BACKGROUND: Surgical management of Ménière's disease (MD) is recommended in case of medical and intratympanic treatment failures. Translabyrinthine vestibular nerve section has been considered the gold standard for denervation procedures in order to control vertigo attacks, although at the cost of sacrificing residual hearing. To the best of our knowledge, no work has been published with regard to a group of patients submitted to translabyrinthine vestibular neurectomy and simultaneous cochlear implant for MD...

INTRODUCTION: Ménière's disease (MD) is an inner ear disorder characterized by episodic vertigo, tinnitus, ear fullness, and fluctuating hearing. Its diagnosis can be especially difficult in cases where vestibular symptoms are present in isolation (vestibular MD). The definitive diagnosis is made histologically and can only be performed post-mortem, after analysis of the temporal bone. Endolymphatic hydrops is a histopathological finding of the disease and occurs more often in the cochlea and saccule, followed by the utricle and semicircular canals...

INTRODUCTION: The vestibular evoked myogenic potential is a potential of mean latency that measures the muscle response to auditory stimulation. This potential can be generated from the contraction of the sternocleidomastoid muscle and also from the contraction of extraocular muscles in response to high-intensity sounds. This study presents a combined or simultaneous technique of cervical and ocular vestibular evoked myogenic potential in individuals with changes in the vestibular system, for use in otoneurologic diagnosis...

Vestibular neuritis (VN) is one of the most common causes of vertigo and is characterised by a sudden unilateral vestibular failure (UVF). Many neuroimaging studies in the last 10 years have focused on brain changes related to sudden vestibular deafferentation as in VN. However, most of these studies, also due to different possibilities across diverse centres, were based on different times of first acquisition from the onset of VN symptoms, neuroimaging techniques, statistical analysis and correlation with otoneurological and psychological findings...

OHNS is a medical specialty born at the end of the 19th century. It is the congruence of otology and laryngology, rapidly associated with rhinology. It went through three chronological steps: construction in the second part of the 19th century, consolidation in the first part of 20th century and extension in the second part of the 20th and beginning of the 21st century. Scientifically, OHNS was set out into five partially layered phases: bedside teaching, introduction of anatomopathology, invention of clinic experiments, expansion of surgery, and use of highly technological advances...

INTRODUCTION AND OBJECTIVES: Extra-tympanic electrocochleography is an electrophysiological register obtained after stimulating the cochlea with an audible stimulus. This stimulus is applied using an earphone over the external auditory canal, while the electrical activity is registered by surface electrodes. There are few studies that analyse normal electrocochleography in our environment. Thus, the main objective of our study was to regularize the values obtained with electrocochleography in ears without any otoneurological diseases...

According to international statistics, the first examination of 25% of patients with vertigo is carried out in Emergency Departments. The most important task of the examining physician is to diagnose life threatening pathologic processes. One of the most difficult otoneurological diagnostic challange in Emergency Departments is to differentiate between dangerous posterior scale stroke presenting with isolated vertigo and the benign vestibular neuritis.These two disorders can be safely differentiated using fast, non-invasive, evidence based bedside tests which have been introduced in the past few years...

PURPOSE OF REVIEW: The review presents a selection of recent studies in the field of vestibular neuroscience, including how vestibular stimulation modulates space and body perception. RECENT FINDINGS: Recent neuroimaging studies identified the operculo-insular/retroinsular cortex as the core vestibular cortex and showed how it is reorganized after vestibular dysfunctions. Subliminal galvanic vestibular stimulation (GVS) induces long-term reduction of hemispatial neglect and improves vertical perception in stroke patients, but the underlying mechanisms remain to be identified...

Melkersson-Rosenthal Syndrome (MRS) is a rare otoneurologic condition, which is poorly understood and often underdiagnosed. Etiology and incidence are unclear, although infectious, inflammatory, and genetic causes have been implicated. Recurrent facial nerve palsy, facial swelling, and fissured tongue are the symptoms and signs of this condition. However, this triad is not typical in all patients as patients may present with one or more of the symptoms, which makes management of this condition difficult. Steroids may prove to be useful especially in patients who have facial nerve palsy...

The assessment of acute vertigo in childhood is often challenging, but fortunately a central cause is rarely identified. We present the case of a 7-year-old boy who developed, after a mild head trauma, a rotary vertigo associated with nausea and vomiting. A posttraumatic peripheral vestibular dysfunction was first suspected but not confirmed by an otoneurological evaluation. When subtle neurological signs were elicited, a brain magnetic resonance imaging was promptly requested. This showed a small infarct on the lateral posterior left part of the medulla oblongata of the brainstem, typical of Wallenberg syndrome...

The up-to-date bedside otoneurological examination of the dizzy patients consists of a number of tests and procedures of paramount importance for the localization and diagnostics of the causes underlying dizziness. Recent progress in neurootology made it possible to improve the quality of physical examination and diagnostics; thereby, it promoted the choice of the most adequate treatment. The authors maintain that the modern otoneurological examination must include the following mandatory stages: the measurement of the head tilt and the eye position; the assessment of the presence and the character of nystagmus, oculomotor reactions (saccades, smooth pursuit movements, optokinetic reflex), and vestibular-ocular reflex; the performance of provocative tests and positioning maneuvers; posture and balance control estimation; evaluation of the hearing function...
