Prevalence of asthma, aspirin sensitivity and allergy in chronic rhinosinusitis: data from the UK National Chronic Rhinosinusitis Epidemiology Study
2018
Background
Chronic rhinosinusitis (CRS) is a common disorder associated with other respiratory tract diseases such as asthma and inhalant allergy. However, the prevalence of these co-morbidities varies considerably in the existing medical literature and by phenotype of CRS studied. The study objective was to identify the prevalence of asthma, inhalant allergy and aspirin sensitivity in CRS patients referred to secondary care and establish any differences between CRS phenotypes.
Methods
All participants were diagnosed in secondary care according to international guidelines and invited to complete a questionnaire including details of co-morbidities and allergies. Data were analysed for differences between controls and CRS participants and between phenotypes using chi-squared tests.
Results
The final analysis included 1470 study participants: 221 controls, 553 CRS without nasal polyps (CRSsNPs), 651 CRS with nasal polyps (CRSwNPs) and 45 allergic fungal rhinosinusitis (AFRS). The prevalence of asthma was 9.95, 21.16, 46.9 and 73.3% respectively. The prevalence of self-reported confirmed inhalant allergy was 13.1, 20.3, 31.0 and 33.3% respectively; house dust mite allergy was significantly higher in CRSwNPs (16%) compared to CRSsNPs (9%,
p
< 0.001). The prevalence of self- reported aspirin sensitivity was 2.26, 3.25, 9.61 and 40% respectively. The odds ratio for aspirin sensitivity amongst those with AFRS was 28.8 (CIs 9.9, 83.8)
p
< 0.001.
Conclusions
The prevalence of asthma and allergy in CRS varies by phenoytype, with CRSwNPs and AFRS having a stronger association with both. Aspirin sensitivity has a highly significant association with AFRS. All of these comorbidities are significantly more prevalent than in non-CRS controls and strengthen the need for a more individualised approach to the combined airway.

Background
Tinnitus service provision in the United Kingdom has been investigated from the healthcare provider’s perspective demonstrating considerable regional variation particularly regarding availability of psychological treatments. An audiological-based tinnitus service, however, was reportedly available for all tinnitus patients in the UK. The aim of the current study was to define and evaluate nationwide tinnitus healthcare services from the patients’ viewpoint.
Methods
Secondary analyses were performed on data from a 33-item questionnaire provided by the British Tinnitus Association. The questionnaire had been distributed via email and social media.
Results
Responses from 937 participants who had or had previously experienced tinnitus were analysed. All but one person had at some time consulted their GP. About one in five received medication in primary care. The majority were referred to secondary care, generally an ENT surgeon or audiovestibular physician; some were referred directly to audiological services. In secondary care the majority underwent audiometric testing and over half underwent MRI scanning. Drugs were prescribed less frequently in secondary care. About one third of patients were referred onwards from diagnostic services in secondary care to receive therapeutic interventions for tinnitus. Therapy was generally delivered by an audiologist or hearing therapist. Just under two fifths of people discharged from secondary care returned to their GP, with most returning within one year. Over a third of this group were re-referred to secondary care. Few patients saw a psychologist (2.6%) though some psychological treatments were delivered by appropriately trained audiologists. Negative counselling from healthcare professionals in both primary and secondary care settings was reported.
Conclusions
Although the UK has developed a national service for patients with tinnitus many people find it difficult to access, being blocked at the primary care level or after secondary care diagnostic services. Many of those discharged from secondary care return to their GP within a short space of time and are re-referred to secondary care creating an unsatisfactory and expensive revolving-door pattern of healthcare. Despite psychological treatment modalities having the best evidence base for successful tinnitus management, only a minority of tinnitus patients ever get to meet a psychologist.

Trainee-Reported Outcomes of Otology Simulation Training: Examining Effectiveness of the VOXEL-MAN Temporal Bone Simulator as a Training Adjunct in Mastoid Surgery
2025
Mastoid surgery is technically challenging with complex three-dimensional (3D) anatomy. With reduced access to traditional training methods and increasing new technologies available, virtual reality simulation is being evaluated in a regional training program as an adjunct to existing training structures.
Twenty higher surgical trainees were instructed to complete a cortical mastoidectomy and posterior tympanotomy on a VOXEL-MAN simulator (VOXEL-MAN, Hamburg, Germany). A pre- and post-session questionnaire was completed.
The visual analogue score for familiarity with the temporal bone 3D anatomy, cortical mastoidectomy and posterior tympanotomy surgical landmarks increased by 1.8 cm (p<0.0001), 1.4 cm (p<0.0001) and 2.2 cm (p<0.0001), respectively. Thirty percent of trainees felt that they had received adequate otology exposure within the last two years; 20% felt they would acquire enough experience to become a consultant otologist.
The VOXEL-MAN temporal bone simulator is effective in improving perceived anatomical and surgical knowledge and trainee confidence. Incorporating it into training programmes can help trainees compensate for the impact of the pandemic.

Hypertension is a major risk factor for cardiovascular and cerebrovascular disease. Recent studies have identified an association between low vitamin D levels and hypertension. We investigated the association between vitamin D levels and hypertension in the general population. We recruited 400 hypertensive subjects and compared them with 400 age- and sex-matched normotensive subjects. This study was carried out at Yashoda Hospital, Hyderabad, India from January 2015 to December 2017. Both groups underwent risk factor evaluation, estimation of serum 25-hydroxyvitamin D levels, and C-reactive protein (CRP) and liver function tests. Out of the 400 hypertensive subjects, 164 (40.2%) had serum 25-hydroxyvitamin D deficiency, compared with 111 (27.7%) normotensive subjects (p = 0.0001). Deficiency of serum 25-hydroxyvitamin D in hypertensive subjects was significantly associated with CRP positivity, low levels of mean serum calcium, low levels of mean serum phosphorous, high levels of mean alkaline phosphatase (p < 0.0001), and abnormal alanine transaminase (ALT) (p = 0.0015) compared with the same parameters in the normotensive subjects. After adjustment in the multiple logistic regression analysis, serum 25-hydroxyvitamin D deficiency (odds: 1.78; 95% CI: 1.31–2.41), CRP positivity (odds: 1.48; 95% CI: 1.48–2.32) and abnormal ALT (odds: 1.2; 95% CI: 0.98–1.94) were significantly associated with hypertension. Serum 25-hydroxyvitamin D deficiency was significantly associated with hypertension.

Success rates in restoring hearing loss in patients with chronic otitis media: A systematic review
2021
Objective To assess the effectiveness of tympanoplasty in treating chronic otitis media‐related hearing loss, published literature was systematically reviewed to determine the clinical success rate of tympanoplasty at restoring hearing in chronic otitis media patients at a minimum follow‐up period of 12‐months. Data Sources PubMed, Embase and the Cochrane Library. Methods Two independent reviewers performed literature searches. Publications reporting long‐term (≥12‐month) hearing outcomes and complications data on adult and pediatric patients with chronic otitis media were included and assessed for risk of bias and strength of evidence. To assess how tympanoplasty influences long‐term hearing outcomes, data on pure tone audiometry (air‐bone gap) and complications were extracted and synthesized. Results Thirty‐nine studies met the inclusion criteria. Data from 3162 patients indicated that 14.0% of patients encountered postoperative complications. In adult patients, mean weighted air‐bone gap data show closure from 26.5 dB hearing level (HL) (preoperatively) to 16.1 dB HL (postoperatively). In studies that presented combined adult and pediatric data, the mean preoperative air‐bone gap of 26.7 dB HL was closed to 15.4 dB HL. In 1370 patients with synthesizable data, 70.7% of patients had a postoperative air‐bone gap ˂ 20 dB HL at long‐term follow‐up. Finally, subgroup analysis identified that mean improvement in ABG closure for patients with and without cholesteatoma was 10.0 dB HL and 12.4 dB HL, respectively. Conclusion In patients with chronic otitis media, tympanoplasty successfully closed the air‐bone gap to within 20 dB HL in 7/10 cases and had an overall complication rate of 14.0%. Level of Evidence 2a.

Although chronic otitis media is a major cause of conductive and mixed hearing loss, auditory rehabilitation is currently not optimal for this patient group. Planning for hearing rehabilitation must accompany strategies for infection control when surgically managing patients with chronic otitis media. Several barriers prevent adequate hearing restoration in such a heterogeneous patient population. A lack of standardized reporting of surgical interventions, hearing, and quality of life outcomes impedes meta-analyses of existing data and the generation of highquality evidence, including cost-effectiveness data, through prospective studies. This, in turn, prevents the ability of clinicians to stratify patients based on prognostic indicators, which could guide the decision-making pathway. Strategies to improve reporting standards and methods have the potential to classify patients with chronic otitis media preoperatively, which could guide decision-making for hearing restoration with ossiculoplasty versus prosthetic hearing devices. Appropriately selected clinical guidelines would not only foster directed research but could enhance patient-centered and evidence-based decision-making regarding hearing rehabilitation in the surgical planning process.

Introduction
The new Osia® OSI200 implant incorporates a receiver coil and Piezo Power™ Transducer into one monolithic unit. Appropriate planning and surgical approach is needed for suitable positioning of the device.
Method
To optimise the surgical field and provide tension-free wound closure our team have adopted a versatile ‘Sheffield-S’ post-auricular incision which remains hidden within the hairline.
Conclusion
This incision provides adequate exposure for device placement and bone polishing/recessing. The soft tissue approach has resulted in improved operative efficacy particularly in those patients with irregular cortical bone or where pre-existing osseointegrated implants need to be removed or avoided.

Background: Though reports of neurological manifestations of COVID-19 have emerged from various parts of the world, the cohorts reported are from the West and mostly derived from electronic databases. Much remains unknown regarding neuro-COVID in developing countries. India is the second-worst affected country, and this study reports the neurological manifestations of COVID-19 in a comprehensively evaluated cohort. Objective: The aim of this study was to describe the range of neurological manifestations of COVID-19 in India with an emphasis on the risk factors, laboratory and imaging findings and short-term outcome. Methods: Retrospective review of hospital records of all confirmed COVID-19 patients with neurological manifestations, receiving inpatient care in two neurology referral hospitals were done. All demographic, clinical details, investigations, and treatment were analysed. Results: A total of 120 confirmed COVID-19 cases presenting with neurological symptoms were included. The mean age of illness and duration of illness was 48.03 ± 17.3 years and 10.9 ± 17.3 days respectively. New onset of neurological symptoms occurred in 100 cases while 20 patients had worsening of pre-existing neurological illness. Stroke was the commonest neurological disorder (43%), followed by encephalopathy (23%) and Guillain-Barre syndrome (10%). Other unusual neurological manifestations included new-onset headache (7%), seizures including denovo status epilepticus (5%) and meningo-encephalitis (5%). Nearly half of the patients had preceding COVID-19 symptoms. Poor outcome at discharge was seen in 40% and mortality occurred in 15%. Conclusion: Stroke and encephalopathy constitute the most common neurological manifestations. The absence of preceding COVID-19 symptoms in nearly half the cases is striking. Poor outcome was seen in nearly 50% despite early recognition and management.

Case reports of patients with mal-functioning metal-on-metal hip replacement (MoMHR) prostheses suggest an association of elevated circulating metal levels with visual and auditory dysfunction. However, it is unknown if this is a cumulative exposure effect and the impact of prolonged low level exposure, relevant to the majority of patients with a well-functioning prosthesis, has not been studied. Twenty four male patients with a well-functioning MoMHR and an age and time since surgery matched group of 24 male patients with conventional total hip arthroplasty (THA) underwent clinical and electrophysiological assessment of their visual and auditory health at a mean of ten years after surgery. Median circulating cobalt and chromium concentrations were higher in patients after MoMHR versus those with THA (P<0.0001), but were within the Medicines and Healthcare Products Regulatory Agency (UK) investigation threshold. Subjective auditory tests including pure tone audiometric and speech discrimination findings were similar between groups (P>0.05). Objective assessments, including amplitude and signal-to-noise ratio of transient evoked and distortion product oto-acoustic emissions (TEOAE and DPOAE, respectively), were similar for all the frequencies tested (P>0.05). Auditory brainstem responses (ABR) and cortical evoked response audiometry (ACR) were also similar between groups (P>0.05). Ophthalmological evaluations, including self-reported visual function by visual functioning questionnaire, as well as binocular low contrast visual acuity and colour vision were similar between groups (P>0.05). Retinal nerve fibre layer thickness and macular volume measured by optical coherence tomography were also similar between groups (P>0.05). In the presence of moderately elevated metal levels associated with well-functioning implants, MoMHR exposure does not associate with clinically demonstrable visual or auditory dysfunction.

Virtual temporal bone simulators and their use in surgical training: a narrative review
2024
Temporal bone dissection is a difficult skill to acquire, and the challenge has recently been further compounded by a reduction in conventional surgical training opportunities during the coronavirus disease 2019 pandemic. Consequently, there has been renewed interest in ear simulation as an adjunct to surgical training for trainees. We review the state-of-the-art virtual temporal bone simulators for surgical training.
A narrative review of the current literature was performed following a Medline search using a pre-determined search strategy.
Sixty-one studies were included. There are five validated temporal bone simulators: Voxel-Man, CardinalSim, Ohio State University Simulator, Melbourne University's Virtual Reality Surgical Simulation and Visible Ear Simulator. The merits of each have been reviewed, alongside their role in surgical training.
Temporal bone simulators have been demonstrated to be useful adjuncts to conventional surgical training methods and are likely to play an increasing role in the future.
