Peculiarities of differential diagnostics of perilymphatic fistulas of the labyrinth windows of non-inflammatory genesis
THE PURPOSE OF THE STUDY: To determine the value of the results of various audiological and vestibulometric studies for the differential diagnosis of non-inflammatory perilymphatic fistulas of the labyrinth windows (PFOLW).
MATERIAL AND METHODS: The retrospective and prospective analysis of the informative value of the results of audiological and vestibulometric studies was carried out in 124 people with different combinations of cochleovestibular complaints, who had different pathology of the inner and middle ear, with different terms of the disease - from several days to 30 years. To assess the informativeness of the applied testing, the following operational characteristics were determined: general sensitivity (Se), specificity (Sp) and the prognostic value of a positive result (PPV=positive predictive value). A pair-by-pair comparison of the prognostic value of a positive result of vestibulometric and audiometric tests was performed using the Pearson criterion χ2 and the exact Fisher criterion.
RESULTS: It is shown that none of the tests used has 100% reliability, but the consistent application of some of them can successfully improve the diagnosis of idiopathic PFOL. When comparing the results of a number of tests, such as the Fukuda walking test and / or the Babinsky-Weil walking test, audiometric tests with head clone and hyperventilation, the test of fluid injection into the external auditory canal and the test of J. Frasser & L. Flood, it was found that the average prognostic value of a positive result was 87.3%, which is statistically significantly higher than the average result (47.9%) for other samples.
CONCLUSIONS: Correlations of the results of simple vestibulometric and audiometric tests allow us to recommend them to improve the diagnosis of idiopathic perilymphatic fistulas of the labyrinth windows. The possibilities of modern electrophysiological audiological research methods are subject to further study.
