The wait and scan policy is being increasingly used as the first measure after the diagnosis of a vestibular schwannoma (VS) using magnetic resonance imaging (MRI). As part of the European Academy of Otology and Neuro-Otology (EAONO) position statement on VS, the frequency of imaging has been studied in the literature. Among 163 studies, 29 fulfilled the inclusion criteria and were scored using the Grading of Recommendations, Assessment, Development, and Evaluation system. Because tumor growth rate during the first 5 years of follow-up is predictive of further growth during the upcoming years, a protocol for wait and scan is useful for centers dealing with this condition...

Vestibular dysfunction is associated with visual short-term memory impairment; however, it remains unclear if this impairment arises as a direct result of the vestibular dysfunction or is a consequence of comorbid changes in mood, affect, fatigue, and/or sleep. To this end, we assessed the concurrence and interdependence of these comorbidities in 101 individuals recruited from a tertiary balance clinic with a neuro-otological diagnosis. Over fifty per cent of the sample showed reduced visuospatial short-term memory, 60% and 37% exceeded cut-off on the Beck Anxiety and Depression Inventories, respectively, 70% exceeded cut-off on the Fatigue Severity Scale, 44% reported daytime sleepiness on the Epworth Sleepiness Scale, and 78% scored above cut-off on the Pittsburgh Sleep Quality Index...

Identifying the occurrence of stroke in patients with isolated vertigo is difficult for general practitioners (GPs) as well as for physicians working in the Emergency Department. Three patients with acute vestibular syndrome are presented in this clinical lesson. The importance of an adequate neuro-otological examination is emphasised. However, many GPs lack knowledge of the nystagmus and the head impulse test. Alternative strategies for GPs are discussed.

Perilymphatic fistula is defined as an abnormal communication between the perilymph-filled space and the middle ear, or cranial spaces. The manifestations include a broad spectrum of neuro-otological symptoms such as hearing loss, vertigo/dizziness, disequilibrium, aural fullness, tinnitus, and cognitive dysfunction. By sealing the fistula, perilymphatic fistula is a surgically correctable disease. Also, appropriate recognition and treatment of perilymphatic fistula can improve a patient's condition and hence the quality of life...

REVIEW
Stoyan Popkirov, Jeffrey P Staab, Jon Stone
Persistent postural-perceptual dizziness (PPPD) is a newly defined diagnostic syndrome that unifies key features of chronic subjective dizziness, phobic postural vertigo and related disorders. It describes a common chronic dysfunction of the vestibular system and brain that produces persistent dizziness, non-spinning vertigo and/or unsteadiness. The disorder constitutes a long-term maladaptation to a neuro-otological, medical or psychological event that triggered vestibular symptoms, and is usefully considered within the spectrum of other functional neurological disorders...

The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope...

Metastasis to the cerebellopontine angle (CPA) or internal auditory meatus (IAM) is rare.We report a rare case of a 69-year-old woman with metastatic lung adenocarcinoma, who presented with 2 weeks history of left-sided hearing loss and progressively worsening vertigo. Examination revealed a left-sided facial nerve palsy while pure tone audiometry (PTA) showed a new left-sided deafness. MRI showed a new enhancing soft tissue lesion in the left IAM, highly suspicious of new metastases from her progressive lung cancer, which contributed to her neuro-otological symptoms...
