Eustachian tube dysfunction is prevalent in both paediatric and adult populations. Current clinical guidelines recommend observation over topical intranasal corticosteroids for Eustachian tube dysfunction management, which remains controversial. This study aimed to systematically review randomised, controlled trials assessing topical intranasal corticosteroid efficacy in Eustachian tube dysfunction, and analyse effect through tympanometric normalisation.

PubMed, EMBASE, Web of Science and Cochrane Library databases were searched. All randomised, controlled trials assessing intranasal corticosteroids in adult or paediatric Eustachian tube dysfunction patients were included. A meta-analysis of proportions was used to evaluate tympanogram normalisation.

Of 330 results, eight randomised, controlled trials met inclusion criteria and underwent qualitative data synthesis and risk-of-bias analysis. Meta-analysis of tympanometry data from four eligible trials (n = 512 ears) revealed no significant difference in tympanometric normalisation between intranasal corticosteroids and control (odds ratio 1.21, 95% confidence interval 0.65–2.24).

Study results do not strongly support intranasal corticosteroids for Eustachian tube dysfunction. Data were limited, emphasising the need for larger, higher quality, randomised, controlled trials.

Otoscopic skills are essential for ENT doctors. Early-stage doctors develop skills whilst treating patients, with minimal teaching, potentially increasing risk to patients. Simulation allows skill development without patient risk; however, simulation often requires subjective expert review of technique. This study compared enhanced low-fidelity simulation with performance feedback against standard simulation using a basic otoscopy skills simulator.

Two low-fidelity ear simulators were created: a basic model without feedback and an enhanced model which alarms when the aural instrument tip touches the canal wall. Participants were evaluated in a randomised crossover pilot study, using both models to assess whether objective feedback reduced tip touches.

The enhanced simulator reduced tip touches more than the control model, suggesting better and more sustained skill uptake. Participants reported that the enhanced model improved learning.

Enhanced low-fidelity models provide a low-cost opportunity to improve otoscopy skills without patient risk or the need for subjective expert feedback.

To describe the post-operative complications and audiological results related to percutaneous bone-anchored hearing devices.

A retrospective review was conducted of 44 patients with bilateral conductive or mixed hearing loss who were implanted with unilateral Baha Connect or Ponto devices. A generalised linear model for repeated measurements was used.

Twenty patients were Baha Connect users, and 24 were implanted with Ponto devices. Twenty-seven patients experienced complications. No fewer complications were found in the group of patients using longer abutments. When we compared the frequency of complications between Ponto and Baha Connect users, there was no statistically significant difference (p = 0.90). Free-field hearing thresholds were statistically significantly improved when we compared pre- and post-operative results (p < 0.001). Average speech perception also improved (p < 0.001).

Despite percutaneous bone-anchored hearing devices having a high rate of complications, they provide significant audiological benefits.

Desmoid tumours (aggressive fibromatosis) are rare, locally invasive, benign tumours. The following case represented a diagnostic challenge, because of the uncommon nature of the lesion.

A 26-year-old woman, who had previously undergone middle-ear surgery for cholesteatoma, presented with a painful swelling involving the post-auricular area and the conchal bowl. Initially, it was believed to be an infective process related to the surgery or an unusual cholesteatoma recurrence. Following investigations, which involved imaging and histology, the swelling was diagnosed as a desmoid tumour, and the patient received chemotherapy.

Two incidences of paediatric desmoid tumours affecting the ear have been described in the literature, but there is no previous report of a desmoid tumour related to ear surgery. Desmoid tumours have, however, been reported following trauma, including surgery.

Politzer's tuning fork test is a little-known special examination with a chequered history.

This paper gives Politzer's original description, and explains how he intended it to be used.

The historiographical research in this study is based on primary references. Secondary documentation is only cited when it is necessary to substantiate any historical argument.

After the apparent disappearance of Politzer's tuning fork test from the otological scene in the 1950s, its consequent resurrection was not what it seemed. This story underlines the need for a standardisation of otological nomenclature, particularly when eponyms are used.

To establish the relationship between endoscope temperatures and luminosity with a variety of light source types, endoscope ages, endoscope sizes, angles and operative distance in transcanal endoscopic ear surgery.

Transcanal endoscopic ear surgery was simulated in an operating theatre using 7 mm plastic suction tubing coated in insulating tape. An ATP ET-959 thermometer was used to record temperatures, and a Trotec BF06 lux meter was used to measure luminosity. Luminosity and temperature recordings were taken at 0 mm and 5 mm from the endoscope tip.

Thermal energy transfer from operating endoscopes is greatest when: the light intensity is high, there is a light-emitting diode light source and the endoscope is touching the surface. Additionally, larger-diameter endoscopes, angled endoscopes and new endoscopes generated greater heat.

It is recommended that operative light intensity is maintained at the lowest level possible, and that the surgeon avoids contact between patient tissues and the endoscope tip.

Management of tympanic membrane perforations is varied. This study aimed to better understand current practice patterns in myringoplasty and type 1 tympanoplasty.

An electronic questionnaire was distributed to American Academy of Otolaryngology – Head and Neck Surgery members. Practice patterns were compared in terms of fellowship training, practice length, practice setting, paediatric case frequency and total cases per year.

Of the 321 respondents, most were comprehensive otolaryngologists (60.4 per cent), in private practice (60.8 per cent), with a primarily adult practice (59.8 per cent). Fellowship training was the factor most associated with significant variations in management, including pre-operative antibiotic usage (p = 0.019), contraindications (p < 0.001), approach to traumatic perforations (p < 0.001), use of local anaesthesia (p < 0.001), graft material (p < 0.001), tympanoplasty technique (p = 0.003), endoscopic assistance (p < 0.001) and timing of post-operative audiology evaluation (p = 0.003).

Subspecialty training appears to be the main variable associated with significant differences in peri-operative decision-making for surgical repair of tympanic membrane perforations.

In the wake of the 2019 coronavirus disease pandemic, elective cases and opportunities for clinical application have decreased, and the need for useful simulation models has become more apparent for developing surgical skills. A novel myringotomy with ventilatory tube insertion simulation model was created.

Residents across all levels at our institution participated in the simulation. Participants were evaluated in terms of: time of procedure, microscope positioning, cerumen removal, identification of middle ear effusion type, canal wall trauma, tympanic membrane damage and tube placement.

Eleven residents participated. Scores ranged from 14 to 34, out of a maximum of 40. The average score among junior and senior residents was 24 and 31, respectively. The simulation was felt to be representative of the operating theatre experience.

This study demonstrates a low-cost simulation model that captures several important, nuanced aspects of myringotomy with tube insertion, often overlooked in previously reported simulations.

Retraction pockets are collapsed segments of the tympanic membrane. Their formation is associated with a disruption in middle-ear ventilation pathways, leading to the loss of organised collagen of the tympanic membrane. There are several approaches in treating retraction pockets, which aim either to improve ventilation or repair the retraction pockets themselves.

A review of the literature regarding the classification and associated management of retraction pockets was conducted, using Medline and Cochrane Library databases, with the addition of our institution's experience in undertaking novel techniques.

All the current classification systems fail to guide treatment or prognosticate the disease. Commonly, an initial conservative approach is suggested for early stages, with no clear indication regarding when a surgical solution should be offered. There are conflicting data concerning the effectiveness of these treatments in terms of disease prevention, recurrence and hearing outcomes.

Minimally invasive approaches utilising novel techniques may be key to reducing peri-operative morbidity and improving the overall patient experience.

Necrotising otitis externa is an invasive, infective condition, with minimal evidence underpinning its diagnosis and management. This work aimed to analyse literature from the past decade, to identify emerging themes and important topics for future research.

A robust literature search and review were conducted by two researchers. Sixty studies were filtered into the final review. A grounded theory approach was used to identify core themes. Data within these themes formed the basis of the review.

There is no consensus regarding a clinical definition or outcome measures of necrotising otitis externa, and there exists no level 1, 2 or 3 evidence to diagnose, investigate, monitor or treat necrotising otitis externa. Emerging themes in the literature direct researchers to important topics for future clinical trials, including risk factors, microbiological culture, management strategies and radiology.

In order to optimise understanding and management of necrotising otitis externa, future research requires robust clinical trials and consistently reported outcome measures.

Sudden hearing loss, or progressive hearing loss occurring over months to years, are well-established presentations. However, little is described in the medical literature on how to approach patients presenting with a rapidly progressive hearing loss occurring over weeks. This study aimed to evaluate the clinical significance of patients presenting with rapidly progressive hearing loss.

A case of rapidly progressive hearing loss occurring over 12 weeks is presented. A PubMed literature review was performed to determine the evidence-based differential diagnoses for rapidly progressive hearing loss.

Fifteen causes were identified for rapidly progressive hearing loss: intracranial aetiologies (meningioma, lymphoma, metastatic deposit, cavernous angioma, meningitis, superficial siderosis); paraneoplastic syndrome (small cell lung carcinoma, thymoma); inflammatory or autoimmune disorders (autoimmune inner-ear disease, sarcoidosis, vasculitis, Sjögren's syndrome); infective disorders (syphilis, human immunodeficiency virus); and medication-induced causes.

Rapidly progressive hearing loss should be considered a ‘red flag’ symptom that warrants urgent action. Most causes are systemic or sinister in nature, and the patient's hearing loss can potentially be reversed.

Globally, South Asia has the highest proportion of disabling hearing loss. There is a paucity of data exploring the associated hearing loss and disability caused by chronic middle-ear disease in South Asia in the setting of surgical outreach. This study aimed to measure disability using the World Health Organization Disability Assessment Schedule 2.0 in patients undergoing ear surgery for chronic middle-ear disease in an ear hospital in Nepal.

The World Health Organization Disability Assessment Schedule 2.0 was translated into Nepali and administered by interview to patients before ear surgery, and results were correlated with pre-operative audiograms.

Out of a total of 106 patients with a mean age of 23 years, the mean World Health Organization Disability Assessment Schedule 2.0 score was 17.7, and the highest domain scores were for domain 6 ‘participation in society’ at a score of 34. There was a positive correlation of World Health Organization Disability Assessment Schedule 2 score with hearing level (r = 0.46).

Patients with ear disease in Nepal have had their disability measured using the World Health Organization Disability Assessment Schedule 2.0. Our study demonstrated a correlation between impaired hearing and disability in a surgical outreach context, which was an expected but not previously reported finding.

The application of a 4K display resolution three-dimensional exoscope system (Vitom 3D) was evaluated to determine the feasibility of adopting the system in ENT surgery in the coronavirus disease 2019 era and beyond.

Eighteen ENT surgeons performed structured otological tasks on fresh-frozen sheep heads using the Vitom 3D. Structured feedback of the participants’ experience was analysed.

Seventy-four per cent and 94 per cent of participants reported that the Vitom 3D was ergonomic and comfortable to use respectively. Whilst colour fidelity and image quality were very good, 50 per cent of participants reported image distortion and pixilation at the highest magnification. All participants agreed that there was an increased educational value to exoscope technology. Half the participants preferred the microscope over the Vitom 3D for fine otological work, which may reflect the learning curve.

The Vitom 3D exoscope is a promising and viable alternative for performing otological surgery when using full personal protective equipment in the coronavirus disease 2019 era.

Mastoid surgery is an aerosol-generating procedure that involves the use of a high-speed drill, which produces a mixture of water, bone, blood and tissue that may contain the viable coronavirus disease 2019 pathogen. This potentially puts the surgeon and other operating theatre personnel at risk of acquiring the severe acute respiratory syndrome coronavirus-2 from contact with droplets or aerosols. The use of an additional drape designed to limit the spread of droplets and aerosols has been described; such drapes include the ‘Southampton Tent’ and ‘OtoTent’.

To evaluate the use of a novel drape ‘tent’ that has advantages over established ‘tent’ designs in terms of having: (1) a CE marking; (2) no requirement for modification during assembly; and (3) no obstruction to the surgical visual field.

During mastoid surgery, the dispersion of macroscopic droplets and other particulate matter was confined within the novel drape ‘tent’. Use of this drape ‘tent’ had no adverse effects upon the surgeon's manual dexterity or efficiency, the view of the surgical field, or the sterility. Hence, our findings support its use during mastoid surgery in the coronavirus disease 2019 era.

The introduction of endoscopic ear surgery has implications for the training of otolaryngology residents.

To report on the status of endoscopic ear surgery and assess the effects of this new technology on otolaryngology training in Singapore, from the residents’ perspective.

An anonymous survey was conducted amongst all Singaporean otolaryngology residents. Residents’ exposure to, and perceptions of, endoscopic ear surgery were assessed.

Residents from institutions that practise endoscopic ear surgery were more positive regarding its efficacy in various otological surgical procedures. Of residents in programmes with exposure to endoscopic ear surgery, 82.4 per cent felt that its introduction had adversely affected their training, with 88.3 per cent of residents agreeing that faculty members’ learning of endoscopic ear surgery had decreased their hands-on surgical load. Both groups expressed desire for more experience with endoscopy.

The majority of residents view endoscopic ear surgery as an expanding field with a potentially negative impact on their training. Mitigating measures should be implemented to minimise its negative impact on residents’ training.

The field of otology is increasingly at the forefront of innovation in science and medicine. The inner ear, one of the most challenging systems to study, has been rendered much more open to inquiry by recent developments in research methodology. Promising advances of potential clinical impact have occurred in recent years in biological fields such as auditory genetics, ototoxic chemoprevention and organ of Corti regeneration. The interface of the ear with digital technology to remediate hearing loss, or as a consumer device within an intelligent ecosystem of connected devices, is receiving enormous creative energy. Automation and artificial intelligence can enhance otological medical and surgical practice. Otology is poised to enter a new renaissance period, in which many previously untreatable ear diseases will yield to newly introduced therapies.

This paper speculates on the direction otology will take in the coming decades.

Making predictions about the future of otology is a risky endeavour. If the predictions are found wanting, it will likely be because of unforeseen revolutionary methods.

Evidence from the literature shows that clinicians’ knowledge of rules and legislation surrounding driving can often be poor. A closed-loop audit was conducted to gauge the level of driving advice given to patients with dizziness.

The clinical notes of 100 patients referred to the vertigo clinic at a tertiary referral centre were retrospectively searched for evidence of driving advice. Education sessions were undertaken and a patient information leaflet was developed before a second cycle of the audit.

The proportion of patients having documented evidence of receiving driving advice increased from 6.3 per cent to 10.4 per cent. It is therefore clear that, despite this improvement, a significant proportion of patients’ notes did not contain documentation about driving. This is likely because of many reasons, including individual interpretation by clinicians. This paper provides a reminder of the rules, and discusses their interpretation and implementation in an increasingly medicolegal environment.

All patients undergoing tympanomastoid surgery should be assessed post-operatively for a ‘dead ear’; however, tuning forks are frequently inaccessible.

To demonstrate that smartphone-based vibration applications provide equivalent accuracy to tuning forks when performing Weber's test.

Data were collected on lay participants with no underlying hearing loss. Earplugs were used to simulate conductive hearing loss. Both the right and left ears were tested with the iBrateMe vibration application on an iPhone and using a 512 Hz tuning fork.

Occluding the left ear, the tuning fork lateralised to the left in 18 out of 20 cases. In 20 out of 20 cases, sound lateralised to the left with the iPhone (chi-square test, p = 0.147). Occluding the right ear, the tuning fork lateralised to the right in 19 out of 20 cases. In 19 out of 20 cases, sound lateralised to the right with the iPhone (chi-square test, p > 0.999).

Smartphone-based vibration applications represent a viable, more accessible alternative to tuning forks when assessing for conductive hearing loss. They can therefore be utilised on the ward round, in patients following tympanomastoid surgery, for example.

Facial nerve paresis is rare following cochlear implantation. Mechanisms underlying delayed-onset facial paresis are poorly understood. This paper describes the case of a patient who developed facial nerve paresis three years after implantation. A literature review was performed with the aim of identifying any similar cases.

The patient case is reported, and the literature reviewed using PubMed, Embase and Ovid databases.

The literature review revealed that the vast majority of delayed-onset facial nerve paresis cases occur within the first month of implantation. Only two other cases occurring years after device implantation were identified. Although potential causative factors have been suggested, as in our case this phenomenon may be idiopathic.

Prognosis for recovery of late-onset facial nerve paresis seems promising, despite the unfortunate requirement for device explantation in all previous cases including our own.

Oesophageal disorders and osteonecrosis of the jaw are recognised complications of the commonly prescribed medication bisphosphonate. Despite these diagnoses being seen comparatively frequently within the ENT clinic, osteonecrosis of the external ear is a less well reported complication.

The current literature is reviewed and our experience with six cases of bisphosphonate-related ear canal osteonecrosis is presented.

Six cases were identified as suffering from ear canal osteonecrosis as a result of bisphosphonate treatment. One of our cases suffered bilateral ear canal osteonecrosis after only 20 months of oral alendronic acid treatment. Management ranged from bisphosphonate cessation and topical treatment, to surgical debridement in the operating theatre.

Bisphosphonate-related ear canal osteonecrosis is undoubtedly under-diagnosed. For such a commonly prescribed medication, the risks and side effects of bisphosphonate should be better known and long-term treatment should be avoided if possible.
