Adenoid cystic carcinoma of the parotid and submandibular glands in children and young adults: A population-based study.

OBJECTIVES: This study aims to analyze the behavior and treatment of adenoid cystic carcinoma (AdCC) in the pediatric and young adult population and to identify factors affecting overall survival (OS). MATERIALS AND METHODS: The study analyzed salivary gland malignancies in patients aged 0-21 with AdCC histology using the National Cancer Database from 2004 to 2018. RESULTS: A total of 72 patients (59.7% parotid, 36.1% submandibular, 1.4% sublingual, 2.8% unspecified) met criteria. Median age was 18 years [range: 0-21]. High-grade dysplasia was present in 67% of cases. Therapy consisted of primary surgery for all cases, regional lymph node dissection (LND) (74%), radiotherapy (71%), chemotherapy (8%), and chemoradiation (7%). The 5-year OS rate was 93.2% [95% confidence interval (CI): 86.9%-99.9%], respectively. Patients who underwent associated LND had improved OS (p = .0083, log-rank test) with a 5-year OS at 82.4% [95% CI: 66.1%-100%] versus 97.6% [95% CI: 93.0%-100%]. A significant difference in OS was found with unfavorable outcomes after positive marginal status: 5-year OS 84.1% [95% CI: 71.0%-99.7%] versus 100% [95% CI: 100%]; p < .001. Adjuvant therapy did not seem to impact the outcome. CONCLUSION: This study confirms that AdCC in children and young adults has an overall good prognosis despite frequent high grade. It suggests that cervical LND may be of importance, but the value of systematic adjuvant therapy is not confirmed. These findings emphasize the importance and relevance of population-based studies in shaping clinical practice and informing the design of future prospective investigations.

Early enteral nutrition and mobilization following head and neck surgery with free flap reconstruction.

BACKGROUND: Perioperative management methods that reduce surgery-associated invasiveness and improve the quality of postoperative recovery are being promoted as enhanced recovery after surgery programs in various areas. Early enteral nutrition and mobilization are essential elements for enhanced recovery after surgery; however, their safety and feasibility are unclear in head and neck surgery with free tissue transfer reconstruction. This study aimed to clarify these uncertainties. METHODS: This is a retrospective before-after study. From 2018 to 2022, 187 and 173 patients received conventional management on or before April 2020 and early management on or after May 2020, respectively. The conventional management and early management groups received enteral nutrition and mobilization on postoperative days 2 and 1, respectively. The primary outcome for safety assessment was the incidence of complications. The secondary outcome was the compliance rate of conventional management or early management for feasibility assessment and the length of hospital stay. RESULTS: The clinical tumour-node-metastasis stage and American Society of Anesthesiologists physical status showed significant differences between the groups. In multivariable analysis, the early management group demonstrated a significantly lower incidence of treatment-required complication classified Clavien-Dindo Grade 2 and above (odds ratio = 0.57; 95% confidence interval = 0.31-0.92) and lower wound infection (odds ratio = 0.53; 95% confidence interval = 0.31-0.92). The early management group had lower compliance rate than the conventional management group; however, no statistically significant difference was observed (79.8% vs. 85.0%, P = 0.21). CONCLUSION: Early management is safe and feasible following head and neck surgery with free tissue transfer reconstruction. It could reduce the complication rate and is considered a useful postoperative management method.

A retrospective database analysis of pediatric parathyroidectomies from the United Kingdom registry of endocrine and Thyroid Surgeons.

INTRODUCTION: The United Kingdom Registry of Endocrine and Thyroid Surgery (UKRETS) holds the largest database of pediatric parathyroidectomy cases globally. There are currently no quoted acceptable cure or complication rates in the literature. METHODS: This retrospective database analysis evaluates the efficacy and safety of targeted parathyroidectomy (tPTx) and bilateral neck exploration (BNE) in first-time parathyroidectomy for pediatric primary hyperparathyroidism (PHPT) through analysis of the UKRETS database (1995-2022). Pre-, intra- and postoperative outcomes were assessed and analyzed. RESULTS: 168 cases underwent parathyroidectomy; 25 (15%) familial and 143 (85%) sporadic PHPT. 69% were female with a mean age of 10 years (Range 0-17). BNE was the most common operative approach (61%; n = 103/168). The most frequently used imaging modality was US (80%; n = 135/168). Mean number of glands excised in familial cases was three compared to one gland in sporadic cases (p < 0.05). Familial cases had a significantly higher rate of postoperative hypocalcemia (32% vs. 9%, p < 0.05) and all were BNE. Cure rate was 96.9% (n = 127/131), with differences in cure rates that did not reach statistical significance (sporadic 98.2% vs. familial 90.5%, p = 0.06). Preoperative localization (image-positive or negative) made no difference to cure rates in either familial (90% vs. 91%, p = 0.94) or sporadic (97.5% vs. 100%, p = 0.4) cases. CONCLUSIONS: This analysis demonstrates that first-time pediatric parathyroidectomy for PHPT is safe and effective. Familial cases have a higher rate of postoperative hypocalcemia; therefore, parents should be informed of this when consented. Targeted parathyroidectomy is safe and effective in both sporadic and familial cases, as long as there is positive preoperative imaging.

Cervical Spinal Cord Stimulation for Failed Neck Surgery Syndrome.

PURPOSE OF REVIEW: Cervical spine pain with or without radicular symptoms is a common condition leading to high utilization of the healthcare system with over 10 million medical visits per year. Many patients undergo surgical interventions and unfortunately are still left with neck and upper extremity pain, sometimes referred to as "Failed Neck Surgery Syndrome." When these options fail, cervical spinal cord stimulation can be a useful tool to decrease pain and suffering as well as reduce prescription medication use. RECENT FINDINGS: Spinal cord stimulation is a well-established therapy for chronic back and leg pain and is becoming more popular for neck and upper extremity pain. Recent studies have explored cervical spinal cord stimulation with successful outcomes regarding improved pain scores, functional outcomes, and reduction of prescription medication use. Continued research into cervical spinal cord stimulation is essential for maximizing its therapeutic potential for patients with chronic neck and upper extremity pain. This review highlights the importance of cervical spinal cord stimulation as an option for patients with failed neck surgery syndrome.

Virtual surgical planning for mandibular reconstruction in an abbreviated admission pathway.

OBJECTIVES: Virtual Surgical Planning (VSP) creates individualized surgical plans for free flap reconstruction of mandibular defects. Prior studies indicate that VSP can offer cost benefits due to reduced operative time and length of stay (LOS). We assessed the impact of VSP in the context of a validated postoperative abbreviated LOS clinical pathway. METHODS: This study assessed patients undergoing VSP vs conventional fibular free flap reconstruction for mandibular defects (12/2015-10/2020) and their operative time, ischemia time, and LOS were evaluated. RESULTS: Forty-four patients underwent VSP reconstruction, while 52 patients underwent conventional reconstruction for mandibular defects. VSP was associated with significantly lower total operative time (6 h and 57 mins vs 7 h and 54 mins, p = 0.011), but not length of stay or ischemia time. Total OR time was significantly increased with increasing number of segments needed in both the VSP group (p = 0.002) and the conventional group (p = 0.015). CONCLUSION: Shorter operative times and LOS have been attributed to the use of VSP in free tissue transfers. It is argued that these reductions offset the added cost of VSP. Our study indicates that there is no cost benefit for VSP utilization due to a significantly reduced operative time with no impact on length of admission in an abbreviated admission clinical pathway following free tissue transfer.

Appraisal of clinical practice guidelines for salivary gland cancer management utilizing AGREE II instrument.

OBJECTIVE: Salivary gland cancers (SGC) are rare neoplasms which comprise 1-5 % of all head and neck cancers. SGCs can be managed by resection, radiosurgery, chemotherapy, or a combination of these. Our team appraised the quality of clinical practice guidelines (CPGs) for SGC treatment and management using the Appraisal of Guidelines for Research and Evaluation (AGREE-II) instrument. DATA SOURCES: PubMed, Scopus, & EMBASE were reviewed for CPGs regarding SGC management from database inception to January 1st, 2023. REVIEW METHODS: The AGREE-II instrument was used by 4 reviewers to independently evaluate guidelines. Domain scores were generated with a satisfactory threshold being >60 % - a "high" quality CPG required >4 satisfactory domains. Intraclass correlation coefficients (ICCs) were used, via R 4.2.1., to determine inter-reviewer variability. RESULTS: Literature review identified 645 articles, with six being included after applying inclusion and exclusion criteria. Of the six included articles, one CPG was "high" quality and 5 were "low" quality. The domains with the highest scores were "Editorial Independence" (72.57 ± 36.60) and "Clarity and Presentation" (63.19 ± 26.08), while the lowest were "Rigor of Development" (34.03 ± 30.63) and "Applicability" (30.21 ± 30.46). ICC scores for each domain ranged from 0.937 to 0.983, indicating a high level of inter-rater agreement. CONCLUSION: This study found that most CPGs for the treatment and management of SGC were of "low" quality, with only one guideline being considered "high" quality based on the standard set by the AGREE-II instrument. These findings indicate that there is a high level of variability and little standardization when it comes to the quality of CPGs.

Surgical site antiseptic preparations for otolaryngology - Head and neck surgery: A current review.

OBJECTIVE: To review current literature and guidelines on antiseptic surgical site preparations for preventing surgical site infections with consideration of contraindications specific to head and neck surgery. DATA SOURCES: PubMed/MEDLINE, clinicaltrials.gov, accessdata.fda.gov, Manufacturer websites. REVIEW METHODS: A scoping review on the literature and clinical studies comparing the efficacy of different surgical site preparations. Studies were included if they were a randomized controlled trial (RCT) comparing at least two commonly used and available antiseptic preparations. Additionally, a compilation of warnings and contraindications from manufacturer labels and articles are included. Due to the lack of randomized controlled trials concerning antiseptic preparation use in head and neck surgery specifically, an additional search was executed for articles not limited to randomized controlled trials that compared different antiseptic preparation used in surgeries concerning the head and neck. RESULTS: Of 56,983 resulting abstracts and 3798 of them being screened, 25 RCTs were included. These RCTs included a variety of surgeries including gastrointestinal, obstetric, gynecologic, orthopedic, and vascular procedures. When searching for abstracts concerning head and neck surgeries, 9 studies were found and included. CONCLUSIONS: To reduce surgical site infections and avoid application in situations with contraindications, practicing surgeons need to be familiar with the existing literature regarding different surgical preparations and what warnings manufacturers have listed on the products. Optimal surgical site preparation for head and neck surgery is challenging as proximity to oxygen contraindicates newer alcohol-based options that are potentially flammable. We summarize evidence-based surgical site preparation for head and neck surgery.

Treatment of hyoid bone syndrome with surgical excision: our monocentric experience in the past five years.

PURPOSE: In 1968, Steinmann described the hyoid bone syndrome as a degenerative and inflammatory insertion tendinosis. It causes unilateral pain in the neck, increased by swallowing and palpation. The treatment is conservative, but when this fails, surgery is an option. Our aim is to assess the post-operative outcome of patients for whom a surgical hyoid bone resection procedure was performed in the University Hospital of Antwerp (UZA). METHODS: A retrospective study was performed. Patients were seen at the laryngology clinic in the UZA from 2018 until 2023. They were diagnosed with the hyoid bone syndrome based on anamnesis and clinical examination. Pre-operative imaging was performed to evaluate for anatomical changes and fiberoptic laryngoscopy performed to exclude other causes. Pre- and postoperative VAS pain scores were questioned. RESULTS: Seventeen patients were operated, two of them bilaterally. All patients had pain located to the affected side, and almost half of patients (n = 7) had dysphagia. On imaging, 10 patients had an elongated styloid process and 7 had calcification of the stylohyoid ligament. All patients underwent resection of the greater horn of the hyoid bone, 13 patients underwent resection of the stylohyoid ligament and in 9 patients the superior horn of the thyroid cartilage was removed. Mean pre-operative VAS pain score was 9 (/10) and mean postoperative score was 1.3 (/10). CONCLUSION: Our preliminary results show a good clinical effect of the surgical excision procedure and offer insight in the hyoid bone syndrome. Follow-up is necessary to assess the long-term results and potential recurrence of symptoms.

Chronic heart failure in patients undergoing major head and neck surgery: A hospital-based study.

OBJECTIVE: To investigate the effects of chronic heart failure on various post-operative outcomes in head and neck cancer patients undergoing major cancer surgery. STUDY DESIGN: For this retrospective cohort study of patients undergoing major head and neck cancer surgery, a sample of 10,002 patients between 2017 and 2019 were identified through the Nationwide Inpatient Sample. SETTING: Patients were selected as undergoing major head and neck cancer surgery, defined as laryngectomy, pharyngectomy, glossectomy, neck dissection, mandibulectomy, and maxillectomy, then separated based on pre-surgical diagnosis of chronic heart failure. METHODS: The effects of pre-operative chronic heart failure on post-surgical outcomes in these patients were investigated by univariable and multivariable logistic regression using ICD-10 codes and SPSS. RESULTS: A diagnosis of chronic heart failure was observed in 265 patients (2.6 %). Patients with chronic heart failure had more preexisting comorbidities when compared to patients without chronic heart failure (mean ± SD; 4 ± 1 vs. 2 ± 1). Multivariable logistic regression showed that chronic heart failure patients had significantly greater odds of dying during hospitalization (OR 2.86, 95 % CI 1.38-5.91) and experiencing non-routine discharge from admission (OR 1.89, 95 % CI 1.41-2.54) after undergoing major head and neck cancer surgery. CONCLUSION: Chronic heart failure is associated with greater length of stay and hospital charges among head and neck cancer patients undergoing major head and neck cancer surgeries. Chronic heart failure patients have significantly greater rates of unfavorable post-operative outcomes, including death during hospitalization and non-routine discharge from admission.

Accuracy of ChatGPT-3.5 and -4 in providing scientific references in otolaryngology-head and neck surgery.

INTRODUCTION: Chatbot generative pre-trained transformer (ChatGPT) is a new artificial intelligence-powered language model of chatbot able to help otolaryngologists in practice and research. We investigated the accuracy of ChatGPT-3.5 and -4 in the referencing of manuscripts published in otolaryngology. METHODS: ChatGPT-3.5 and ChatGPT-4 were interrogated for providing references of the top-30 most cited papers in otolaryngology in the past 40 years including clinical guidelines and key studies that changed the practice. The responses were regenerated three times to assess the accuracy and stability of ChatGPT. ChatGPT-3.5 and ChatGPT-4 were compared for accuracy of reference and potential mistakes. RESULTS: The accuracy of ChatGPT-3.5 and ChatGPT-4.0 ranged from 47% to 60%, and 73% to 87%, respectively (p < 0.005). ChatGPT-3.5 provided 19 inaccurate references and invented 2 references throughout the regenerated questions. ChatGPT-4.0 provided 13 inaccurate references, while it proposed only one invented reference. The stability of responses throughout regenerated answers was mild (k = 0.238) and moderate (k = 0.408) for ChatGPT-3.5 and 4.0, respectively. CONCLUSIONS: ChatGPT-4.0 reported higher accuracy than the free-access version (3.5). False references were detected in both 3.5 and 4.0 versions. Practitioners need to be careful regarding the use of ChatGPT in the reach of some key reference when writing a report.

PURPOSE: The usage of Chatbots as a kind of Artificial Intelligence in medicine is getting to increase in recent years. UpToDate® is another well-known search tool established on evidence-based knowledge and is used daily by doctors worldwide. In this study, we aimed to investigate the usefulness and reliability of ChatGPT compared to UpToDate in Otorhinolaryngology and Head and Neck Surgery (ORL-HNS). MATERIALS AND METHODS: ChatGPT-3.5 and UpToDate were interrogated for the management of 25 common clinical case scenarios (13 males/12 females) recruited from literature considering the daily observation at the Department of Otorhinolaryngology of Ege University Faculty of Medicine. Scientific references for the management were requested for each clinical case. The accuracy of the references in the ChatGPT answers was assessed on a 0-2 scale and the usefulness of the ChatGPT and UpToDate answers was assessed with 1-3 scores by reviewers. UpToDate and ChatGPT 3.5 responses were compared. RESULTS: ChatGPT did not give references in some questions in contrast to UpToDate. Information on the ChatGPT was limited to 2021. UpToDate supported the paper with subheadings, tables, figures, and algorithms. The mean accuracy score of references in ChatGPT answers was 0.25-weak/unrelated. The median (Q1-Q3) was 1.00 (1.25-2.00) for ChatGPT and 2.63 (2.75-3.00) for UpToDate, the difference was statistically significant (p < 0.001). UpToDate was observed more useful and reliable than ChatGPT. CONCLUSIONS: ChatGPT has the potential to support the physicians to find out the information but our results suggest that ChatGPT needs to be improved to increase the usefulness and reliability of medical evidence-based knowledge.

ChatGPT-4 accuracy for patient education in laryngopharyngeal reflux.

INTRODUCTION: Chatbot Generative Pre-trained Transformer (ChatGPT) is an artificial intelligence-powered language model chatbot able to help otolaryngologists in practice and research. The ability of ChatGPT in generating patient-centered information related to laryngopharyngeal reflux disease (LPRD) was evaluated. METHODS: Twenty-five questions dedicated to definition, clinical presentation, diagnosis, and treatment of LPRD were developed from the Dubai definition and management of LPRD consensus and recent reviews. Questions about the four aforementioned categories were entered into ChatGPT-4. Four board-certified laryngologists evaluated the accuracy of ChatGPT-4 with a 5-point Likert scale. Interrater reliability was evaluated. RESULTS: The mean scores (SD) of ChatGPT-4 answers for definition, clinical presentation, additional examination, and treatments were 4.13 (0.52), 4.50 (0.72), 3.75 (0.61), and 4.18 (0.47), respectively. Experts reported high interrater reliability for sub-scores (ICC = 0.973). The lowest performances of ChatGPT-4 were on answers about the most prevalent LPR signs, the most reliable objective tool for the diagnosis (hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH)), and the criteria for the diagnosis of LPR using HEMII-pH. CONCLUSION: ChatGPT-4 may provide adequate information on the definition of LPR, differences compared to GERD (gastroesophageal reflux disease), and clinical presentation. Information provided upon extra-laryngeal manifestations and HEMII-pH may need further optimization. Regarding the recent trends identifying increasing patient use of internet sources for self-education, the findings of the present study may help draw attention to ChatGPT-4's accuracy on the topic of LPR.

BACKGROUND: The widespread diffusion of Artificial Intelligence (AI) platforms is revolutionizing how health-related information is disseminated, thereby highlighting the need for tools to evaluate the quality of such information. This study aimed to propose and validate the Quality Assessment of Medical Artificial Intelligence (QAMAI), a tool specifically designed to assess the quality of health information provided by AI platforms. METHODS: The QAMAI tool has been developed by a panel of experts following guidelines for the development of new questionnaires. A total of 30 responses from ChatGPT4, addressing patient queries, theoretical questions, and clinical head and neck surgery scenarios were assessed by 27 reviewers from 25 academic centers worldwide. Construct validity, internal consistency, inter-rater and test-retest reliability were assessed to validate the tool. RESULTS: The validation was conducted on the basis of 792 assessments for the 30 responses given by ChatGPT4. The results of the exploratory factor analysis revealed a unidimensional structure of the QAMAI with a single factor comprising all the items that explained 51.1% of the variance with factor loadings ranging from 0.449 to 0.856. Overall internal consistency was high (Cronbach's alpha = 0.837). The Interclass Correlation Coefficient was 0.983 (95% CI 0.973-0.991; F (29,542) = 68.3; p < 0.001), indicating excellent reliability. Test-retest reliability analysis revealed a moderate-to-strong correlation with a Pearson's coefficient of 0.876 (95% CI 0.859-0.891; p < 0.001). CONCLUSIONS: The QAMAI tool demonstrated significant reliability and validity in assessing the quality of health information provided by AI platforms. Such a tool might become particularly important/useful for physicians as patients increasingly seek medical information on AI platforms.

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.

The right lymphatic duct: basic anatomy and clinical relevance.

The anatomical variability of the thoracic duct and the right lymphatic duct predisposes them to inadvertent damage following head and neck surgery thereby leading to chyle leak which is an uncommon complication with potentially significant associated morbidity. Although chyle leak is predominately associated with left-sided neck surgery, it also occurs as a complication of the right-sided neck dissection. Variable figures concerning chyle leakage after right-sided neck dissections were reported, ranging from 0 per cent to higher prevalences such as 14%, 24%, 33% and 60% of total cases of chyle leakages associated with neck surgery. The right-sided complications may implicate the right lymphatic duct and right-sided terminations of the thoracic duct into the venous system which occur in about 1-6% of humans. Other clinically relevant conditions involving the right-sided major lymphatic vessels include chyle leaks following right anterior cervical spine surgery, cysts of the right lymphatic duct and dilatation of the right lymphatic duct in the setting of recurrent cervical swelling. This article presents a review of the literature concerning the basic anatomy and the clinical relevance of the right lymphatic duct and the right-sided terminations of the thoracic duct into the venous circulation.

Spindle cell lipoma, a rare entity affecting the larynx: A case report.

Spindle cell lipoma is a very rare occurrence in the larynx and can be cured by complete excision. In this case report we present the case of a 71-year-old female who presented to the otorhinolaryngology outpatient department of Northwest General Hospital and Research Centre, Peshawar, with complaints of occasional irritation and a foreign body sensation in the throat while swallowing, for the last three years. She had undergone a surgical procedure 30 years back for the same complaint and remained asymptomatic till three years back. On examination, through fibre-optic laryngoscope, the attending surgeon saw an abnormal mass arising from the aryepiglottic folds of the larynx. An excisional biopsy was performed through micro-laryngoscopy. The patient's symptoms subsequently improved and she is currently doing well. Histopathological reports confirmed it as spindle cell lipoma.
