Modulation of hearing function following the downgrading or upgrading of endolymphatic hydrops in Meniere’s disease patients with endolymphatic duct blockage
Fig 5
3D-real IR serial MRI scans of patient no. 14 (Table 1) with right MD.
(A1-3) prior to surgery, and (B1-3) 2 weeks, (C1-3) 10 months and (D1-3) 16 months after surgery. (A1-3) Serial MRI scans showing a significant EH in the vestibule (red arrow) and cochlea (white arrow) before surgery. (B1-3) Unchanged EH in the vestibule (red arrow) and cochlea (white arrow) 2 weeks after surgery. (C1-3) Reversal of vestibular hydrops and remaining grade II EH in the cochlea 10 months after surgery. (D1-3) Serial MRI scans showing a disappearance of vestibular EH (red arrow) and the reduction of cochlear EH (white arrow) 16 months after surgery. LSCC, lateral semicircular canal; 3D-real IR, three-dimensional real inversion recovery; MRI, magnetic resonance imaging; EH, endolymphatic hydrops; MD, Meniere’s disease.
