Patients presenting to the emergency department with acute vertigo pose a diagnostic challenge. While ‘benign’ peripheral vestibulopathy is the most common cause, the possibility of a posterior circulation stroke is paradoxically the most feared and missed diagnosis in the emergency department.

This review will attempt to cover the significant advances in the ability to diagnose acute vertigo that have occurred in the last two decades. The review discusses the role of neurological examinations, imaging and specific oculomotor examinations. The review then discusses the relative attributes of the Head Impulse-Nystagmus-Test of Skew plus hearing (‘HINTS+’) examination, the timing, triggers and targeted bedside eye examinations (‘TiTrATE’), the associated symptoms, timing and triggers, examination signs and testing (‘ATTEST’) algorithm, and the spontaneous nystagmus, direction, head impulse testing and standing (‘STANDING’) algorithm. The most recent technological advancements in video-oculography guided care are discussed, as well as other potential advances for clinicians to look out for.

Balance dysfunction and vestibular conditions are major problems requiring significant resources. There is significant national and international variation in management pathways for such patients.

This paper outlines a collaborative project run by the ENT department and two vestibular rehabilitation trained physiotherapists to establish a clinic to manage patients referred to ENT with vestibular and/or balance complaints. As part of a six-month pilot, two physiotherapy-led balance clinics were provided per week.

A total of 159 new patients were seen, with only 15 needing ENT consultant input. This led to the successful creation of substantive posts; the clinic has seen 698 patients in its first two years.

Patient outcomes and experience have been positive, and accompanied by reduced waiting and in-service times. The authors discuss some of the pitfalls, challenges and opportunities of developing this type of clinic.

This pilot study aimed to evaluate a training programme for primary care physiotherapists focused on the assessment and management of benign paroxysmal positional vertigo.

A six-month training programme and toolkit utilising the revised Standards for Quality Improvement Reporting Excellence (‘SQUIRE 2.0’) guidelines was developed to facilitate the learning of new knowledge and skills in the assessment and management of benign paroxysmal positional vertigo following Gagne's model of instructional design. A pre- and post-training knowledge and confidence questionnaire evaluated the impact of the training programme.

Eleven participants started the training programme and five completed it. On average, knowledge increased by 54 per cent (range, 41–95 per cent) and confidence increased by 45 per cent (range, 31–76 per cent). A 73 per cent improvement in practical skills acquisition was demonstrated after the initial training session.

A structured approach to learning demonstrates improvements in knowledge, skills and confidence of physiotherapists in the evidence-based management of benign paroxysmal positional vertigo.

To examine the newly established role of a primary contact physiotherapist in an ENT clinic, in an Australian cohort and context, over two phases of development.

A retrospective cohort study was conducted with data collected from a medical record audit. Over the study duration, the primary contact physiotherapist completed initial appointments with patients; follow-up appointments were subsequently conducted by medical staff.

There was a 46 per cent reduction in patients with suggested vestibulopathy requiring an ENT medical review. This reduction could hypothetically increase to 71 per cent with follow-up primary contact physiotherapist appointments. Improvements in the service delivery model and a primary contact physiotherapist arranging diagnostic assessments could improve waitlist times and facilitate better utilisation of medical staff time.

The primary contact physiotherapist can help in the management of patients with suspected vestibulopathy on an ENT waitlist. This is achieved through: a reduction of patients requiring ENT review, improvements to waitlist time and improved utilisation of medical specialists’ time.

Persistent postural-perceptual dizziness classifies patients with chronic dizziness, often triggered by an acute episode of vestibular dysfunction or threat to balance. Unsteadiness and spatial disorientation vary in intensity but persist for over three months, exacerbated by complex visual environments.

Literature suggests diagnosis relies on a clinical history of persistent subjective dizziness and normal vestibular and neurological examination findings. Behavioural diagnostic biomarkers have been proposed, to facilitate diagnosis.

Research has focused on understanding the neural mechanisms that underpin this perceptual disorder, with imaging data supporting altered connectivity between neural brain networks that process vision, motion and emotion. Behavioural research identified the perceptual and motor responses to a heightened perception of imbalance.

Management utilises head and body motion detection, and downregulation of visual motion excitability, reducing postural hypervigilance and anxiety. Combinations of physical and cognitive therapies, with antidepressant medications, help if the condition is associated with mood disorder.

Differential diagnosis of acute vertigo syndrome is challenging given the similarities between clinical presentations of posterior circulation stroke and peripheral vestibular dysfunction. The Head Impulse, Nystagmus, Test of Skew (‘HINTS’) assessment is a clinical bedside test used to aid diagnosis.

Comprehensive training on use of the Head Impulse, Nystagmus, Test of Skew assessment was provided to one stroke consultant, and the effectiveness of the test in that setting was assessed. Further education was completed with more members of the stroke and emergency department multi-disciplinary team. Quality improvement measures including magnetic resonance imaging use and bed utilisation were explored.

Following training of one stroke consultant, the Head Impulse, Nystagmus, Test of Skew assessment was found to be a feasible, accurate bedside test within this acute stroke service. Further training for the multi-disciplinary team was completed, but outcome measures were not explored because of the coronavirus disease 2019 pandemic and maternity leave.

There is a role for trained members of the multi-disciplinary team to successfully use the Head Impulse, Nystagmus, Test of Skew assessment in hyperacute stroke settings, to aid diagnosis in acute vertigo syndrome.

Driving capacity is affected by vestibular disorders and the medications used to treat them. Driving is not considered during medical consultations, with 92 per cent of patients attending a centre for dizziness not discussing it with the doctor.

To investigate if medical record prompts facilitate dizziness and driving conversations in ENT balance clinics.

A questionnaire was designed to reflect the current standards of practice and advice given regarding driving and dizziness during balance clinic consultations.

Medical record prompts facilitated the improved frequency and recording of shared decision-making conversations about driving and dizziness in 98 per cent of consultations.

This study highlights the benefits of medical record prompts for documented and accurate shared decision-making conversations surrounding dizziness, vertigo, vestibular conditions and driving. This potentially improves safety for all road users, and protects the patient and clinician in the event of road traffic accidents and medico-legal investigations.

In decision making regarding the management of vestibular schwannomas, alongside clinical outcomes, an understanding of patient reported health-related quality of life measures is key. Therefore, the aim of this research is to compare health-related quality of life in vestibular schwannoma patients treated with active observation, stereotactic radiotherapy and microsurgical excision.

A cross-sectional study of patients diagnosed with unilateral sporadic vestibular schwannomas between 1995 and 2015 at a specialist tertiary centre was conducted. Patients completed the Penn Acoustic Neuroma Quality of Life questionnaire and handicap inventories for dizziness, hearing and tinnitus.

Of 234 patients, 136 responded (58.1 per cent). Management modality was: 86 observation, 23 stereotactic radiotherapy and 25 microsurgery. Females reported significantly worse dizziness; males reported significantly worse physical disability. Patients less than 65 years old reported significantly worse tinnitus and pain scores. Overall, quality of life was higher in the observation group.

Conservative management, where appropriate, is favourable with higher quality-of-life outcomes in this cohort. This must be weighed against the risks of a growing tumour.

There have been many studies linking falls and benign paroxysmal positional vertigo. This article collates those studies, and demonstrates how a community falls service fast-tracked patients with benign paroxysmal positional vertigo by implementing validated screening tools and recognised guidance.

This study aimed to explore whether routine screening of referrals to a community falls service can identify those with benign paroxysmal positional vertigo, for fast-tracked management.

Patients referred to a community falls service were screened for possible benign paroxysmal positional vertigo using the Dizziness Handicap Inventory, and triaged to a physiotherapy-led falls and benign paroxysmal positional vertigo assessment service.

Twenty-five per cent of patients were fast-tracked to a falls and benign paroxysmal positional vertigo assessment service for management. The community falls service waiting list reduced by 25 per cent.

The data support incorporating assessment and treatment of benign paroxysmal positional vertigo into routine practice within all falls services.

Vestibular migraine is a newly recognised and debilitating condition. This article aims to provide an overview of what is known of vestibular migraine, delineating its diagnostic criteria and presenting some initial management strategies to aid ENT professionals in delivering optimal care when patients first present to the otolaryngology clinic.

Although traditionally underdiagnosed, there are now clearly defined diagnostic criteria to aid accurate diagnosis of vestibular migraine.

A detailed history and clinical examination are the cornerstone of the diagnostic process, but supportive evidence is required from appropriate audio-vestibular tests and imaging.

This is a unique condition that commonly initially presents to ENT. This article provides a summary of diagnostic and management strategies to facilitate early diagnosis and first-line treatment that can be employed in general ENT settings, which may be particularly useful given the limited availability of specialist audio-vestibular medicine and neuro-otology services.

There is a high prevalence of dizziness, vertigo and balance symptoms in the general population. Symptoms can be generated by many inner-ear vestibular disorders and there are several diagnostic tests available that can help identify the site of the vestibular lesion. There is little consensus on what diagnostic tests are appropriate, with diagnostics either not completed or minimally performed, leading to missed diagnosis, unsatisfactory results for patients and costs to healthcare systems.

This study explored the literature for different neuro-vestibular diagnostic tests not currently considered in the traditional standard vestibular test battery, and examined how they fit effectively into a patient care pathway to help quickly and succinctly identify vestibular function.

A vestibular patient care pathway is presented for acute and subacute presentation of vestibular disorders.

An accurate diagnosis following a rigorous anamnesis and vestibular testing is paramount for successful management and favourable outcomes.

To examine the correlation of video head impulse test, functional head impulse test and Dizziness Handicap Inventory results in patients with chronic unilateral vestibular loss, and to compare the results with healthy controls.

Forty-eight patients diagnosed with chronic unilateral vestibular loss and 35 healthy individuals, aged 18–65 years, were included. The video head impulse test, functional head impulse test and Dizziness Handicap Inventory were administered.

A significant positive correlation was found between functional head impulse test and video head impulse test results for the study group in all semicircular canals (p < 0.05). There was no significant correlation between Dizziness Handicap Inventory, functional head impulse test and video head impulse test results (p > 0.05). The functional head impulse test and video head impulse test results of the control group were significantly higher than those of the study group in all semicircular canals planes (p < 0.05).

In chronic unilateral vestibular loss patients, with high head accelerations, the functional head impulse test indicates deterioration in vestibulo-ocular reflex functionality. It would be beneficial to include the video head impulse test and functional head impulse test in clinical practice as complementary tests in vestibulo-ocular reflex evaluation.

This study aimed to compare the pre- and post-operative vestibular and equilibrium functions of patients with cholesteatoma-induced labyrinthine fistulas who underwent different management methods.

Data from 49 patients with cholesteatoma-induced labyrinthine fistulas who underwent one of three surgical procedures were retrospectively analysed. The three management options were fistula repair, obliteration and canal occlusion.

Patients underwent fistula repair (n = 8), canal occlusion (n = 18) or obliteration procedures (n = 23). Patients in the fistula repair and canal occlusion groups suffered from post-operative vertigo and imbalance, which persisted for longer than in those in the obliteration group. Despite receiving different management strategies, all patients achieved complete recovery of equilibrium functions through persistent efforts in rehabilitation exercises.

Complete removal of the cholesteatoma matrix overlying the fistula is reliable for preventing iatrogenic hearing deterioration due to unremitting labyrinthitis. Thus, among the three fistula treatments, obliteration is the optimal method for preserving post-operative vestibular functions.

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.

Idiopathic sudden sensorineural hearing loss may be accompanied by dizziness without true vertigo. This study used the video head impulse test to evaluate vestibular function in idiopathic sudden sensorineural hearing loss patients who described experiencing dizziness and not true vertigo.

A prospective study was conducted of 30 consecutive patients diagnosed with idiopathic sudden sensorineural hearing loss with dizziness without true vertigo. A comparison of the video head impulse test results of the patients who complained of dizziness (symptomatic group) with a group of patients with idiopathic sudden sensorineural hearing loss and no dizziness (asymptomatic) was performed.

Nine patients (30 per cent) were symptomatic. Two of those patients had abnormal video head impulse test findings. Seven patients in the asymptomatic group (7 out of 21, 33 per cent) presented with abnormal video head impulse test results. No significant difference in vestibular function between the two groups was detected by the video head impulse test.

The site of insult in patients with idiopathic sudden sensorineural hearing loss without true vertigo is usually limited to the cochlea or the cochlear nerve.

This article presents the case of an adolescent with asymptomatic coronavirus disease 2019 infection who had vestibular neuronitis symptoms.

The new coronavirus disease 2019 demonstrates neurotropic properties, apart from airway symptoms. Early in the pandemic, coronavirus disease 2019 infection had been associated with olfactory disturbances. Accumulative evidence supports that both the infection with coronavirus disease 2019 and the vaccination against the virus may induce a condition of vestibular hypofunction, known as vestibular neuronitis. Coronavirus disease 2019 may directly affect the vestibular organs and ganglia, or indirectly damage them via immune-mediated mechanisms. In most cases, complete recovery is achieved with the typical therapeutic approaches for vestibular neuronitis, consisting of supportive measures and corticosteroids.

Physicians may expect an increased incidence of vestibular neuronitis during the coronavirus disease 2019 pandemic. Conversely, coronavirus disease 2019 infection should be considered in patients with sudden vestibular symptoms.

Vestibular migraine is in the process of recognition as an individual clinical entity. At present, no guidelines exist for its management. This study aimed to conduct a systematic review and meta-analysis to determine the effectiveness of available prophylactic medication.

A literature search was performed using PubMed, Ovid and Embase databases. Qualitative and quantitative analysis were performed as well as risk of bias analysis. Meta-analysis for the mean differences for pre- and post-treatment impact based on Dizziness Handicap Inventory and Vertigo Symptom Scale were performed. Proportionate transformation meta-analysis for the successful event rate based on complete symptoms control was explored.

Thirteen publications were identified: 3 were randomised, controlled trials and 10 were non-randomised, controlled trials. Propranolol and venlafaxine improved the Vertigo Symptom Scale score by −13.31 points and −4.16 points, respectively, and the Dizziness Handicap Inventory score by −32.24 and −21.24, respectively. Only propranolol achieved statistically significant impact with 60 per cent of patients achieving complete symptom control.

Propranolol should be offered as the first-line treatment for vestibular migraine followed by venlafaxine. Amitriptyline, flunarizine and cinnarizine showed a trend for symptom improvement, but this was not statistically significant.

Bilateral Ménière's disease is classified according to the time of appearance of symptoms in each ear into synchronous and metachronous types. A descriptive longitudinal study, involving 59 bilateral Ménière's disease patients, was carried out to assess the two forms of bilateral Ménière's disease.

Data on symptomatic chronology in each ear, auditory evolution and evolution of vertiginous crisis, among other aspects, were obtained, analysed and compared. Possible risk factors for Ménière's disease becoming bilateral were analysed after conducting nested case–control studies in a cohort.

The metachronous form was seen in 76.3 per cent of cases, and the time it took for the disease to become bilateral took a median time of seven years. The symptomatic triad was the most frequent symptomatic debut for the first ear in both forms. Synchronous debut presented a greater average hearing loss. Suffering from migraine and a symptomatic onset with a greater number of symptoms appear to be possible predictors of conversion to bilateral Ménière's disease.

Bilateral Ménière's disease temporal models presented differences. The study of them helps to better understand, prevent and predict the behaviour of these patients.
