The perception of scar cosmesis following thyroid and parathyroid surgery: A prospective cohort study

A prospective study to assess cervical scar satisfaction following conventional open thyroidectomy for thyroid cancer

BACKGROUND

Conventional open thyroidectomy (COT) remains a common method of thyroidectomy in many parts of the world for various reasons.

METHODS

In this prospective (cross-sectional) study, we evaluated the scar satisfaction among patients and surgeons following COT using the Patient and Observer Scar Assessment Scale (POSAS) and the Patient Scar Assessment Questionnaire (PSAQ).

RESULTS

A total of 116 patients were included. The median age of the patients was 44 years and the majority were women. The median scar length overall was 12.2 cm. On POSAS, the median score for surgeon 1 was 1 (range 1-5), for surgeon 2, it was 2 (range 1-6), and for the patient, it was 1 (range 1-6) suggesting good scar satisfaction. The patient's response in the PSAQ was also echoing similar outcomes with scar satisfaction.

CONCLUSIONS

Overall, both the patients and the surgeons seem to be satisfied with the overall scar appearance following COT despite the scar length.

Distress, illness perception and coping style among thyroid cancer patients after thyroidectomy: A cross-sectional study

PURPOSE

Thyroid cancer generally has a good prognosis, and thyroidectomy is the main treatment given to thyroid cancer patients. Almost every cancer patient experiences varying degrees of distress, which can reduce their quality of life. This study aims to explore the level of distress and its relationship with illness perception and coping style among Chinese thyroid cancer patients after thyroidectomy and to identify the influencing factors on distress.

METHODS

A cross-sectional study with convenience sampling method was conducted. Totally 184 thyroid cancer patients after thyroidectomy were recruited in a tertiary hospital in Southern China with the response rate being 94.4% . The participants were investigated by a self-designed demographic and disease-related questionnaire, the Distress Management, the Brief Illness Perception Questionnaire, and the Medical Coping Modes Questionnaire. Descriptive statistics, univariate analysis, and multivariate linear regression were applied for data analysis.

RESULTS

In total, 99 (53.8%) thyroid cancer patients after thyroidectomy scored 4 or higher on the DT. Illness perception, emotional problem, body image loss by surgical scars, and acceptance-resignation were the influencing factors of distress and could explain 67.6% of the variance of distress among thyroid cancer patients after thyroidectomy.

CONCLUSIONS

Healthcare professionals should not ignore the distress among thyroid cancer patients after thyroidectomy and should take effective measures to alleviate the distress of thyroid cancer patients after thyroidectomy by enhancing their accurate and positive illness perceptions, decreasing their emotional problems, alleviating their body image loss by surgical scars, and avoiding acceptance-resignation coping style.

Scarless Excision of Second Branchial Cleft Cyst via Retroauricular Hairline Incision

BACKGROUND

Second branchial cleft cyst (2nd BCC) is treated by complete excision. Conventional transcervical skin incision on the lesion may leave a prominent scar in the cosmetically sensitive area. The retroauricular hairline incision (RAHI) approach may maintain neurological, mobility, and cosmetic functions of the neck and face after excision. This study evaluated the clinical outcomes and disease control of scarless surgery via RAHI in 57 consecutive patients with 2nd BCC.

METHODS

The patients received the prospective evaluation of postoperative neurological, subjective pain, swallowing, neck motion, and cosmetic functions. Postoperative complications, subjective satisfaction, and recurrence were also assessed in each patient.

RESULTS

Excision was performed in all cases without injury to the facial nerve or other neurological complications and conversion to other incisions or approaches with a median operation time of 44 min. Complications were minimal, without dysphagia, neurological deficits, or limited neck motion. Postoperative incision scars in the postauricular and hairline region were commonly invisible. Subjective satisfaction with the scar and facial deformity was high after surgery. No patients had a recurrence for a median follow-up of 66 months.

CONCLUSION

The RAHI approach for 2nd BCC has excellent cosmetic, functional, and disease control outcomes. This can be safely applied to the treatment of 2nd BCC.

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.

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.

Do we still need Crile or Hayes Martin approach for cervical lymphadenectomy? A retrospective study of 56 patients with minimal access neck dissection

The concept of neck dissection was introduced by Crile more than a century ago. Since then, multiple modifications have been adopted to ensure the preservation of vital structures. With the new era of minimal access surgery, the incorporation of laparoscopic, endoscopic, and robotic surgery is becoming the new normal. Over the years we have carried out neck dissections using minimal access incisions. Although there is no definitive answer about the average nodal yield required in selective or modified neck dissections, it has been reported that the average nodal yield of more than 18 is associated with better survival rate. In this publication we share the results of our three-year retrospective study of 56 patients who underwent minimal access neck dissection. We look at the nodal yield, assess operating duration, complications, outcome with a three-year follow up from a single unit. Our results demonstrate that minimal access neck dissection should be considered in head and neck lymphadenectomies.

Neck scar perception after neck dissection in HPV-associated oropharyngeal squamous cell carcinoma

IMPORTANCE

While there has been an increased understanding of the impact of visible neck scars in some patients with certain diseases, this has not yet been explored in the HPV+ OPSCC population.

OBJECTIVE

To understand patients' perception of their scar and the impact on their quality of life (QOL) at least 6 months after neck dissection (ND) for HPV+ oropharyngeal squamous cell carcinoma (OPSCC).

DESIGN, SETTING, AND PARTICIPANTS

In this retrospective case-control study, patients who underwent primary transoral robotic surgery (TORS) and ND for HPV+ OPSCC between 2016 and 2021 at a single tertiary care center were identified. Data analysis was performed in January 2022.

MAIN OUTCOMES AND MEASURES

Dermatology Life Quality Index was modified (mDLQI) to assess patients' perceptions of their scars. The primary outcome was the mean mDLQI survey score with higher scores corresponding to worse perceptions. Three questions adapted from the Self-Consciousness Scale (SCS) were also included to assess awareness of appearance. All questions were scaled on a 0-3 Likert Scale. Tweedie generalized linear model was used to understand the relationship between mDLQI score and patient- and procedure-specific factors (including the three SCS survey questions). An additional exploratory logistic regression was performed to understand the risk factors for clinically significant mDLQI score change.

RESULTS

A total of 67 patients (response rate 57 %) completed the survey with a mean mDLQI survey score of 0.84 (max 30). Although there was a statistically significant negative association between private insurance and mDLQI survey score (95 % Confidence Interval [CI]: -2.72 - -0.38), and a positive association between the SCS score and mDLQI survey score (95 % CI: 0.23-0.81) (p < 0.05), these variables were not found to be risk factors for a clinically significant difference in mDLQI on multivariable analysis.

CONCLUSION

The majority of patients felt their neck scars did not interfere with their daily lives. Patient perceptions of neck scars were consistent despite differing patient characteristics and treatment regimens.

Retrospective comparison of endoscopic transoral and bilateral areolar approaches for thyroglossal cyst resection: a single-centre experience

PURPOSE

Our study aimed to compare the efficacy, safety, and clinical effect of the transoral approach and the bilateral areolar approach (BAA) for endoscopic thyroglossal duct cyst (TGDC) resection.

METHODS

In total, 42 patients who received an endoscopic TGDC resection between January 2019 and May 2022 via a transoral (n = 22) or bilateral areolar (n = 20) approach by a single surgeon were retrospectively enrolled. We collected and compared the following data: patients' demographic data, complication events, operative time, bleeding volume, drainage volume, 6-h postoperative pain scores, length of hospitalisation, resected TGDC size, and cosmetic satisfaction.

RESULTS

There were no cases of conversion to a transcervical approach in the two groups. No significant differences were found between the two groups in terms of age, sex, body mass index, complication, bleeding volume, 6-h postoperative pain scores, and TGDC size (all p > 0.05). However, the operative time and patients' cosmetic satisfaction were higher in the transoral group than in the BAA group (all p < 0.05). In addition, the drainage volume and length of hospitalisation in the transoral group were less than those in the BAA group (all p < 0.05).

CONCLUSIONS

Both the transoral approach and BAA are safe and reliable; however, the transoral approach is more complex than the BAA and offers better cosmetic satisfaction. Doctors should choose the appropriate surgical procedure based on the patient's condition and preferences.

Quality of Life in Chinese Youth Following Open Thyroid Surgery: A Qualitative Study

BACKGROUND

Because of the increased incidence of thyroid cancer and good survival rates and with research into scarless techniques, it is increasingly important to understand the quality of life of thyroid cancer patients and identify areas for improvement. Therefore, it is necessary to explore the importance of neck appearance after thyroidectomy for thyroid cancer survivors in China.

OBJECTIVE

The purpose of this study was to investigate the effect of scarring after open thyroid surgery on the quality of life of young patients.

METHODS

A descriptive qualitative design was used. Data were collected using face-to-face semistructured interviews and analyzed using directed content analysis.

RESULTS

Five men and 19 women participated in the study. The following 3 broad themes and 9 subthemes emerged, which were (1) emotional functioning, including low self-esteem due to high visibility of scars, concerns and helplessness about scarring lesions, and feelings of isolation due to lack of support; (2) social functioning, including restricted choice of employment, avoidance of socializing with others, and reduced participation in social activities; and (3) information seeking, acceptance, and living with the scar, including bargaining, seeking professional help, and use of social media.

CONCLUSIONS

After open surgery for thyroid cancer, patients experience a variety of scarring features that affect their quality of life. Therefore, preoperative communication and long-term postoperative care should be emphasized in clinical practice and research.

IMPLICATIONS FOR PRACTICE

Understanding the experience of carrying scars after thyroid cancer surgery helps provide adequate information, expectation management, and informed decision-making.

The Attitudes of Patients Toward Orthopaedic Post-surgical Scars

Background Post-surgical scars (PSS) are an expected consequence of surgery. Several factors have previously been associated with PSS satisfaction including patient age and time elapsed post-operative. Little data are available regarding patient attitudes toward orthopaedic PSS. Knowledge of patient attitudes and the various associated factors may allow physicians to administer peri-operative care to mitigate the potential negative effects of PSS. Our study aims to investigate the attitudes of patients toward their PSS using quantitative scar assessment scales and to identify factors associated with PSS satisfaction. Methods We conducted a retrospective study with a follow-up. We included all patients with orthopaedic PSS on their upper or lower limbs between two and 18 weeks postoperative attending Cork University Hospital, Ireland, between February and August 2022. Patients completed an initial baseline questionnaire and then a follow-up questionnaire six months post-operative. The Patient and Observer Scar Assessment Scale (POSAS) evaluated PSS satisfaction. The European Quality of Life 5 Domain (EQ-5D), alongside several Likert scales, evaluated the patient's quality of life (QoL). Results In total, 91 patients were included. The mean POSAS score was 28.41 (95% CI, 25.85-30.97). Younger patient age (p=0.045) and decreased time passed post-operatively (p=0.002) were associated with poorer PSS satisfaction. Patients reporting their PSS appearing worse than expected were more likely to agree that their QoL had been adversely affected by it (p=0.001). Conclusion Most patients were satisfied with their orthopaedic PSS. This study identified several factors associated with poor PSS satisfaction. Our finding, which associated patient scar expectations and QoL, is novel and has not been previously examined. Accordingly, peri-operative interventions, including scar expectation management, may be implemented to mitigate scar-related QoL impact.

Quantitative evaluation of pediatric umbilical loop stomas: 2 decades of experience from a single institution

PURPOSE

Since pediatric stomas are often temporary, their creation, management, and closure should be simple, with minimal complications and excellent cosmetic results. We began employing umbilical stomas in 2000. This study aimed to characterize the ingenuity and utility of umbilical stomas and provide a quantitative evaluation of their cosmetic outcomes.

METHODS

We examined cases of stoma construction and closure surgery performed in our department from January 2000 to December 2022. The umbilical and non-umbilical stoma groups included 54 and 42 cases, respectively, and the findings for both groups were compared and analyzed.

RESULTS

The two groups showed no significant differences in the incidence of complications. The Manchester Scar Scale score for the umbilical stoma group (8.42 ± 1.85) was significantly better than that for the non-umbilical stoma group (16.31 ± 2.96; P < 0.01). Likewise, in Patient and Observer Scar Assessment Scale assessments, the umbilical stoma group showed significantly better scores in both the observer scale (9.48 ± 2.50 vs. 21.78 ± 7.26; P < 0.01) and the patient scale (10.5 ± 1.39 vs. 22.40 ± 7.35; P < 0.01).

CONCLUSIONS

Umbilical stomas are easy to manage and yield an inconspicuous closure incision with excellent cosmetic outcomes. Although patient selection is important, pediatric umbilical stomas are a valuable option that can be actively employed.

Evaluation of public's perception of scar cosmesis after thyroidectomy: results of a survey of Turkish versus South Korean individuals

Purpose

Visible scars on the neck caused by thyroid surgery give rise to significant aesthetic, functional, and psychosocial problems. The objective of this study is to comparatively investigate the public perception of neck scar cosmesis in Turkish and South Korean populations.

Methods

This survey was prepared to collect participants' demographic and socioeconomic data and determine their perception of scar cosmesis on the neck and consisted of 15 questions. One thousand thirty-nine individuals who did not undergo thyroid surgery completed the survey. The P-values of <0.05 were deemed to indicate statistical significance.

Results

There were 1,039 respondents, of whom 525 (50.5%) were Turkish and 514 (49.5%) were South Korean. South Korean respondents stated that they would be significantly more uncomfortable with the thought of having a scar due to thyroid surgery, compared to the Turkish respondents (P < 0.001). The South Korean respondents stated that they would be significantly more concerned about the scar's length, thickness, and darkening color, compared to the Turkish respondents (P < 0.001 for all cases).

Conclusion

Patients' expectations, which are affected by various sociodemographic factors and cultural characteristics, are as important as the medical condition when deciding on the type of thyroid surgery. The study findings clearly indicated that the South Korean population would be significantly more uncomfortable with having a scar on the neck, compared to the Turkish population. Therefore, in selected cases, a scarless thyroidectomy approach, such as transoral endoscopic thyroidectomy, vestibular approach may be preferable for societies like South Korea.

Is transoral endoscopic thyroidectomy safe for total thyroidectomy compared to open thyroidectomy? A propensity-score matched cohort study with papillary thyroid carcinoma

BACKGROUND

Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) has become increasingly popular in the treatment of papillary thyroid cancer (PTC). This study aimed to describe the safety and feasibility of total thyroidectomy between the TOETVA and open thyroidectomy (OT) approaches for the treatment of patients with PTC.

METHODS

We retrospectively reviewed 780 consecutive patients suffering from PTC that had undergone total thyroidectomy using TOETVA (n = 107) and OT (n = 673) between April 2016 and December 2021 at our institute. Afterward, a total of 101 matched patients' surgical outcomes were compared using propensity score matching (PSM) analysis.

RESULTS

Before PSM, the patients in the TOETVA group were younger (p < 0.001), had a lower body mass index (p < 0.001) and a greater female population (p < 0.001). After PSM, the TOETVA group was associated with significantly longer operative time (p < 0.001), greater blood loss (p < 0.001), total drainage amount (p < 0.001), higher C-reaction protein level (p < 0.001), better cosmetic satisfaction (p < 0.001) and quality of life (p < 0.001) and lower scar self-consciousness (p < 0.001). There was no statistical difference between the groups in the rate of parathyroid autotransplantation and bilateral lymph node dissection, the positivity of lymph node metastasis, number of dissected lymph nodes and positive lymph nodes, multifocality, postoperative level of blood calcium and parathyroid hormone (PTH), rate of PTH < 15 ng/mL, visual analog scale score, duration of hospital stay, complications, mean thyroid stimulating hormone (TSH)-stimulated Tg level before radioactive iodine, mean Tg level without TSH stimulation, and the proportion of serum Tg level of <1.

CONCLUSION

TOETVA is a safe and feasible technique for better cosmetic effects and similar surgical outcomes compared to conventional open surgery for the studied patients that required total thyroidectomy.

First Experience of Single-Port Robotic Areolar Approach Thyroidectomy

OBJECTIVES

Numerous minimally invasive thyroidectomy techniques have been developed and are actively utilized in hospitals around the globe. Herein, we describe a recently developed minimally invasive thyroidectomy technique that employs the da Vinci SP, and we present the preliminary clinical outcomes of single-port robotic areolar thyroidectomy (SPRA).

METHODS

A 3-cm semi-circular incision on the right areola and a small 8-mm incision on the left areola were created. Using hydro-dissection and an advanced bipolar device, a subcutaneous skin flap was created, extending from the areola to the thyroid cartilage. The da Vinci SP was then inserted through the incision in the right areola. Between December 2022 and March 2023, 21 SPRA procedures were conducted. Patients' medical records and surgical videos were subsequently reviewed.

RESULTS

Lobectomy was performed in 17 patients, isthmectomy in 2 patients, and total thyroidectomy in 2 patients. The mean flap time was 14.9±4.2 minutes and the console time was 62.4±17.1 minutes. The mean tumor size was 0.89± 0.65 cm and the number of retrieved lymph nodes was 3.94±3.98 (range, 0-12). There were no observed instances of vocal cord palsy or hypoparathyroidism.

CONCLUSION

We successfully developed and performed the novel SPRA for the first time worldwide. Unlike other robotic surgery.

METHODS

SPRA is less invasive and leaves no visible scars. This technique employs a sophisticated single-port robotic device. However, to assess the efficacy of this method, we need to analyze more cases and conduct comparative studies in the near future.

Modern Surgical Techniques of Thyroidectomy and Advances in the Prevention and Treatment of Perioperative Complications

Thyroid cancer is the most common cancer of the endocrine system, and, in recent years, there has been a phenomenon of overdiagnosis followed by subsequent overtreatment. This results in an increasing number of thyroidectomy complications being faced in clinical practice. In this paper, we present the current state of knowledge and the latest findings in the fields of modern surgical techniques, thermal ablation, the identification and assessment of parathyroid function, recurrent laryngeal nerve monitoring and treatment and perioperative bleeding. We reviewed 485 papers, from which we selected 125 papers that are the most relevant. The main merit of this article is its comprehensive view of the subject under discussion-both general, concerning the selection of the appropriate method of surgery, and particular, concerning the selection of the appropriate method of prevention or treatment of selected perioperative complications.

The quality of life after trans oral video-assisted thyroidectomy and cervical thyroidectomy: a systematic review and meta-analysis

Trans oral video-assisted thyroidectomy (TOVAT) is increasingly performed for cosmetic reasons. The quality of life after thyroidectomy is important for decision-making. This is the first meta-analysis to compare the quality of life among conventional transcervical thyroidectomies. This meta-analysis aimed to assess the same in the current literature. The authors systematically searched PubMed, Google Scholar, and EBSCO for relevant articles from the first published to December 4, 2022. The keywords endoscopic transoral via vestibular thyroidectomy, transcervical thyroidectomy, conventional thyroidectomy, scarless thyroidectomy, and quality of life were used. Out of the 482 studies retrieved, 27 full texts were reviewed, and only six fulfilled the inclusion and exclusion criteria. Patients with transoral thyroidectomy showed better quality of life that their counterparts who underwent transcervical thyroidectomy at 4-6 weeks following surgery, odd ratio, 2.26, 95% CI, 2.02-2.5, P-value <0.001. Substantial heterogeneity was observed, I² for heterogeneity, 100%. The quality of life was better among patients who underwent the trans oral video-assisted thyroidectomy (TOVAT) compared to their counterparts with the conventional cervical approach (surgical questionnaire). All the components of the SF-36 quality of life questionnaire were better among TOVAT compared to the conventional approach except for social and general health components, which were equal between the two arms. Further multi-center studies with larger samples and controlling for pain and the surgical curve are needed.

Facial scars resulting from a transbuccal approach during osteosynthesis of a sagittal split osteotomy: A retrospective study

The purpose of the current study was to assess the quality of facial linear scars. The Stony Brook Scar Evaluation Scale (SBSES) was developed and validated as a tool to assess postoperative scars. Postoperative facial scars were rated using high-quality macrophotographs and SBSES by three independent raters at baseline and three months thereafter. Percentage agreement (PA) and intraclass correlation coefficient (ICC) were used to measure interrater and intrarater reliability. Scar outcomes ranging from 0 (worst) to 5 (best) were evaluated against age and gender. One-hundred-sixty-six patients with a mean age of 30.6 years (range of 17-59) were included in this study. Forty-four were male (26.5%), and 122 were female (73.5%). Mean total SBSES scores were 4.63 (range of 4.56-4.76) at baseline and 4.60 (range of 4.54-4.72) at three months. As patient's age increased, mean total SBSES scores also decreased significantly (r = -0.216, p = 0.005). Gender did not significantly affect raters' perception of scar cosmesis (p = 0.847). Interrater reliability showed an ICC of 0.675 (95% CI, 0.609-0.731) and a PA of 65.4% at baseline, and an ICC of 0.655 (95% CI, 0.585-0.715) and a PA of 64.2% at three months. Intrarater reliability found ICCs ranging from 0.988 to 0.990 and a PA of 96.8% with 3 separate raters. Within the limitations of the study it seems that the transbuccal approach during osteosynthesis of a sagittal split osteotomy seems still to be acceptable when the patient gives his or her informed consent and advanced instruments like an angled screwdriver are not available.

Evaluation of Preference and Utility Measures for Transoral Thyroidectomy

BACKGROUND

Traditional, trans-cervical thyroidectomy results in the presence of a neck scar, which has been shown to correlate with lower quality of life and lower patient satisfaction. Transoral thyroid surgery (TOTS) has been utilized as an alternative approach to avoid a cutaneous incision and scar by accessing the neck and thyroid through the oral cavity. This study was designed to evaluate patient preference through health-state utility scores for TOTS as compared to conventional trans-cervical thyroidectomy.

METHODS

In this cross-sectional study, patient preferences were elicited for TOTS and trans-cervical thyroidectomy with the use of an online survey. Respondents were asked to consider 4 hypothetical health scenarios involving thyroid surgery with varying approaches. Health-state utility scores were elicited using visual analog scale and standard gamble exercises.

RESULTS

Overall, 516 respondents completed the survey, of whom 261 (50.6%) were included for analysis, with a mean age of 41.5 years (SD 14.9 years), including 171 (65.5%) females. Health utility scores were similar for TOTS and conventional transcervical techniques. Statistically significant differences in the standard gamble utility score were noted for gender and ethnicity across all scenarios. Comparisons of visual analog score utilities were not statistically significant based on respondent demographics.

CONCLUSION

Preferences for TOTS and trans-cervical thyroidectomy did not significantly differ in the current study. Females and white ethnicity indicated stronger preference for a TOTs approach compared to males and other ethnicities, respectively. Some literature suggests certain types of patients who might prefer minimally invasive thyroidectomy more so than other patients-in keeping with the current findings of this study.

Unilateral axilo-breast approach (UABA) with gas insufflation versus open conventional hemithyroidectomy: A prospective comparative study

BACKGROUND

The objective of this study was to compare with the conventional open approach, the surgical and aesthetic results of endoscopic thyroidectomy via unilateral axillo-breast approach (UABA) with gas insufflation in patients with a unilateral thyroid nodule.

METHODS

Between August 2017 and August 2020, a prospective comparative cohort study was carried out in patients proposed for hemithyroidectomy. The patients were assigned to one type of approach (Open or Endoscopic) in a successive manner. Surgical results and aesthetic satisfaction at hospital discharge and during the 12-month follow-up were evaluated and compared between both groups.

RESULTS

A total of 200 patients were included in the study: 100 for the Open approach and 100 for the Endoscopic. The baseline patient characteristics were similar between both groups. Total operative time was longer in the Endoscopic approach, due to the time required for subcutaneous dissection (the hemithyroidectomy time was similar in both groups). There was no significant difference in the frequency of major complications. The length of hospital stay was longer (for 1 day) in the Endoscopic group. The aesthetic satisfaction of the patients was significantly higher in the Endoscopic than in the Open group (p < 0.001), at hospital discharge and at 12-month follow-up.

CONCLUSION

UABA with gas insufflation for hemithyroidectomy represents a safe and effective therapeutic option for the treatment of unilateral benign thyroid pathologies.

Quality of Life Following Robotic Transaxillary Versus Conventional Hemithyroidectomy: A Comparative Analysis

Background: Robotic technology has proven safe and effective for thyroidectomy procedures. Few studies have addressed the quality-of-life outcomes of robotic thyroidectomy compared with conventional thyroidectomy. Materials and Methods: The database of a tertiary medical center was retrospectively reviewed for all patients with thyroid disease who had undergone robotic hemithyroidectomy in 2012-2020. All patients treated by transaxillary robotic surgery and a similar number of randomly selected patients treated by conventional cervical surgery completed a standardized self-administered thyroid disease-specific quality-of-life (QOL) questionnaire (ThyPRO). Clinical data were derived from the medical files. The results were compared using mean comparison tests and multivariate logistic regression models. Results: The cohort consisted of 131 patients: 63 after robotic thyroidectomy and 68 after conventional thyroidectomy. The mean age was 38.87 ± 14.11 and 58.85 ± 14.1 years, respectively (P < .0001). The robotic hemithyroidectomy group reported better QOL outcomes in physical and mental health parameters, including decreased anxiety, depression, lower sex life impairment, and cognitive impairment scores (P < .0001). Furthermore, after adjusting for age, gender, malignancy status, and surgical approach, we found that patients undergoing robotic hemithyroidectomy had a lower probability of experiencing depressive symptoms than the conventional hemithyroidectomy group (odds ratio = 0.31; 95% confidence interval, 0.11-0.88). Of interest, no significant difference in cosmetic outcomes was found. Conclusions: Patients who underwent robotic thyroidectomy report better postoperative QOL after surgery than patients operated by the conventional approach in terms of anxiety, depression, cognitive and sex-life scores.

Comparison of the endoscopic thyroidectomy via areola approach and open thyroidectomy: A propensity score matched cohort study of 302 patients in the treatment of papillary thyroid non-microcarcinoma

Background

The endoscopic thyroidectomy via areola approach (ETAA) is widely used in patients with benign thyroid tumors and papillary thyroid microcarcinoma (PTMC). Its safety and complication rates are reported to be similar to open thyroidectomy (OT). This study aimed to evaluate the safety and feasibility of ETAA, compared with OT, in patients with papillary thyroid non-microcarcinoma (PTNMC).

Methods

We retrospectively reviewed all patients with PTNMC who underwent ETAA or OT in our hospital from January 2017 to December 2021. A total of 302 patients were matched at a ratio of 1:1 by the propensity score matching (PSM) analysis and surgical outcomes. Safety and feasibility were analyzed between two groups.

Results

Before PSM, patients in the ETAA group were younger (p < 0.001) and had a larger proportion of female patients (p < 0.001) with a lower BMI (p < 0.001) compared with the OT group. The ETAA group also had a higher proportion of unilateral thyroidectomy (p = 0.002). PSM was used to create a highly comparable control group. After PSM, the ETAA group had a longer operative time (p < 0.001), larger blood loss (p = 0.046) and total drainage amount (p = 0.035), with higher C-reactive protein (p = 0.023) and better cosmetic outcomes (p < 0.001). There were no significant differences in the following clinicopathologic characteristics: number of dissected positive lymph nodes, rate of recurrent laryngeal nerve signal weakened, parathyroid autotransplantation, postoperative pain, hospital stay, complications, and oncologic completeness. There was no patient converted to OT in the ETAA group and two patients suffered from persistence/recurrence in the follow-up.

Conclusion

ETAA is a safe and feasible surgical approach for patients with PTNMC.

Transoral thyroid surgery vestibular approach

Objectives

Transoral thyroid surgery vestibular approach (TOETVA) is a novel and feasible surgical technique that allows for cervical surgery without visible incisions. TOETVA represents a new frontier in endocrine surgery since aesthetic results play a more and more decisive role in elective surgery. However, acceptance is different around the world with widespread prevalence in Asian countries and some high-volume centres in the US. While inclusion criteria for TOETVA are limited regarding size and volume a combination with other extracervical techniques like the retroauricular endoscopic cephalic access thyroid surgery (EndoCATS) approach or transaxillary access is an option.

Methods

TOETVA is carried out through a three-port technique placed at the oral vestibule. Originally one 10-mm port for a 30° endoscope and two additional 5-mm ports for dissecting and coagulating instruments are used. Alternatively, one 5-mm and one or two 3 mm ports can be used. CO2 insufflation pressure is set at 6 mmHg. An additional device to optimize gas outflow for optimum view might be helpful. An anterior cervical subplatysmal space is created by hydrodissection from the oral vestibule to the sternal notch, laterally to the sternocleidomastoid muscle. Conventional endoscopic instruments are used. Combination of TOETVA with a modified retroauricular access includes insertion of a 10-12 mm trocar placed subcutaneously via a skin incision on the scalp, behind the ear by blunt dissection.

Results

Since Anuwong published the first case series of 60 patients who underwent scarless thyroidectomy via the lower vestibule of the mouth with excellent results in 2016 almost 1,000 cases are reported in literature to date with comparable results especially regarding traditional complications. In contrast to other extracervical approaches, areolar or axillary for example, the transoral access route is short and the dissection planes are rather like transcervical surgery. Surgical indications and contraindications have been modified since its first description and are partly institution specific to date. To amend indications combination with other extracervical techniques is an option. In addition, patients must carefully be selected for and surgeons` candidacy is of utmost importance in transoral surgery.

Conclusions

Transoral surgery will likely continue to gain attraction as surgeons become more experienced with the technique. With increased operative use and surgeon experience the gap in conventional outcomes between transoral surgery and the transcervical approach will narrow, with both operative time and the incidence of specific complications diminishing. Experience in thyroid and endoscopic surgery is required to achieve excellent results with low complication rates. However, the new transoral technique is related to novel complications that must be evaluated.

The Patient Experience of Thyroid Cancer

The 3 phases of thyroid cancer care are discussed: diagnosis, management, and survivorship. Drivers of quality of life (QOL) in each phase are described, and suggestions are made for mitigating the risk of poor QOL. Active surveillance is another emerging management strategy that has the potential to improve QOL by eliminating upfront surgical morbidity but will need to be studied prospectively.

Thyroidectomy via unilateral axillo-breast approach (UABA) with gas insufflation: prospective multicentre European study

Background

Extracervical approaches for thyroidectomy are seldom explored in the western population. The objective of this study was to evaluate the outcomes of hemithyroidectomy via endoscopic unilateral axillo-breast approach (UABA) with gas insufflation.

Method

Consecutive patients undergoing UABA hemithyroidectomy for symptomatic benign or cytologically indeterminate nodules (Bethesda III lesions) of less than 5 cm from July 2015 to December 2020 at three European institutions were included. Patients were excluded if presenting with a BMI more than 25 kg/m², had previous neck surgery and/or radiation, had bilateral thyroid lesions, retrosternal goitre, Hashimoto thyroiditis or Graves’ disease. Follow-up was carried out at 2 weeks, 3 months and 1 year. Outcomes of interest were surgical (including operating time, mean duration of hospital stay and complications) and self-assessed cosmetic outcomes.

Results

Out of 984 patients treated with hemithyroidectomy during the study interval, 253 were selected, including 214 women and 39 men. Patients’ mean age was of 46.6 years with a mean BMI of 22.57. Mean operating time was 72.9 minutes. A transient recurrent laryngeal nerve injury was reported in 3.6 per cent of the patients, but none was persistent. Transient pectoral/cervical hypoesthesia was noted in 24.1 per cent of patients, with no permanent hypoesthesia. Skin burns and subcutaneous hematoma developed in 2.4 per cent and 2 per cent of patients but resolved within the third month after surgery. There was no tracheal/oesophageal perforation, conversion to open surgery or reoperation. The final pathology revealed 241 benign nodules, nine underlying papillary thyroid carcinomas, and three cases of follicular carcinoma. Hospital discharge was achieved on the first in 68.8 per cent of the patients and on the second postoperative day in 31.2 per cent of the cases. All patients were satisfied with the cosmetic aspect.

Conclusion

In selected patients, UABA with gas insufflation for hemithyroidectomy could be performed for the treatment of unilateral thyroid pathologies.

Early Postoperative Polydeoxyribonucleotide Injections Prevent Hypertrophic Scarring after Thyroidectomy: A Randomized Controlled Trial

OBJECTIVE

Polydeoxyribonucleotide (PDRN) is known to enhance wound healing, but there has been no clinical trial investigating the effect of PDRN on scar prevention in surgical wounds. This study aimed to evaluate the efficacy of PDRN administration in preventing postoperative scars.

APPROACH

In this randomized controlled trial (NCT05149118), 44 patients who underwent open thyroidectomy were randomly assigned to the PDRN treatment or untreated control group. Only patients in the treatment group received two consecutive injections of PDRN one and two days after surgery. The modified Vancouver Scar Scale (mVSS), patients' subjective symptoms, erythema index (EI), melanin index (MI), and scar height were assessed three months after surgery.

RESULTS

Patients in the treatment group had lower mVSS scores (1.619 ± 1.244 vs. 2.500 ± 1.540, respectively; P = 0.059) and a significantly lower vascularity subscore (0.476 ± 0.512 vs. 0.900 ± 0.447, respectively; P = 0.010) than those in the control group at the 3-month follow-up. Compared with the control group, the level of subjective symptoms, EI, and scar height were all significantly lowered in the PDRN injection group. No specific side effects related to PDRN injection were observed.

INNOVATION

This is the first clinical study which demonstrated that PDRN injections rapidly decreased postsurgical wound erythema and as a result, significantly reduced both excessive scar formation and accompanying symptoms.

CONCLUSION

Early postoperative injection of PDRN is an effective and safe treatment to prevent hypertrophic scars and improve scar outcomes.

The Effectiveness and Quality of Life Outcomes by Transoral Endoscopic Vestibular Thyroidectomy Using Intraoperative Indocyanin Green Fluorescence Imaging and Neuromonitoring—A Cohort Study

Background: Transoral endoscopic vestibular thyroidectomy (TOEVT), a variant of natural orifice transluminal endoscopic surgery, offers a scar-less thyroid to young females. However, few studies have compared the effectiveness and quality of life (QoL) outcomes of the TOEVT with open thyroidectomy (OT). This is the first study in the Middle East and North Africa region that compares the effectiveness, safety profile and QoL outcomes between TOEVT with OT. Methods: We reviewed the medical records of consecutive patients with TOETV and OT at Zulekha Hospital Sharjah and Dubai United Arab Emirates, between 1 January 2019 and 1 April 2021. The data for demographics, type of surgery, operative time, blood loss, post-operative nodule size, hospital stay and post-operative complications were analyzed. We used an SF-36 questionnaire pre- and postoperatively for the assessment of QoL in both groups. Findings: Out of a total of 41 OT and 32 TOEVT procedures, 59 patients (31 TOEVT and 28 OT) fulfilled the inclusion criteria. There were 45 women and 14 men with an average age of 41 years. The mean operating time was 126 min in TOEVT and 96 min in OT (p = 0.000). The mean thyroid size was 5.55 cm in TOEVT and 8.76 cm in OT (p = 0.000). Lastly, the mean intraoperative blood loss was 39 cc and 95.7 cc in TOEVT and OT, respectively (p = 0.001). There was one temporary hypocalcemia and seroma in TOEVT, four cases of temporary hypocalcemia and one with minor bleeding in OT. The post-operative QoL significantly improved in all patients. However, the QoL improved more significantly in the TOEVT group for bodily pain, vitality, role emotions and cosmetic concerns (p = 0.000). Conclusion: The safety profile and effectiveness of the TOEVT is comparable to the OT procedure. However, TOEVT has an additional advantage of being scarless and offers a better QoL.

Time Heals Most Wounds - Perceptions of Thyroidectomy Scars in Patients With Thyroid Cancer

BACKGROUND

Patients understandably have concerns about thyroidectomy scars. This study aimed to characterize patients' perceptions of their thyroidectomy scar before and up to 1-y after surgery.

METHODS

Patients with papillary thyroid cancer (n = 83) completed semi-structured interviews before and at 2-wks, 6-Wk, 6-mo, and 1-y post-thyroidectomy. Interviews probed about scar concerns and appearance. Content analysis was used to identify themes.

RESULTS

The majority of participants did not express concerns about scar appearance. When expressed, preoperative concerns often stemmed from previous surgery experiences or unease with neck incisions. Postoperatively, concerns about scar appearance decreased over time throughout the healing period with most patients being satisfied with their scar appearance by 6-mo after surgery.

CONCLUSIONS

Patients with papillary thyroid cancer express few concerns about scar thyroidectomy appearance. Surgeons can reassure patients who have preoperative concerns that most patients are satisfied with their scar appearance by 6-mo after surgery.

Gasless endoscopic thyroidectomy via modified areola approach with a simple flap-lifting technique

OBJECTIVE

Studies have shown that carbon dioxide (CO2) insufflation during endoscopic thyroidectomy is associated with many risks. Recently, we have designed a simple lifting tool using Kirschner wire. We aimed to use this tool for flap-lifting in modified areola approach endoscopic thyroidectomy and compare it with conventional CO2 insufflation.

METHODS

In a prospective study, patients who underwent endoscopic thyroidectomy via modified areola approach were randomly assigned into gasless (n = 20) or CO2 groups (n = 22). Pre-operative variables included age, gender, tumor diameter, and clinical diagnosis. Intra-operative hemodynamic monitoring included mean arterial pressure, heart rate, pulse oximetry, end-tidal carbon dioxide (ET-CO2) and arterial pH. Other intra-operative details included total operative time, operative blood loss, conversion from endoscopic surgery to open surgery, intra-operative events, and endoscope video score. Postoperatively, the hospital stay, drainage volume, and complications were recoded.

RESULTS

Patient characteristics were not different between the two groups. During the operation, ET-CO2 levels were significantly higher in the CO2 group (P < 0.05), whereas arterial pH levels were significantly lower (P < 0.05). The CO2 group had longer operation time and higher endoscope clarity VAS score than gasless group. Hospital stay, drainage volume, and postoperative complications did not differ significantly between the two groups (P > 0.05).

CONCLUSIONS

The gasless endoscopic thyroidectomy we performed via our Kirschner wire hook was safe, feasible, and yielded good results.

The steps and key points of thyroid surgery with lateral cervical incision

The thyroid surgery with lateral cervical incision uses the sternocleidomastoid intermuscular approach through the gap between band muscles and carotid sheath to reach the surgical field. The recurrent laryngeal nerve and upper and lower parathyroid glands are first identified, the upper pole vessels are severed; then the Berry ligament is separated; the isthmus is severed, and the thyroid gland is finally removed. This approach can avoid the trauma of the skin and muscle tissue in the anterior neck region, to relieve the pressure on the neck and swallowing stretch feeling for patients after surgery. The surgical modality is effective and less time-consuming. This article gives a detailed introduction to the standardized procedures and some key points of thyroid surgery with lateral cervical incision.

Transoral endoscopic vestibular approach Sistrunk procedure: First reported case series

BACKGROUND

Standard of care for management of thyroglossal duct cysts (TGDCs) is a Sistrunk procedure performed through a transcervical incision. We describe the first series of Sistrunk procedures performed through a transoral endoscopic vestibular approach, eliminating a visible external scar.

METHODS

The transoral endoscopic vestibular approach to the Sistrunk (TEVAS) was performed in patients with TGDCs meeting inclusion criteria who desired a scarless approach.

RESULTS

Six patients (five females and one male) underwent TEVAS, with a mean age of 38 years (range 16-56 years) and a mean TGDC size of 1.8 cm (range 1.1-2.4 cm). Mean operative time was approximately 5 h (range 2-8 h). There were no surgical complications or recurrences.

CONCLUSIONS

For appropriately selected patients, the TEVAS is an alternative to open neck surgery that provides improved cosmesis while maintaining successful resection outcomes. More data on outcomes including complications and recurrences are needed as additional case information is collected.

Factors Influencing Hypertrophic Scarring after Thyroidectomy

OBJECTIVE

To identify the risk factors of hypertrophic scarring (HS) after thyroidectomy and construct a risk prediction model.

METHODS

From November 2018 to March 2019, the clinical data of patients undergoing thyroidectomy were collected for retrospective analysis. According to the occurrence of HS, the patients were divided into an HS group and a non-HS group. Univariate analysis and binary logistic regression analysis were conducted to explore the independent risk factors for HS. Receiver operating characteristic analysis was also carried out.

RESULTS

In this sample, 121 of 385 patients developed HS, an incidence of 31.4%. Univariate analysis showed significant differences in sex, age, postoperative infection, history of abnormal wound healing, history of pathologic scar, family history of pathologic scar, and scar prevention measures between the two groups (P < .05). Binary logistic regression analysis indicated that age 45 years or younger (odds ratio [OR], 1.815), history of abnormal wound healing (OR, 4.247), history of pathologic scarring (OR, 9.840), family history of pathologic scarring (OR, 5.708), and absence of preventive scar measures (OR, 5.566) were independent factors for HS after thyroidectomy. The area under the receiver operating characteristic curve was 0.837. When the optimal diagnostic cutoff value was 0.206, the sensitivity was 0.661, and the specificity was 0.932.

CONCLUSIONS

The development of HS after thyroidectomy is related to many factors, and the proposed risk prediction model based on the combined risk factors shows a good predictive value for postoperative HS. When researchers consider the prevention and treatment of scarring in patients at risk, the incidence of HS in different populations can provide theoretical support for clinical decision-making.

Current therapeutic options for low-risk papillary thyroid carcinoma: A scoping evidence review

Most cases of thyroid carcinoma are classified as low risk. These lesions have been treated with open surgery, remote access thyroidectomy, active surveillance, and percutaneous ablation. However, there is lack of consensus and clear indications for a specific treatment selection. The objective of this study is to review the literature regarding the indications for management selection for low-risk carcinomas. Systematic review exploring inclusion and exclusion criteria used to select patients with low-risk carcinomas for treatment approaches. The search found 69 studies. The inclusion criteria most reported were nodule diameter and histopathological confirmation of the tumor type. The most common exclusions were lymph node metastasis and extra-thyroidal extension. There was significant heterogeneity among inclusion and exclusion criteria according to the analyzed therapeutic approach. Alternative therapeutic approaches in low-risk carcinomas can be cautiously considered. Open thyroidectomy remains the standard treatment against which all other approaches must be compared.

How we do it: 'tonsil swabs please' - an alternative use in open neck surgery

BACKGROUND

Thyroid and parathyroid surgery often involves the use of heated instruments for dissection. Whilst these are beneficial, accidental thermal damage to the exposed skin edges can occur, resulting in an unsatisfactory cosmetic outcome. Tonsil swabs can be used in head and neck surgery intra-operatively to control bleeding. This paper describes an alternative use for them in protecting wound edges during the procedure.

METHOD

Damp tonsil swabs are sutured onto the wound edges after the initial skin incision. They remain present for the duration of the surgery and are removed at the time of skin closure.

RESULTS

The tonsil swabs provide protection and help avoid accidental injury to the skin. No complications with this technique have been experienced.

CONCLUSION

This paper describes a simple, effective and practical technique for protecting the skin during neck procedures using resources readily available in a standard ENT operating theatre.

Safety and Efficacy of Radiofrequency Ablation of Thyroid Nodules-Expanding Treatment Options in the United States

CONTEXT

Radiofrequency ablation (RFA) has only recently gained popularity in the United States for treatment of thyroid nodules (TNs), with a limited number of patients having undergone the procedure in this country.

OBJECTIVE

To evaluate the safety and efficacy of RFA of TNs performed in an outpatient setting in the United States.

METHODS

This is a retrospective, single-center study of 53 patients who underwent RFA of 58 TNs between November 2018 and January 2021. The reduction in volume of nodule, cosmetic and symptomatic improvement, effect on thyroid function, and complications following RFA were assessed.

RESULTS

Eleven out of 53 patients were excluded from the analysis. A total of 47 benign TNs (23 nonfunctioning thyroid nodules [NFTNs] and 24 autonomously functioning thyroid nodules [AFTNs]), were assessed after RFA. The median reduction in volume was 70.8% after a median follow-up period of 109 days, with symptomatic and cosmetic improvement (P < 0.0001). Compared with larger nodules, smaller nodules had greater volume reduction (P = 0.0266). RFA improved thyrotropin (TSH) in AFTNs (P value = 0.0015) and did not affect TSH in NFTNs (P value = 0.23). There were no major complications; however, 1 patient had self-limited local bleeding and another had transient voice change that recovered in 6 months.

CONCLUSION

RFA is a safe and efficacious treatment for symptomatic NFTNs and AFTNs in our population and is especially effective for smaller nodules. RFA should be considered an alternative for TNs in patients who cannot or do not want to undergo surgery.

Robotic and Endoscopic Approaches to Head and Neck Surgery

Technological developments have disrupted the practice of medicine throughout history. Endoscopic and robotic techniques in head and neck surgery have emerged over the past half-century and have been incrementally adapted to expanding indications within otolaryngology. Robotic and endoscopic surgery have an established role in treatment of oropharyngeal and laryngeal cancers, reducing surgical morbidity and improving survival relative to traditional open approaches. Surgical treatment of human papillomavirus-mediated oropharyngeal cancer via transoral robotic surgery offers equivalent oncologic and functional outcomes relative to radiotherapy. Newer iterations of single-port robotic systems continue to expand the scope of robotics in head and neck surgery.

Trans Oral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) in Brazil: Safety and complications during learning curve

Objective

The aim of this study was to address the first cases of TOETVA done in Brazil, by TOETVA-Bra study group, regarding safety and complications.

Methods

Series of the first 93 TOETVAs cases in Brazil. All authors except LPK, AJG JOR and RPT received TOETVA training including cadaveric hands-on in Thailand or United States (Johns Hopkins Medicine) during 2017. After they came back to Brazil and started doing their first TOETVA cases in the cities of Rio de Janeiro, Sao Paulo and Chapecó they agreed to collaborate and gather data using an online spreadsheet. All patients were submitted to the technique described by Anuwong.

Results

A total of 93 patients underwent TOETVA. Most patients (58.1%) were submitted to total thyroidectomy and 59.1% had benign disease. Two patients (2.2%) needed conversion to open surgery. Five patients (9.3%) developed transient hypoparathyroidism and there were 3 (2.0%) temporary recurrent laryngeal nerve palsy. There was one (0.7%) permanent unilateral palsy. Twenty patients had some sort of complication, 16.1% were minor and 5.4% were major. A total of 73 patients (78.5%) had an uneventful recovery.

Conclusion

The technique is reproducible with a low complication rate. While further studies are needed to confirm equivalency, early efforts suggest that TOETVA is not inferior to traditional open thyroidectomy in appropriately selected patients.

Public perceptions of transoral endocrine surgery and their influence on choice of operative approach

BACKGROUND

Transoral Endocrine Surgery (TES) represents an alternative to the open approach with no visible scar. Studies have shown TES has a safety profile similar to the open approach, but adoption has been limited. Public perception and preference for TES are factors associated with adoption that have not been explored. Here we aim to understand the perception of TES by the public and factors which influence decision making.

MATERIALS AND METHODS

A 38-question survey was designed to assess factors which influence willingness to pursue TES. The survey was distributed utilizing Amazon Mechanical Turk (MTurk), a crowdsourcing marketplace in which individuals perform tasks virtually based on interest. Descriptive analyses, Pearson chi-squared tests, Student's t-tests, and multivariate logistic regression were performed to evaluate theoretical decision to pursue TES.

RESULTS

Respondents (n = 795) were 47% female, 78% white, 70% held a college degree or higher, and had a mean age of 37. The majority (69%) preferred a mouth incision over a neck incision. Respondents were willing to pursue TES for a theoretical cancer despite increased cost (52%) and longer operative time (70%). Respondents top two most important surgical factors were safety and experience.

CONCLUSIONS

Our data suggest the general public is willing to pursue TES and factors thought to be barriers to choosing TES may not deter the public. An informed discussion with appropriately-selected patients should be had between the patient and surgeon regarding specific surgical and postoperative differences including risks, safety, and experience.

Cosmetic Approaches to Parotidectomy

The parotid gland is located in a cosmetically sensitive area. Given cultural emphasis on cosmesis, using minimally invasive or hidden incisions, when appropriate, can significantly improve patient satisfaction and quality of life following surgery. Facelift-style incisions have been used since the late 1960s to approach parotid pathology. Several alternative incisions, including technology-assisted approaches, also have been described in the literature. To that end, this article explore the existing data regarding several historical and emerging cosmetic approaches to the parotid gland comparing relative advantages and disadvantages of each.

Trans oral endoscopic thyroidectomy (TOETVA): First French experience in 90 patients

OBJECTIVE

Thyroidectomy techniques using extracervical approaches have grown in popularity for about 20 years and their feasibility has now been demonstrated. We wanted to evaluate one of these new approaches: the anterior vestibular endoscopic approach (TOETVA). The aim of this study was to evaluate the results of an initial series patients who underwent an anterior trans-vestibular endoscopic oral thyroidectomy.

METHODS

From February 2018 to September 2020, this technique was offered to patients aged 18 to 70, ASA I or II, who presented with an indication for thyroid surgery and who wished to avoid cervical scars. The approach was through the anterior vestibule of the mouth and the specimen was extracted either transorally or via the axilla depending on its size. Apart from the first ten cases, all patients underwent recurrent nerve neuromonitoring. The patients were operated on by two surgeons experienced in thyroid surgery. All the patients had follow-up visits on D15, D30 and at 2 months. The pre- and intra-operative data, length of stay and complications were evaluated.

RESULTS

A total of 90 consecutive patients (87 women) aged 46±12.4 years (18 to 69) with a mean BMI of 24.4±4 were included. The indications for surgery included 11 papillary cancers, 5 oncocytic nodules, 15 toxic nodules, 13 cases of Graves disease and 46 symptomatic goiters and/or nodules. The mean pre-operative diameter of the nodules was 3.61±1.99 (0.44 to 7.3) cm. The interventions performed were 44 lobo-isthmectomies, 41 total thyroidectomies and 5 isthmectomies. The mean operating time was 134±45min (40 to 255). On D1, the post-operative ionized calcium was 1.09±0.11mmol/L (4.3685±0.44mg/dL) (normal 0.8-1.15mmol/L) (3.206-4.609mg/dL)) and the total serum calcium was 2.07±0.11mmol/L 8.296±0.44mg/dL (normal 2.2-2.5mmol/L) (8.817-10.019mg/dL). Five patients underwent conversion from endoscopic to open cervical approach (5.5%). The complications were seven cases of transient recurrent nerve palsy (7.8%), eight cases of hypoparathyroidism (19%) including six transient and two permanent, one skin burn and 26 cases of transient chin numbness related to the electrocautery (29%). Ten patients (11%) presented with transient post-operative skin ecchymosis that resolved within 7-10 days. A spontaneous pneumo-mediastinum was observed on chest CT in three patients and evolved favorably. No hematoma, or surgical site infection, or complications related to axillary extraction were observed. All the patients declared themselves satisfied post-operatively and at the end of the follow-up.

CONCLUSION

The TOETVA route of entry is a safe and reliable technique in well-selected patients wishing to avoid a cervical scar.

Robotic-assisted parathyroidectomy via transaxillary approach: feasibility and learning curves

Background

There have been few reports of robotic-assisted transaxillary parathyroidectomy in the literature. We aim to report our experience with robotic-assisted transaxillary parathyroidectomy for primary hyperparathyroidism (PHPT) in the Western population.

Methods

A retrospective study was performed from July 2010 through July 2019 at two institutions, one in the United States and one in France. Demographic characteristics and perioperative data were collected for all patients undergoing robotic-assisted transaxillary parathyroidectomy by a single surgeon at each institution. A linear regression model was developed to describe the learning curve for this procedure at each institution.

Results

One-hundred and two patients with PHPT were included with a median age of 55.6±12.4 years and median body mass index (BMI) of 25.5±6.1 kg/m². The majority of patients were female (80.4%). Median total operative time was 116±53 minutes. Minor complications were reported in 2 patients (1.96%), and one case was converted to a trans-cervical approach (TCA) for four-gland exploration. Median patient follow-up time was 6.5±12.2 months, and disease recurrence was reported in one patient. Calculated learning curves showed that one surgeon achieved proficiency by the eighth case, and the other achieved proficiency by the fourteenth case.

Conclusions

This is the largest reported experience of robotic-assisted transaxillary parathyroidectomy for PHPT in the Asian and Western population. Analysis of the procedural learning curve demonstrates that proficiency in this technique was achieved after performance of less than 15 surgeries. This procedure is safe and feasible in the hands of experienced surgeons for select patients with localized disease.

Preferences for thyroidectomy technique: Comparing traditional and transoral approaches

BACKGROUND

We investigated preferences between the transcervical and transoral thyroidectomy approach in the United States and Israel.

METHODS

An online survey assessing scar attitudes and surgical preferences, in English and Hebrew, was distributed on ThyCa.com and other platforms.

RESULTS

928 and 339 responses from the United States and Israel cohorts, respectively, were analyzed. In both countries, individuals without prior thyroidectomy preferred a scarless approach when hypothetical risks equaled those of traditional thyroidectomy (77% United States, 76% Israel, p = 0.61). U.S. respondents without thyroidectomy had greater preference to avoid a scar and would pay more to do so than those with thyroidectomy (both p < 0.001). Many respondents with prior thyroidectomy still expressed interest in scarless alternatives (57% United States).

CONCLUSIONS

Populations in Israel and the United States prefer scarless thyroidectomy when risks equal the traditional approach. While individuals without prior thyroidectomy are more likely to favor a scarless option, former thyroidectomy patients may have preferred avoiding a scar.

The variable direct cost and cost drivers of transoral endoscopic thyroidectomy vestibular approach

Background

As transoral endoscopic thyroidectomy vestibular approach grows in popularity, there is a need for data on cost in order to better characterize its value to patients. To this end, we compared the variable direct cost of transoral endoscopic thyroidectomy vestibular approach and transcervical approach thyroidectomy and determined which factors drive the increased cost for the transoral approach.

Methods

Patients undergoing thyroid lobectomy and total thyroidectomy that met inclusion criteria for transoral endoscopic thyroidectomy vestibular approach, including those patients that opted for management via the transcervical approach, between 8/2016 and 4/2019 were reviewed. The variable direct cost for the surgical encounter was collected and means were compared between the transoral and transcervical cohorts for lobectomy and total thyroidectomy respectively. The operative time independent variable direct cost was similarly compared between cohorts.

Results

Out of 238 patients, 118 (50%) were managed via transoral endoscopic thyroidectomy vestibular approach and 120 (50%) were managed via transcervical approach thyroidectomy. Mean variable direct cost, our primary outcome, was $4,455 (SD 1,129, 95% CI: 4,204-4,706) for transoral lobectomy and $3,179 (SD 687, 95% CI: 2,990-3,369) for transcervical lobectomy [t(132.05)=8.09, P<0.001] representing a difference in cost of $1,276 (SD 158, 95% CI: 964-1,587). Mean variable direct cost was $4,681 (SD 829, 95% CI: 4,405-4,957) for transoral total thyroidectomy and $3,645 (SD 876, 95% CI: 3,431-3,858) for transcervical total thyroidectomy [t(79.92)=5.98, P<0.001], representing a difference in cost of $1,036 (SD 173, 95% CI: 691-1,381). Differences in energy devices alone account for $487.53 and $447.96 of the cost differences, respectively.

Conclusions

The differences in mean variable direct cost between transoral endoscopic vestibular approach and transcervical approach for lobectomy and total thyroidectomy were $1276 and $1036 respectively, amounts far less than some believe them to be. This data will be invaluable as we ultimately aim to define the value of transoral endoscopic thyroidectomy vestibular approach.

Transoral endoscopic parathyroidectomy vestibular approach: A systematic review

BACKGROUND

Transoral endoscopic parathyroidectomy vestibular approach (TOEPVA) is a novel surgical approach that has gained increasing traction as a remote access approach for parathyroid surgery. The primary aim of this systematic review is to assess the feasibility and safety of this approach.

METHODS

Several databases were screened for relevant citations. The quality of studies and risk of bias were evaluated using the MINORS scoring system.

RESULTS

Nine articles containing 78 cases of TOEPVA met the inclusion criteria. Overall, there was a 96% success rate. There were three cases (3.8%) that had complications, including one case of transient recurrent laryngeal nerve palsy. The average MINORS score of the studies suggested a moderate amount of bias.

CONCLUSIONS

Based on limited quality evidence, this review suggests that TOEPVA is safe and feasible, with reasonable success rates and low complication rates in a very carefully selected patient population. Further large-scale studies are warranted.

Predictive model of operative time in transoral endoscopic thyroidectomy vestibular approach

BACKGROUND

Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) has demonstrated excellent safety and is receiving wider use in North America. Understanding which factors lead to operative difficulty, as evaluated by operative time (OT), may help to improve safety and refine indications for this procedure.

METHODS

Cases of TOETVA performed at our institution were reviewed. Multivariate linear regression was performed using patient demographics, thyroid characteristics, and operative variables to predict OT.

RESULTS

A total of 207 cases were included for analysis. A multivariate linear regression model, controlling for age, sex, and BMI, was developed from 104 cases with an R² of 0.47 (p < 0.001). Cross-validation on 103 remaining cases showed root-mean-square error of 46.37. Total thyroidectomy and lobe size were the only significant predictors (p < 0.001).

CONCLUSIONS

We successfully developed a model to predict OT for TOETVA based on preoperative and operative variables. Lobe size, but not BMI, is a significant predictor of OT.
