Analysis of wideband tympanometry in Ménière's disease.

Introduction: Endolymphatic hydrops is the pathophysiological substrate of Ménière's disease. The changes in the inner ear, transmitted to the middle ear through changes in the ossicular chain mobility, can be quantified by wideband tympanometry, through the measurement of the acoustic absorbance at multiple frequencies, represented by the sound energy absorbed by the middle ear, even at its early stages. Studying the behavior of the middle ear through the absorbance in patients with endolymphatic hydrops under ambient pressure and under peak pressure can be useful for detecting Ménière's disease.

Neurotology: definitions and evidence-based therapies - Results of the I Brazilian Forum of Neurotology.

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.

Facial nerve hemangioma in the middle ear.

Facial nerve hemangioma is a rare and benign vascular tumor, and accounts for 0.7% of intratemporal tumors. We report the second case described in the literature of a facial nerve hemangioma in its tympanic segment.

Tinnitus and sound intolerance: evidence and experience of a Brazilian group.

Introduction: Tinnitus and sound intolerance are frequent and subjective complaints that may have an impact on a patient's quality of life.

Objective: To present a review of the salient points including concepts, pathophysiology, diagnosis and approach of the patient with tinnitus and sensitivity to sounds.

Methods: Literature review with bibliographic survey in LILACS, SciELO, Pubmed and MEDLINE database.

Quality of life in elderly with dizziness.

Unlabelled: Dizziness is frequent in elderly people.

Aims: To evaluate the Quality of Life (QoL) in elderly subjects with dizziness, relate it with gender and age.

Material And Method: A prospective study comprising 120 elderly patients with dizziness evaluated with Brazilian versions of the Whoqol-bref and the dizziness handicap inventory (DHI).

Varicella zoster virus in Bell's palsy: a prospective study.

Unlabelled: Although Bell's palsy is the major cause of acute peripheral facial palsy, its pathogenesis remains unknown. Reactivation of the varicella zoster virus has been implicated as one of the main causes of Bell's palsy, however, studies which investigate the varicella zoster virus reactivation in Bell's palsy patients are mostly Japanese and, therefore, personal and geographic characteristics are quite different from our population.

Aims: To determine varicella zoster virus frequency in saliva samples from patients with Bell's palsy, using PCR.

The interference of voice change on structural vocal cords lesions.

Unlabelled: A longitudinal cohort study Introduction: Voice change may be defined as a group of changes in voice pattern that take place between childhood and puberty. During this period some vocal cord lesions (specifically cysts and nodules) may undergo transformation.

Aim: To evaluate changes in vocal cord structural lesions following voice changes.
