OBJECTIVES: To determine the typical proportions of diagnoses for patients presenting with dizziness or vertigo based on clinical speciality and to assess the change in proportions of diagnoses over time. DATA SOURCES: Following PRISMA guidelines, systematic searches of PubMed and CINAHL databases and follow-up reference searches were performed for articles published in English up to October 2016. STUDY SELECTION: Analysis of searches yielded 42 studies meeting the criteria of case series of adult patients with dizziness and/or vertigo presenting to general practice, emergency departments or specialist outpatient clinics...

: Transcranial electric stimulation to generate motor evoked potentials in lower limb muscles is the standard technique used to monitor spinal cord efferent pathways during surgical correction for spinal deformities. Monopolar electrical cauterization is also used by default in the thoracic and lumbar area of the spine during this kind of surgery to prevent major blood loss. Owing to the high levels of current used, both techniques are considered contraindicative if the patient has a cochlear implant (CI). Here, we present a CI patient who underwent corrective spinal fusion surgery for a severe kyphoscoliotic spinal deformity on whom both techniques were used without any negative effects on the CI function...

: Many previous attempts have been made to classify or categorize cholesteatomas. Recently, the European Academy of Otology and Neurotology and the Japanese Otological Society proposed a classification system based primarily on extension and complications. The European Academy of Otology and Neurotology/Japanese Otological Society consensus statement makes an effort to standardize reporting of surgical techniques. Internet-based multicenter studies are facilitated by increasing connectivity, but a mutually-agreed framework for reporting is necessary for results to be comparable across sites...

STUDY DESIGN: Retrospective case study. SETTING: Tertiary referral center.

HYPOTHESIS: Biofilm formation on cochlear implant (CI) surfaces differs between bacterial species and can be reduced by the application of S53P4 bioactive glass. BACKGROUND: The formation of bacterial biofilms on medical devices, such as cochlear implants, can lead to chronic infections resulting in the need for implant removal. In this study, various surfaces of three CI implant kits from different manufacturers were examined for bacterial biofilm formation and reduction of a pre-existing biofilm by the application of bioactive glass...

OBJECTIVE: This study aimed to evaluate the changes in the VOR gain after intratympanic gentamicin therapy and to correlate them with the mid-term effects on the control of vertigo, in a population of Menière's disease patients. STUDY DESIGN: The study design was a prospective "Outcomes research." SETTING: Tertiary referral center. PATIENTS: This study included 20 patients with unilateral Menière's disease refractory to medical therapy for at least 1 year, and treated with an on demand intratympanic gentamicin protocol...

HYPOTHESIS: The aim of this study was to present and validate the accuracy of a method to predict the required cochlear implant (CI) electrode array length for a specific angular insertion depth (AID). BACKGROUND: The human cochlea exhibits remarkable interindividual morphological differences. The prediction of the required array length for a specific AID can help to improve the outcome of cochlear implant surgery. METHODS: We estimated the linear insertion depth required for an angular insertion of 540 degrees using computed tomography images of 16 temporal bone specimens (eight Thiel fixed, eight formalin fixed)...

OBJECTIVE: To investigate the effect on final-product performance of a distributed, virtual reality (VR) simulation training program on cadaveric dissection performance and learning curves compared with standard VR simulation training during a temporal bone course. STUDY DESIGN: Educational interventional cohort study. SETTING: The national Danish temporal bone courses of 2016 and 2017. SUBJECTS: Postgraduate year 2 to 5 residents in otorhinolaryngology...

OBJECTIVE: To assess, in patients referred to vestibular rehabilitation (VR) for persistence of disability after acute unilateral vestibulopathy (AUV), whether the video head impulse test (vHIT) can be a useful technique to define the efficacy of the treatment. STUDY DESIGN: Prospective clinical study. SETTING: Tertiary academic referral hospitals. PATIENTS: Thirty patients with residual symptoms after AUV were included...

OBJECTIVE: The objective of this study was to investigate the relationship between endolymphatic hydrops (EH) and hearing level or vestibular symptoms by focusing on EH herniation into the semicircular canal (SCC). STUDY DESIGN: Retrospective study. SETTING: University hospital. METHODS: The study included 1,548 ears of 775 patients who underwent magnetic resonance imaging (MRI) examination in our university hospital to investigate possible EH...

OBJECTIVE: High blood viscosity has been proposed as a mechanism for sudden sensorineural hearing loss (SSNHL); however, the relationship between blood markers of fibrinolysis or coagulation and severity or prognosis of SSNHL is still unclear. The aim of this study is to investigate the relationship between serum fibrinogen and SSNHL. DATA SOURCES: PubMed and Scopus were searched for English language articles using the following keywords: SSNHL, sudden hearing loss, sudden deafness, idiopathic hearing loss or idiopathic sensorineural hearing loss, and fibrinogen...

OBJECTIVE: To investigate factors associated with percutaneous bone anchored hearing implant (BAHI) loss. DATA SOURCES: Africa-Wide, Biosis, Cochrane, Embase, Global Health, LILACs, Medline, Pubmed, and Web of Science electronic databases. STUDY SELECTION: All studies reporting on adult and/or pediatric patients with a BAHI loss were identified. Retrieved articles were screened using predefined inclusion criteria. Eligible studies underwent critical appraisal for directness of evidence and risk of bias...

BACKGROUND: In patients with chronic benign paroxysmal positional vertigo (BPPV), i.e., chronic vestibular multicanalicular canalithiasis (CVMCC), abnormal signals are transmitted from diseased labyrinths via the healthy vestibular nuclei complex to their end organs. The vestibulo-thalamo-cortical reflex as proposed in vestibular migraine is just one of these reflexes. In a group of patients diagnosed with CVMCC otolith repositioning maneuvers specific for each semicircular canal (SCC) ameliorated pain and other symptoms in 90%...

BACKGROUND: We report a unique pattern of focal degeneration of the neuroepithelium of cristae ampullares, thick subepithelial extracellular deposits, and neural degeneration in three humans. OBJECTIVE: To characterize the pattern of vestibular degeneration and measure the thickness of subepithelial deposits in these three cases and controls. METHODS: The subepithelial deposits of vestibular end organs in three subject cases and controls were studied using hematoxylin and eosin, periotic acid-Schiff, Gomori trichrome staining, and immunostaining for antineurofilament, antimyosin VIIa, and anticollagen 4a1...
