Over 30 years ago, the head impulse test (HIT) was measured with search coil recordings and it provided robust evidence for a new test of vestibular function that could detect impairment of a single s...
Recent advances in vestibular testing now permit functional testing of all peripheral vestibular sense organs (all three semicircular canals, utricle, and saccule). This makes it possible to identify ...
The video-Head-Impulse-Test (vHIT) is widely used to evaluate vestibular function. Nevertheless, there is no consensus on the necessary or ideal number of impulses performed for robust VOR gains. Ther...
Until recently, vestibular caloric stimulation was the only objective diagnostic method for isolating the function of the lateral semi-circular canals responsible for maintaining balance. Since 2014, ...
The purpose of this research study is to test whether a Computerized Rotational Head Impulse Test-Vertical (crHIT-vertical) is able to reliably evaluate the vertical semicircular canals in...
The function of the vestibular system among patients with Sudden Sensori Neural Hearing Loss will be evaluted using the video Head Impulse Test
Benign Paroxysmal Positional Vertigo (BPPV) is the most frequent cause of vertigo of peripheral vestibular origin with life time incidence of 2.4%. BPPV is characterized by bouts of acute ...
Cochlear implantation is performed in children with sensorineural hearing loss to restore hearing. Fifty percent of children with sensory neural hearing loss, who are candidates for cochle...
The benign paroxysmal positional vertigo (BPPV) is a type of peripheral vertigo characterized by the accumulation of otoliths debris, which are particles resulted from the condensation of ...
Three long canals (anterior, posterior, and lateral) of the bony labyrinth. They are set at right angles to each other and are situated posterosuperior to the vestibule of the bony labyrinth (VESTIBULAR LABYRINTH). The semicircular canals have five openings into the vestibule with one shared by the anterior and the posterior canals. Within the canals are the SEMICIRCULAR DUCTS.
The three membranous semicircular ducts within the bony semicircular canals. They open into the UTRICLE through five openings. Each duct has at one end a sensory area called the ampullary crest. AMPULLARY HAIR CELLS of the crests sense the movement of ENDOLYMPH resulting from rotation of the head.
A reflex wherein impulses are conveyed from the cupulas of the SEMICIRCULAR CANALS and from the OTOLITHIC MEMBRANE of the SACCULE AND UTRICLE via the VESTIBULAR NUCLEI of the BRAIN STEM and the median longitudinal fasciculus to the OCULOMOTOR NERVE nuclei. It functions to maintain a stable retinal image during head rotation by generating appropriate compensatory EYE MOVEMENTS.
Identification of SACCADES during a rapid head rotation to assess VESTIBULOOCULAR REFLEX.
Pathological processes of the inner ear (LABYRINTH) which contains the essential apparatus of hearing (COCHLEA) and balance (SEMICIRCULAR CANALS).
