Active surveillance is a feasible and safe strategy in selected patients with papillary thyroid cancer and suspicious cervical lymph nodes detected after thyroidectomy.

Objective: After initial treatment, up to 30% of patients with papillary thyroid cancer (PTC) have incomplete response, mainly cervical lymph node (LN) disease. Previous studies have suggested that active surveillance (AS) is a possible option for these patients. Our aim was to report the results of AS in patients with PTC and cervical LN disease. Materials and methods: In this retrospective observational study, we included adult patients treated and followed for PTC, who presented with cervical LN disease and were managed with AS. Growth was defined as an increase ≥ 3mm in either diameter. Results: We included 32 patients: 27 (84.4%) women, age of 39 ± 14 years, all initially treated with total thyroidectomy, and 22 (69%) with therapeutic neck dissection. Cervical LN disease was diagnosed 1 year (0.3-12.6) after initial management, with a diameter of 9.0 mm (6.0-19.0). After a median AS of 4.3 years (0.6-14.1), 4 (12.5%) patients had LNgrowth: 2 (50%) of whom were surgically removed, 1 (25%) was effectively treated with radiotherapy, and 1 (25%) had a scheduled surgery. Tg increase was the only predictive factor of LN growth evaluated as both the delta Tg (p < 0.0366) and percentage of Tg change (p < 0.0140). None of the included patients died, had local complications due to LN growth or salvage therapy, or developed distant metastases during follow-up. Conclusion: In selected patients with PTC and suspicious cervical LNs diagnosed after initial treatment, AS is a feasible and safe strategy as it allows effective identification and treatment of the minority of patients who progress.

Comparative analysis of GoPro and digital cameras in head and neck flap harvesting surgery video documentation: an innovative and efficient method for surgical education.

BACKGROUND: An urgent need exists for innovative surgical video recording techniques in head and neck reconstructive surgeries, particularly in low- and middle-income countries where a surge in surgical procedures necessitates more skilled surgeons. This demand, significantly intensified by the COVID-19 pandemic, highlights the critical role of surgical videos in medical education. We aimed to identify a straightforward, high-quality approach to recording surgical videos at a low economic cost in the operating room, thereby contributing to enhanced patient care. METHODS: The recording was comprised of six head and neck flap harvesting surgeries using GoPro or two types of digital cameras. Data were extracted from the recorded videos and their subsequent editing process. Some of the participants were subsequently interviewed. RESULTS: Both cameras, set at 4 K resolution and 30 frames per second (fps), produced satisfactory results. The GoPro, worn on the surgeon's head, moves in sync with the surgeon, offering a unique first-person perspective of the operation without needing an additional assistant. Though cost-effective and efficient, it lacks a zoom feature essential for close-up views. In contrast, while requiring occasional repositioning, the digital camera captures finer anatomical details due to its superior image quality and zoom capabilities. CONCLUSION: Merging these two systems could significantly advance the field of surgical video recording. This innovation holds promise for enhancing technical communication and bolstering video-based medical education, potentially addressing the global shortage of specialized surgeons.

Preoperative MRI-based endplate quality: a novel tool for predicting cage subsidence after anterior cervical spine surgery.

PURPOSE: The objective of this study was to examine the predictive value of a newly developed MRI-based Endplate Bone Quality (EBQ) in relation to the development of cage subsidence following anterior cervical discectomy and fusion (ACDF). METHODS: Patients undergoing ACDF for degenerative cervical diseases between January 2017 and June 2022 were included. Correlation between EBQ scores and segmental height loss was analyzed using Pearson's correlation. ROC analyses were employed to ascertain the EBQ cut-off values that predict the occurrence of cage subsidence. Multivariate logistic regression analyses were conducted to identify the risk factors associated with postoperative cage subsidence. RESULTS: 23 individuals (14.56%) exhibited the cage subsidence after ACDF. In the nonsubsidence group, the average EBQ and lowest T-score were determined to be 4.13 ± 1.14 and - 0.84 ± 1.38 g/cm2 respectively. In contrast, the subsidence group exhibited a mean EBQ and lowest T-score of 5.38 ± 0.47 (p < 0.001) and - 1.62 ± 1.34 g/cm2 (p = 0.014), respectively. There was a significant positive correlation (r = 0.798**) between EBQ and the segmental height loss. The EBQ threshold of 4.70 yielded optimal sensitivity (73.9%) and specificity (93.3%) with AUC of 0.806. Furthermore, the lowest T-score (p = 0.045, OR 0.667) and an elevated cervical EBQ score (p < 0.001, OR 8.385) were identified as significant risk factors for cage subsidence after ACDF. CONCLUSIONS: The EBQ method presents itself as a promising and efficient tool for surgeons to assess patients at risk of cage subsidence and osteoporosis prior to cervical spine surgery, utilizing readily accessible patient data.

Occipito-Cervico-Dorsal Flap for Neck Reconstruction After Postburn Contractures: A Case Report and Literature Review.

Because the head and neck are one of the most frequent locations of burns, it is of paramount importance that plastic surgeons and plastic surgical nurses understand the most effective surgical methods for treating neck contractures and the reconstructive technique required for each case. We introduce the case of a 42-year-old woman who presented with a severe postburn neck contracture that was reconstructed with a pedicled occipito-cervico-dorsal flap. We closed the donor-site wound primarily and completely covered the defect with good results. In addition to conventional skin grafts, dermal matrices, and microsurgical techniques, using an occipito-cervico-dorsal flap should be considered for reconstructing postburn neck contractures as it offers good aesthetic and functional outcomes, provides enough tissue and pliable skin, and results in minimal donor-site morbidity.

Anesthetic Management of a Patient with Madelung's Disease Presenting with a Giant Cervical Lipoma: A Case Report.

Madelung's disease is characterized by the presence of multiple symmetric and nonencapsulated facial, neck, and upper trunk lipomas. Depending on the location and size of lipomas, there may be concerns for difficult airway management and cardiovascular collapse. We present the anesthetic management case of a patient with cervical and mediastinal lipomas who underwent elective cervical lipoma resection.

Bedside preoperative predictors of difficult laryngeal exposure in microlaryngeal surgery.

PURPOSE: Successful microlaryngeal surgery relies on an adequate laryngeal exposure. Recognizing the likelihood of challenging exposure prior to microlaryngeal surgery may assist in selecting the appropriate surgical approach and even prompt consideration of alternative treatment options. We aim to apply the mini-Laryngoscore, a preoperative assessment tool, to our study population and incorporate novel variables to optimize the prediction model. METHODS: This single-center prospective cohort study included 80 consecutive patients undergoing elective microlaryngeal surgery, from January 1, to June 30, 2023. Each patient underwent a presurgical evaluation of 15 parameters and an intraoperative scoring of the anterior commissure visualization. These parameters were assessed for their association with difficult laryngeal exposure, using multiple logistic regression analysis. We created a novel prediction model for DLE and compared it with the existing model, the mini-Laryngoscore. RESULTS: Out of 80 patients, 24 (30%) patients had difficult laryngeal exposure, including 3 cases (3.8%) in which visualization of the anterior commissure was not possible. A large neck diameter (OR, 1.4; CI 1.1-1.9) and the presence of upper teeth (OR, 8.9; CI 1.3-62.8) were independent risk factors for a difficult laryngeal exposure, while a larger interincisors gap was the only independent protector factor (OR, 0.3; CI 0.1-0.8). The logistic regression model combining these three independent risk factors displayed a high discriminative value AUC = 0.89 (CI 0.81-0.97). The predictive performance of the mini-Laryngoscore was 0.73 (CI 0.62-0.85). CONCLUSION: Combining two parameters from the mini-Laryngoscore (upper jaw dental state and interincisors gap distance) with neck circumference measurement can accurately predict the risk of difficult laryngeal exposure.

A case of deep neck abscess treated with a disposable VSD wound care device: Case report and review of literature.

RATIONALE: Vacuum sealing drainage is a novel technique for wound treatment that is characterized by adequate drainage and promotes wound healing. We report a case in which negative pressure sealing drainage was applied to treat a deep cervical abscess and achieved a good therapeutic effect. PATIENT CONCERNS: The abscess in the neck will go down. DIAGNOSES: Deep neck abscess. INTERVENTIONS: The usual surgical approach to treating this condition is to make a small incision to incise and drain the patient infected area where it is most visibly swollen or fluctuating, and to place a negative pressure drainage device. OUTCOMES: Eleven days after the operation, the patient neck recovered well, there was no infection in the operation area, and the patient was discharged from the hospital with improved symptoms. LESSONS: This proves that the negative pressure closed drainage technique has potential in the treatment of deep neck abscesses and is also an effective choice in promoting wound healing, which is expected to bring better therapeutic effects to patients treated for deep neck abscesses.

Flap loss in head and neck reconstruction: Is there a singular cause for failure?

Despite the high success rates reported in head and neck reconstruction, free flap failures continue to persist. Understanding the factors associated with flap loss and improving overall success are paramount. This study aimed to comprehensively assess the factors influencing flap revision and free tissue transfer survival in head and neck reconstruction. The study included 70 patients with defects in the lower two-thirds of the head and neck region and underwent reconstruction using free flaps. Patient age, gender, smoking status, comorbidities and data on the location and aetiology of the defect, the specific type of flap employed, the recipient artery and vein chosen, instances of revision and the overall success of the flap were collected. The investigation aimed to establish correlations between these variables as well as flap success and revision rates. No statistically significant differences were observed in arterial and venous anastomosis revision rates, or flap survival, in relation to variables such as age, gender, flap type, smoking status, comorbidities, recipient artery or vein and the number of vein anastomoses. The malignant tumour group exhibited a lower requirement for arterial revision and a higher flap survival rate compared to the benign tumour group. This study underscores the comparable safety profiles of perforator-based and conventional flaps in head and neck reconstruction. Furthermore, it reveals that patient characteristics are not contraindications for free tissue transfer. Additionally, the quantity of the veins and choice of recipient vessels are flexible and do not significantly impact flap success. The higher rates of flap success in patients with malignant aetiology requires further investigation.

The influence of anterior cervical discectomy and fusion surgery on cervical muscles and the correlation between related muscle changes and surgical efficacy.

BACKGROUND: Anterior cervical discectomy and fusion surgery (ACDF) is a common technique in treating degenerative cervical spondylosis. This study is to evaluate the changes of cervical muscles after ACDF and analyze the correlation between related muscle changes and clinical efficacy. METHODS: Sixty-five postoperative patients (single-level ACDF) with cervical spondylotic myelopathy from January 2013 to December 2022 were analyzed. The measured parameters include: the axial section of longus colli cross-sectional area (AxCSA), the volume of cervical longus, the ratio of long and short diameter line (RLS), the cervical extensor cross-sectional area (CESA), the vertebral body area (VBA), and the CESA/VBA. The visual analog scale (VAS), modified Japanese Orthopedic Association score (mJOA), and neck disability index (NDI) were evaluated. The changes in muscle morphology were analyzed, and the correlation analysis was conducted between morphological changes and function scores. RESULTS: The postoperative AxCSA of surgical segment (3rd month, 12th month, and the last follow-up) was decreased compared to preoperative (141.62 ± 19.78), and the differences were significant (P < 0.05). The corresponding data reduced to (119.42 ± 20.08) mm2, (117.59 ± 19.69) mm2, and (117.41 ± 19.19) mm2, respectively (P < 0.05). The RLS increased, and the volume of cervical longus decreased significantly after surgery (P < 0.05). Negative correlation was found between postoperative volume of cervical longus and VAS at the 3rd month (r = - 0.412), 12th month (r = - 0.272), and last follow-up (r = - 0.391) (P < 0.05). Negative correlation existed between postoperative volume of cervical longus and NDI at the 3rd month (r = - 0.552), 12th month (r = - 0.293), and last follow-up (r = - 0.459) (P < 0.05). CONCLUSION: The volume of cervical longus decreased and its morphology changed after ACDF surgery. The mainly affected muscle was the cervical longus closing to the surgical segment. Negative correlation was found between the postoperative volume of cervical longus and function scores (VAS and NDI).

Surgical techniques and outcomes of thyroid chondroplasty in transfeminine individuals: A systematic review.

Thyroid chondroplasty (TC) in facial gender-affirming surgery (FGAS) is aimed at modifying the thyroid cartilage to achieve a more feminine laryngeal appearance. This study evaluated open versus endoscopic techniques to TC and associated outcomes and complications. A systematic review (SR) of articles pertaining to TC was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Twelve articles representing 368 patients were included for analysis. Nine articles described open approaches, and three articles described endoscopic techniques. The rate of total complications was 4.3% (n = 12) in the open approach compared to 15% (n = 13) in the endoscopic approach. Positive esthetic results were reported in 92% of cases performed with the open approach and 90% with the endoscopic approach. In the open approach, seven (2.5%) patients requested additional removal of cartilage, and three (1.1%) requested scar revision. In the endoscopic approach, three (3.7%) patients requested additional cartilage removal. In addition, data of individuals who underwent "cervical tracheoplasty" for gender dysphoria from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database was reviewed, and there was no incidence of wound or major complications among patients who underwent tracheoplasty alone. Although the advantage of the endoscopic approach is a scarless neck incision, the rate of complications is higher with the open approach. Endoscopic approaches are still not widely used, and continued investigations are warranted to improve familiarity with this approach and reduce postoperative complications.

Is identification and dissection of the external laryngeal nerve necessary during thyroidectomy? A prospective study.

BACKGROUND: Compared to the recurrent laryngeal nerve, the EBSLN (or external laryngeal nerve) is less studied in terms of its course and relationship with the thyroid gland. This is a prospective intraoperative study designed to identify the anatomical variations of the EBSLN in relation to the IPC, the superior thyroid pedicle, and the point where the nerve crosses the STA. Additionally, the study aims to propose a technical procedure for its preservation. METHODS: We conducted a prospective study of 50 patients (total of 100 nerves) undergoing total thyroidectomy at the Department of Surgery 'B' in Ibn Sina Hospital, Rabat. Intraoperatively, the EBSLN was visually identified and preserved before ligating the superior thyroid vessels. Each nerve was categorized using established classification systems. RESULTS: The overall pooled EBSLN identification rate was 82%. Cernea type IIa (nerves crossing the STA less than 1 cm above the upper edge of the superior thyroid pole) and Friedman type II (nerves piercing the lower fibers of the IPC) were the most prevalent (64% and 44%, respectively). Kierner type IV (nerves crossing the branches of the STA immediately above the upper pole of the thyroid gland) was represented in 27% of cases. CONCLUSION: A better understanding of surgical anatomy of the neck allows for better results of thyroidectomy by preserving the external and recurrent laryngeal nerves.

Cost Analysis of High-Signal Approach in Otolaryngology-Head and Neck Surgery Residency.

OBJECTIVE: The objective of this study is to analyze a high-signal approach for otolaryngology-head and neck surgery (OHNS) residency applicants and calculate cost savings for programs and applicants. METHODS: Data from both the 2022-2024 Electronic Residency Application Service (ERAS) and a data model were used to demonstrate cost savings with a high-signal approach. Modeled data assumed that the number of applications per applicant would be equal to the number of signals allowed. Predicted and real-world cost savings across the five other specialties participating in a high-signal approach were calculated. RESULTS: ERAS data cost savings for the entire OHNS applicant pool amounted to $365,950. In the modeled data, cost savings amounted to $825,921. When extrapolated to include all five high-signal specialties, total cost savings amounted to $2,570,464 (ERAS data) and $6,359,478 (modeled data). Otolaryngology programs were predicted to experience significant time savings, resulting in cost savings of $437,883 and $1,113,342 for ERAS data and modeled data, respectively. CONCLUSIONS: The study highlights the advantages of a high-signal approach, including financial advantages or increased time for programs to engage in holistic review and diversify the pool of interview candidates. Cost savings in this study were shown to be significant when extrapolated across all specialties using a high-signal approach. Further research is needed to optimize the signaling system and confirm the favorable interview distribution and equity data from the low-signal OHNS experience with a high-signal approach. LEVEL OF EVIDENCE: N/A Laryngoscope, 134:2684-2688, 2024.

Outcomes of Head and Neck Free Tissue Transfer Requiring Vein Grafting: Systematic Review and Meta-analysis.

OBJECTIVE: To systematically review the literature to determine the prevalence of free flap failure in head and neck free flaps requiring vein grafting. DATA SOURCES: Search strategies created in collaboration with a medical librarian were implemented using PubMed, Cochrane, Scopus, Web of Science, and Google Scholar from inception to August 2022. REVIEW METHODS: The population of interest included adult and pediatric patients undergoing reconstruction of oncologic or traumatic head and neck defects with a free flap requiring a vein graft that presents the success/failure rate. The primary outcome was the flap failure rate, and the secondary outcome was the flap compromise/revision rate. Inclusion and exclusion criteria were designed to capture all study designs. Initially, 2778 articles were identified by the search strategy. Two reviewers independently performed the review, data extraction for analysis, and a quality assessment. Primary Reporting Items for Systematic Reviews and Meta-analyses guidelines were followed. Meta-analysis was performed using a random effects model. RESULTS: Eleven studies of 789 flaps were included for data extraction. Random effects meta-analysis resulted in an estimated prevalence of free flap failure of 12.30% (95% confidence interval: 6.39%-19.49%, I2 = 77.4%). CONCLUSION: Taking into account that head and neck free tissue transfers that require a vein graft are typically associated with more challenging reconstructions and the lack of a suitable alternative, vein grafts appear to be a reliable method for bridging the gap between the flap and recipient vessels in head and neck free tissue transfer when indicated.

Biomechanical comparison of static and dynamic cervical plates in terms of the bone fusion, tissue degeneration, and implant behavior.

INTRODUCTION: Using an anterior cervical fixation device in the anterior cervical discectomy and fusion (ACDF) has evolved to various systems of static and dynamic cervical plates (SCP and DCP). Dynamic cervical plates have been divided into three categories: the rotational (DCP-R), translational (DCP-T), and hybrid (DCP-H) joints. However, little studies have been devoted to systematically investigate the biomechanical differences of dynamic cervical plates. MATERIALS AND METHODS: The biomechanical tests of load-deformation properties and failure modes between the SCP and DCP systems are implemented first by using the UHMWPE blocks as the vertebral specimens. The CT-based C2-C7 model simulates the strategies of cervical plate in ACDF surgery is developed with finite-element analyses. One intact, one SCP and two DCP systems are evaluated for their biomechanical properties of bone fusion and tissue responses. RESULTS: In the situation of biomechanical test, The mean values of the five ACDSP constructs are 393.6% for construct stiffness (p < 0.05) and 183.0% for the first yielding load (p < 0.05) less than those of the SCP groups, respectively. In the situation of finite-element analysis, the rigid-induced ASD is more severe for the SCP, followed by the DCP-H, and the DCP-R is the least. DISCUSSION AND CONCLUSIONS: Considering the degenerative degree of the adjacent segments and osteoporotic severity of the instrumented segments is necessary while using dynamic system. The mobility and stability of the rotational and translational joints are the key factors to the fusion rate and ASD progression. If the adjacent segments have been degenerative, the more flexible system can be adopted to compensate the constrained mobility of the ACDF segments. In the situation of the osteoporotic ACDF vertebrae, the stiffer system is recommended to avoid the cage subsidence.
