title: 3D-FLAIR MRI in facial nerve paralysis with and without audio-vestibular disorder.
abstract: CONCLUSIONS
  Among patients with facial nerve paralysis, significant difference was observed on three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI) between those with and without audio-vestibular disturbance. This MRI technique may contribute to elucidation of the pathology of Ramsay Hunt syndrome and Bell's palsy.
  
  
  OBJECTIVE
  To evaluate the 3D-FLAIR MRI findings in patients who have facial nerve paralysis with and without audio-vestibular disturbance.
  
  
  METHODS
  3D-FLAIR MRI was performed with and without gadolinium enhancement in 15 patients (5 men and 10 women) with unilateral facial nerve paralysis: 3 patients with Ramsay Hunt syndrome, 3 patients having facial nerve paralysis with hearing loss or vertigo without vesicles, and 9 patients with Bell's palsy.
  
  
  RESULTS
  Five of the six patients with audio-vestibular disturbance showed high signals in the inner ear on precontrast 3D-FLAIR. In comparison, among nine patients with Bell's palsy, only one patient showed high signals in the inner ear on precontrast 3D-FLAIR (p < 0.05).
