ABSTRACT

Importance: A core component of delivering care of head and neck diseases is an adequate workforce. The World Health Organization report, Multi-Country Assessment of National Capacity to Provide Hearing Care, captured primary workforce estimates from 68 member states in 2012, noting that response rates were a limitation and that updated more comprehensive data are needed. Objective: To establish comprehensive workforce metrics for global otolaryngology-head and neck surgery (OHNS) with updated data from more countries/territories. Design, Setting, and Participants: A cross-sectional electronic survey characterizing the OHNS workforce was disseminated from February 10 to June 22, 2022, to professional society leaders, medical licensing boards, public health officials, and practicing OHNS clinicians. Main Outcome: The OHNS workforce per capita, stratified by income and region. Results: Responses were collected from 121 of 195 countries/territories (62%). Survey responses specifically reported on OHNS workforce from 114 countries/territories representing 84% of the world's population. The global OHNS clinician density was 2.19 (range, 0-61.7) OHNS clinicians per 100 000 population. The OHNS clinician density varied by World Bank income group with higher-income countries associated with a higher density of clinicians. Regionally, Europe had the highest clinician density (5.70 clinicians per 100 000 population) whereas Africa (0.18 clinicians per 100 000 population) and Southeast Asia (1.12 clinicians per 100 000 population) had the lowest. The OHNS clinicians deliver most of the surgical management of ear diseases and hearing care, rhinologic and sinus diseases, laryngeal disorders, and upper aerodigestive mucosal cancer globally. Conclusion and Relevance: This cross-sectional survey study provides a comprehensive assessment of the global OHNS workforce. These results can guide focused investment in training and policy development to address disparities in the availability of OHNS clinicians.

ABSTRACT

PURPOSE OF REVIEW: Open access articles are more frequently read and cited, and hence promote access to knowledge and new advances in healthcare. Unaffordability of open access article processing charges (APCs) may create a barrier to sharing research. We set out to assess the affordability of APCs and impact on publishing for otolaryngology trainees and otolaryngologists in low-income and middle-income countries (LMICs). RECENT FINDINGS: A cross-sectional online survey was conducted among otolaryngology trainees and otolaryngologists in LMICs globally. Seventy-nine participants from 21 LMICs participated in the study, with the majority from lower middle-income status (66%). Fifty-four percent were otolaryngology lecturers while 30% were trainees. Eighty-seven percent of participants received a gross monthly salary of less than USD 1500. Fifty-two percent of trainees did not receive a salary. Ninety-one percent and 96% of all study participants believed APCs limit publication in open access journals and influence choice of journal for publication, respectively. Eighty percent and 95% believed APCs hinder career progression and impede sharing of research that influences patient care, respectively. SUMMARY: APCs are unaffordable for LMIC otolaryngology researchers, hinder career progression and inhibit the dissemination of LMIC-specific research that can improve patient care. Novel models should be developed to support open access publishing in LMICs.

ABSTRACT

PURPOSE: The proportion of head and neck cancers (HNCs) with human papillomavirus (HPV) positivity in sub-Saharan Africa (SSA) is poorly characterized. Characterizing this has implications in staging, prognosis, resource allocation, and vaccination policies. This study aims to determine the proportion of HPV-associated HNC in SSA. MATERIALS AND METHODS: This systematic review included searches from PubMed, EMBASE, Web of Science, African Index Medicus, Google Scholar, and African Journals Online. All English publications reporting the proportion of HNC specimens from SSA patients who tested positive for HPV and/or p16 were included. Study quality was assessed using the National Institutes of Health Quality Assessment Tool for Case Series Studies. RESULTS: In this systematic review of 31 studies and 3,850 patients, the overall p16 positivity was 13.6% (41 of 1,037 patients tested) with the highest proportion among oropharyngeal cancers (20.3%, 78 of 384 patients) and the overall HPV polymerase chain reaction positivity was 15.3% (542 of 3,548 samples tested) with the highest proportion among nasopharyngeal cancers (16.5%, 23 of 139 patients). Among the 369 HPV strains detected, the most common genotypes were HPV 16 (226 patients, 59.2%) and HPV 18 (78, 20.4%). CONCLUSION: HPV was found to be associated with a significant proportion of HNC in SSA. The genotypes reported suggest that the nine-valent vaccine and gender-neutral vaccination policies should be considered. Given that these studies may not accurately capture prevalence nor causation of HPV in HNC subsites, additional research is needed to provide a more thorough epidemiologic understanding of HPV-associated HNC in SSA, including risk factors and clinical outcomes.

ABSTRACT

BACKGROUND: To analyze worldwide practices regarding the initiation of oral feeding after total laryngectomy (TL). METHODS: Online survey. RESULTS: Among the 332 responses received, 278 from 59 countries were analyzed. Our results showed that 45.6% of respondents started water and 45.1% started liquid diet between postoperative days 7 and 10. Semi-solid feeds were initiated between days 10 and 14 for 44.9% of respondents and a free diet was allowed after day 15 for 60.8% of respondents. This timing was significantly delayed in cases of laryngo-pharyngectomy and after prior radiotherapy (p < 0.001). A greater proportion of respondents in Africa and Oceania allowed early oral feeding before day 6 as compared with the rest of the world (p < 0.001). CONCLUSION: Despite increasing number of publications, there is still a lack of evidence to support early oral feeding. The majority of respondents preferred to delay its initiation until at least 7 days after surgery.

ABSTRACT

INTRODUCTION: Despite multiple prognostic indicators described for oral cavity squamous cell carcinoma (OCSCC), its management still continues to be a matter of debate. Machine learning is a subset of artificial intelligence that enables computers to learn from historical data, gather insights, and make predictions about new data using the model learned. Therefore, it can be a potential tool in the field of head and neck cancer. METHODS: We conducted a systematic review. RESULTS: A total of 81 manuscripts were revised, and 46 studies met the inclusion criteria. Of these, 38 were excluded for the following reasons: use of a classical statistical method (N = 16), nonspecific for OCSCC (N = 15), and not being related to OCSCC survival (N = 7). In total, 8 studies were included in the final analysis. CONCLUSIONS: ML has the potential to significantly advance research in the field of OCSCC. Advantages are related to the use and training of ML models because of their capability to continue training continuously when more data become available. Future ML research will allow us to improve and democratize the application of algorithms to improve the prediction of cancer prognosis and its management worldwide.

ABSTRACT

BACKGROUND: Head and neck cancer occurs predominantly in the Developing World, with significant challenges relating to a high burden of disease, late presentation, and poor access to curative and palliative care. AIMS: This article describes challenges relating to head and neck cancer care in Sub-Saharan Africa. MATERIAL & METHODS: Educational and training innovations that have been undertaken to improve access to cancer care are presented under the following headings: Open Access Educational Resources African Head and Neck Society (AfHNS); African head and neck surgery fellowship training; AfHNS Virtual Tumor Board; The AfHNS Clinical Practice Guidelines for Head & Neck Cancers in Developing Countries and Limited Resource Settings. Concerns are also raised about universally applicable cancer staging systems. RESULTS: The challenges facing African patients apply to equally to many other parts of the developing world. DISCUSSION: The challenges facing African patients apply to equally to many other parts of the developing world. CONCLUSIONS: For outcomes of head and neck cancers to be improved globally, a far greater investment needs to be made in education and training to improve access to care in developing countries. To make a meaningful global impact on morbidity and mortality related to HNC, clinicians, academic institutions and professional societies in developed countries need to be sensitive to these developing world challenges and should directly engage in improving access to care through promoting open access educational resources, offering specialist and fellowship training, collaborating with appropriate research, and establishing and strengthening centers of excellence in developing countries. LEVEL OF EVIDENCE: 2c "Outcomes research".

ABSTRACT

Equitable research collaborations benefit the quality and relevance of global otolaryngology-head and neck surgery research. However, analyses of existing global health literature have shown disproportionate representation by foreign authors. To avert this inequity and improve global otolaryngology-head and neck surgery research, we propose a framework that emphasizes local representation and capacity building in research.

ABSTRACT

BACKGROUND: Head and neck cancers occur predominantly in developing countries where access to care is poor. Sub-Saharan Africa has <20 head and neck surgeons for >1 billion people and has only two fellowship training programs. METHODS AND RESULTS: The AfHNS Head and Neck Fellowship is being introduced to accelerate training of African surgeons to improve access to resource appropriate cancer care. By avoiding fixed time-in-training and single training sites, training can be offered at multiple centers in Africa, even with lower patient volumes. It also creates opportunities for accredited international surgical outreach programs to contribute to training. CONCLUSIONS: Having prescribed reading and appropriate Entrustable Professional Activities that are assessed through Workplace Based Assessment, and having a summative virtual oral examination ensures that fellows are fit-for-purpose to practice in an African resource-constrained setting. Other developing countries are encouraged to adopt a similar approach to expanding head and neck cancer services.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Primary sarcomas in the head and neck region are rare. Inflammatory leiomyosarcoma was first described in 1995. The case reported herein is the first reported inflammatory leiomyosarcoma occurring in the head and neck. PRESENTATION OF CASE: A 37-year-old male presented with a long history of an asymptomatic slowly enlarging neck mass. Examination revealed a firm mass in the lower third of the right sternocleidomastoid muscle. Computerized tomography and magnetic resonance imaging showed a lobulated, well-circumscribed tumour with malignant features. A wide local excision was performed and histopathological examination confirmed an inflammatory leiomyosarcoma. DISCUSSION: Inflammatory leiomyosarcoma is a recently described peculiar soft tissue tumour with histological features overlapping conventional leiomyosarcoma, and dense lymphocytic inflammation and immunohistochemical reactivity for both smooth and skeletal muscle markers. These are indolent tumours and wide local excision is curative. CONCLUSION: This case highlights the importance of considering primary sarcomas in the differential diagnosis of asymptomatic head and neck masses.

ABSTRACT

The overwhelming majority of head and neck cancers and related deaths occur in low- and middle-income countries, which have challenges related to burden of disease versus access to care. Yet the additional health care burden of the COVID-19 pandemic has also impacted access to care for patients with head and neck cancer in the United States. This article focuses on challenges and innovation in prioritizing head and neck cancer care in Sub-Saharan Africa, the Indian experience of value-added head and neck cancer care in busy and densely populated regions, and strategies to optimize the management of head and neck cancer in the United States during the COVID-19 pandemic.

ABSTRACT

PURPOSE: The rapid spread of the SARS-CoV-2 pandemic around the world caused most healthcare services to turn substantial attention to treatment of these patients and also to alter the structure of healthcare systems to address an infectious disease. As a result, many cancer patients had their treatment deferred during the pandemic, increasing the time-to-treatment initiation, the number of untreated patients (which will alter the dynamics of healthcare delivery in the post-pandemic era) and increasing their risk of death. Hence, we analyzed the impact on global cancer mortality considering the decline in oncology care during the COVID-19 outbreak using head and neck cancer, a known time-dependent disease, as a model. METHODS: An online practical tool capable of predicting the risk of cancer patients dying due to the COVID-19 outbreak and also useful for mitigation strategies after the peak of the pandemic has been developed, based on a mathematical model. The scenarios were estimated by information of 15 oncological services worldwide, given a perspective from the five continents and also some simulations were conducted at world demographic data. RESULTS: The model demonstrates that the more that cancer care was maintained during the outbreak and also the more it is increased during the mitigation period, the shorter will be the recovery, lessening the additional risk of dying due to time-to-treatment initiation. CONCLUSIONS: This impact of COVID-19 pandemic on cancer patients is inevitable, but it is possible to minimize it with an effort measured by the proposed model.

ABSTRACT

OBJECTIVES/HYPOTHESIS: Otolaryngology instructional videos available online are often of poor quality. The objective of this article was to establish international consensus recommendations for the production of educational surgical videos in otolaryngology. STUDY DESIGN: DELPHI survey. METHODS: Twenty-seven international respondents participated in this study from 12 countries. Consensus was reached after three rounds of questionnaires following the Delphi methodology. The proposals having reached the 80% agreement threshold in the third round were retained. RESULTS: The main recommendations are as follows: 1) Ethics: patients must be anonymized and unrecognizable (apart from plastic surgery if necessary). A signed authorization must be obtained if the person is recognizable. 2) Technical aspects: videos should be edited and in high-definition (HD) quality if possible. Narration or subtitles and didactic illustrations are recommended. 3) Case presentation: name of pathology and procedure must be specified; the case should be presented with relevant workup. 4) Surgery: surgical procedures should be divided into several distinct stages and include tips and pitfalls. Pathology should be shown if relevant. Key points should be detailed at the end of the procedure. 5) Organ-specific: type of approach and bilateral audiometry should be specified in otology. Coronal plane computed tomography scans should be shown in endonasal surgery. It is recommended to show pre- and postoperative videos in voice surgery and preoperative drawings and photos of scars in plastic surgery, as well as the ventilation method in airway surgery. CONCLUSIONS: International recommendations have been determined to assist in the creation and standardization of educational surgical videos in otolaryngology and head and neck surgery.

ABSTRACT

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic has led to a global surge in critically ill patients requiring invasive mechanical ventilation, some of whom may benefit from tracheostomy. Decisions on if, when, and how to perform tracheostomy in patients with COVID-19 have major implications for patients, clinicians, and hospitals. We investigated the tracheostomy protocols and practices that institutions around the world have put into place in response to the COVID-19 pandemic. DATA SOURCES: Protocols for tracheostomy in patients with severe acute respiratory syndrome coronavirus 2 infection from individual institutions (n = 59) were obtained from the United States and 25 other countries, including data from several low- and middle-income countries, 23 published or society-endorsed protocols, and 36 institutional protocols. REVIEW METHODS: The comparative document analysis involved cross-sectional review of institutional protocols and practices. Data sources were analyzed for timing of tracheostomy, contraindications, preoperative testing, personal protective equipment (PPE), surgical technique, and postoperative management. CONCLUSIONS: Timing of tracheostomy varied from 3 to >21 days, with over 90% of protocols recommending 14 days of intubation prior to tracheostomy. Most protocols advocate delaying tracheostomy until COVID-19 testing was negative. All protocols involved use of N95 or higher PPE. Both open and percutaneous techniques were reported. Timing of tracheostomy changes ranged from 5 to >30 days postoperatively, sometimes contingent on negative COVID-19 test results. IMPLICATIONS FOR PRACTICE: Wide variation exists in tracheostomy protocols, reflecting geographical variation, different resource constraints, and limited data to drive evidence-based care standards. Findings presented herein may provide reference points and a framework for evolving care standards.

ABSTRACT

INTRODUCTION: The Breatheasy© Tracheostomy Program based at the Red Cross War Memorial Children's Hospital, Cape Town, manages children mostly from poor socio-economic backgrounds. In our resource-limited setting, it is unclear how these families cope with the demands of a tracheostomised child. We aim to assess the quality of life (QOL) of tracheostomised children and their families as the first study of its kind in a low-resource setting. METHODS: A descriptive, observational study was done to assess the QOL of tracheostomised children managed by the Breatheasy© Program over 10 months. Children with tracheostomies for longer than 6 months, complex syndromic children, and home ventilated children were included. The validated Paediatric Tracheotomy Health Status Instrument (PTHSI) was utilised, where a higher score implied a better outcome. RESULTS: A total of 68 families were recruited. In 57 (85.1%) of the carers, the highest level of education achieved was primary or high school. Twenty-seven (42%) families reported having an annual household income of less than $675 US Dollars (

ABSTRACT

BACKGROUND: Sub-Saharan Africa (SSA) has a shortage of surgeon specialists. Many SSA countries lack specialty training programs but South Africa, an upper middle-income country, has several post-graduate surgical training programs. The primary objective of this study was to describe the retention rates of non-South African SSA surgical trainees from the University of Cape Town (UCT) on the African sub-continent. The secondary objective was to describe advantages and disadvantages of foreign surgical trainees on the UCT surgical training programs. METHODS: This was a two-part cross-sectional survey administered via email between June 1, 2018 and March 1, 2019 to UCT 1) surgical residents and fellows who graduated between 2007 and 2017 and whose country of origin was in SSA but outside South Africa, and 2) UCT surgical division heads. RESULTS: Thirty out of 78 (38%) trainees responded; 83% (n = 25) were male. There was a 96% retention rate of surgical trainees in SSA, 80% (n = 24) returned to their country of origin after training, 83% (n = 25) worked in the public sector, and 90% (n = 27) in teaching hospitals. Seven out of ten surgical division heads responded. Reported advantages of SSA trainees included more junior staff (n = 5, 71%) and the establishment of SSA networks (n = 4, 57%). Disadvantages included increased training responsibilities for educators (n = 2, 29%) and fewer cases for South African trainees (n = 2, 29%). DISCUSSION: Retention on the African sub-continent of surgeons who trained at UCT was high. SSA doctors can utilize South African post-graduate surgical training programs until their own countries increase their training capacity. The majority of trainees returned to their countries of origin, utilizing their skills in the public and academic sectors, and contributing to the teaching of more trainees. These training partnerships also contribute to knowledge-sharing and facilitate a regional network of African surgeons. Active recruitment of more female trainees is needed to ensure gender equity.

ABSTRACT

By 2030, 70% of cancers will occur in developing countries. Head and neck cancers are primarily a developing world disease. While anatomical location and the extent of cancers are central to defining prognosis and staging, the American Joint Committee on Cancer (AJCC)/International Union Against Cancer (UICC) have incorporated nonanatomic factors that correlate with prognosis into staging (eg, p16 status of oropharyngeal cancers). However, 16 of 17 head and neck surgeons from 13 African countries cannot routinely test for p16 status and hence can no longer apply AJCC/UICC staging to oropharyngeal cancer. While the AJCC/UICC should continue to refine staging that best reflects treatment outcomes and prognosis by incorporating new nonanatomical factors, they should also retain and refine anatomically based staging to serve the needs of clinicians and their patients in resource-constrained settings. Not to do so would diminish their global relevance and in so doing also disadvantage most of the world's cancer patients.

ABSTRACT

The speed and scale of the global COVID-19 pandemic has resulted in unprecedented pressures on health services worldwide, requiring new methods of service delivery during the health crisis. In the setting of severe resource constraint and high risk of infection to patients and clinicians, there is an urgent need to identify consensus statements on head and neck surgical oncology practice. We completed a modified Delphi consensus process of three rounds with 40 international experts in head and neck cancer surgical, radiation, and medical oncology, representing 35 international professional societies and national clinical trial groups. Endorsed by 39 societies and professional bodies, these consensus practice recommendations aim to decrease inconsistency of practice, reduce uncertainty in care, and provide reassurance for clinicians worldwide for head and neck surgical oncology in the context of the COVID-19 pandemic and in the setting of acute severe resource constraint and high risk of infection to patients and staff.
