Аннотация
OBJECTIVE: Our aim was to evaluate the validity and reliability of clinically relevant tests in the diagnosis of Menière's disease (MD) according to the criteria formulated during 2015 as well as their efficacy in detecting endolymphatic hydrops (EH). The focus was on: three-dimensional fluid-attenuated inversion recovery-SPectral Attenuated Inversion Recovery (3D-FLAIR-SPAIR) sequences using 3 Tesla magnetic resonance imaging (3T MRI) performed 24 hours after intratympanic Gadolinium injection (IT-Gd) in comparison with the functional tests pure tone audiometry (PTA), caloric test, video head impulse test (vHIT), and cervical-vestibular-evoked-myogenic-potentials (cVEMP).
STUDY DESIGN: Retrospective study.
SETTING: Tertiary care center.
PATIENTS: Primary eligibility criteria were given clinical suspicion of MD and the performance of an IT-Gd MRI leading to a group of 31 patients and 52 ears to be analyzed separately.
MAIN OUTCOME MEASURE (S): Reanalysis of the raw diagnostic data leading to comparability of IT-Gd MRI, PTA, caloric test, vHIT, and cVEMP concerning their valency for clinically diagnosed MD and quantifiability of EH.
RESULTS: Considering sensitivity, specificity, and the likelihood-ratio only the IT-Gd MRI displayed results qualifying it as a viable device for MD-diagnostics in regards to the criteria of 2015 (p = 0.01), it even provides direct imaging evidence for the underlying pathology of the disease. Furthermore, the comparison between MRI images and test results of caloric test, vHIT and cVEMP revealed that neither of these diagnostic functional tests serves as a reliable indicator for EH.
CONCLUSIONS: It appears that the diagnosing process of MD would benefit from turning IT-Gd MRI into a standard diagnostic procedure in cases of suspected MD, displaying better results than caloric test, vHIT, and cVEMP.
