Recent scientific literature has widely described a possible major role of smell dysfunction as a specific symptom of coronavirus disease 2019. This systematic review may provide a more holistic approach to current knowledge of the disease.

A systematic review was completed using Embase, PubMed and Web of Science databases that considered original articles focused on olfactory evaluation in coronavirus disease 2019 patients, published between March and May 2020, in English language.

From the 483 research papers initially identified, 32 original studies were selected, comprising a total of 17 306 subjects with a laboratory confirmed diagnosis of coronavirus disease 2019. Individual study sample sizes ranged from 6 to 6452 patients. This comprehensive analysis confirmed that olfactory disorders represent an important clinical feature in coronavirus disease 2019, with a prevalence of 11–100 per cent in included patients, although there was heterogeneity in terms of assessment tools and population selection criteria.

The results indicate that an accurate clinical evaluation should be carried out using structured questionnaires and tests with olfactory substances.

Tonsillectomy and adenoidectomy have been among the most commonly performed procedures in children for approximately 100 years. These procedures were the first for which unwarranted regional variation was discovered, in 1938. Indications for these procedures have become stricter over time, which might have reduced regional practice variation.

This paper presents a historical review on practice variation in paediatric tonsillectomy and adenoidectomy rates. Data on publication year, region, level of variation, methodology and outcomes were collected.

Twenty-one articles on practice variation in paediatric tonsil surgery were included, with data from 12 different countries. Significant variation was found throughout the years, although a greater than 10-fold variation was observed only in the earliest publications.

No evidence has yet been found that better indications for tonsillectomy and adenoidectomy have reduced practice variation. International efforts are needed to reconsider why we are still unable to tackle this variation.

Advances in immunohistochemistry have spearheaded major developments in our understanding and classification of sinonasal tumours. In the last decade, several new distinct histopathological entities of sinonasal cancer have been characterised.

This review aims to provide a clinical update of the major emerging subtypes for the ENT surgeon and an overview of the management strategies available for this heterogeneous group of pathologies.

Although rare, knowledge of sinonasal neoplasm subtypes has implications for prognosis, treatment strategies and the development of novel therapeutic targets.

This paper discusses the concept of acoustic shock based on a literature review and the results of our own research into cases seen in both clinical and medicolegal practice. With the demise of traditional ‘metal bashing’ and ‘smoke stack’ heavy industries, there has been a decline in the incidence of noise-induced hearing loss and tinnitus in this form of employment. However, with the increasing establishment of call centre work, the emergence of acoustic shock has been noted. Acoustic shock is recognised as a clinical entity distinct from noise-induced hearing loss and acoustic trauma.

This article discusses clinical implications, medicolegal considerations in light of a recent high-profile court case and proposed criteria for diagnosis.

The Nottingham and Nottinghamshire Hospital for Diseases of the Throat, Ear and Nose existed in Nottingham for over 60 years, but there is little knowledge or documentation regarding its existence.

The following resources were searched to find out more about the hospital: the Nottinghamshire Archives; Manuscripts and Special Collections at the University of Nottingham Libraries; and Nottingham Central Library. Information was also obtained from the founders’ relatives.

The hospital was founded in 1886, by Dr Donald Stewart, supported by political and clerical leaders. Initially, it treated out-patients only; in-patients were admitted for surgical treatment from 1905. Suitable accommodation was purchased in 1925, on Goldsmith Street, but required much building extension and alteration. Building restrictions during and following World War II prevented expansion. The National Hospital Survey conducted in 1945 considered the clinical work undertaken to be of a minor character, and recommended closure and amalgamation with the services provided by the Nottingham General Hospital. The hospital closed in 1947.

The specialist hospital was deemed unfit and unsuitable to compete with the comprehensive service provided by the Nottingham General Hospital.

Advances in endoscopic technology have allowed transnasal oesophagoscopy to be used for a variety of diagnostic and therapeutic procedures.

A review of the literature was carried out to look into the extended role of transnasal oesophagoscopy within otolaryngology, using the Embase, Cinahl and Medline databases.

There were 16 studies showing that transnasal oesophagoscopy is safe and cost effective and can be used for removal of foreign bodies, tracheoesophageal puncture, laser laryngeal surgery and balloon dilatation.

This study presents a summary of the literature showing that transnasal oesophagoscopy can be used as a safe and cost-effective alternative or adjunct to traditional rigid endoscopes for therapeutic procedures.

The detrimental systemic effects of cigarette smoking are well established. Though less pronounced in the field of otology, they are proposed to contribute to the global burden of unaddressed hearing loss. Recently, in efforts to stop smoking, individuals have used electronic cigarettes of which the long-term safety data are largely unknown. This study aimed to conduct a systematic review of cigarette smoking and electronic cigarette effects in the field of otology.

Relevant articles were identified by a National Institute for Health and Care Excellence healthcare database literature search and by scanning the references of relevant articles and reviews.

A total of 473 articles were identified, with 43 articles included in the review after trials were excluded.

Cigarette smoking is associated with recurrent otitis media, otitis media with effusion and sensorineural hearing loss in children exposed to second-hand smoke. In adults, it is associated with active and aggressive chronic suppurative otitis media, worse tympanoplasty success rates, increased post-operative complications and sensorineural hearing loss that is more pronounced in the long term and at high frequencies. The effects of e-cigarettes in otology are largely unknown.

Coronavirus disease 2019 has had a dramatic effect on society and healthcare. Preparations were based on predictive models of need, and with uncertainty regarding risk to patients and healthcare workers. Actions taken had both immediate and ongoing ethical impacts. The most obvious of these was the shift in duty of care from individual patients to public health centred ethics and decision making.

In ENT, many procedures are aerosol-generating and so our capacity to provide care will remain significantly reduced. This reduction in capacity may result in difficult choices for patients when optimal care may be replaced by acceptable care. ENT surgeons may also be faced with unaccustomed paternalism when capacity prevents them from acting within the patients’ wishes.

Despite these challenges, the novel uses of technology highlight the desire to preserve and enhance the autonomy of our patients.

ENT surgeons are likely to be at high risk of coronavirus disease 2019 exposure.

A national registry of UK ENT surgeons with suspected or confirmed coronavirus disease 2019 was created with the support of ENT UK. Voluntary entry was made by either the affected individual or a colleague, using a web-based platform.

A four-month data collection period is reported, comprising 73 individuals. Coronavirus disease 2019 was test-confirmed in 35 respondents (47.9 per cent). There was a need for hospitalisation in two cases (2.7 per cent) and tragically one individual died. Symptom onset peaked in March. The majority suspected their exposure to have been in the workplace, with a significant proportion attributing their disease to a lack of personal protective equipment at a time before formal guidance had been introduced.

The registry suggests that a significant number of ENT clinicians in the UK have contracted coronavirus disease 2019, and supports the need for tailored personal protective equipment guidance and service planning.

Binaural hearing is facilitated by neural interactions in the auditory pathway. Ageing results in impairment of localisation and listening in noisy situations without any significant hearing loss. The present study focused on comparing the binaural encoding of a speech stimulus at the subcortical level in middle-aged versus younger adults, based on speech-evoked auditory brainstem responses.

Thirty participants (15 young adults and 15 middle-aged adults) with normal hearing sensitivity (less than 15 dB HL) participated in the study. The speech-evoked auditory brainstem response was recorded monaurally and binaurally with a 40-ms /da/ stimulus. Fast Fourier transform analysis was utilised.

An independent sample t-test revealed a significant difference between the two groups in fundamental frequency (F0) amplitude recorded with binaural stimulation.

The present study suggested that ageing results in degradation of F0 encoding, which is essential for the perception of speech in noise.

Accessory nerve palsy affects a proportion of patients following neck dissection, and results in shoulder dysfunction and regional pain. This project aimed to establish the evidence supporting post-operative physiotherapy for the shoulder following neck dissection.

A systematic review was conducted of prospective trials investigating the efficacy of rehabilitation for shoulder or upper limb dysfunction and pain following any type of neck dissection.

A total of 820 papers were identified; through a staged review process, 7 trials were found that fulfilled the inclusion criteria. These included three randomised, controlled trials and four non-randomised studies. Five out of the seven trials demonstrated a statistically significant benefit of physiotherapy.

Current evidence shows a benefit from physiotherapy in patients with shoulder dysfunction following neck dissection. Some evidence suggests progressive resistance is superior to other types of physiotherapy. Long-term benefit and cost efficacy have not been studied.

Cold dissection is the most commonly used tonsillectomy technique, with low post-operative haemorrhage rates. Coblation is an alternative technique that may cause less pain, but could have higher post-operative haemorrhage rates.

This study evaluated the peri-operative outcomes in paediatric tonsillectomy patients by comparing coblation and cold dissection techniques.

A systematic review was conducted of all comparative studies of paediatric coblation and cold dissection tonsillectomy, up to December 2018. Any studies with adults were excluded. Outcomes such as pain, operative time, and intra-operative, primary and secondary haemorrhages were recorded.

Seven studies contributed to the summative outcome. Coblation tonsillectomy appeared to result in less pain, less intra-operative blood loss (p < 0.01) and a shorter operative time (p < 0.01). There was no significant difference between the two groups for post-operative haemorrhage (p > 0.05).

The coblation tonsillectomy technique may offer better peri-operative outcomes when compared to cold dissection, and should therefore be offered in paediatric cases, before cold dissection tonsillectomy.

Ménière's disease is a debilitating chronic peripheral vestibular disorder associated with psychiatric co-morbidities, notably depression.

Database searches were performed to identify studies that assessed depression in Ménière's disease. Metrics used to diagnose depression were extracted, along with the prevalence of depression in each study.

Fifteen studies from 8 different countries reported on 6587 patients. The weighted average age was 55.3 years (range, 21–88 years). Depression was measured by eight different scales, with Zung's Self-Rating Depression Scale used most often. A weighted proportion of 45.9 per cent of patients (confidence interval = 28.9–63.3) were depressed. Weighted averages (± standard deviations) of Beck's Depression Inventory and the Illness Behavior Questionnaire – Dysphoria were 8.5 ± 7.9 and 2.4 ± 1.7, respectively.

The prevalence of depression in patients with Ménière's disease is nearly 50 per cent. Treating otolaryngologists should have a low threshold to screen and refer appropriately. Identifying and treating depression should allow for improvement of overall quality of life in patients with Ménière's disease.

Vertigo and dizziness are frequent symptoms in patients at out-patient services. An accurate diagnosis for vertigo or dizziness is essential for symptom relief; however, it is often challenging. This study aimed to identify differences in diagnoses between primary-care physicians and specialised neurotologists.

In total, 217 patients were enrolled. To compare diagnoses, data was collected from the reference letters of primary-care physicians, medical questionnaires completed by patients and medical records.

In total, 62.2 per cent and 29.5 per cent of the patients were referred by otorhinolaryngologists and internists, respectively. The cause of vertigo or dizziness and diagnosis was missing in 47.0 per cent of the reference letters. In addition, 67.3 per cent of the diagnoses by previous physicians differed from those reported by specialised neurotologists.

To ensure patient satisfaction and high quality of life, an accurate diagnosis for vertigo or dizziness is required; therefore, methods or materials to improve the diagnostic accuracy are needed.

An objective evaluation of coronavirus disease 2019 in the first days of infection is almost impossible, as affected individuals are generally in home quarantine, and there is limited accessibility for the operator who should perform the test. To overcome this limitation, a recently validated psychophysical self-administered test was used, which can be performed remotely in the assessment of early-stage coronavirus disease 2019 patients.

Olfactory and gustatory functions were objectively assessed in 300 patients in the first 7 days from coronavirus disease 2019 symptom onset.

Seventy per cent of the patients presented olfactory and/or gustatory disorders. The dysfunctions detected were mainly complete anosmia (47 per cent) or ageusia (38 per cent). A significant correlation was found between taste dysfunction and female gender (odds ratio = 1.936, p = 0.014) and fever (odds ratio = 2.132, p = 0.003).

The psychophysical evaluation protocol proposed is an effective tool for the fast and objective evaluation of patients in the early stages of coronavirus disease 2019. Chemosensitive disorders have been confirmed to be frequent and early symptoms of the coronavirus infection, and, in a significant number of cases, they are the first or only manifestation of coronavirus disease 2019.

The concept of endoscopic diagnosis and procedures on the nasal cavity had been investigated for several decades in Europe in the early part of the twentieth century. It was Prof Walter Messerklinger and his assistant, Heinz Stammberger, with US colleague, David Kennedy, who brought the science and technique of functional endoscopic sinus surgery to the wider world.

The author, an English-speaking surgeon, was present at this movement from the commencement of its propagation, and has recorded the remarkable ascendency of this technique throughout the world.

The technique revolutionised the diagnosis and management of intranasal, sinus and intracranial conditions.

Recent developments in magnetic resonance imaging have enabled demonstration of endolymphatic hydrops, and the clinical application of these imaging studies in Ménière's disease is being explored.

To evaluate our centre's experience to date of hydrops magnetic resonance imaging in patients with episodic vertigo.

Magnetic resonance imaging was performed using a high-resolution three-dimensional fluid-attenuated inversion recovery sequence on a 3 Tesla scanner at 4 hours following double-dose gadolinium administration.

The study included 31 patients, 28 of whom had a clinical diagnosis of Ménière's disease. In unilateral Ménière's disease, magnetic resonance imaging was able to lateralise endolymphatic hydrops to the clinically symptomatic ear in all cases. Mild hydrops was often seen in clinically asymptomatic ears.

There is a good correlation between the clinical symptoms and lateralisation of hydropic changes on magnetic resonance imaging. Further refinements of imaging techniques and grading system will likely improve the diagnostic accuracy and clinical utilisation of hydrops magnetic resonance imaging.
