This study was a systematic review to investigate the progression of untreated obstructive sleep apnoea in order to evaluate whether mild obstructive sleep apnoea should be treated from the standpoint of disease progression.

The database search study outcomes that were collected included Apnea Hypopnea Index and Respiratory Disturbance Index. A meta-analysis of obstructive sleep apnoea severity over time intervals was performed.

A total of 17 longitudinal studies and 1 randomised, controlled trial were included for review. For patients with mild obstructive sleep apnoea, mean pre-study and post-study Apnea Hypopnea Index was 5.21 and 8.03, respectively, over a median interval of 53.1 months. In patients with moderate to severe obstructive sleep apnoea, mean pre-study and post-study Apnea Hypopnea Index was 28.9 and 30.3, respectively, over a median interval of 57.8 months. Predictors for disease progression in mild obstructive sleep apnoea are patients aged less than 60 years and those with a baseline body mass index less than 25.

Mild obstructive sleep apnoea progression is observed, but it does not appear to reach any clinically significant progression to moderate or severe obstructive sleep apnoea.

This study aimed to identify associative factors for tracheostomy in patients presenting with airway obstruction.

Data from a tertiary hospital were reviewed to identify patients who presented with airway obstruction between 2009 and 2020. Patient demographics, causative pathology and treatments were analysed.

The study identified 297 admitted patients. Of these, 66 underwent a tracheostomy and formed the ‘tracheostomy’ group and 231 formed the ‘other intervention’ group. The tracheostomy group had a higher mean age (p = 0.003), and higher percentages of males (p = 0.031) and smokers or ex-smokers (p = 0.020), compared to the other intervention group. The tracheostomy group also had a higher number of patients with a malignancy (p < 0.001) compared to the other intervention group.

Being older, male, a previous or current smoker, or developing airway obstruction due to a malignancy were found to be the main associative factors for requiring a tracheostomy.

Hearing impairment in older adults may affect cognitive function and increase the risk of dementia. Most cognitive tests are delivered auditorily, and individuals with hearing loss may fail to hear verbal instructions. Greater listening difficulty and fatigue in acoustic conditions may impact test performance. This study aimed to examine the effect of decreased audibility on cognitive screening test performance in older adults.

Older adults (n = 63) with different levels of hearing loss completed a standard auditory Mini-Mental State Examination test and a written version of the test.

Individuals with moderate to moderately severe hearing loss (41–70 dB) performed significantly better on the written (24.34 ± 4.90) than on the standard test (22.55 ± 6.25), whereas scores were not impacted for mild hearing loss (less than 40 dB).

Hearing evaluations should be included in cognitive assessment, and test performance should be carefully interpreted in individuals with hearing loss to avoid overestimating cognitive decline.

To assess hearing rehabilitation in patients with congenital aural atresia using an active middle-ear implant (Vibrant Soundbridge).

Of a cohort of 70 microtia and atresia patients, 10 underwent Vibrant Soundbridge implantation between 2008 and 2021. Two of the 10 patients had binaural implantation, resulting in 12 ears for analysis. Pre- and post-operative audiometry data were analysed, and patient satisfaction was evaluated. Surgical issues regarding coupling sites and outcomes were analysed.

Pure tone average (0.5, 1, 2 and 4 kHz) improved from a pre-operative mean (standard deviation) of 65.3 (8.7) dB HL to a post-operative mean of 26.8 (4.9) dB HL. This resulted in a mean pure tone average gain of 38.5 dB HL. The results indicate no obvious difference between stapes (n = 8) and incus (n = 4) coupling. The mean effective gain for 0.5, 1, 2 and 4 kHz was −17.8 dB HL (standard deviation = 4.3). Concerning effective gain, Vibrant Soundbridge performed best at 2 kHz. Patients reported high overall satisfaction, good sound quality and strongly improved directional hearing.

An active middle-ear implant (Vibrant Soundbridge) allows hearing rehabilitation in selected atretic ears, and provides long-term hearing stability in children and adults.

This study primarily assessed ENT surgical trainees’ preferences for the qualities of disposable and reusable fibre-optic nasendoscopes. Secondary aims included eliciting trainees’ views on ENT surgery and climate change, and creating a single-centre per-use cost analysis for disposable and reusable fibre-optic nasendoscopes.

A cross-sectional study was formulated. An online survey consisting of multiple-choice and Likert-scale questions was distributed nationally. Cost analysis was performed using 2021–2022 data from the host institution.

Twenty-four trainees responded. Data on disposable fibre-optic nasendoscopes showed no difference in overall satisfaction (p = 0.244). Reusable fibre-optic nasendoscopes had a lower cost per use compared with disposable nasendoscopes at 5 years (4.7 per cent reduction) and 10 years (7.1 per cent reduction). Of the trainees, 79.2 per cent were supportive of climate-friendly initiatives within ENT surgery, and 25 per cent felt supported by their departments.

Trainees’ satisfaction with disposable and reusable fibre-optic nasendoscopes is similar. Cost analysis favours reusable fibre-optic nasendoscopes in the long term at the host institution. Empowering departments and trainees to pursue climate-friendly initiatives should be encouraged.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) may be among the viral agents that affect the audio-vestibular system. This study aimed to investigate vestibular symptoms and videonystagmographic examinations in recovered coronavirus disease 2019 (Covid-19) patients compared with the control group.

The patients were evaluated with Vertigo Symptom Scale questionnaire and audiometric, tympanometric, stapedial reflex and videonystagmographic examinations.

A total of 92 of the patients in the coronavirus disease 2019 patients group and 25 of the volunteers in the control group were included in the study. The mean Vertigo Symptom Scale score was found to be significantly higher (p < 0.001) in the coronavirus disease 2019 group. Furthermore, one of the hospitalised patients was diagnosed with vestibular neuritis.

The vestibular system may also be affected in some coronavirus disease 2019 patients. Although this may be seen as dizziness in some patients, in rare cases it can cause severe issues, such as vestibular neuritis.

This study aimed to discuss the role of large cavity functional endoscopic sinus surgery in the management of chronic rhinosinusitis with nasal polyps in patients with non-steroidal anti-inflammatory drug exacerbated respiratory disease.

This was a retrospective review of patients undergoing large cavity functional endoscopic sinus surgery for non-steroidal anti-inflammatory drug exacerbated respiratory disease from January 2016 to March 2022. Population characteristics, pre- and post-operative number of functional endoscopic sinus surgical procedures, endoscopic polyp grade, Lund–Mackay score and nasal symptoms were recorded.

Thirteen consecutive patients with a median age of 47 years were included. They all failed maximal medical treatment and/or conservative functional endoscopic sinus surgery and underwent large cavity sinus surgery followed by post-operative maximal medical therapy. All patients showed an improvement in nasal symptoms with improved Lund–Mackay scores post-operatively. The median length of follow up was 1.5 years.

Large cavity functional endoscopic sinus surgery seems to halt the progression of chronic rhinosinusitis with nasal polyps in non-steroidal anti-inflammatory drug exacerbated respiratory disease. In this case series, large cavity functional endoscopic sinus surgery combined with optimal post-operative medical treatment appeared to switch off chronic rhinosinusitis with nasal polyps in patients with non-steroidal anti-inflammatory drug exacerbated respiratory disease.

This study aimed to explore the utility of the eosinophil percentage in peripheral blood for guiding post-operative glucocorticoid therapy in patients with chronic rhinosinusitis with nasal polyps.

Forty-four patients with chronic rhinosinusitis with nasal polyps underwent functional endoscopic sinus surgery and were randomly divided into two groups. Patients in the standard treatment group used oral and nasal spray glucocorticoids. In the biomarker treatment group, patients with peripheral blood eosinophil percentage values less than 3.05 per cent did not receive glucocorticoid treatment, whereas patients with values 3.05 per cent or above were part of the standard treatment group. Visual Analogue Scale, Sino-Nasal Outcome Test-22 scores, endoscopic Lund–Kennedy scores, eosinophils, interleukin-5 and eosinophil cationic protein in peripheral blood, and nasal secretions were measured.

After functional endoscopic sinus surgery, the Visual Analogue Scale, Sino-Nasal Outcome Test-22 and Lund–Kennedy scores were significantly reduced in both groups; there were no significant differences in those indicators between the groups during the three follow-up visits.

Peripheral blood eosinophil percentage offers a potential biomarker to guide post-operative glucocorticoid therapy in patients with chronic rhinosinusitis with nasal polyps.

Given the uncertainty regarding the predictive value of unilateral tonsillar enlargement and/or lesion in malignancies, this study aimed to evaluate the efficacy of unilateral tonsillar enlargement and/or lesion referral criterion in the adult suspected head and neck cancer pathway.

All two-week wait referrals received in 2018–2019 were reviewed. All patients referred with unilateral tonsillar enlargement and/or lesion were included and analysed for patient demographic data, presenting symptoms, initial clinic outcomes and final diagnoses.

A total of 4934 urgent head and neck cancer referrals were analysed, and 1.9 per cent of these had unilateral tonsillar enlargement and/or lesion. Only 10 patients were diagnosed with tonsil cancer. All the positive tonsil cancer cases had at least one additional head and neck red flag symptom.

The referral criterion for unilateral tonsillar enlargement and/or lesion may be of limited benefit in an already economically challenged National Health Service. Further multicentre studies should be undertaken to refine conclusions on the value of unilateral tonsillar enlargement and/or lesion alone as a criterion for the head and neck cancer two-week wait pathway.

This study aimed to investigate predictive factors for revision surgery in otosclerosis.

This was a retrospective, multicentre study in four tertiary centres. The primary objective was to investigate factors that were predictive of the need for revision stapes surgery.

The ‘revision’ group included 145 patients, and the ‘control’ group included 143 patients. This study identified statistically significant predictive factors for the need for revision surgery: younger age, active smoking status, dyslipidaemia and high blood pressure. There was no statistically significant difference between the two groups in terms of surgical technique or stapedotomy technique.

This study showed that patients who are candidates for primary stapes surgery with younger age, active smoking status, dyslipidaemia and high blood pressure are at higher risk of needing revision surgery. A holistic approach prior to stapes surgery with multidisciplinary assessment is recommended. These results are important for better patient counselling on expected outcomes and risks.

In the UK, guidance recommends ultrasound scanning alone or in combination with sestamibi scintigraphy to guide surgery in patients with primary hyperparathyroidism. If an adenoma is localised on imaging, this can facilitate targeted or minimally invasive surgery. Surgeon-performed ultrasound scan on the operating table benefits from being performed on an anaesthetised patient with optimal positioning. The aim of this study was to investigate the efficacy of intra-operative, blinded, surgeon-performed ultrasound scan in localisation of parathyroid adenomas.

Prospective data were collected on consecutive patients undergoing surgery for primary hyperparathyroidism at a single tertiary centre from November 2019 to June 2021. Patients underwent blinded, surgeon-performed ultrasound scan under general anaesthesia immediately prior to surgery. Localisation results from pre-operative imaging and surgeon-performed ultrasound scan were then compared with the intra-operative findings.

Forty-nine patients underwent surgery and were found to have single-gland disease. Sestamibi scintigraphy, radiologist-performed ultrasound scan and surgeon-performed ultrasound scan had sensitivities of 59.4, 43.75 and 73.8 per cent, respectively. Surgeon-performed ultrasound scan had a statistically significantly increased sensitivity compared with radiologist-performed ultrasound (p < 0.05).

Intra-operative, surgeon-performed ultrasound scan is effective in localising parathyroid adenomas and may be a useful adjunct to facilitate minimally invasive parathyroid surgery.

This quality improvement project assessed the outcomes of telephone consultations for ENT patients in order to identify areas where telephone consultations may be useful in the long term.

New ENT patient appointments in May 2019 and May 2020 were reviewed. Total outcomes as well as subspecialty-specific and presentation-specific outcomes were compared for telephone versus face-to-face consultations.

There were 638 consultations in total (465 in 2019 and 173 in 2020). Following telephone consultations, more patients were followed up and fewer patients were listed for surgery or discharged. Overall outcomes for subspecialties followed the general trend, albeit with a few variations.

Lack of clinical examination in telephone consultations likely affects confidence in making a diagnosis and therefore discharging or listing patients for surgery. Nevertheless, looking at specialty-specific and presentation-specific data, there may be a role for telephone consultations in selected patients.

This study aimed to examine the association between nasal septal deviation and antrochoanal polyp.

This was a retrospective review of medical records and imaging of patients who underwent endoscopic sino-nasal surgery for antrochoanal polyp.

Forty-eight patients operated on for antrochoanal polyp between 2009 and 2019 were eligible for the study. The median age was 32 years, and 52.1 per cent were male. Antrochoanal polyp was diagnosed equally in the right and left nasal cavities. Septal deviation was present in 77 per cent of such cases. In 44 per cent of septal deviation cases, the antrochoanal polyp was ipsilateral to the deviation, which was not statistically significant. The type of deviation according to the Mladina classification was not correlated with the laterality of septal deviation and antrochoanal polyp.

The laterality of the septal deviation was not found to be correlated with that of the antrochoanal polyp. Therefore, performing routine septoplasty during antrochoanal polyp surgery is unnecessary unless the deviation interferes with the complete extraction of the polyp.

A standard lateral neck dissection should yield at least 18 lymph nodes. The goal of the present study was to examine what factors might influence the number of lymph nodes retrieved during a neck dissection.

This was a retrospective cohort study in a tertiary academic referral centre for head and neck oncology. Two hundred and nineteen consecutive neck dissections were examined. Age of the patient and primary site were recorded, along with tumour histology, previous radiotherapy and final nodal count.

The mean age was 62.2 ± 13.0 years. The most common primary site was the oral cavity (38.8 per cent). The mean number of lymph nodes was 30.63 ± 13.9. In total, 17.8 per cent had undergone previous radiotherapy. The mean number of lymph nodes was 33.26 ± 13.27 in patients with no previous radiation exposure and 18.47 ± 9.46 in those with previous radiation treatment.

Lymph node yield from a neck dissection is likely multi-factorial in nature. Previous radiotherapy, the only significant contributor, led to a mean reduction of lymph node yield from 33.3 to 18.5.

Choanal atresia is a congenital obstruction of the posterior nasal aperture. Endoscopic endonasal surgery has led to successful choanal atresia repair. This paper describes our surgical technique using septal mucosal flaps without the need for stenting.

This study comprised a multicentre retrospective review of patient notes. A cross-over septal technique is described, whereby bilateral vertical mucosal incisions are made at the posterior third of the septum, and the atretic plate and posterior vomer are removed. One flap is pedicled superiorly and rotated over the bare skull base and sphenoid bone; the contralateral flap is pedicled inferiorly to cover the exposed vomer remnant and hard palate.

There were 12 patients from 2013 to 2020, aged 0.07–50 years, with a male to female ratio of 1:5. Ten patients had unilateral and two had bilateral choanal atresia. Nine patients had bony choanal atresia, with the remainder mixed.

The cross-over technique for choanal atresia has low morbidity and 100 per cent success in our series. The use of mucoperiosteal flaps to cover exposed bone and minimal instrumentation to the lateral nasal wall reduce post-operative stenosis.

Osteomyelitis of the frontal bone is a rare but devastating complication of frontal sinusitis. Treatment involves aggressive surgery to remove all sequestra in combination with long-term antibiotic therapy. However, systemic antibiotics may struggle to penetrate any remaining infection in devascularised areas, and the morbidity associated with surgical resection of some areas of the skull base is too high. In contrast, locally implanted antibiotics provide a reliable, high concentration of treatment to these areas while also minimising potential systemic side effects. The clinical application of tobramycin beads has primarily been used in orthopaedics as an adjunct to the treatment of tibial osteomyelitis or prosthetic joint infection.

To the best of the authors' knowledge, the two cases discussed here represent the first use of tobramycin antibiotic beads in frontal sinus osteomyelitis secondary to chronic rhinosinusitis.

These cases show promising use of tobramycin beads in recalcitrant frontal osteomyelitis.

Cholesteatomas present a high risk for residual and recurrent disease, and the surveillance of post-operative patients can be challenging. Diffusion-weighted magnetic resonance imaging is becoming the preferred method for investigating recidivism; however, false positive imaging findings increase the risk of patients undergoing unnecessary second look surgery.

This study reports two patients with false positive diffusion restriction associated with cartilage grafts that mimicked cholesteatoma and resulted in second look surgery with no disease found at operation. This study also discusses the related medical literature, including potential causes of abnormal diffusion restriction and methods to negate this.

Caution should be exercised when considering second look surgery in the presence of a cartilage graft and a high confidence of disease clearance. A multi-disciplinary approach is recommended for the operating surgeon to review the images with a radiologist.
