HPV overtakes smoking as the leading cause of oropharyngeal cancer in Ireland: experience of a head and neck surgery tertiary referral centre.

BACKGROUND: Worldwide, the incidence of oropharyngeal squamous cell carcinoma (OPSCC) caused by human papillomavirus (HPV), a sexually transmitted virus, is increasing. This increase has yet to be demonstrated in an Irish cohort. AIMS: To evaluate the number of OPSCC presentations locally, to stratify cases by HPV status and to estimate if any changes in the patient population had occurred over a 10-year period. METHODS: A STROBE-compliant, retrospective evaluation of patients with OPSCC at St James's Hospital between 2012 and 2022 was performed. Patients with non-SCC histology, undocumented HPV status and residual or recurrent tumours were excluded. RESULTS: We included 294 patients with a mean age of 60.4 years (95% CI 59.2-61.5 years) and 175 (59.5%) patients had HPV+ OPSCC. The number of new OPSCC diagnoses increased from 115 patients (39.1%) between 2012 and 2016 to 179 patients (60.9%) between 2017 and 2021. This was associated with an increased proportion of HPV-linked OPSCC (50.4% 2012-2016 vs. 65.4% 2017-2021, p = 0.011). Over time, more patients had a functionally limiting comorbidity (p = 0.011). The mean age of HPV+ OPSCC cases increased by 3.6 years (p = 0.019). Patients with HPV+ OPSCC had greater 2-year OS (83.9% vs. 54.9%; p < 0.001) and 2-year DFS (73.5% vs. 45.6%; p < 0.001). The 2-year OS and DFS did not change over time for HPV+ or HPV- patients. CONCLUSIONS: In our institution, the number of patients with OPSCC is increasing due to an escalation in cases associated with HPV. Population-level interventions such as vaccination programs may alter the current increase in the incidence of these tumours.

Fatal cerebritis and ventriculitis secondary to tracheoesophageal prosthesis.

Tracheoesophageal puncture and voice prosthesis placement is the preferred method of voice restoration following total laryngectomy. Although this is a safe and effective means of optimizing voice, severe complications can occur. We present the case of a patient who developed cerebritis and ventriculitis secondary to a tracheoesophageal prosthesis eroding his cervical vertebrae 20 years following pharyngo-laryngo-esophagectomy. Despite optimal antimicrobial therapy, he deteriorated and succumbed to his disease. Although tracheoesophageal prostheses are a safe and effective means of voice restoration, life-threatening complications can occur. This case report highlights a rare but severe case of cervical osteomyelitis, epidural abscess, and cerebritis and ventriculitis secondary to tracheoesophageal prosthesis. Clinicians must be aware of this severe complication in postlaryngectomy patients with tracheoesophageal prostheses.

The role of surgery for anaplastic thyroid carcinoma in the era of targeted therapeutics: A scoping review.

Background: Questions exist regarding patient selection for surgery in anaplastic thyroid carcinoma (ATC), particularly with the advent of neoadjuvant-targeted therapeutics. The present scoping review sought to evaluate what extent of surgical resection should be performed in ATC. Methods: A scoping review was carried out in accordance with Joanna Briggs Institute and the preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews (PRISMA-ScR) protocols. Included studies were required to provide clear description of the surgery performed for ATC. Results: The final search identified 6901 articles. Ultimately only 15 articles including 1484 patients met inclusion criteria. A total of 765 patients (51.5%) underwent attempted curative intent surgery. The approach to resection of adjacent tissues varied between studies. Eight studies considered laryngeal ± pharyngeal resection (8/15, 53.3%), eight studies (53.3%) considered tracheal resection and again eight studies (53.3%) considered esophageal resection. More extensive resections increased morbidity without improving overall survival (OS) (<9 months in the 12 studies using a combination of surgery and chemoradiotherapy). In the three studies utilizing targeted therapy in addition to surgery, OS was notably improved while surgical resection following neoadjuvant therapy was less extensive. Conclusions: There is no clear agreement in the literature regarding the limits of surgical resection in locoregionally advanced ATC. A definition of surgically resectable disease will be required to guide surgical decision making in ATC, particularly with the potential to reduce tumor burden using neoadjuvant targeted treatment in suitable patients. Level of evidence: III.

Training in Endoscopic Ear Surgery: A Scoping Review.

OBJECTIVE: Despite the increasing popularity of Endoscopic Ear Surgery (EES), there is a lack of evidence to guide trainees as they introduce EES into practice. This review aims to evaluate training in EES including the optimal introductory procedures, methods of training, the learning curve, and the determination of competency in EES. In addition, this review seeks to identify any areas falling within these themes requiring further clarification. DATA SOURCES: A database search of Pubmed, Embase and the Cochrane Library was conducted in June 2022. Original articles, systematic reviews, and meta-analyses reporting on training in EES, introduction into practice, learning curves, and competency assessment were included. REVIEW METHODS: A scoping review was carried out in accordance with the Joanna Briggs Institute guidelines and reported according to PRISMA guidelines for scoping reviews. A qualitative assessment of results grouped thematically was performed. RESULTS: Twenty-eight studies met the inclusion criteria, with 24 rating as "fair" or "good" on quality assessment. Surgical simulation was the most frequently described method of training as utilized in 11 studies. The most suggested introductory procedure was tympanoplasty which was advocated for in five studies. Heterogeneity existed in the outcomes and methodologies used to measure EES learning curves, with an overreliance on surgical times. No robust definition of competency in EES procedures exists at present. CONCLUSIONS: Surgical simulation appears to be a beneficial training methodology for EES. However, there is a marked lack of objective data to describe the optimal introductory procedures or assessment of competency in EES. Laryngoscope, 133:3269-3278, 2023.

Trans-canal tragal cartilage myringoplasty; a comparative analysis of endoscopic and microscopic approaches.

BACKGROUND: The advent of Endoscopic Ear Surgery (EES) has allowed otologists an improved view of the surgical field compared with conventional Microscopic Ear Surgery (MES). EES presents different challenges for surgeons and a learning curve is necessary. AIMS: The purpose of this study was to compare the efficacy of EES and MES for trans-canal tragal cartilage myringoplasty, an entry level EES. METHODS: We retrospectively analysed patients who underwent push through trans-canal tragal cartilage myringoplasty in our institution over 5 years (2016-2020). Exclusion criteria were: patients with prior ear surgery, non-tragal cartilage tympanic membrane graft, additional procedure at time of surgery and patients with insufficient follow up. EES and MES groups were compared using outcomes such as graft success rate, changes in pure tone audiometry (PTA), operative time and complications. RESULTS: Seventy-four patients met inclusion criteria (MES = 38, EES = 36). Mean age of included patients was 29.3 years with no significant demographic differences between groups. Graft success rate at 12 months was higher among the EES group versus MES (94.4% v 86.8%, p = 0.43). Mean operative time was reduced in the EES group (47.3 min v 53.8 min, p = 0.04). Hearing outcomes did not differ significantly between groups. No major operative complications occurred in either group. CONCLUSIONS: Outcomes were marginally better in the cohort who underwent EES. This supports that EES offers an otologic choice to complement established practice for trans-canal myringoplasty and may be used to facilitate introduction to EES for trainees and otologists wishing to learn this technique.

Endoscopic Versus Microscopic Type-1 Tympanoplasty: A Meta-Analysis of Randomized Trials.

OBJECTIVES: Totally endoscopic ear surgery is becoming increasingly utilized in otologic practice. Although the well-established microscope-assisted tympanoplasty remains the most common technique to repair a tympanic membrane defect, the merits of endoscopic approaches have been well-documented. This systematic review and meta-analysis compares the outcomes of endoscopic to microscopic tympanoplasty incorporating only randomized trials. STUDY DESIGN: Systematic review and meta-analysis. METHODS: A comprehensive search of PubMed/MEDLINE, Scopus, Cochrane Library, and EMBASE was conducted. All randomized studies comparing endoscopic to microscopic tympanoplasty were collected according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Quality assessment was carried out utilizing the Risk of Bias 2. RESULTS: The initial search identified 1711 studies, of which 9 met the inclusion criteria comprising of 540 patients (microscopic tympanoplasty 51.5%; endoscopic tympanoplasty 49.5%). The mean age was 32.5 years with a similar number of males (50.1%) and females (49.9%). Both endoscopic and microscopic groups had comparable outcomes with regards to graft success rate (RD 0.00; 95% confidence interval [CI], -0.04 to. 0.05; p = 0.87) and hearing improvement (MD 0.57 dB; 95% CI, -1.23 to 2.36; p = 0.54). A significantly shorter operative time was noted in the endoscopic group (MD, -24.73 min; 95% CI, -38.56 to -10.89; p = 0.0005). CONCLUSION: Our results, assimilating level 1 evidence, demonstrates that endoscopic and microscopic-assisted type-1 tympanoplasty have similar outcomes in both graft success and hearing improvement, with endoscopic approaches yielding a shorter operative time. LEVEL OF EVIDENCE: 1 Laryngoscope, 133:1550-1557, 2023.

Clinical decision making in paediatric otitis media: A pilot quality improvement study.

OBJECTIVES: This study aimed to improve local management of paediatric otitis media using the 2022 American-Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) Clinical Practice Guideline for Tympanostomy Tubes in Children. METHODS: A SQUIRE 2.0 compliant quality improvement study was carried out within the outpatient department of our otolaryngology tertiary referral centre. Local outpatient management of paediatric otitis media was compared to the AAO-HNS guidelines, specifically focussing on the decision to offer tympanostomy tubes. Following initial audit of practice, an educational session was performed within the otolaryngology department and local practice was subsequently re-evaluated. RESULTS: Overall, 88 children were included (46 pre-intervention and 42 post-intervention) with a mean age of 7.6 years (range 1-12 years). Sixty-four (72.7%) children presented with suspected otitis media with effusion. The remainder presented with recurrent or persistent acute otitis media (24/88, 27.3%). Twenty-six children were offered tympanostomy tubes (29.5%). Initial evaluation of practice identified that the decision to offer tympanostomy tubes was guideline appropriate in 76.1% of children (35/46). This significantly improved following an educational session (40/42, 95.2%, p = 0.02). The reasons for non-guideline compliance included: otitis media with effusion <3 months, no evidence of middle ear fluid and patients meeting criteria for tympanostomy tube insertion not being offered. CONCLUSIONS: A focussed educational intervention may improve local adherence to guidelines in the management of paediatric otitis media. Continued re-evaluation of local practice is essential in order to ensure children are managed in accordance with the guidelines.

Hypocalcaemia following thyroidectomy among patients who have previously undergone bariatric surgery: systematic review and meta-analysis.

BACKGROUND: Hypocalcaemia is a common complication after thyroidectomy. Bariatric surgery is associated with significant changes in calcium metabolism. Some studies have identified bariatric surgery as a risk factor for hypocalcaemia after thyroidectomy. This systematic review and meta-analysis assessed whether a history of bariatric surgery was associated with an increased risk of hypocalcaemia after thyroidectomy. METHODS: This prospectively registered systematic review (PROSPERO; CRD42021295423) was performed in accordance with PRISMA guidelines. Meta-analysis was undertaken using the Mantel-Haenszel method, with outcomes reported as ORs with 95 per cent confidence intervals. RESULTS: Twenty studies were included in the qualitative synthesis. Five studies incorporating 19 547 patients met the inclusion criteria for meta-analysis, of whom 196 (1.0 per cent) had a history of bariatric surgery. Patients with a history of bariatric surgery were more likely to develop hypocalcaemia after thyroidectomy (30.6 versus 13.0 per cent; OR 3.90, 95 per cent c.i. 1.50 to 10.12; P = 0.005). Among those with a history of bariatric surgery, patients who underwent a bypass procedure were more likely to develop hypocalcaemia after thyroidectomy than those who had a restrictive procedure (38 versus 23 per cent; OR 2.12, 1.14 to 3.97; P = 0.020). CONCLUSION: Patients with a history of bariatric surgery have a significantly greater risk of hypocalcaemia after thyroidectomy, with a heightened risk among those who have had a bypass procedure. Surgeons performing thyroid surgery should be aware of the increased risk of hypocalcaemia after thyroidectomy among these patients.

Low calcium levels are a common complication after surgical removal of the thyroid gland. Patients who have had weight loss surgery (bariatric surgery) have altered calcium metabolism and are prone to low calcium levels. This study assessed whether previous weight loss surgery increased the risk of low calcium levels after thyroid surgery. A search was made of previously published studies assessing the relationship between previous weight loss surgery and low calcium levels after thyroid surgery. Studies have shown that previous weight loss surgery makes patients more than three times more likely to have low calcium levels after thyroid surgery. Management of low calcium in these patients is more challenging than in patients who have not had weight loss surgery. Surgeons performing thyroid surgery need to be aware of whether a patient has previously had weight loss surgery as they have an increased risk of low calcium after thyroid surgery.

The academic impact of 20 years of Irish otolaryngology society conferences.

BACKGROUND: & Purpose: The Irish Otolaryngology Society (IOS) conference takes place annually. This conference allows surgeons and surgical trainees from Ireland and abroad an opportunity to showcase research ideas from their respective centres. This allows them to disseminate results, accept critique, and obtain different perspectives. We sought to examine research presented at the IOS meetings over 20 years. We aimed to analyse the publication rates, impact factor of journals, and citation rates of presented abstracts. METHODS: All oral presentations from IOS conferences were analysed between 2000 and 2019. Presentation titles and authors were searched using Pubmed, Google Scholar and Research Gate. We identified scientific publications which resulted from the research presented and the characteristics of each publication. RESULTS: Of 703 presentations made at the conferences spanning 20 years, 30.15% (n = 212) went on to publish their research averaging 19 citations per publication. Median time to publication was 2 years (-1-11). Each year there have been an increasing number of oral presentations with a declining publication rate. CONCLUSION: The Irish otolaryngology society meeting is a high-quality meeting with comparable publication rates to similar international conferences. Despite this, many presentations do not have any lasting impact as they are not published. The increasing pressure for trainees to rapidly present research projects without emphasis on completion of projects may explain the declining publication rate. Our study highlights the importance of completing high-quality research projects through publication. Meaningful conclusions from these projects can add to the body of knowledge and contribute to evidence-based practice.

The psychological impact of COVID-19 on ear, nose and throat (ENT) specialists.

INTRODUCTION: Ear, nose and throat (ENT) specialists are a high-risk group for COVID-19. Although the implications of SARS-CoV-2 infection on physical health are well-documented, the psychological impact is frequently overlooked. AIMS: The aim of this study was to gauge the psychological impact of COVID-19 on ENT specialists in Ireland. METHODS: A national, cross-sectional, web-based survey was distributed to ENT specialists during the peak of the COVID-19 pandemic (21st May 2020-21st June 2020). The questionnaire collected sociodemographic and COVID-19 related data. The GAD-7 was utilized to measure symptoms of clinically significant anxiety disorder. RESULTS: Thirty-eight ENT specialists (M/F:24/12, median age, 38.7 years (23-60 years)) completed the survey. About 34% (n = 13) of participants screened positive for an anxiety disorder, of which 2 (5%) had moderate symptoms. The majority of participants (n = 32, 84%) felt ENT specialists had increased exposure to SARS-CoV-2 compared with other medical specialties. Additionally, 32% (n = 12) felt incapable of protecting themselves from infection. An encouraging proportion of ENT specialists (n = 22, 58%) were aware of psychological support available from national and institutional organizations. CONCLUSIONS: The long-term psychological sequelae of COVID-19 will be felt as the physical burden eases. As we adjust to new normalities, ENT surgeons must be conscientious of the mental health issues that arise from the working environment. Sources of anxiety emanated from a lack of control over infection risk, increased vulnerability to COVID-19 relative to other specialties and the implications this has for ENT specialists and their families. Future interventions must focus on increasing awareness of the available psychological support services for our healthcare workers.

Sexual Behaviour and Human Papillomavirus-Positive Oral Cavity and Oropharyngeal Cancer: An Irish Perspective.

Background Characterization of the sexual behaviours and lifestyle factors associated with human papillomavirus (HPV)-positive oral cavity and oropharyngeal squamous cell carcinoma (OPSCC) is crucial to optimal counselling. Our study aims to investigate the relationship between sexual behaviours, lifestyle factors and HPV-positive OPSCC in an Irish population. Methods We performed a case-control study of 60 patients with newly diagnosed HPV-positive and HPV-negative oral cavity and OPSCC. Results Oral sexual activity was more common in the HPV-positive tumour subgroup; however, this association was insignificant on multivariate analysis. No association between age of onset of sexual activity, number of sexual partners or practicing anal sex and HPV-positivity was found. The HPV-positive tumour subgroup had significantly less tobacco use than their HPV-negative counterparts (OR 0.93, 95% CI 0.90-0.97). Conclusion The emergence of HPV-positive OPSCC means head and neck surgeons must adopt new roles as counsellors of sexually transmitted disease, in addition to their previous role of delivering a cancer diagnosis.
