Pokročilé využití dat z vyšetření video Head Impulse Test a VEMP

Abstract

The innovative metods video Head Impulse Test (vHIT) and vestibular evoked myogenic potentials (VEMP) belong among the most advanced diagnostic tools, dealing with the state of the balance system. Their combination can be examined for function of the vestibular nerve, since they allow to detect deficits of all balance organs and fibers, that ensure their innervation. In case of cooperation with auditory brainstem response (ABR), used to testing function of the cochlear nerve and the cochlea, it is possible to diagnose the state of the whole vestibulocochlear nerve. The aim of this thesis is design of a software, that allows to connect the results of all three types of inner ear tests to one file, and whose algorithm is capable to objective interpreting the state of the inner ear innervation structure from these available data. For this purpose a system of specialist medical terminology to interpret inner ear diagnoses was created, based on clinically possible combinations of the results of these three tests. Thanks to this, physicians have data that are an essential diagnostic tool for defining a large number of vestibular and auditory disorders or differentiation the peripheral and central character of disease. Software, developed in C# programme, should contribute to further enhancement of medical care in specialized centers for hearing and balance disorders, using the GN Otometrics® instrumentation to testing the above mentioned three methods.
