MRI axial scans (left column), and the corresponding MRI colored images (right column) of patient no. 7 (Table 1) in the EDB group with right MD A prior to surgery, B 2 weeks after surgery, and C 16 months after surgery are shown. A 3D-real IR MRI revealed a significant EH both in the cochlea (white arrow) and vestibule (red arrow) in the right ear, and no pathological findings were identified in the left ear. B Compared with the imaging in the same slice level in the first MRI examination (A), the second MRI examination showed that the EH tended to temporarily increase both in the cochlea (white arrow) and the vestibule (red arrow). C The third MRI examination showed complete reversal of vestibular hydrops (red arrow) and downgrading of cochlear hydrops (white arrow) from grade II to grade I.
