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.

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.

Sub-Saharan Africa (SSA), home to over 1 billion people, has only one paediatric otolaryngology fellowship program and nine fellowship-trained paediatric Otolaryngology Head and Neck Surgery (OHNS) specialists covering seven countries. Seven of these specialists estimated an average of 40+ patients per month are in need of critical surgical airway management in their respective countries and that 2–25 deaths per year (mainly paediatric) occur in their country from lack of access to foreign body removal equipment. Investing in paediatric airway infrastructure and capacity would largely benefit the health system in SSA, where the current lack of equipment alone leads to unmeasured morbidity and mortality. As a region of the world with the largest paediatric populations, sub-Saharan Africa’s need is all the more pressing given the disproportionately low number of medical specialists, institutions and resources. Collaborative approaches in procurement and maintenance of high-quality, cost-effective equipment are crucially desirable factors in both low- and middle-income countries (LMICs) and high-income countries (HICs). We, as the Global OHNS Initiative, urge for multi-stakeholder engagement and collaboration to forge lasting change.

Introduction: Differential diagnoses of a pediatric neck mass are extensive, ranging across benign, malignant, congenital and infectious causes. Limited access to imaging in low-resource settings increases the complexity of narrowing this list to appropriately diagnose and treat neck masses. This occasionally allows neck masses to grow unchecked, increasing the morbidity of their presence and eventual excision. The goal of this report is to describe nuances in the diagnosis and treatment of pediatric neck masses in resource-limited settings through a case report of a neck mass in a pediatric patient. Patient presentation: A 10-year-old girl in Harare, Zimbabwe, presented for surgical management of a midline neck mass that appeared 4 years prior to presentation for definitive treatment. A myriad of barriers delayed her care, allowing the mass to grow into her floor of mouth, displacing her tongue and leading to speech and feeding difficulties. Management and outcome: At presentation to the tertiary care facility, she received a pre-operative ultrasound showing a well-circumscribed, echogenic mass. Her neck mass was surgically excised through a transoral approach. Permanent pathology was consistent with a dermoid cyst. Conclusion: At 1-month postoperative follow-up, the patient had experienced no complications and had a complete resolution of her functional symptoms and appearance. Contribution: We present a case that can illuminate the utility of ultrasound in the diagnosis of pediatric neck masses. Additionally, we facilitate an important discussion on transoral versus transcervical approach for midline neck masses with the decision hinging on size, location, surgeon preference and comfort and consideration of cosmesis.
