RESUMEN
BACKGROUND: Patients with severe-to-profound hearing loss may benefit from management with cochlear implants. These patients need a referral to a cochlear implant team for further assessment and possible surgery. The referral pathway may result in varied access to hearing healthcare. This study aimed to explore referral patterns and whether there were any socioeconomic or ethnic associations with the likelihood of referral. The primary outcome was to determine factors influencing referral for implant assessment. The secondary outcome was to identify factors impacting whether healthcare professionals had discussed the option of referral. METHODS AND FINDINGS: A multicentre multidisciplinary observational study was conducted in secondary care Otolaryngology and Audiology units in Great Britain. Adults fulfilling NICE (2019) audiometric criteria for implant assessment were identified over a 6-month period between 1 July and 31 December 2021. Patient- and site-specific characteristics were extracted. Multivariable binary logistic regression was employed to compare a range of factors influencing the likelihood of implant discussion and referral including patient-specific (demographics, past medical history, and degree of hearing loss) and site-specific factors (cochlear implant champion and whether the hospital performed implants). Hospitals across all 4 devolved nations of the UK were invited to participate, with data submitted from 36 urban hospitals across England, Scotland, and Wales. Nine hospitals (25%) conducted cochlear implant assessments. The majority of patients lived in England (n = 5,587, 86.2%); the rest lived in Wales (n = 419, 6.5%) and Scotland (n = 233, 3.6%). The mean patient age was 72 ± 19 years (mean ± standard deviation); 54% were male, and 75·3% of participants were white, 6·3% were Asian, 1·5% were black, 0·05% were mixed, and 4·6% were self-defined as a different ethnicity. Of 6,482 submitted patients meeting pure tone audiometric thresholds for cochlear implantation, 311 already had a cochlear implant. Of the remaining 6,171, 35.7% were informed they were eligible for an implant, but only 9.7% were referred for assessment. When adjusted for site- and patient-specific factors, stand-out findings included that adults were less likely to be referred if they lived in more deprived area decile within Indices of Multiple Deprivation (4th (odds ratio (OR): 2·19; 95% confidence interval (CI): [1·31, 3·66]; p = 0·002), 5th (2·02; [1·21, 3·38]; p = 0·05), 6th (2·32; [1·41, 3·83]; p = 0.05), and 8th (2·07; [1·25, 3·42]; p = 0·004)), lived in London (0·40; [0·29, 0·57]; p < 0·001), were male (females 1·52; [1·27, 1·81]; p < 0·001), or were older (0·97; [0·96, 0·97]; p < 0·001). They were less likely to be informed of their potential eligibility if they lived in more deprived areas (4th (1·99; [1·49, 2·66]; p < 0·001), 5th (1·75; [1·31, 2·33], p < 0·001), 6th (1·85; [1·39, 2·45]; p < 0·001), 7th (1·66; [1·25, 2·21]; p < 0·001), and 8th (1·74; [1·31, 2·31]; p < 0·001) deciles), the North of England or London (North 0·74; [0·62, 0·89]; p = 0·001; London 0·44; [0·35, 0·56]; p < 0·001), were of Asian or black ethnic backgrounds compared to white patients (Asian 0·58; [0·43, 0·79]; p < 0·001; black 0·56; [0·34, 0·92]; p = 0·021), were male (females 1·46; [1·31, 1·62]; p < 0·001), or were older (0·98; [0·98, 0·98]; p < 0·001). The study methodology was limited by its observational nature, reliance on accurate documentation of the referring service, and potential underrepresentation of certain demographic groups. CONCLUSIONS: The majority of adults meeting pure tone audiometric threshold criteria for cochlear implantation are currently not appropriately referred for assessment. There is scope to target underrepresented patient groups to improve referral rates. Future research should engage stakeholders to explore the reasons behind the disparities. Implementing straightforward measures, such as educational initiatives and automated pop-up tools for immediate identification, can help streamline the referral process.

OBJECTIVE: Pure tone audiometry (PTA) is the gold standard for hearing assessment. However, it requires access to specialized equipment. Smartphone audiometry applications (apps) have been developed to perform automated threshold audiometry and could allow patients to perform self-administered screening or monitoring. This study aimed to assess the validity and feasibility of patients using apps to self-assess hearing thresholds at home, with comparison to PTA. METHODS: A multi-center, prospective randomized study was conducted amongst patients undergoing PTA in clinics. Participants were randomly allocated to one of four publicly-available apps designed to measure pure tone thresholds. Participants used an app once in optimal sound-treated conditions and a further three times at home. Ear-specific frequency-specific thresholds and pure tone average were compared using Pearson correlation coefficient. The percentage of app hearing tests with results within ±10 dB of PTA was calculated. Patient acceptability was assessed via an online survey. RESULTS: One hundred thirty-nine participants submitted data. The results of two at-home automated smartphone apps correlated strongly/very strongly with PTA average and their frequency-specific median was within ±10 dB accuracy. Smartphone audiometry performed in sound-treated and home conditions were very strongly correlated. The apps were rated as easy/very easy to use by 90% of participants and 90% would be happy/very happy to use an app to monitor their hearing. CONCLUSION: Judicious use of self-performed smartphone audiometry was both valid and feasible for two of four apps. It could provide frequency-specific threshold estimates at home, potentially allowing assessments of patients remotely or monitoring of fluctuating hearing loss.

HYPOTHESIS: There are clinically relevant differences in scalae anatomy and spiral ganglion neuron (SGN) quantity between incomplete partition type II (IP-II) and normal cochleae. BACKGROUND: IP-II is a commonly implanted cochlear malformation. Detailed knowledge of intracochlear three-dimensional (3D) morphology may assist with cochlear implant (CI) electrode selection/design and enable optimization of audiologic programming based on SGN maps. METHODS: IP-II (n = 11) human temporal bone histological specimens were identified from the National Institute on Deafness and Other Communication Disorders National Temporal Bone Registry and digitized. The cochlear duct, scalae, and surgically relevant anatomy were reconstructed in 3D. A machine learning algorithm was applied to map the location and number of SGNs. RESULTS: 3D scalae morphology of the basal turn was normal. Scala tympani (ST) remained isolated for 540 degrees before fusing with scala vestibuli. Mean ST volume reduced below 1 mm 2 after the first 340 degrees. Scala media was a distinct endolymphatic compartment throughout; mean ± standard deviation cochlear duct length was 28 ± 3 mm. SGNs were reduced compared with age-matched norms (mean, 48%; range, 5-90%). In some cases, SGNs failed to ascend Rosenthal's canal, remaining in an abnormal basalward modiolar location. Two forms of IP-II were seen: type A and type B. A majority (98-100%) of SGNs were located in the basal modiolus in type B IP-II, compared with 76 to 85% in type A. CONCLUSION: Hallmark features of IP-II cochleae include the following: 1) fusion of the ST and scala vestibuli at a mean of 540 degrees, 2) highly variable and overall reduced SGN quantity compared with normative controls, and 3) abnormal SGN distribution with cell bodies failing to ascend Rosenthal's canal.

As the first clinically translated machine-neural interface, cochlear implants (CI) have demonstrated much success in providing hearing to those with severe to profound hearing loss. Despite their clinical effectiveness, key drawbacks such as hearing damage, partly from insertion forces that arise during implantation, and current spread, which limits focussing ability, prevent wider CI eligibility. In this review, we provide an overview of the anatomical and physical properties of the cochlea as a resource to aid the development of accurate models to improve future CI treatments. We highlight the advancements in the development of various physical, animal, tissue engineering, and computational models of the cochlea and the need for such models, challenges in their use, and a perspective on their future directions.

OBJECTIVES: Nurses are increasingly providing routine and emergency ENT care; yet there are often limited training opportunities. The aim of this study was to validate an intensive 1-day ENT emergency simulation course for nurses. METHODS: The course included short lectures, practical skills stations and mannequin simulation scenarios. Sixteen nurse participants were video-recorded managing simulated scenarios before and after the course. Two assessors scored individual participant performance on a 15-point competency grid (maximum score 30), blinded to the timing of the recording. Participants also rated their confidence and skill before and immediately following the course across 11 items using a 5-point Likert score (maximum score 55). RESULTS: Blinded assessor ratings for performance were significantly improved after the course compared to baseline (overall score 12 vs 7, respectively; P = .015). There was strong assessor inter-rater reliability (R = 0.965). Self-rated skills and confidence also increased following the course (46.7 vs 24.4 at baseline; P < .01). CONCLUSION: Simulation-based training is an effective and desirable method of teaching ENT emergency management to nurses, with greatest impact on participant confidence. Future courses need to refine the content and increase the validation sample size using a nurse-specific scoring system.

(1) Background: During a cochlear implant insertion, the mechanical trauma can cause residual hearing loss in up to half of implantations. The forces on the cochlea during the insertion can lead to this mechanical trauma but can be highly variable between subjects which is thought to be due to differing anatomy, namely of the scala tympani. This study presents a systematic investigation of the influence of different geometrical parameters of the scala tympani on the cochlear implant insertion force. The influence of these parameters on the insertion forces were determined by testing the forces within 3D-printed, optically transparent models of the scala tympani with geometric alterations. (2) Methods: Three-dimensional segmentations of the cochlea were characterised using a custom MATLAB script which parametrised the scala tympani model, procedurally altered the key shape parameters (e.g., the volume, vertical trajectory, curvature, and cross-sectional area), and generated 3D printable models that were printed using a digital light processing 3D printer. The printed models were then attached to a custom insertion setup that measured the insertion forces on the cochlear implant and the scala tympani model during a controlled robotic insertion. (3) Results: It was determined that the insertion force is largely unaffected by the overall size, curvature, vertical trajectory, and cross-sectional area once the forces were normalised to an angular insertion depth. A Capstan-based model of the CI insertion forces was developed and matched well to the data acquired. (4) Conclusion: By using accurate 3D-printed models of the scala tympani with geometrical alterations, it was possible to demonstrate the insensitivity of the insertion forces to the size and shape of the scala tympani, after controlling for the angular insertion depth. This supports the Capstan model of the cochlear implant insertion force which predicts an exponential growth of the frictional force with an angular insertion depth. This concludes that the angular insertion depth, rather than the length of the CI inserted, should be the major consideration when evaluating the insertion force and associated mechanical trauma caused by cochlear implant insertion.

OBJECTIVE: To investigate the value of scalp surface potentials to identify and manage partial short circuits to ground in cochlear implant electrodes. DESIGN: A retrospective review of patients with suspected partial short circuits. MAIN OUTCOME MEASURE: Electrical output of individual electrodes was measured using scalp surface potentials for patients reporting a change in hearing function. Electrical output was compared to functional performance and impedance measurements to determine if devices with suspected partial short circuits were experiencing a decrease in performance as a result of reduced electrical output. Electrical output was checked in an artificial cochlea for two implants following explant surgery to confirm scalp surface potential results. RESULTS: All patients with suspected partial short circuits (n = 49) had reduced electrical output, a drop in impedances to approximately ½ of previously stable measurements or to below 2 kΩ, an atypical electrical field measurement (EFI) and a decline in hearing function. Only devices with an atypical EFI showed reduced electrical output. Results of scalp based surface potentials could be replicated in an artificial cochlea following explantation of the device. All explant reports received to date (n = 42) have confirmed partial short circuits, with an additional four devices failing integrity tests. CONCLUSION: Surface potential measurements can detect partial shorts and had 100% correlation with atypical EFI measurements, which are characteristic of a partial short to ground in this device. Surface potentials can help determine the degree to which the electrode array is affected, particularly when behavioural testing is limited or not possible.

RESUMEN
Objectives: The primary aim was to measure the volume of the scala tympani (ST) and the length of the straight portion of the cochlear basal turn from micro-computed tomography (µCT) images. The secondary aim was to estimate the electrode insertion force based on cochlear size and insertion speed. Both of these objectives have a direct clinical relevance in robotic assisted cochlear implant (CI) surgery. Methods: The ST was segmented in thirty µCT datasets to create a three-dimensional (3D) model and calculate the ST volume. The diameter (A-value), the width (B-value), and the straight portion of the cochlear basal turn (S-value) were measured from the oblique coronal plane. Electrode insertion force was measured in ST models of two different sizes, by inserting FLEX24 (24 mm) and FLEX28 (28 mm) electrode arrays at five different speeds (0.1, 0.5, 1, 2, and 4 mm/s). Results: The mean A-, B-, and S-values measured from the 30 µCT datasets were 9.0 ± 0.5, 6.7 ± 0.4, and 6.9 mm ± 0.5, respectively. The mean ST volume was 34.2 µl ± 7 (range 23-50 µl). The ST volume increased linearly with an increase in A- and B-values (Pearson's coefficient r = 0.55 and 0.56, respectively). The A-value exhibited linear positive correlation with the B-value and S-value (Pearson's coefficient r = 0.64 and r = 0.66, respectively). In the smaller of the two ST models, insertion forces were higher across the range of insertion speeds during both array insertions, when compared to the upscaled model. Before the maximum electrode insertion depths, a trend toward lower insertion force for lower insertion speed and vice-versa was observed. Conclusion: It is important to determine pre-operative cochlear size as this seems to have an effect upon electrode insertion forces. Higher insertion forces were seen in a smaller sized ST model across two electrode array lengths, as compared to an upscaled larger model. The ST volume, which cannot be visualized on clinical CT, correlates with clinical cochlear parameters. This enabled the creation of an equation capable of predicting ST volume utilizing A- and B-values, thus enabling pre-operative prediction of ST volume.
RESUMEN
Cochlear implants restore hearing in patients with severe to profound deafness by delivering electrical stimuli inside the cochlea. Understanding stimulus current spread, and how it correlates to patient-dependent factors, is hampered by the poor accessibility of the inner ear and by the lack of clinically-relevant in vitro, in vivo or in silico models. Here, we present 3D printing-neural network co-modelling for interpreting electric field imaging profiles of cochlear implant patients. With tuneable electro-anatomy, the 3D printed cochleae can replicate clinical scenarios of electric field imaging profiles at the off-stimuli positions. The co-modelling framework demonstrated autonomous and robust predictions of patient profiles or cochlear geometry, unfolded the electro-anatomical factors causing current spread, assisted on-demand printing for implant testing, and inferred patients' in vivo cochlear tissue resistivity (estimated mean = 6.6 kΩcm). We anticipate our framework will facilitate physical modelling and digital twin innovations for neuromodulation implants.

BACKGROUND: Endoscopic sinus surgery is performed for medically recalcitrant chronic rhinosinusitis. There is no universally accepted strategy regarding post-operative antibiotics despite the high rates of usage worldwide. The aim of this study was to analyse patient-reported and objective outcomes behind antibiotic use following endoscopic sinus surgery. METHODS: A search of electronic databases was performed. Eligible randomised controlled trials (RCTs) and observational trials were included. The primary outcome was patient reported outcome measures. Secondary outcomes were local infections, endoscopy scores and adverse events. Meta-analysis was performed. RESULTS: Of 1045 publications identified, 7 were included in the qualitative synthesis and 5 RCTs were included in meta-analysis. Antibiotic regimens varied between studies in terms of antibiotic selection, timing commenced and duration of use. Meta-analysis suggested no significant difference between placebo and antibiotics in patient reported outcome measures (standardised mean difference (SMD) -0.215, 95% confidence interval (CI) -0.637 to 0.207) or endoscopic scores (SMD -2.86, 95% CI -0.846 to 0.273). There was no consistent definition in reporting of infection; therefore, this outcome cannot be comprehensively considered. No severe adverse events were attributable to antibiotics. CONCLUSIONS: From the studies analysed, there is no level 1 evidence to suggest that antibiotics improved patient outcomes following sinus surgery. However, there was significant heterogeneity in outcome measures and no clear data exists regarding the effects of antibiotics on postoperative infections. The available evidence at present is not enough to make a recommendation in either direction. Further designed larger RCTs are required to investigate these questions in more detail.

INTRODUCTION: Nasal packing is the mainstay of epistaxis management; however, packs cause patient discomfort and can lead to hospital admission. Absorbable haemostats provide clotting factors or act as a substrate to stimulate clotting and represent a potential treatment alternative. A systematic review was performed to evaluate the efficacy of topical haemostats in the management of epistaxis. METHODS: A systematic literature search of 7 databases was performed. Only eligible randomised controlled trials (RCTs) and observational studies were included. The primary outcome was short-term haemostatic success (<7 days). Secondary outcomes included long-term haemostatic control (no rebleeding 7-30 days), patient discomfort and adverse effects. Meta-analysis was performed where possible. RESULTS: Of 2249 records identified, 12 were included in the qualitative synthesis and 4 RCTs were included in meta-analysis. The following haemostats were reported: gelatin-thrombin matrix (n = 8), aerosolised/gel tranexamic acid (n = 1), cellulose agents (n = 2) and fibrin sealants (n = 1). Studies involving tranexamic acid on removable delivery devices (eg, pledgets) were excluded. There was heterogeneity in outcome measures and inclusion criteria (coagulopathies/anticoagulants were excluded in 3 RCTs and 2 observational studies). The short-term haemostatic success varied between studies (13.9% to 100%). No significant post-procedural complications were reported. The meta-analysis favoured absorbable haemostatic agent versus packing (risk ratio 1.20; 95% confidence interval 1.05 to 1.37; P = .007). The risk of bias across all studies was moderate to high. CONCLUSIONS: The evidence suggests haemostatic agents are effective at managing acute epistaxis when compared with nasal packing. More data are required before recommendations can be made regarding management in patients on anticoagulants.

OBJECTIVES: To report experience with a global multidisciplinary tracheostomy e-learning initiative. METHODS: An international multidisciplinary panel of experts convened to build a virtual learning community for tracheostomy care, comprising a web-based platform, five distance learning (interactive webinar) sessions, and professional discourse over 12 months. Structured pre- and post-webinar surveys were disseminated to global participants including otolaryngologists, intensivists, nurses, allied health professionals, and patients/caregivers. Data were collected on audio-visual fidelity, demographics, and pre- and post-tutorial assessments regarding experience and skill acquisition. Participants reported confidence levels for NICU, pediatric, adult, and family care, as well as technical skills, communication, learning, assessment, and subdomains. RESULTS: Participants from 197 institutions in 22 countries engaged in the virtual education platform, including otolaryngologists, speech pathologists, respiratory therapists, specialist nurses, patients, and caregivers. Significant improvements were reported in communication (P < .0001), clinical assessments (P < .0001), and clinical governance (P < .0001), with positive impact on pediatric decannulation (P = .0008), adult decannulation (P = .04), and quality improvement (P < .0001). Respondents reported enhanced readiness to integrate knowledge into practice. Barriers included time zones, internet bandwidth, and perceived difficulty of direct clinical translation of highly technical skills. Participants rated the implementation highly in terms of length, ability for discussion, satisfaction, applicability to professional practice, and expertise of discussants (median scores: 4, 4, 4, 4 and 5 out of 5). CONCLUSIONS: Virtual learning has dominated the education landscape during COVID-19 pandemic, but few data are available on its effectiveness. This study demonstrated feasibility of virtual learning for disseminating best practices in tracheostomy, engaging a diverse, multidisciplinary audience. Learning of complex technical skills proved a hurdle, however, suggesting need for hands-on experience for technical mastery. While interactive videoconferencing via webinar affords an engaging and scalable strategy for sharing knowledge, further investigation is needed on clinical outcomes to define effective strategies for experiential online learning and virtual in-service simulations.

There is growing recognition of the need for a coordinated, systematic approach to caring for patients with a tracheostomy. Tracheostomy-related adverse events remain a pervasive global problem, accounting for half of all airway-related deaths and hypoxic brain damage in critical care units. The Global Tracheostomy Collaborative (GTC) was formed in 2012 to improve patient safety and quality of care, emphasising knowledge, skills, teamwork, and patient-centred approaches. Inspired by quality improvement leads in Australia, the UK, and the USA, the GTC implements and disseminates best practices across hospitals and healthcare trusts. Its database collects patient-level information on quality, safety, and organisational efficiencies. The GTC provides an organising structure for quality improvement efforts, promoting safety of paediatric and adult patients. Successful implementation requires instituting key drivers for change that include effective training for health professionals; multidisciplinary team collaboration; engagement and involvement of patients, their families, and carers; and data collection that allows tracking of outcomes. We report the history of the collaborative, its database infrastructure and analytics, and patient outcomes from more than 6500 patients globally. We characterise this patient population for the first time at such scale, reporting predictors of adverse events, mortality, and length of stay indexed to patient characteristics, co-morbidities, risk factors, and context. In one example, the database allowed identification of a previously unrecognised association between bleeding and mortality, reflecting ability to uncover latent risks and promote safety. The GTC provides the foundation for future risk-adjusted benchmarking and a learning community that drives ongoing quality improvement efforts worldwide.

OBJECTIVES: Observational studies often represent the best available evidence for surgical practice. Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) recommendations were generated in 2007 with the aim of improving the quality of reporting. This study was designed to assess whether publication of STROBE guidelines has improved the quality of reporting in observational otology and audiology studies. DATA SOURCES: EMBASE and MEDLINE were searched using a comprehensive keyword search developed in conjunction with a scientific librarian. STUDY SELECTION: English language papers from six Otorhinolaryngology journals during two 6-month periods (2005 and 2016) were evaluated. DATA EXTRACTION: Two reviewers independently analyzed papers according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SYNTHESIS: Percentage scores for the two periods were compared using Mann-Whitney U test. CONCLUSIONS: Forty and 42 studies were returned for the 2005 and 2016 periods, respectively. The mean percentage of STROBE items that were met improved between 2005 and 2016 (58, 76%, respectively; pâ<â0.0001). Analysis indicated that improvements were greater in journals that endorsed STROBE guidelines (pâ=â0.02). This data suggests that STROBE has increased the reporting quality of observational studies; however, there are still significant further improvements to be met.

Three patients presented within a 6-month period with pneumomediastinum. The underlying cause in each was distinct. One case occurred due to blunt laryngeal trauma and required urgent surgical intervention due to a decompensating airway. The second case was related to tracheal perforation secondary to a myofibroblastic tracheal tumour and the final case was related to adenovirus upper respiratory tract infection. Pneumomediastinum may be spontaneous or secondary to an underlying cause. Children should be managed using a multidisciplinary approach. Investigation and management should be influenced by clinical stability and invasive procedures should only be considered in patients who exhibit respiratory distress.

It is imperative that primary care referrals are directed to the appropriate secondary care service. Patients presenting to a primary care physician with ENT conditions may require review in an Emergency Clinic. The latter clinics provide patients with rapid access to secondary care, for urgent, yet non-life-threatening conditions. In our department, we noticed that patients with conditions inappropriate to the capabilities of the Clinic were being booked in or reviewed too late; thus causing wasted journeys for the patient. We conducted a Quality Improvement Project to improve the efficiency of the referral process. A prospective evaluation of referrals was collected continuously over a two-month period. Overall, 5 domains were deemed crucial to enable timely and accurate booking of patients to clinic: booking date, urgency, legibility, patient identification and appropriateness. Our proposed standard set for this project was 100% compliance over the 5 domains. Three separate interventions were instigated following the first cycle. The main components of the intervention were the phased development of an electronic referral system and an educational initiative for junior doctors. 20 referral forms were analysed during the initial 3-week period. No referrals met the recommended overall compliance standard of 100% (mean number of domains achieved: 3.38; standard deviation (SD): 0.637). Legibility and patient information were included in 21% and 30% of referrals, respectively. There was a trend of improvement following initiation of interventions. The mean number of domains achieved was 4.27 (SD 0.647; n=13) in the second data collection period, 4.53 (SD 0.514; n=16) in the third, and 4.75 (SD 0.452; n=24) in the fourth. Using linear regression, this change demonstrates a statistically significant improvement (p<0.001). An e-Proforma referral system represents a safe and efficient communication technology. When implementing policy change, it is crucial to acquire managerial and consultant support.
