This study aimed to assess the olfactory recovery rates and patterns in a cohort of coronavirus disease 2019 positive patients, and to investigate the clinical predictors of poor long-term olfactory restoration.

An observational retrospective study was conducted on 146 patients between September 2020 and January 2021 at a tertiary referral hospital. Coronavirus disease 2019 positive patients with olfactory dysfunction were sent a modified version of the COVID-19 Anosmia Reporting Tool for Clinicians via e-mail.

The difference in median recovery time between complete recovery and incomplete or no recovery was statistically significant. On multivariate analysis, the only significant factor associated with incomplete or no recovery was anosmia duration.

After a mean time of 5.6 months from severe acute respiratory syndrome coronavirus-2 infection, persistent olfactory disorders were self-reported in 36.7 per cent of patients. Complete recovery was more likely to occur within 15 days. Given the high prevalence of coronavirus disease 2019, a large number of patients are expected to suffer from long-term olfactory morbidity.

This study aimed to report the changes made to ENT placements across the UK in response to the pandemic and their impact on student experience.

A questionnaire eliciting how ENT placements were provided before and after coronavirus disease 2019 was disseminated amongst Student and Foundation Doctors in Otolaryngology representatives.

Thirty-eight respondents from 27 medical schools across the UK completed the survey (response rate of 90 per cent). Twenty-nine of the 38 respondents (76 per cent) reported a change in ENT placements in response to the pandemic. Six of the 38 students (16 per cent) remained satisfied with their ENT placements, as compared to 12 students prior to the pandemic (32 per cent).

There is considerable variability in how medical schools responded to the pandemic. Most medical schools placed students into smaller groups, with less direct contact in the hospital. These changes resulted in lower student satisfaction. The increased emphasis on e-learning underscores the need for high quality e-learning materials to promote learning throughout the pandemic and in the future.

The arrival of the coronavirus disease 2019 pandemic disrupted life suddenly and forcefully, and healthcare systems around the world are still struggling to come to terms with it. This paper reviews the impact of the pandemic on ENT practice and training.

The present manuscript was developed as a narrative review to examine the role of otorhinolaryngologists in the management of the pandemic, and assess its impact on practice and training in the specialty.

Otorhinolaryngologists handle secretions of organs implicated in disease transmission, leaving them particularly vulnerable even while performing simple procedures. Although the pandemic increased skill expectations, it simultaneously reduced learning opportunities for trainees. In addition, attention to emergencies has been delayed. Further, the suspension of elective procedures has affected patients with malignancies.

While planning service resumption, provisions need to be made for protective equipment and training; improving teleconsultation services will help provide sustainable care during further waves.

Otological complications are considered early symptoms of severe acute respiratory syndrome coronavirus-2; however, it is unknown how long these symptoms last and whether the virus leaves any hearing disorders post-recovery.

This prospective cohort study comprised 31 mild or moderate confirmed coronavirus disease 2019 patients and 26 age-matched control peers (21–50 years old). Patients were questioned about their otological symptoms, and their hearing status was assessed during one month post-diagnosis.

Patients showed a significantly higher rate of otological symptoms (hearing loss, ear fullness, ear pain, dizziness or vertigo, communication difficulties, and hyperacusis) versus the control group (p ≤ 0.022). The symptoms resolved early, between 2 and 8 days after their appearance. No significant differences were observed between the two groups in pure tone and extended high-frequency audiometry, transient evoked otoacoustic emissions, distortion product otoacoustic emissions, or auditory brainstem response following recovery.

The findings indicate that, in mild to moderate coronavirus disease 2019 cases, otological symptoms resolve within a week, and the virus has no lasting impact on the auditory system.

To report the one-year findings of the UK national registry of ENT surgeons with suspected or confirmed coronavirus disease 2019, and the results of a survey on the coronavirus disease 2019 experience of UK ENT trainees.

An online registry was created in April 2020. A separate survey was circulated electronically to all members of the Association of Otolaryngologists in Training.

The registry recorded 98 clinicians with confirmed or suspected coronavirus disease 2019. The majority of infections were reported in the first wave of spring 2020. Two ENT surgeons were hospitalised and one died. The majority suspected workplace exposure, with a significant proportion attributing this to a lack of personal protective equipment at a time before formal guidance had been introduced. Of the ENT trainees surveyed, almost one-third believed that they had contracted coronavirus disease 2019.

This highlights the importance of ongoing risk-reduction measures, including optimal personal protective equipment and vaccination.

Patients with coronavirus disease vaccine associated lymphadenopathy are increasingly being referred to healthcare services. This work is the first to report on the incidence, clinical course and imaging features of coronavirus disease vaccine associated cervical lymphadenopathy, with special emphasis on the implications for head and neck cancer services.

This was a retrospective cohort study of all patients referred to our head and neck cancer clinics between 16 December 2020 and 12 March 2021. The main outcomes measured were the proportion of patients with vaccine-associated cervical lymphadenopathy, and the clinical and imaging characteristics.

The incidence of vaccine-associated cervical lymphadenopathy referrals was 14.8 per cent (n = 13). Five patients (38.5 per cent) had abnormal-looking enlarged and rounded nodes with increased vascularity. Only seven patients (53.9 per cent) reported full resolution within an average of 3.1 ± 2.3 weeks.

Coronavirus disease vaccine associated cervical lymphadenopathy can mimic malignant lymphadenopathy and therefore might prove challenging to diagnose and manage correctly. Healthcare services may encounter a significant increase in referrals.

To study the impact of telemedicine on patient outcomes during a nationwide lockdown to halt the spread of coronavirus disease 2019.

A retrospective study was conducted to examine telemedicine consultations of newly referred patients over 7 days during a national lockdown. Overall outcomes of telephone clinics were recorded, measured as either patient discharged, imaging requested, patient referred to another specialty, further telephone follow up required, patient initiated follow up or face-to-face appointment required.

Data were collected from 104 patients. Outcomes showed that 17 patients were discharged, 15 had imaging requested, 11 were referred to another specialty, 11 had further telemedicine appointments, 31 had patient-initiated follow up and 19 received face-to-face appointments. Overall, 57 per cent of patients avoided hospital visits and 17 per cent required face-to-face appointments. Of higher risk patients, 49 per cent were managed remotely. After eight months, no significant morbidity or mortality was reported.

Almost half of the higher risk patients avoided a hospital visit. The majority of patients were managed remotely, and thus the risk and spread of infection were reduced. Telemedicine has an important role in ENT out-patients.

There has been a recent deluge of coronavirus disease 2019 associated mucormycosis in our country. It affects the paranasal sinuses; however, it has a rapid extrasinus progression (the orbit being most common), which can be fatal if not detected early. It may meander into the orbit through various foramina without frank bone destruction.

This paper reviews the various gateways of the spread of coronavirus disease 2019 associated mucormycosis to the orbit, even before advent of bone destruction or ocular symptoms. Plausible pathways of invasion and subtle imaging findings are depicted, to enable an early diagnosis.

Relevant anatomy and imaging examples have been illustrated to familiarise the surgeons with various routes of coronavirus disease 2019 associated mucormycosis spread to the orbit. Emphasis is laid on searching for subtle imaging findings for the detection of early orbital invasion.

Early detection and extension of coronavirus disease 2019 associated mucormycosis is facilitated by knowledge of its gateways of spread, which aids the surgeon in prognostication and planning of the surgical approach.

The primary goal of this study was to evaluate the association between olfactory dysfunction or taste impairment and disease severity and radiological findings in coronavirus disease-2019. The secondary goal was to assess the prevalence, severity and course of olfactory dysfunction or taste impairment in patients with coronavirus disease 2019.

This prospective observational cohort study evaluated patients hospitalised with coronavirus disease 2019 between April 1 and 1 May 2020. Olfactory dysfunction and taste impairment were evaluated by two questionnaires. Chest computed tomography findings and coronavirus disease-2019 severity were assessed.

Among 133 patients, 23.3 per cent and 30.8 per cent experienced olfactory dysfunction and taste impairment, respectively, and 17.2 per cent experienced both. The mean age was 56.03 years, and 64.7 per cent were male and 35.3 per cent were female. No statistically significant association was found between olfactory dysfunction (p = 0.706) and taste impairment (p = 0.35) with either disease severity or chest computed tomography grading.

Olfactory dysfunction or taste impairment does not have prognostic importance in patients with coronavirus disease 2019.

Despite the rapidly emerging reports of olfactory dysfunction amongst adult patients with coronavirus disease 2019, cases involving children and adolescents are scarcely reported. The literature was reviewed to elucidate olfactory dysfunction amongst children and adolescents with coronavirus disease 2019.

A search of the literature published from 1 December 2019 to 30 April 2021 was conducted using four databases, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The search was performed over one month (May 2021).

Only 9 articles were identified, with a total of 316 laboratory confirmed coronavirus disease 2019 positive children and adolescents, of whom 156 reported olfactory dysfunction. Four studies reported olfactory dysfunction based on subjective tests; four studies carried out objective assessment. Most studies reported on olfaction recovery.

The literature review revealed an olfactory dysfunction rate of 49 per cent amongst children and adolescents with coronavirus disease 2019. Persistence of olfactory dysfunction was reported in 7.1 per cent of the patients. Further studies involving objective measures need to be carried out in children and adolescents with coronavirus disease 2019.

Treatment of coronavirus disease 2019 infection can result in immunosuppression. Rhino-orbital-cerebral mucormycosis is a frequent co-infection, even after recovery.

An ambispective interventional study was conducted of 41 coronavirus patients with rhino-orbital-cerebral mucormycosis at a tertiary care centre from March to May 2021.

There were 28 males and 13 females with a mean age of 48.2 years (range, 21–68 years). Twelve had long-standing diabetes mellitus and 28 had been recently diagnosed. Thirty-six had received systemic corticosteroids for coronavirus disease 2019. Nasal signs were present in 95 per cent of patients, ophthalmic symptoms and signs in 87 per cent, palatal necrosis in 46.3 per cent, facial signs in 24.3 per cent, nerve palsies in 60.9 per cent, and intracranial involvement in 21.9 per cent. Treatment with amphotericin B was based on clinical features and co-morbidities. Endonasal debridement was performed in 51.2 per cent of patients, total maxillectomy in 14.6 per cent and orbital exenteration in 9.7 per cent. At the last follow up, 37 patients (90.24 per cent) were on antifungal therapy; 4 (9.75 per cent) did not survive.

Early detection may improve survival. Follow up of high-risk patients after coronavirus disease 2019 infection is paramount.

To outline the impact on quality of life in coronavirus disease 2019 patients with olfactory dysfunction.

Five databases were searched for articles referring to the impact on quality of life in coronavirus disease 2019 patients with olfactory dysfunction. The search was conducted for the period from November 2019 to April 2021. The search was conducted over one month (May 2021).

Four studies that met the objective were included. Altogether, there were 1045 patients. Various questionnaires were used to assess quality of life. Overall, the quality of life deficit affected 67.7 per cent of patients. Quality of life domains investigated include overall quality of life (four studies), food and taste dysfunction (two studies), mental health (two studies), cognitive function (one study), functional outcome (one study) and safety domains (one study).

Quality of life deficit was reported to be 67.7 per cent among coronavirus disease 2019 patients with olfactory dysfunction. The high prevalence of persistent olfactory dysfunction prompts more serious research, as the long-standing consequences of olfactory dysfunction are detrimental.

This study aimed to explore the impact of the coronavirus disease 2019 pandemic and postponement of elective surgical procedures for profoundly deaf patients awaiting cochlear implantation.

Open-ended questionnaires were sent to all adult patients awaiting cochlear implantation surgery. Qualitative analysis was performed using a grounded theory approach.

Participants described a primarily negative impact on wellbeing from the surgery delay, expressing feelings of isolation or loneliness. Low mood, depression or hopelessness were commonly expressed by elderly participants; frustration and anxiety were described by young adults. Participants described a negative impact on their general daily life, describing difficulties communicating with facemasks and struggles with reliance on telephone communication because of social distancing. Despite these significant psychosocial challenges, only a minority described adaptive coping strategies.

Profoundly deaf patients may be at greater psychosocial risk because of unique challenges from their hearing disability. Our findings can be used to develop evidence-driven strategies to improve communication, wellbeing and quality of life.

This study aimed to compare treatment outcomes in patients with laryngeal and tracheal stenosis treated during and prior to the coronavirus disease 2019 pandemic period.

Patients treated for laryngotracheal lesions with impending airway compromise during the active pandemic period were matched with those treated for similar lesions in the preceding years in a monocentric tertiary hospital setting.

During the pandemic period of 55 days, 31 patients underwent 47 procedures. Seven patients (2 children, 5 adults) had open airway surgery, and one had an operation-specific complication. Twenty-four patients (10 children, 14 adults) underwent 40 endoscopic interventions without any complications. Operation specific results during and prior to the pandemic were comparable.

The management strategy in patients with laryngotracheal lesions and impending airway compromise should not be altered during periods of risk from coronavirus disease 2019. Avoiding a tracheostomy by performing primary corrective surgery or proceeding with a definitive decannulation would be beneficial in these patients to reduce the risk of contagion.

This case series, conducted during the coronavirus disease 2019 pandemic, investigates the impact of leaving aural foreign bodies in situ for a prolonged period of time, including the risk of complications and success rates of subsequent removal attempts.

A retrospective study of aural foreign body referrals over a six-month period was carried out.

Thirty-four patients with 35 foreign bodies were identified (6 organic and 29 inorganic). The duration of foreign bodies left in situ ranged from 1 to 78 days. Four patients suffered from traumatic removal upon initial attempts. First attempts made by non-ENT specialists (68.8 per cent) all failed and were associated with a high risk of trauma (36.4 per cent).

Because of the coronavirus disease 2019 pandemic, this is the first case series to specifically investigate the relationship between the duration of aural foreign bodies left in situ and the risk of complications. Our data suggest that prolonged duration does not increase the incidence of complications.

This study aimed to assess olfactory dysfunction in patients at six months after confirmed coronavirus disease 2019 infection.

Coronavirus disease 2019 positive patients were assessed six months following diagnosis. Patient data were recoded as part of the adapted International Severe Acute Respiratory and Emerging Infection Consortium Protocol. Olfactory dysfunction was assessed using the University of Pennsylvania Smell Identification Test.

Fifty-six patients were included. At six months after coronavirus disease 2019 diagnosis, 64.3 per cent of patients (n = 36) were normosmic, 28.6 per cent (n = 16) had mild to moderate microsmia and 7 per cent (n = 4) had severe microsmia or anosmia. There was a statistically significant association between older age and olfactory dysfunction. Hospital or intensive care unit admission did not lead to worse olfactory outcomes compared to those managed in the out-patient setting.

At six months after coronavirus disease 2019 diagnosis, approximately two-thirds of patients will be normosmic. This study is the first to describe six-month outcomes for post-coronavirus disease 2019 patients in terms of olfactory dysfunction.

This study investigated how the coronavirus disease 2019 pandemic has impacted on presentations to ENT first-on-call services.

All appointments to a rapid access triage clinic from 1 June to 31 August in 2019 and 2020 were reviewed retrospectively and their reasons for consultation classified. A binomial proportion test was used to determine whether the proportions of consultations per presentation differed significantly between years. This analysis was repeated with the number of unique patients per presenting complaint.

The proportions of nine reasons for consultation differed significantly between 2019 and 2020, including an increase in otitis media and nasal trauma presentations, and a decrease in otitis externa and tonsillitis presentations. Reattendances caused some variation in the frequency of certain diagnoses.

Our data suggest a shift in the presentations to first-on-call services, which may be a result of changes in patient behaviour and access to healthcare services.
