Role of the otologist/neurotologist in managing auricular and periauricular cutaneous malignancies: A 10-year otologic oncology experience.

Objective: Auricular/periauricular cutaneous malignancies can be challenging to manage surgically due to the complex anatomy of the region. Otologists/neurotologists have unique skillsets that are well-suited to surgically treat these patients. We aim to highlight the role of otologists and neurotologists in providing surgical care of patients with auricular and periauricular malignancies by describing the experience of a single fellowship-trained neurotologist over a 10-year period. Methods: Retrospective chart review of 387 patients with auricular and periauricular malignancy treated by a single neurotologist between 2012 and 2022 was completed. Tumor histology and procedures performed for each patient were extracted. Additional data was collected for a subset of 84 patients with complex cases requiring selective neck dissection, parotidectomy, lateral temporal bone resection, regional advancement or rotational flap reconstruction, and/or free tissue transfer reconstruction. Results: Within the series of 387 patients, squamous cell carcinoma was the most common histology (42.6%, n = 165), followed by basal cell carcinoma (40.8%, n = 158), and melanoma (9.8%, n = 38). Common surgical procedures included wide local excision (61.8%, n = 239), partial/sub-total auriculectomy 18.3% (n = 71), or total auriculectomy 5.2% (n = 20). Within the 84-patient subset, median age at diagnosis was 71.9 years. Dermatologists provided most patient referrals (50.0%, n = 42). Most common tumor locations included: auricular (58.3%, n = 49), pre-auricular (21.4%, n = 18), and parotid (27.4%, n = 23). Revision surgery occurred in 22.6% of cases (n = 19), of which 26.3% (n = 5) for positive margins and 31.6% (n = 6) for recurrence. Mean follow-up was 22.8 months. Disease-specific 5-year survival was 91%. Conclusions: We demonstrate the feasibility of an otologist/neurotologist incorporating the surgical management of auricular and periauricular malignancies into their practice. Level of Evidence: 4.

Readiness of Medical Students to Care for Diverse Patients: A Validated Assessment of Cross-Cultural Preparedness, Skills, and Curriculum.

Introduction: Effective cross-cultural care is foundational for mitigating health inequities and providing high-quality care to diverse populations. However, medical school teaching practices vary widely, and learners have limited opportunities to develop these critical skills. To understand the current state of cross-cultural education and to identify potential opportunities for improvement, we disseminated a validated survey instrument among medical students at a single institution. Methods: Learners across 4 years of medical school participated in the cross-cultural care assessment, using a tool previously validated with resident physicians and modified for medical students. The survey assessed medical student perspectives on (1) preparedness, (2) skillfulness, and (3) educational curriculum and learning environment. Cross-sectional data were analyzed by class year, comparing trends between school years. Results: Of 700 possible survey responses, we received 260 (37% response rate). Fourth-year students had significantly higher scores than first-year students (p<0.05) for 7 of 12 preparedness items and 4 of 9 skillfulness items. Less than 50% of students indicated readiness to deliver cross-cultural care by their fourth year in 9 of 12 preparedness items and 6 of 9 skillfulness items. Respondents identified inadequate cross-cultural education as the primary barrier. Discussion: Medical students reported a lack of readiness to provide cross-cultural care, with self-assessed deficiencies persisting through the fourth year of medical school. Medical educators can use data from the cross-cultural care survey to longitudinally assess students and enhance curricular exposures where deficiencies exist. Optimizing cross-cultural education has the potential to improve the learning environment and overall patient care.

Verrucous Carcinoma of the Foot: A Retrospective Study of 19 Cases and Analysis of Prognostic Factors Influencing Recurrence.

This study sought to evaluate a cohort of patients with verrucous carcinoma of the foot with special focus on 5 cases of locally recurrent tumors despite negative margins. Nineteen cases of verrucous carcinoma of the foot were identified through the University of Michigan (Ann Arbor, Michigan) pathology database from 1995 to 2019 and were included in demographic and clinical presentation analyses. Sixteen cases were treated at the University of Michigan and are included in the treatment analyses. A review of medical records was conducted to characterize clinical, surgical, and pathologic features. Recurrent cases were found to have a predilection for nonglabrous skin of the foot and great toe. Otherwise, there was little to differentiate outcomes between recurrent and nonrecurrent groups based on demographic, clinical, surgical, or histopathologic data. Recurrent tumors regrew locally and were not associated with histologic progression to conventional squamous cell carcinoma. Verrucous carcinoma of the nonglabrous surface of the foot should have a higher suspicion for possible local recurrence. Recurrence occurs within months of treatment, deserves early biopsy, and warrants aggressive re-treatment. Future directions should include greater examination of pathologic features and genetic markers to improve management of verrucous carcinoma of the foot.

Effects of Moringa Extract on Aminoglycoside-Induced Hair Cell Death and Organ of Corti Damage.

HYPOTHESIS: Moringa extract, a naturally occurring anti-oxidant, protects against aminoglycoside-induced hair cell death and hearing loss within the organ of Corti. BACKGROUND: Reactive oxygen species (ROS) arise primarily in the mitochondria and have been implicated in aminoglycoside-induced ototoxicity. Mitochondrial dysfunction results in loss of membrane potential, release of caspases, and cell apoptosis. Moringa extract has not previously been examined as a protective agent for aminoglycoside-induced ototoxicity. METHODS: Putative otoprotective effects of moringa extract were investigated in an organotypic model using murine organ of Corti explants subjected to gentamicin-induced ototoxicity. Assays evaluated hair cell loss, cytochrome oxidase expression, mitochondrial membrane potential integrity, and caspase activity. RESULTS: In vitro application of moringa conferred significant protection from gentamicin-induced hair cell loss at dosages from 25 to 300 µg/mL, with dosages above 100 µg/mL conferring near complete protection. Assays demonstrated moringa extract suppression of ROS, preservation of cytochrome oxidase activity, and reduction in caspase production. CONCLUSION: Moringa extract demonstrated potent antioxidant properties with significant protection against gentamicin ototoxicity in cochlear explants.

The Clarion Call of the COVID-19 Pandemic: How Medical Education Can Mitigate Racial and Ethnic Disparities.

Public health crises palpably demonstrate how social determinants of health have led to disparate health outcomes. The staggering mortality rates among African Americans, Native Americans, and Latinx Americans during the COVID-19 pandemic have revealed how recalcitrant structural inequities can exacerbate disparities and render not just individuals but whole communities acutely vulnerable. While medical curricula that educate students about disparities are vital in rousing awareness, it is experience that is most likely to instill passion for change. The authors first consider the roots of health care disparities in relation to the current pandemic. Then, they examine the importance of salient learning experiences that may inspire a commitment to championing social justice. Experiences in diverse communities can imbue medical students with a desire for lifelong learning and advocacy. The authors introduce a 3-pillar framework that consists of trust building, structural competency, and cultural humility. They discuss how these pillars should underpin educational efforts to improve social determinants of health. Effecting systemic change requires passion and resolve; therefore, perseverance in such efforts is predicated on learners caring about the structural inequities in housing, education, economic stability, and neighborhoods-all of which influence the health of individuals and communities.

Sudden Sensorineural Hearing Loss: A Diagnostic and Therapeutic Emergency.

The family physician's role in recognizing and managing sudden sensorineural hearing loss (SSNHL) is crucial. A recently updated otolaryngologic clinical practice guideline has been released for this emergency syndrome, but dissemination is limited to a specialty journal. As a result, the guidelines may not be widely available in the primary care setting where patients often present. We provide this focused review to clarify and disseminate SSNHL guidelines for the frontline family physician.

Head and Neck Reconstruction in the Vessel Depleted Neck.

Microvascular free tissue transfer has revolutionized reconstruction and subsequently functional outcomes in the head and neck, but requires suitable recipient vessels for successful results. Recipient vessels can be significantly compromised by prior surgery, radiation therapy, or existing and/or underlying vascular disease in the neck. When further microvascular reconstruction is required in the vessel-depleted neck, identification of appropriate vessels for anastomosis can be difficult and can present complex decisions for the surgeon as well as the patient. In this article, we review the available literature on the vessel depleted neck and the possible vessel options. We present critical strategies for preoperative treatment planning and vessel selection in these patients. We also discuss the benefits and limitations of arterial and venous options while commenting on our unique institution's experiences. The external carotid branches as well as the available subclavian artery branches are presented in detail. The venous anatomy is also described, with particular focus on the accompanying veins and cephalic vein. We provide guidance on the selection and modification of free flaps to achieve the greatest function and cosmetic outcomes in the vessel depleted neck. Our collection of advanced management techniques will provide surgeons with more options to manage the complexity of the vessel depleted neck, and to further help patients understand the risk and benefits of these selections.

Airway Management for Endoscopic Laryngotracheal Stenosis Surgery During COVID-19.

The novel coronavirus disease 2019 (COVID-19) pandemic presents unique challenges for surgical management of laryngotracheal stenosis. High viral concentrations in the upper aerodigestive tract, the ability of the virus to be transmitted by asymptomatic carriers and through aerosols, and the need for open airway access during laryngotracheal surgery create a high-risk situation for airway surgeons, anesthesiologists, and operating room personnel. While some surgical cases of laryngotracheal stenosis may be deferred, patients with significant airway obstruction or progressing symptoms often require urgent surgical intervention. We present best practices from our institutional experience for surgical management of laryngotracheal stenosis during this pandemic, including preoperative triage, intraoperative airway management, and personal protective measures.
