Purpose: To determine the internal consistency and reliability of the "Questionário de Impacto Emocional da Vertigem (CIEV)" and to validate the instrument with respect to the Dizziness Handicap Inventory (DHI) in a sample of individuals with balance disorders.

Methods: 38 subjects participated in the study, males and females, aged from 23 to 85 years, who presented dizziness, vertigo, and/or falls complaints and attended to the Vestibular Disorders clinic at the University Hospital. Individuals with hearing complaints and/or tinnitus unrelated to dizziness, previous psychiatric comorbidities, and/or cognitive impairments were excluded.

Objective: To analyze, by means of a systematic review and meta-analysis, the proportion of patients with Meniere's disease who have altered caloric test and vHIT, as well as to determine the prevalence of altered caloric test and normal vHIT dissociation in the diagnosis of Meniere's disease.

Methods: The literature search had no restriction regarding the period of publication on the following indexed data platforms: PubMed, PubMed PMC, BVS-Bireme, Web of Science, Embase and Cochrane Library. Articles that evaluated patients with Meniere's disease who underwent caloric test and vHIT were included.

Introduction: Vestibular recruitment is a sign of hyperexcitability of central vestibular neurons and may be characteristic of peripheral vestibular damage.

Objective: To define the post-caloric recruitment index and its ability to predict the stage of vestibular compensation and peripheral lesion.

Methods: First of all, we demonstrated that larger values in the cold post-caloric stimulation compared to warm stimulation were equivalent to vestibular recruitment observed during the sinusoidal harmonic acceleration test.

Introduction: Caloric testing is the most frequently used test to assess peripheral vestibular function since the beginning of the 20th century. However, the video head impulse test, vHIT, has gained prominence in the field of neurotology, as it is a faster examination, easier to perform and less uncomfortable for the patient.

Objective: To compare, through systematic review and meta-analysis, the proportion of altered cases between vHIT tests and caloric testing in patients with chronic dizziness, in addition to assessing the sensitivity and specificity of vHIT, with caloric testing as the gold standard.

Purpose: To propose a normalization model of a posturography platform in adults without changes in body balance, through descriptive analysis by age group and sex.

Methods: Cross-sectional observational study. Adults, with no changes in body balance and no vestibular complaints were submitted to 6 sensory conditions on the Horus® posturography platform.

Introduction: Neurotology is a rapidly expanding field of knowledge. The study of the vestibular system has advanced so much that even basic definitions, such as the meaning of vestibular symptoms, have only recently been standardized.

Objective: To present a review of the main subjects of neurotology, including concepts, diagnosis and treatment of Neurotology, defining current scientific evidence to facilitate decision-making and to point out the most evidence-lacking areas to stimulate further new research.

Objectives: Currently, cochlear implant procedures are becoming increasingly broad and have greatly expanded. Bilateral cochlear implants and cochlear implants are more frequently applied in children. Our hypothesis is that the video head impulse test may be more sensitive than the caloric test in detecting abnormal vestibular function before cochlear implant surgery.

Background: Cochlear implantation (CI) is the gold standard therapy for profound or severe sensorineural hearing loss. It is a safe surgical procedure but, because of the proximity of the cochlea and vestibule, postoperative vestibular disorder may occur. Our hypothesis is that the video head impulse test (vHIT) may be a good tool to achieve a topographic diagnosis of dizziness in the early postoperative period after CI.

Objective:: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction.

Methods:: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical courses completed the caloric test and video head impulse test.

Results:: Significantly more caloric test results than video head impulse test results were abnormal.

Introduction: Global sugar consumption has increased in the past 50 years; its abusive intake is responsible for peripheral insulin resistance, which causes the metabolic syndrome - obesity, diabetes mellitus, hypertension, and coronary heart disease.

Objective: To evaluate the effect of a fractionated diet without glucose as treatment for labyrinthine disorders associated with glucose-insulin index.

Methods: The study design was a prospective randomized controlled trial.

Tinnitus is characterized by an auditory perception of sound, with no stimuli from the external environment. Tinnitus is an increasingly significant complaint, affecting 10-17% of the world population. As a symptom, it should always be considered with pathology in the auditory system.

Article Synopsis
  • - Hyperacusis, an increased sensitivity to sound that can precede tinnitus, affects some patients who experience tinnitus symptoms.
  • - A study evaluated 309 patients with tinnitus to explore how common hyperacusis is and its impact on tinnitus annoyance, using clinical evaluations and questionnaires.
  • - Findings showed that 18.4% of patients had hyperacusis, but annoyance levels from tinnitus were similar for those with or without hyperacusis, indicating no correlation between the two.

Introduction: The perception of tinnitus varies among individuals. The limitations caused by tinnitus are related to psychological factors, mood changes and psychiatric conditions, while other factors related to discomfort caused by tinnitus are being studied. Hearing loss is an important factor for the onset of tinnitus.

Study Design: Cross-sectional study.

Objective: To evaluate the relationship between the occurrence of falls and muscle strength, flexibility, and balance in postmenopausal women with and without osteoporosis.

Background: Osteoporosis and falls are common problems encountered in the elderly.

Benign paroxysmal positional vertigo is a common disorder in Neurotology. This vestibular syndrome is characterized by transient attacks of vertigo, caused by change in head position, and associated with paroxysmal characteristic nystagmus. The symptoms result from movement of the free floating otoconia particles in the endolymph or their attachment to the cupulae of the semicircular canal.

The study of oculomotricity is performed by evaluating three systems: saccadic ocular movements (SOMs), optokinetic nystagmus (OKN), and smooth pursuit eye movements (SPEMs). Our aim was to study oculomotricity in patients with a complaint of only tinnitus and to compare it with the value of our control group. We studied the SOMs, OKN, and SPEMs in 25 patients complaining only about tinnitus and in 35 normal adults and compared the results.

Article Synopsis
  • Recent studies indicate that cochlear implants can suppress tinnitus symptoms, often even in ears that did not receive the implant.
  • In a study of 29 adults with profound hearing loss, 71% showed improvement in tinnitus perception after their cochlear implants were activated.
  • Among patients with bilateral tinnitus, 86% experienced complete or significant relief in both ears following the procedure.
