    Abstract:
    PURPOSE: The aim of this work is to study otosclerotic patients by 3D-FLAIR (fluid attenuated inversion recovery) sequence magnetic resonance imaging (MRI) with and without Gadolinium administration (-/+ Gd), to understand whether there is a direct relationship between radiological findings at 3D FLAIR MRI sequences and some clinical features of otosclerosis, such as the presence and entity of sensorineural involvement, duration of disease, patient gender, and other factors. METHODS: 38 patients affected by different stages of unilateral or bilateral otosclerosis underwent 3D FLAIR MRI+/- Gd. 11 subjects with normal hearing, previously submitted to 3T MRI for other minor diseases, unrelated with otosclerosis, had been retrospectively enrolled as control group. RESULTS: We found significant correlations between 3D FLAIR MRI findings and some clinical features of otosclerosis, such as severity of cochlear damage (in terms of entity of sensorineural loss) and duration of disease. These findings indicate that at 3D-FLAIR MRI different patterns may depend on the level of blood labyrinth barrier damage in the cochlea, and be related to different stages of cochlear involvement in otosclerotic patients. CONCLUSIONS: We believe that our findings may contribute in understanding the pathogenesis of cochlear damage in otosclerosis and may have further prognostic value. Our results led us to consider the possible use of 3D-FLAIR sequences in monitoring the effectiveness of any medical therapy of otosclerosis and in selecting the patients eligible for treatment.
