non-RAIT group (P<0.05). TT does not improve the survival rates of patients with stage T3/T4 FTC. For those patients who have not undergone TT, RAIT proves beneficial for CSS; however, further in-depth studies are required.

Surgical Outcomes of Thyroidectomy in Geriatric Patients Aged 80 Years and Older: A Single-Center Retrospective Cohort Study.

Background and Objectives: As the global aging population grows, the incidence of thyroidectomy in elderly patients is increasing. This study aimed to evaluate the surgical outcomes of thyroidectomy in patients aged 80 years and older. Materials and Methods: All patients aged 80 years and older who underwent thyroidectomies at our hospital between January 2015 and December 2022 were reviewed in this retrospective cohort study. Collected data consisted of patients' clinical characteristics, functional status, compression symptoms, preoperative assessments, perioperative outcomes, postoperative complications (such as bleeding events, recurrent laryngeal nerve injury, hypocalcemia), pathological findings, readmission, and follow-up outcomes. Results: Seventeen patients were included in this study, with female predominance (82.4%). The mean age was 85.6 ± 4.8 years. Fourteen patients (82.4%) exhibited compression-related symptoms as surgical indications. Based on pathological reports, patients were categorized into benign (12/17, 70.6%) and malignancy (5/17, 29.4%) groups. The benign group had a shorter operation time compared with the malignancy group (164.3 ± 32.0 min vs. 231.0 ± 79.1 min, p = 0.048). No major postoperative complications developed. The median postoperative follow-up duration was 28 months (range: 2-91 months). Thirteen patients (76.5%) were alive at the end of the study period. Conclusions: Despite potential age-related risks, thyroidectomy is feasible for carefully selected patients aged 80 years and older. It provides benefits not only in terms of oncological curative treatment but also in improving the quality of life, such as compressive symptoms and wound condition.

Outcomes of thyroidectomy in symptomatic, euthyroid Hashimoto's patients: a case control study.

Hashimoto's thyroiditis (HT) is managed with thyroid hormone replacement to maintain a euthyroid state. A subset of patients have refractory symptoms, which improve with thyroidectomy (TT). There remains a reluctance to proceed with surgery due to perceptions of complications, and limited data availability regarding improvements in quality of life (QoL). This retrospective case control study aims to analyse the outcomes and QoL scores for symptomatic euthyroid HT patients who underwent TT. Thirty euthyroid patients who underwent TT for the management of HT between 2017 and 2022 were identified. An age-matched control group of patients who underwent TT for symptomatic multinodular goitre (MNG) were randomly selected. Demographics, biochemistry, histology, outcomes, and pre- and post-operative SF-36 and ThyPRO-39 scores were compared between groups. There were no surgical complications in the HT group, whilst two MNG patients had complications. There was a similar rate of parathyroid auto-transplantation in both groups, more glands were transplanted in the HT group. There was a significant difference in pre- and post-operative QoL scores for both groups. Comparison revealed a significant improvement in hyperthyroid symptoms, social life and daily life scores in the HT group. There was a significant difference in pre- and post-operative anti-TPO, anti-TG and TSH levels in the HT group. Patients with symptomatic Hashimoto's thyroiditis, despite being euthyroid, may benefit from total thyroidectomy however this remains under-utilized. This study demonstrated that thyroidectomy was associated with an improvement in validated post-operative quality of life scores and was not associated with increased complication rates for appropriately selected patients.

Surgical outcomes of robotic thyroidectomy for thyroid tumors over 4 cm via the bilateral axillo-breast approach

The study investigated the feasibility of robotic bilateral axillo-breast approach (BABA) thyroidectomy for patients with thyroid tumors larger than 4 cm. BABA thyroidectomy has previously shown safety and effectiveness for thyroid surgeries but lacked extensive data on its application to larger tumors. Between October 2008 and August 2022, there were 74 patients underwent robotic BABA thyroidectomy due to thyroid nodules exceeding 4 cm in size. The mean patient age was 40.3 years. Fine needle aspiration results classified the tumors as benign (50.0%), atypia of undetermined significance (27.0%), follicular neoplasm (16.2%), suspicious for malignancy/malignancy (5.4%), or lymphoma (1.4%). The average tumor size was 4.9 cm, with the majority (85.1%) undergoing thyroid lobectomy, and the rest (14.9%) receiving total thyroidectomy. The mean total operation time was 178.4 min for lobectomy and 207.3 min for total thyroidectomy. Transient vocal cord palsy (VCP) was found in 3 patients (4.1%), and there was no permanent VCP. Among patients who underwent total thyroidectomy, transient hypoparathyroidism was observed in three (27.2%), and permanent hypoparathyroidism was observed in one (9.1%). There were no cases of open conversion, tumor spillage, bleeding, flap injury, or tumor recurrence. In conclusion, robotic BABA thyroidectomy may be a safe treatment option for large-sized thyroid tumors that carries no significant increase in complication rates.

Trends and postoperative outcomes of thyroidectomy after expansion and rise of health insurance deductibles in the fiscal year

BackgroundThe purpose of this study is to evaluate a relationship between expansion of High Deductible Health Plans (HDHPs) and the number of thyroid surgery cases with associated postoperative outcomes in the fiscal year. MethodsData from TriNetX was used to evaluate the trends in thyroid surgery from 2005 and 2021 between the end of the year (Quarter 4) and the beginning of the year (Quarter 1). Risk of postoperative outcomes were statistically interrogated. ResultsThe average rate of thyroid surgery in cases/year between Quarter 4 and Quarter 1 was similar after expansion of HDHPs (152; 146; p = 0.64). There was no increased risk of postoperative complications. The rate of surgery decreased significantly for patients with Medicare after implementation of the revised American Thyroid Association (ATA) guidelines (Quarter 4: p = 0.03; Quarter 1: p = 0.02). ConclusionsPatients are less likely to delay thyroid surgery at the end of the year despite higher deductibles.

Outcomes of thyroidectomy for secondary thyroid malignancies, a single center experience

BackgroundMetastasis of primary malignancies of other organs to the thyroid gland is a rare condition that may pose a diagnostic challenge. In this study, we aimed to report the clinicopathologic features and outcomes of patients treated for secondary thyroid malignancies in our center.Materials and methodsThe results of patients who underwent thyroidectomy in our clinic between 2015 and 2023 were evaluated retrospectively. Four patients who met the inclusion criteria were evaluated.ResultsThe primary tumor was renal cell carcinoma in 2 patients and squamous cell carcinoma of the lung in 2 patients. Median age was 64 years (min:59–max:69). The median nodule diameter was 2.85 cm. Extrathyroidal spread was present in 1 patient with renal cell carcinoma metastasis. The other patient with renal cell carcinoma metastasis had lymphatic invasion. Vascular invasion was detected in 1 patient with renal cell carcinoma metastasis and 1 patient with squamous cell carcinoma of the lung metastasis. Surgical margin positivity was present in 1 patient in each group. The median overall survival time was 27 (min:10–max:44) months in the renal cell carcinoma group and 11 (min:6–max:16) months in the squamous cell carcinoma group. After the diagnosis of primary renal cell carcinoma, one patient metastasized to thyroid tissue 43.00 and one patient 94.00 months later. In the squamous cell carcinoma group, one patient showed metastasis to thyroid tissue 6.00 months after the primary diagnosis, while the other patient was first diagnosed with metastatic tissue.ConclusionsMetastasis to the thyroid gland is a rare phenomenon with an incidence of 0.22% in all thyroid malignancies. It may occur before the detection of the primary tumor or during the follow-up of the primary malignancy. Although the overall prognosis is poor, it can be treated surgically.

Limited English Proficiency and Graves’ Disease at an Urban Safety Net Hospital

IntroductionDecision-making regarding definitive therapy for Graves’ disease requires effective patient-provider communication. We investigated whether patients with limited English proficiency have differences in thyroidectomy outcomes or perioperative management when compared to English proficient (EP) patients at a safety net hospital with high-volume endocrine surgery practice. MethodsRetrospective study of patients who underwent thyroidectomy (2012-2021) for Graves’ disease within a tertiary referral system. Demographics, preoperative factors, and postoperative outcomes were abstracted via chart review and compared between EP and limited English proficient (LEP) patients in univariate analyses. Odds of postoperative complications were assessed via multivariable logistic regression. Time metrics such as time from endocrinology consultation to surgery were compared via Kaplan–Meier analysis and adjusted Cox proportional regression models. ResultsOf 236 patients, 85 (36%) had LEP. Low and equivalent complication rates occurred across language groups (<1% permanent). LEP patients had similar odds of thyroidectomy-specific complications (odds ratio = 1.2; 95% confidence interval 0.6-2.4). Adjusted Cox proportional hazards ratios showed that LEP patients experienced significantly shorter time from endocrinology consultation to surgery compared to EP patients [hazard ratio = 0.7; 95% confidence interval 0.5-0.9]. ConclusionsThyroidectomy-specific complication rate for patients with Graves’ disease was low, and we detected no independent association between complications and English language proficiency. Non-English primary language was independently associated with reduced time from endocrinology consultation to surgery. This finding must be interpreted with nuance and is likely multifactorial. It may reflect a well-organized, efficient system for under-resourced patients, or it may derive from communication barriers that limit robust shared decision-making, thus accelerating time to surgery.

Perioperative outcomes of bilateral axillo-breast approach robotic thyroidectomy (BABART) versus minimally invasive thyroidectomy (MIT): a systematic review and meta-analysis.

Minimally invasive thyroidectomy (MIT) is increasingly being used for the thyroid tumors. The comparison of bilateral axillo-breast approach robotic thyroidectomy (BABART) with other MIT has not yet led to a unified conclusion with regard to surgical outcomes. To conduct a systematic review and meta-analysis of the literature on the surgical outcomes of BABART compared with MIT. We performed a systematic search in PubMed, Web of Science, Embase and Cochrane Library database for randomized control trials (RCTs) and non-RCTs that compare BABART to MIT. The primary outcomes included perioperative, postoperative complications. The odds ratio (OR) and mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CIs). Nine studies, comprising 3645 patients, were included in the meta-analysis. Our findings indicated that there were no significant differences in hospital stay, number of retrieved lymph nodes, recurrent laryngeal nerve (RLN) injury, and vocal cord dysfunction between BABRT and MIT. However, BABART was associated with a shorter operation time (MD = - 21.45min, 95% CI [- 47.27, 4.38], p = 0.1) and lower rate of permanent hypoparathyroidism (OR = 0.42, 95% CI [0.20, 0.88], p = 0.02). Additionally, the MIT group had reduced postoperative pain score (MD = 0.45, 95% CI [0.02, 0.88], p = 0.04) and lower rate of hypocalcemia (OR = 2.31, 95% CI [1.04, 5.13], p = 0.04) than the BABART group. In comparison with MIT, BABART exhibits better results in terms of operative time and the rate of permanent hypoparathyroidism, with no significant difference in hospital stay, number of retrieved lymph nodes, RLN injury, and vocal cord dysfunction. However, the postoperative pain score and the rate of hypocalcemia of MIT are slightly better that of BABART.

The anterior neck scar outcomes of conventional thyroidectomy using a wound protector: a multicenter double-blinded randomized controlled trial.

This study aimed to investigate the effectiveness of a novel wound protector in enhancing the cosmetic outcomes of thyroidectomy. This multicenter, double-blinded randomized controlled trial enrolled 129 patients undergoing open thyroidectomy. The patients were divided into a wound protector group and a control group. Subjective patient assessments were conducted, measuring wound satisfaction, pain, and itchiness. Additionally, blinded observers evaluated scars using the Vancouver Scar Scale. The Vancouver Scar Scale revealed significant advantages for the wound protector group, demonstrating improvements in pigmentation ( P =0.002), vascularity ( P =0.014), pliability ( P =0.001), and height ( P =0.001). The thyroid wound protector offers a potential to improve postoperative cosmetic outcomes. Further research is warranted to explore patient experiences and optimize the application of this innovative wound protector across diverse surgical contexts.

Assessment of Patients' Quality-of-Life Post-Thyroidectomy.

The assessment of quality of life (QOL) after thyroidectomy has been a focus of medical research, aiming to understand its impact on patients' overall well-being and functional status. Studies have examined the physical, psychological, and social dimensions of QOL, providing valuable insights into the outcomes of thyroidectomy and improving patient care.The aim of the study is to evaluate the long-term impact of different aspects of patients' quality of life post-thyroidectomy. This cross-sectional study was conducted in Taif City and included 100 participants post-thyroidectomy. Data were collected from medical records and telephone interviews using the modified Arabic version of the EROTC QLQ-H&N43 questionnaire. The collected data were analyzed using R software version 4.2.2. The majority of the 100 participants were female (76%), and most were over 50 years old (38%). The types of surgery performed included hemithyroidectomy (36%), subtotal thyroidectomy (6%), and total thyroidectomy (58%). Participants reported difficulties related to their senses, body satisfaction, sexual satisfaction, eating, speaking, and social interactions. Pain in the mouth and jaw, as well as swallowing difficulties, showed variations among the surgery groups. Other symptoms, such as tooth problems, dry mouth, and swelling in the neck, did not differ significantly among the groups. Numbness in the hands or feet was associated with a subtotal or total thyroidectomy. Difficulties with enjoying meals, eating in front of others, and communication issues showed variations among the surgery groups. This study provided insights into the QOL of thyroidectomy survivors in Taif City. Participants reported challenges related to sensory, body, and sexual issues, as well as difficulties with eating, speaking, and social interactions. The findings highlight the need for interventions and support to address these challenges and optimize the QOL of thyroidectomy patients. Furthermore, research is warranted to explore specific factors contributing to these difficulties and to develop targeted interventions for better patient outcomes.

Comparing the outcomes of total thyroidectomy using a harmonic scalpel versus the conventional ligation techniques in Iran

Background: Maintaining hemostasis is considered a remarkable challenge during total thyroidectomy. The use of thermal ultrasonic electrocoagulation (harmonic scalpel) for total thyroidectomy was recently introduced to substitute the conventional ligation methods. However, controversies exist on the efficacy of this technique compared to the classic method.&#x0D; Methods: The data regarding this prospective cohort study was gathered between March 2019 to March 2020. Ninety participants were enrolled in the study. Forty-five subjects received harmonic scalpel ligation and the other forty-five participants underwent conventional total thyroidectomy. Afterward, these two groups were statistically compared regarding surgical time, postoperative hypocalcemia, drainage volume, postoperative pain, hospital stay, and recurrent nerve damage.&#x0D; Results: No significant difference was detected in the group undergoing harmonic ligation concerning postoperative pain, postoperative hospital stay, drainage volume, and postoperative hypocalcemia in the first 48 hours post-operation. However, using a harmonic scalpel significantly reduced the surgical time (56 ± 2 minutes in the harmonic scalpel group versus 67 ± 9 in the conventional technique group, p &lt; 0.001). Also, no recurrent nerve damage was detected in the study.&#x0D; Conclusions: Utilizing a harmonic scalpel has a remarkably higher time efficacy in total thyroidectomy. However, the study suggests no further advantage for this method compared to the conventional techniques in total thyroidectomy.

Thyroidectomy Outcomes in Obese Patients

IntroductionObese patients often have higher complication rates after elective general surgeries; however, few studies have examined the outcomes after thyroidectomy. This study examines whether increased body mass index (BMI) is associated with poor postoperative outcomes after thyroid surgery. MethodsA retrospective review of patients who underwent thyroidectomy from 2015 to 2018 was performed. Demographics, comorbidities, pathology, and extent of resection (total versus hemithyroidectomy) were examined. Patients were classified into BMI groups according to the WHO definitions, and the incidence of surgical outcomes was determined in each group. Surgical outcomes of interest included readmission rates (RRs), length of stay, average operating room time, return to the operating room, hypocalcemia, postop infections, hematomas, and recurrent laryngeal nerve injury. Between-subjects statistics including independent samples t-test, ANOVA, and chi-square analyses were performed. ResultsThere were n = 465 patients included with a mean BMI 32.35 (standard deviation = 8.55) and median BMI 30.78 (Q1 = 26.26, Q3 = 36.73). There were no differences between BMI groups in age, gender, smoking, heart disease. There was a positive association between increased BMI and postoperative infection (P < 0.001), pneumonia (P = 0.018), and surgical site infection (P = 0.04), which were highest for BMI > 40. Increased BMI was associated with a higher 30-d RR (P = 0.008), particularly for BMI >40 versus BMI <40 (6.2% versus 1.05%; P = 0.003). There were no significant differences between surgical outcomes for patients with increased BMI who underwent total thyroidectomy or hemithyroidectomy. ConclusionsExcellent postoperative outcomes were observed in all BMI categories. Higher postoperative infection and 30-d RRs were observed in the morbidly obese. Contrary to previous studies, operating room times were similar regardless of BMI.

The impact of obesity on thyroidectomy outcomes: a case-matched study

Obesity is a well-known public health concern in Western World. Accordingly, an elevated number of obese patients undergo thyroidectomy every year. We aim to assess the impact of obesity on intraoperative and postoperative outcomes of patients who undergo thyroidectomy. 1228 patients underwent thyroidectomy at our department between January 2021 and September 2021. We divided patients into two groups according to body mass index (BMI): non-obese (BMI < 30 kg/m2) and obese (BMI ≥ 30 kg/m2). A propensity score approach was performed to create 1:1 matched pairs (matching according to age, gender, diagnosis, nodule size and type of operation). After matching, the final population included 522 patients, equally divided between each group: non-obese group (Group A; n = 261) and obese group (Group B; n = 261). The primary endpoint of the study was the overall rate of postoperative complications; secondary endpoints of the study were operative time, use of energy device and length of hospital stay. The duration of hospital stay resulted longer in Group B (p = 0.002). No statistically significant differences were documented in terms of operative time (p = 0.206), use of energy devices (p = 0.855) and surgical complications (p = 0.429). Moreover, no statistically significant differences were documented considering each specific complication: transient and permanent hypocalcemia (p = 0.336; p = 0.813, respectively), transient and permanent recurrent laryngeal nerve palsy (p = 0.483; p = 0.523, respectively), hematoma (p = 0.779), bleeding (p = 0.178), wound infection (p = 0.313) and cheloid formation (p = 0.412). Thyroidectomy can safely be performed in obese patients. Outcomes resulted comparable; nonetheless, obesity correlates to longer hospital stay.
