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.

Tissue response evaluation of the mucosa of the tympanic cavity of guinea pigs, when receiving biodegradable implant.

Purpose: To evaluate the tissue response of the mucosa of the tympanic cavity of guinea pigs, when receiving biodegradable implant.

Methods: A total of 20 male guinea pigs were divided into 2 groups. After paracentesis in both ears, a biodegradable polymer of poly lactic-co-glycolic acid was implanted in only one middle ear.

Clinical and functional aspects of body balance in elderly subjects with benign paroxysmal positional vertigo.

Unlabelled: Benign paroxysmal positional vertigo (BPPV) may compromise the balance of elderly subjects.

Objective: To observe the effects of the Epley maneuver in elderly subjects with BPPV and assess clinical and functional aspects of body balance.

Method: This is a prospective clinical study.

Vestibular evoked myogenic potentials and digital vectoelectro-nystagmography's study in patients with benign paroxysmal positional vertigo.

Introduction:  Benign Paroxysmal Positional Vertigo (BPPV) is a very common vestibular disorder characterized by brief but intense attacks of rotatory vertigo triggered by simple rapid movement of the head. The integrity of the vestibular pathways can be assessed using tests such as digital vectoelectronystagmography (VENG) and vestibular evoked myogenic potentials (VEMP).

Aim:  This study aimed to determine the VEMP findings with respect to latency, amplitude, and waveform peak to peak and the results of the oculomotor and vestibular components of VENG in patients with BPPV.

Vestibular evoked myogenic potential in unilateral vestibular hypofunction.

Conclusion: The patients with unilateral chronic vestibular hypofunction detected by caloric test demonstrated at least some sort of altered vestibular evoked myogenic potential (VEMP) in 63.63% of the cases. The VEMP altered side was the same as the unilateral vestibular hypofunction side in 54.

The number of procedures required to eliminate positioning nystagmus in benign paroxysmal positional vertigo.

Aim: To evaluate the number of weekly canalith repositioning procedures needed to eliminate positioning nystagmus in patients with benign paroxysmal positional vertigo and to verify influences of canalithiasis or cupulolithiasis and/or semicircular canal involvement.

Study Design: clinical prospective with transversal cohort.

Material And Method: Sixty patients with benign paroxysmal positional vertigo were consecutively selected according to each combination of canalithiasis or cupulolithiasis with semicircular canal involvement.
