Speech and swallowing outcomes after laryngectomy for the dysfunctional irradiated larynx.

PURPOSE: To characterize outcomes of total laryngectomy for the dysfunctional larynx after radiation. METHODS: Retrospective case series of all subjects who underwent total laryngectomy for the irradiated dysfunctional larynx between 2000 and 2018 at an NCI-designated comprehensive cancer center at a single tertiary care academic medical center. Main outcomes included enteral tube feeding dependency, functional tracheoesophageal speech, and number and timing of postoperative pharyngeal dilations. RESULTS: Median time from radiation to laryngectomy was 2.8 years (range 0.5-27 years). Functional outcomes were analyzed for the 32 patients with 1-year follow-up. Preoperatively, 81% required at least partial enteral tube feeding, as compared to 34% 1-year postoperatively (p = 0.0003). At 1 year, 81% had achieved functional tracheoesophageal speech, which was associated with cricopharyngeal myotomy (p = 0.04, HR 0.04, 95% CI 0.002-0.949). There were 34% of subjects who required at least one pharyngeal dilation for stricture by 1 year postoperatively. Over half (60%) of the cohort were dilated over the study period. CONCLUSIONS: Laryngectomy for the dysfunctional larynx improves speech and swallowing outcomes in many patients. Cricopharyngeal myotomy is associated with improved postoperative voice. While the need for enteral feeding is decreased, persistent postoperative swallowing dysfunction is common. Careful patient selection and education regarding functional expectations are paramount.

Elective Paratracheal Lymph Node Dissection in Salvage Laryngectomy.

BACKGROUND: Indications for and efficacy of paratracheal nodal dissection (PTND) in patients undergoing laryngectomy (salvage) for persistent or recurrent laryngeal squamous cell carcinoma are not well-defined. METHODS: A retrospective cohort study was performed for patients undergoing salvage laryngectomy with clinically and radiographically negative neck disease between 1998 and 2015 (n = 210). Univariate and multivariate Cox regression analyses were performed. RESULTS: PTND was performed on 77/210 patients (36%). The PTND cohort had a greater proportion of advanced T classification (rT3/rT4) tumors (78%) than subjects without PTND (55%; p = 0.001). There was a 14% rate of occult nodal metastases in the paratracheal basin; of these, 55% did not have pathologic lateral neck disease. Multivariate analysis controlling for tumor site, tumor stage, and pathologic lateral neck disease demonstrated that PTND was associated with improved overall survival [OS] (p = 0.03; hazard ratio [HR] 0.60, 95% confidence interval [CI] 0.38-0.96), disease-free survival [DFS] (p = 0.03; HR 0.55, 95% CI 0.31-0.96), and distant DFS survival (p = 0.01; HR 0.29, 95% CI 0.11-0.77). The rate of hypocalcemia did not differ between subjects who underwent bilateral PTND, unilateral PTND, or no PTND (p = 0.19 at discharge, p = 0.17 at last follow-up). CONCLUSIONS: PTND at the time of salvage laryngectomy was more common in patients with rT3/rT4 tumors and was associated with improved OS and DFS, with no effect on hypocalcemia. In patients undergoing PTND, the finding of occult paratracheal metastases was often independent of lateral neck metastases.

AluY-mediated germline deletion, duplication and somatic stem cell reversion in UBE2T defines a new subtype of Fanconi anemia.

Fanconi anemia (FA) is a rare inherited disorder clinically characterized by congenital malformations, progressive bone marrow failure and cancer susceptibility. At the cellular level, FA is associated with hypersensitivity to DNA-crosslinking genotoxins. Eight of 17 known FA genes assemble the FA E3 ligase complex, which catalyzes monoubiquitination of FANCD2 and is essential for replicative DNA crosslink repair. Here, we identify the first FA patient with biallelic germline mutations in the ubiquitin E2 conjugase UBE2T. Both mutations were aluY-mediated: a paternal deletion and maternal duplication of exons 2-6. These loss-of-function mutations in UBE2T induced a cellular phenotype similar to biallelic defects in early FA genes with the absence of FANCD2 monoubiquitination. The maternal duplication produced a mutant mRNA that could encode a functional protein but was degraded by nonsense-mediated mRNA decay. In the patient's hematopoietic stem cells, the maternal allele with the duplication of exons 2-6 spontaneously reverted to a wild-type allele by monoallelic recombination at the duplicated aluY repeat, thereby preventing bone marrow failure. Analysis of germline DNA of 814 normal individuals and 850 breast cancer patients for deletion or duplication of UBE2T exons 2-6 identified the deletion in only two controls, suggesting aluY-mediated recombinations within the UBE2T locus are rare and not associated with an increased breast cancer risk. Finally, a loss-of-function germline mutation in UBE2T was detected in a high-risk breast cancer patient with wild-type BRCA1/2. Cumulatively, we identified UBE2T as a bona fide FA gene (FANCT) that also may be a rare cancer susceptibility gene.

Interprofessional education through service-learning: lessons from a student-led free clinic.

The academic community must replicate and strengthen existing models for interprofessional education (IPE) to meet widespread calls for team-based patient-centered care. One effective but under-explored possibility for IPE is through student-led clinics, which now exist in the majority of medical schools. This short report presents the Indiana University Student Outreach Clinic (IU-SOC), which involves seven different professional programs across three institutions, as a model for how IPE can be delivered formally through service learning. Lessons learned, such as nurturing an intentional interprofessional program, structured orientation and reflection, and resource and knowledge sharing between the clinic and academic institutions, can be applied to all student-led clinics, but also can inform other IPE initiatives in health professional curricula.

Multicancer Early Detection Tests: A State-of-the-Art Review for Otolaryngologists.

Objective: To provide a review of the science and applicability of current multi-cancer early detection (MCED) tests for otolaryngologists. Data Sources: PubMed, clinicaltrials.gov, company websites. Review Methods: Using PRISMA methodology, primary literature regarding MCED tests was queried from April 26 to May 12, 2024 using MCED search terms. Ongoing clinical trials incorporating MCED screens were identified via the National Institutes of Health clinicaltrials.gov website. Company websites for available or upcoming MCED tests were reviewed. Conclusion: Long-term robust data regarding the performance characteristics, effects on clinical outcomes, and cost-utility of MCED tests for head and neck cancer are currently lacking. Otolaryngologists should be aware of the implications of MCED tests as these assays become more widely used. Implications for Practice: Although not FDA-approved or covered by insurances at the time of writing of this manuscript, MCED testing is rapidly gaining interest, and patients with positive tests are presenting to otolaryngologists for evaluation. While MCED technologies hold great promise for early detection of disease and potential reduction of morbidity and mortality, more study is needed about their utility for head and neck cancer and optimal diagnostic workflows.

Gender Bias in Artificial Intelligence-Written Letters of Reference.

OBJECTIVE: Letters of reference (LORs) play an important role in postgraduate residency applications. Human-written LORs have been shown to carry implicit gender bias, such as using more agentic versus communal words for men, and more frequent doubt-raisers and references to appearance and personal life for women. This can result in inequitable access to residency opportunities for women. Given the known gendered language often unconsciously inserted into human-written LORs, we sought to identify whether LORs generated by artificial intelligence exhibit gender bias. STUDY DESIGN: Observational study. SETTING: Multicenter academic collaboration. METHODS: Prompts describing identical men and women applying for Otolaryngology residency positions were created and provided to ChatGPT to generate LORs. These letters were analyzed using a gender-bias calculator which assesses the proportion of male- versus female-associated words. RESULTS: Regardless of the gender, school, research, or other activities, all LORs generated by ChatGPT showed a bias toward male-associated words. There was no significant difference between the percentage of male-biased words in letters written for women versus men (39.15 vs 37.85, P = .77). There were significant differences in gender bias found by each of the other discrete variables (school, research, and other activities) chosen. CONCLUSION: While ChatGPT-generated LORs all showed a male bias in the language used, there was no gender bias difference in letters produced using traditionally masculine versus feminine names and pronouns. Other variables did induce gendered language, however. ChatGPT is a promising tool for LOR drafting, but users must be aware of potential biases introduced or propagated through these technologies.

Impact of Adjuvant Interferon Therapy on Survival Outcomes for Cutaneous Melanoma With Parotid Involvement.

OBJECTIVES: To determine the relative 5-year overall survival (OS) and 5-year recurrence-free survival (RFS) outcomes for adjuvant interferon therapy in the treatment of head and neck cutaneous melanoma (HNCM) with parotid gland involvement. METHODS: A retrospective cohort study was conducted at a single tertiary care institution to analyze patients undergoing parotidectomy for cutaneous head and neck melanoma involving the parotid gland from 2000 to 2014. Time-to-event analyses were performed using Kaplan-Meier curves with log-rank p-values and Cox proportional hazards models. RESULTS: The sample consisted of 82 patients who underwent surgical resection of stage III HNCM with parotid involvement. The mean follow-up was 67.8 months (SD 65) after diagnosis. Twenty-one patients received adjuvant interferon therapy, 12 patients received adjuvant radiation therapy, and 49 patients received no adjuvant therapy. Crude 5-year OS rates were 95.0% for interferon therapy, 33.3% for adjuvant RT, and 40.4% for no adjuvant therapy. Crude 5-year RFS rates were 75.2%, 19.5%, and 40.8% respectively. In the fully adjusted model, adjuvant interferon therapy was associated with improved 5-year OS compared to adjuvant RT (HR 0.10, 95% CI 0.011-0.837; p = 0.034). There was no significant association between adjuvant interferon therapy and 5-year RFS in the fully adjusted model. CONCLUSION: Adjuvant interferon therapy for surgically resected stage III cutaneous melanoma with parotid gland involvement may be associated with improved survival outcomes. These findings support the growing evidence for the use of immunotherapy in melanoma, and potentially a unique role for when melanoma involves the lymphatic-rich parotid gland.

Portrait of a Surgeon: Artificial Intelligence Reflections.

Text-to-image artificial intelligence (AI) programs are popular public-facing tools that generate novel images based on user prompts. Given that they are trained from Internet data, they may reflect societal biases, as has been shown for text-to-text large language model programs. We sought to investigate whether 3 common text-to-image AI systems recapitulated stereotypes held about surgeons and other health care professionals. All platforms queried were able to reproduce common aspects of the profession including attire, equipment, and background settings, but there were differences between programs most notably regarding visible race and gender diversity. Thus, historical stereotypes of surgeons may be reinforced by the public's use of text-to-image AI systems, particularly those without procedures to regulate generated output. As AI systems become more ubiquitous, understanding the implications of their use in health care and for health care-adjacent purposes is critical to advocate for and preserve the core values and goals of our profession.

Pedicled osteomyocutaneous pectoralis major flap with osseous rib harvest for salvage mandibular reconstruction: Case and technique.

In the era of free flap reconstruction, mandibular defects are routinely reconstructed with osseous free flaps, and non-free flap bony reconstruction options are limited. A patient with T4N0 mandibular squamous cell carcinoma underwent resection with fibula free flap reconstruction of a parasymphyseal to angle defect. After free flap failure due to venous congestion, the flap was explanted. He declined additional free flap reconstruction and elected to proceed with pedicled osteomyocutaneous pectoralis major with rib. In this case presentation, we discuss the technical details of harvest of this flap using the 6th rib. The pedicled osteomyocutaneous pectoralis major flap with osseous rib harvest, which is infrequently described in the literature, remains a viable option for bony reconstruction, particularly in the salvage setting.

The osteocutaneous radial forearm free flap: A pictorial essay.

The osteocutaneous radial forearm free flap (OCRFFF) is a versatile flap with the ability to reconstruct complex defects. We detail the techniques necessary to harvest an OCRFFF, including an outline on making 90-degree osteotomies to maximize bone harvest. In this pictorial essay, we provide illustrations of the anatomy and surgical techniques necessary for OCRFFF harvest. Detailed discussion is provided on how to protect the perforators to the bone and the approach to making osteotomies in a 90-degree fashion. The approach for prophylactic plating of the radius to prevent radius fractures is outlined. A case presentation on the real-life utilization of this flap is included. The OCRFFF is an excellent head and neck reconstructive option. While there are limitations to its use for patients requiring dental rehabilitation or long/anterior mandibular defects, for the right patient and indication it has shown great success in reconstructive efforts.

The osteocutaneous radial forearm free flap: A multidisciplinary review of the evidence.

The osteocutaneous radial forearm (OCRFF) is a versatile free flap option for bony defects of the head and neck, given the thinness and pliability of the forearm cutaneous paddle, pedicle length, reliability, lack of atherosclerosis, and functional concerns common to other osseous donor sites. The OCRFF was once associated with a high risk of radial fracture, in addition to concerns about the quality and durability of bone stock for osseous reconstruction, particularly for the mandible. Following the introduction of prophylactic plating of the radius, the incidence of symptomatic radial fracture has drastically decreased. Furthermore, modifications of the bony osteotomies and other evolutions of this flap harvest have increased the use of the OCRFF throughout the head and neck. Despite these advantages, the OCRFF is not widely utilized by microvascular reconstructive surgeons due to perceived limitations and risks. Herein, we present a multidisciplinary, contemporary review of the harvest technique, outcomes, and perioperative management for the OCRFF.

National Trends in 30-Day Readmission Following Transoral Robotic Surgery for Oropharyngeal Squamous Cell Carcinoma.

Importance: As the incidence of oropharyngeal squamous cell carcinoma (OPSCC) continues to rise in the US, an increasing number of patients are being treated with transoral robotic surgery (TORS). Readmission following surgery can potentially delay initiation of adjuvant treatment and affect survival outcomes. Objective: To identify risk factors for 30-day postoperative readmission in patients undergoing TORS for OPSCC. Design, Setting, and Participants: This retrospective, population-based cohort study used data from the Nationwide Readmissions Database from 2010 to 2017. All patients undergoing TORS for OPSCC were identified using International Classification of Diseases codes and included. Exclusion criteria were age younger than 18 years or incomplete information regarding index admission or readmission. The analysis was performed from April to October 2023. Exposure: TORS for OPSCC. Main Outcomes and Measures: Univariate and multivariate analyses were performed to determine factors associated with 30-day readmission. Covariates included demographics and medical comorbidities, socioeconomic factors, hospital characteristics, and surgical details. Trends in readmission over time, reasons for readmission, and characteristics of the readmission were also examined. Results: A weighted total of 5544 patients (mean [SD] age, 60.7 [0.25] years; 4475 [80.7%] male) underwent TORS for OPSCC. The overall readmission rate was 17.5% (n = 971), and these rates decreased over the study period (50 of 211 patients [23.7%] in 2010 vs 58 of 633 patients [9.1%] in 2017). Risk factors associated with readmission included male sex (adjusted odds ratio [AOR], 1.54; 95% CI, 1.07-2.20) and a diagnosis of congestive heart failure (AOR, 2.42; 95% CI, 1.28-4.58). Factors associated with decreased rate of readmission included undergoing concurrent selective neck dissection (AOR, 0.30; 95% CI, 0.22-0.41). Among the 971 readmissions, the most common readmission diagnoses were bleeding (151 [15.6%]), electrolyte and digestive problems (44 [4.5%]), pneumonia (44 [4.5%]), and sepsis (26 [2.7%]). Conclusions and Relevance: In this cohort study, readmission rates following TORS for oropharynx cancer decreased over time; however, a subset of patients required readmission most commonly related to bleeding, infection, and electrolyte imbalance. Concurrent neck dissection may be protective against readmission. Elucidation of risk factors for readmission after TORS for OPSCC offers opportunities for evidence-based shared decision-making, quality improvement initiatives, and improved patient counseling.

Evaluating the Accuracy of ChatGPT in Common Patient Questions Regarding HPV+ Oropharyngeal Carcinoma.

OBJECTIVES: Large language model (LLM)-based chatbots such as ChatGPT have been publicly available and increasingly utilized by the general public since late 2022. This study sought to investigate ChatGPT responses to common patient questions regarding Human Papilloma Virus (HPV) positive oropharyngeal cancer (OPC). METHODS: This was a prospective, multi-institutional study, with data collected from high volume institutions that perform >50 transoral robotic surgery cases per year. The 100 most recent discussion threads including the term "HPV" on the American Cancer Society's Cancer Survivors Network's Head and Neck Cancer public discussion board were reviewed. The 11 most common questions were serially queried to ChatGPT 3.5; answers were recorded. A survey was distributed to fellowship trained head and neck oncologic surgeons at 3 institutions to evaluate the responses. RESULTS: A total of 8 surgeons participated in the study. For questions regarding HPV contraction and transmission, ChatGPT answers were scored as clinically accurate and aligned with consensus in the head and neck surgical oncology community 84.4% and 90.6% of the time, respectively. For questions involving treatment of HPV+ OPC, ChatGPT was clinically accurate and aligned with consensus 87.5% and 91.7% of the time, respectively. For questions regarding the HPV vaccine, ChatGPT was clinically accurate and aligned with consensus 62.5% and 75% of the time, respectively. When asked about circulating tumor DNA testing, only 12.5% of surgeons thought responses were accurate or consistent with consensus. CONCLUSION: ChatGPT 3.5 performed poorly with questions involving evolving therapies and diagnostics-thus, caution should be used when using a platform like ChatGPT 3.5 to assess use of advanced technology. Patients should be counseled on the importance of consulting their surgeons to receive accurate and up to date recommendations, and use LLM's to augment their understanding of these important health-related topics.

The genetics of dementia.

Over the past decade, there has been a dramatic evolution of genetic methodologies that can be used to identify genes contributing to disease. Initially, the focus was primarily on classical linkage analysis; more recently, genomewide association studies, and high-throughput whole genome and whole exome sequencing have provided efficient approaches to detect common and rare variation contributing to disease risk. Application of these methodologies to dementias has led to the nomination of dozens of causative and susceptibility genes, solidifying the recognition that genetic factors are important contributors to the disease processes. In this review, the authors focus on current knowledge of the genetics of Alzheimer's disease and frontotemporal lobar degeneration. A working understanding of the genes relevant to common dementias will become increasingly critical, as options for genetic testing and eventually gene-specific therapeutics are developed.

Internal jugular vein reconstruction: An algorithm for reconstructive surgeons.

OBJECTIVES: The internal jugular vein (IJV) provides critical drainage from the brain, skull, and deep regions of the face and neck. Compromise to the bilateral IJVs has severe sequelae, but even unilateral IJV sacrifice or thrombosis after treatment can have sequelae. Despite the potential role of IJV reconstruction for head and neck surgeons, information about the indications, technique, and outcomes of the procedure are sparse. PATIENTS AND METHODS: We present a woman who had IJV sacrifice for an oral cavity cancer along with a contralateral selective neck dissection and adjuvant chemoradiation who developed occlusion of the contralateral IJV after her treatment, resulting in unacceptable cervical lymphedema and extensive neck varicosities. An end-to-side bypass from the superior IJV to the ipsilateral external jugular vein was performed. RESULTS: There were no complications from the procedure, which resulted in dissipation of her preoperative symptoms. We describe the literature surrounding IJV reconstruction, considerations for its use, the technique itself, and advice for perioperative management. CONCLUSION: IJV reconstruction is a valuable but underutilized technique for the head and neck microvascular surgeon in cases of bilateral threatened IJV outflow.

Acute Cricoarytenoid Joint Fixation Following Routine Intubation: A Case Report.

Prolonged intubation is a common cause of injury to the posterior larynx often resulting in cricoarytenoid joint (CAJ) fixation and posterior glottic stenosis (PGS). We present a case of respiratory failure due to acute bilateral CAJ fixation and PGS following only 2 days of intubation for routine cardiac surgery. A tracheostomy was placed due to critical airway obstruction. Clinicians should remain vigilant for laryngeal injury presenting as CAJ fixation and PGS. Prompt surgical consultation is advised as early intervention is associated with reduced morbidity.

Neoadjuvant dabrafenib and trametinib for functional organ preservation in recurrent BRAF V600E-mutated papillary thyroid cancer.

OBJECTIVES: To describe the first reported use of neoadjuvant dabrafenib and trametinib specifically to permit organ conservation surgery in locally advanced recurrent differentiated thyroid carcinoma. PATIENTS AND METHODS: A patient presented with locally recurrent, radioiodide-resistant DTC with a BRAF V600E mutation invading the laryngotrachea. Definitive treatment would require a total laryngectomy. She was offered neoadjuvant dabrafenib and trametinib prior to surgery. RESULTS: A significant radiographic response permitted partial laryngectomy, enabling preservation of voice, early resumption of oral feeding, and avoidance of permanent tracheostomy. At 9 months, she remained free of disease. CONCLUSION: Neoadjuvant tyrosine kinase inhibitor treatment prior to definitive surgery for locally-invasive recurrent DTC is a potential approach that may limit the degree of surgery and associated morbidity.

Sponsorship in Otolaryngology-Head and Neck Surgery: A Pathway to Equity, Diversity, and Inclusion.

Importance: Sponsorship, distinct from mentorship or coaching, involves advancing the careers of individuals by nominating them for roles, increasing the visibility of their work, or facilitating opportunities. Sponsorship can open doors and enhance diversity; however, achieving desirable outcomes requires equitable approaches to cultivating potential in sponsees and promoting their success. The evidence on equitable sponsorship practices has not been critically examined, and this special communication reviews the literature, highlighting best practices. Observations: Sponsorship addresses an unmet need for supporting individuals who have historically been afforded fewer, less visible, or less effective opportunities for upward career mobility. Barriers to equitable sponsorship include the paucity of sponsors of underrepresented identity; smaller and underdeveloped networks among these sponsors; lack of transparent, intentional sponsorship processes; and structural inequities that are associated with recruitment, retention, and advancement of diverse individuals. Strategies to enhance equitable sponsorship are cross-functional, building on foundational principles of equity, diversity, and inclusion; patient safety and quality improvement; and insights from education and business. Equity, diversity, and inclusion principles inform training on implicit bias, cross-cultural communication, and intersectional mentoring. Practices inspired by patient safety and quality improvement emphasize continuously improving outreach to diverse candidates. Education and business insights emphasize minimizing cognitive errors, appreciating the bidirectional character of interactions, and ensuring that individuals are prepared for and supported in new roles. Collectively, these principles provide a framework for sponsorship. Persistent knowledge gaps are associated with timing, resources, and systems for sponsorship. Conclusions and Relevance: The nascent literature on sponsorship is limited but draws on best practices from various disciplines and has potential to promote diversity within the profession. Strategies include developing systematic approaches, providing effective training, and supporting a culture of sponsorship. Future research is needed to define best practices for identifying sponsees, cultivating sponsors, tracking outcomes, and fostering longitudinal practices that are sustainable at local, regional, and national levels.

Impact of applicant and program factors on preference signaling outcomes in otolaryngology.

Objectives: To assess the impact of applicant and program characteristics on preference signaling outcomes during the 2021 and 2022 application cycles in otolaryngology. Methods: The Texas Seeking Transparency in Applications to Residency survey was used for otolaryngology applicants during the 2021 and 2022 match years. The primary outcome of interest was signal yield, defined as the number of interviews at signaled programs divided by the total number of signals sent. Associations with applicant-reported characteristics, geographic connections to programs, and program reputation were assessed. Results: On average 59.5% of signals resulted in an interview (signal yield). There was a positive correlation between the number of signals sent to a program with a reported geographic connection and signal yield, with each additional signal resulting in a 3.4% increase in signal yield (p = .03). Signal yield was positively associated with number of publications (p < .001); number of abstracts, posters, and presentations (p = .04); and whether the applicant took a research year (p = .003). Applicants with higher USMLE Step 1 (p = .01) and Step 2 (p = .003) scores, publications (p = .03), volunteer (p = .008) and leadership (p = .001) experiences received a lower percentage of their total interviews from signaled programs whereas applicants from the 3rd (p < .001) and 4th (p = .03) cumulative class ranked quartiles received a higher percentage of their total interviews from signaled programs. Conclusions: Signal yield appears to have a significant association with geographic connections to programs and applicant competitiveness. This study may help applicants, advisors, and programs maximize the benefit of the preference signaling system.Levels of evidence: Level 4.
