Vestibular disorders

چکیده
The membranous labyrinth of the inner ear develops from the otic capsule between the fourth and twelfth weeks of intrauterine life. The cartilage around the capsule differentiates into the osseous labyrinth at 6-7 weeks' gestation and, at that time, is separated from the membranous portion by the perilymphatic space (Dayal, Farkushidy and Kokshanian, 1973). As the vestibular system is older phylogenetically, each stage in the development of this system is in advance of that of the auditory system, and is therefore less vulnerable to environmental insult.

Factors Associated with Vestibular Disorders in Patients with Sensorineural Hearing Loss Due to Acute Acoustic Trauma: A brief report
Background & Aim: Acute acoustic trauma is an important cause of sensorineural hearing loss (SNHL). Determination of the frequency and contributing factors for vestibular disorders is important, therefore, the current study was performed to assess these factors in patients referred to the ears, nose, and throat (ENT) clinic of one of the hospitals in Tehran, Iran, during the years 2017 to 2019....

The vestibular system is important for the development of normal movement reactions, motion tolerance, and motor control for postural alignment, balance, and vision. A vestibular system that is damaged by disease or injury in childhood can have a major impact on a child’s development. In addition, the emergence of vestibular lesions may also lead to cognitive deficits,...

Background and purpose: Vestibular Schwannoma (VS) is a lesion in peripheral vestibular system that leads to reduction of Vestibulo Ocular Reflex (VOR) gain and incidence of corrective saccades. Researches showed that the result of Video Head Impulse Test (VHIT) is positive in peripheral vestibular system disorders and negative in central vestibular system disorders. The aim of this study was t...

Objectives: Rehabilitation strategies play a pivotal role in reliving the inappropriate behaviors and improving children's performance during school. Concentration and visual and auditory comprehension in children are crucial to effective learning and have drawn interest from researchers and clinicians. Vestibular function deficits usually cause high level of alertness and vigilance, and proble...
متن کاملVestibular Evoked Myogenic Potential Produced by Bone-Conducted Stimuli: A Study on its Basics and Clinical Applications in Patients With Conductive and Sensorineural Hearing Loss and a Group With Vestibular Schawannoma
Introduction: Vestibular evoked myogenic potential (VEMP) has recently been broadly studied in vestibular disorders. As it is evoked by loud sound stimulation, even mild conductive hearing loss may affect VEMP results. Bone-conducted (BC) stimulus is an alternative stimulation for evoking this response. This study aims to assess the characteristics of BC-VEMP in different groups of patients. ...
