ABSTRACTImportanceHighlighting the global disparities in otolaryngology training and, ultimately, service delivery, emphasizing the need for equitable access to training resources and programs.ObjectiveTo describe the relationship between the quality, content, and location of otolaryngology–head and neck surgery training and education and the resulting impact on the delivery of otolaryngology care globally.DesignAn online cross‐sectional survey to otolaryngologists, gathering information on their training and education experiences, and factors influencing their choice of training location and practice.SettingThe online survey was available in multiple languages, distributed via national and international professional otolaryngology societies, snowballing and social media.ParticipantsThe respondents were practicing otolaryngologists representing all seven World Health Organization regions.ExposuresWorld Bank income groups classification.Main Outcomes and MeasuresOur expected outcome was that subspecialty training and access to educational resources were significantly readily available to respondents from high‐income countries, leading to more confidence in performing complex procedures post training.ResultsA total of 91 participants were included in the analysis, with 47 (52%) practicing in high‐income countries and 44 (48%) in low‐ and middle‐income countries. Sixty‐one participants (67%) were male. Subspecialty training and access to educational resources were significantly less available in low‐ and middle‐income countries, leading to lower confidence among low‐ and middle‐income countries physicians in performing complex procedures. High‐income country respondents reported better access to diverse training resources and felt more prepared for a broader range of procedures.Conclusion and RelevanceSignificant disparities exist in OHNS training resources and subspecialty training opportunities between high‐ and low‐middle‐income countries. There is a critical need to integrate complementary training and educational modalities into local systems. Addressing the shortage of educational resources and promoting open‐access initiatives in low‐middle‐income countries are essential steps toward enhancing surgical education and improving global otolaryngology healthcare outcomes.

ABSTRACT Objective Availability of surgical equipment and access to essential clinical services remains an important barrier to surgical care delivery, particularly in low‐ and middle‐income countries (LMICs). This study aims to characterize the relative availability of essential equipment for otolaryngology‐head and neck surgery (OHNS) care across World Bank income groups. Methods We conducted a cross‐sectional survey on otolaryngologists' perceptions on the availability of surgical equipment and ancillary services in their respective practice settings per a 5‐point Likert scale ranging from never to always available. The study was disseminated online via professional societies, personal contacts, and social media. Eligible participants included otolaryngologists from 194 WHO‐recognized countries, which were grouped by World Bank income group classification and WHO region. Results The study involved 146 otolaryngologists, 69 (47%) from high‐income countries (HICs), and 77 (53%) from LMICs. LMIC respondents were predominantly from the African and South‐East Asian regions, which comprised 48% and 7.8% of all LMIC respondents, respectively. Results revealed significant differences in the availability of otologic, rhinologic, and endoscopic airway equipment between HICs and LMICs. Differences existed among commonly used equipment such as tympanomastoidectomy equipment and rigid bronchoscopy, to subspecialized equipment such as functional endoscopic sinus surgery equipment and cochlear implants ( p < 0.05 each). Conclusions The study highlighted key disparities in the availability of essential equipment for baseline OHNS care, especially for pediatric airway and otologic conditions. These results can be used to guide investment and advocacy efforts to improve specialty‐specific surgical infrastructure relative to the global burden of OHNS diseases in low‐resource settings.

AbstractThis study compares delays in otolaryngologic care between patients in Mekelle, Ethiopia and Harare, Zimbabwe using the Three Delays model. Patient surveys conducted among 46 patients in Zimbabwe during October 2022 and 105 patients in Ethiopia during June 2023 revealed a significantly higher prevalence of delays in seeking and reaching care in Ethiopia. This was in the aftermath of the Tigray War, which damaged the region's health care infrastructure and diminished the trust of patients. In Zimbabwe, there was poor awareness among patients and nonotolaryngologist providers of otolaryngology disease and care capacity leading to delays in seeking and reaching care. Patients in both countries faced delays in receiving appropriate care due to resource limitations, with Ethiopia's constraints worsened by the recent war and Zimbabwe's by consistent health care underfunding. The longest delays were observed in head and neck oncology care. These findings provide a foundation for understanding otolaryngologic care delays in these low‐ and middle‐income countries.

AbstractObjective(s)To evaluate the otolaryngology surgical capacity in Harare, Zimbabwe by analyzing procedural volumes across four hospitals, one private and three public, from 2019 to 2022.MethodsA retrospective review of hand‐written surgical case logs was conducted at Harare Eye, Ear, Nose, and Throat Institute (HEENT), Parirenyatwa Group of Hospitals (PGH), Sally Mugabe Children's Hospital (SMCH), and Sally Mugabe Adult's Hospital (SMAH). Patient age and surgical intervention for all otolaryngology surgeries performed in the operating room from 2019 to 2022 were recorded. Procedures were categorized into six groups: head and neck malignancy, laryngeal surgery, oropharyngeal surgery, otologic surgery, rhinology/sinus surgery, and other. Data were analyzed using descriptive statistics to identify trends in surgical volume and types of procedures across hospitals.ResultsA total of 2626 procedures were recorded: 1470 at HEENT, 377 at PGH, 625 at SMCH, and 154 at SMAH. Of these, 39.5% were performed on pediatric patients and 60.5% on adult patients. The most common procedures were adenotonsillectomy/adenoidectomy/tonsillectomy (38.9%), diagnostic endoscopies (10.4%), and endoscopic sinus surgery (8.3%). HEENT performed the highest volume and widest range of procedures. HEENT had higher surgical volumes across all groups of procedure, except for laryngeal surgery.ConclusionThis study found disparities in otolaryngology surgical capacity between a private hospital, HEENT, and three public tertiary hospitals—SMCH, SMAH, and PGH, the largest hospital in the country—in Harare, Zimbabwe. Additionally, it highlights areas for targeted interventions in capacity building. This study establishes a foundation for understanding otolaryngologic surgical capacity in the country, supporting international collaboration, guiding future research, and serving as a model for similar assessments in other LMICs.Level of evidenceLevel VI.

Introduction: External ear malformations represent a spectrum of congenital anomalies that may involve the external auditory canal (EAC), tympanic membrane (TM), or associated structures. A rare anomaly, the EAC skin wedge, results from incomplete canalization during embryologic development. This report presents the clinical presentation, diagnostic evaluation, and surgical management of this condition. Objective: To detail the successful surgical management of an isolated EAC skin wedge and demonstrate the applicability of argon laser in treating these congenital anomalies. Methods: A 13-month-old female presented with recurrent otitis media and mild bilateral conductive hearing loss. Physical examination revealed a fan-like skin wedge spanning the EAC to the TM. Imaging with temporal bone computed tomography confirmed the extent of the anomaly. Under general anesthesia, the skin wedge was ablated using an argon laser, followed by antibiotic-soaked packing to prevent scarring and recurrence. Follow-up audiometry and endoscopic evaluations assessed outcomes. Results: The procedure was well-tolerated, with no intraoperative complications. At 3 weeks and 3 months postoperatively, no recurrence of the skin wedge was observed, and audiometry normalized. The patient demonstrated improved middle ear ventilation and resolution of conductive hearing loss. Conclusions: This case demonstrates the successful use of argon laser in the management of a rare congenital EAC anomaly. Argon lasers offer precise ablation and excellent hemostasis, making them a valuable option for similar cases. This report emphasizes the importance of tailored surgical approaches for rare pediatric ear malformations.

Introduction: Laryngotracheoesophageal clefts (LTEC) are well-known aspiration-associated lesions. Results of swallow studies, and respiratory, feeding, and swallowing symptoms are commonly used indications for repair, despite being unclear predictors of disease. Although lung inflammation and injury are primary concerns, such findings are uncommonly and inconsistently evaluated and reported and therefore it remains unclear how well swallow studies predict lung disease. Methods: Children seen in our Aerodigestive program 10/1/2012 and 9/30/2023, with a LTEC and a videofluoroscopic swallow study (VFSS) or flexible endoscopic evaluation of swallowing (FEES) were included. Data regarding clinical history and risk factors, BAL, chest CT, and impedance probe results were abstracted, along with VFSS/FEES results and functional oral intake scale (FOIS-P/I) at baseline and follow-up. Results: 82 subjects identified. Lung inflammation and bronchiectasis were common and correlated. Clinical factors, impedance probe, and the presence/severity of swallowing abnormalities on VFSS/FEES were not predictive of lung disease. 57 patients underwent LTEC repair for a range of indications, only 49% based on CT and/or BAL findings. LTEC repair was associated with a trend towards improvement feeding and swallowing, yet none of these met statistical significance. Discussion: Children with LTEC have a high prevalence of inflammatory lung disease and injury and undergo repair for a variety of reasons. The insufficient ability of swallow study to identify patients with lung disease suggests that such studies identify functional abnormalities but not a disease state, per se. Nevertheless, LTEC repair is associated with improvements in feeding and swallowing in a subset of patients.

AbstractObjectiveThis study aims to document and analyze the challenges and outcomes of performing complex airway surgery in a low‐resource, post‐war setting in Mekelle, Ethiopia.MethodsThis prospective case series examines clinical data from five patients who underwent airway reconstruction surgeries and one patient who underwent total laryngectomy at Ayder Comprehensive Specialized Hospital in Mekelle. Data included patient demographics, airway stenosis etiology and severity, operative details, postoperative outcomes, complications, and hospital length of stay. Ethical approval was obtained from institutional review boards at Mayo Clinic and Mekelle University.ResultsThe study included six patients aged 9–62 years, with surgeries comprising three cricotracheal resections, two tracheal resections, and one laryngectomy. Three reconstructions were for war‐related injuries. Challenges included power outages during surgeries, limitations in medical supplies and equipment, and inadequate perioperative care. Despite these, three patients requiring tracheostomies were successfully decannulated within a year. However, complications such as restenosis, infections, and the need for reintubation were common.ConclusionAirway surgeries in a low‐resource, post‐war setting face significant hurdles, including perioperative care quality, resource limitations, and infrastructure issues. Successful outcomes require multidisciplinary training tailored to local contexts, investments in hospital infrastructure and reliable electricity, and proper perioperative nutrition. This study highlights the need for comprehensive interventions to improve surgical care in such settings.Level of evidence: IV.

Abstract Objective Intracranial complications of pediatric sinusitis are uncommon but are often associated with significant morbidity, especially when appropriate care is delayed. The present study aimed to identify commonalities for the development and progression of these complications in the pediatric population. Data Sources CENTRAL, CINAHL, Citation searching, ClinicalTrials.gov , Embase, Google Scholar, MEDLINE, PsycINFO, PubMed, Scopus, Web of Science, and World Health Organization. Review Methods A comprehensive literature search was performed using Preferred Reporting Items for Systematic Reviews and Meta‐analyses scoping review guidelines. Studies describing intracranial infections secondary to sinusitis in the pediatric population (age <18 years) were included. Studies in which adult and pediatric data were not separated and studies in which the pediatric cohort was fewer than 10 cases were excluded. Ultimately, 33 studies describing 1149 unique patient cases were included for data collection and analysis. Results Our analysis revealed intracranial complications were more common in adolescent males. Most children presented with over 1 week of vague symptoms, such as headache and fever. The majority of complications were diagnosed radiographically with computed tomography. Subdural empyema and epidural abscess were the most common intracranial complications reported. On average, patients were admitted for over 2 weeks. Most children were treated with a combination of antibiotics and surgical intervention. Complications were rare, but when present, were often associated with significant morbidity. Conclusion This scoping review of the available literature has provided insight into commonalities among pediatric patients who develop intracranial complications of sinusitis, providing a foundation for further study to inform medical and surgical decision‐making in this population.

AbstractObjectivesTo describe findings from an otolaryngology‐specific needs assessment tool in Zimbabwe.MethodsSurveys were developed and shared with Low‐Middle Income Country (LMIC) hosting institutions in Zimbabwe and to High‐Income Country surgical trip participants (HIC). Respondents were otolaryngologists identified online and through professional networks who had participated in a surgical trip.ResultsThe most common procedures Zimbabwe otolaryngologists reported treating were adenotonsillectomy (85.7%), chronic rhinosinusitis (71.4%), chronic otitis (57.1%), and head and neck tumor intervention (57.1%). The most common untreatable conditions that host physicians wanted to treat were skull base surgery (71.4%), flap reconstructions (57.1%), and laryngotracheal reconstruction (57.1%). The largest discrepancy between host desires and visiting team offerings were flap reconstruction (57.1%), nasal bone deformities (37.1%), and laryngotracheal reconstruction (17.1%). Perceptions of short‐term surgical trips (STST) were recorded for host and visiting teams, and important differences between the public and private sectors of care in Zimbabwe were also identified.ConclusionThe surveys utilized in this study served as a bidirectional needs assessment of the requirements and care goals of host institutions and visiting teams in Zimbabwe. Differences between public and private sectors of care, particularly regarding infrastructure, resources, and surgical goals, were revealed, and the results can be utilized as part of efforts to maximize efforts within global surgical partnerships.Level of EvidenceVI.
