Tinnitus, hearing loss, and more rarely desiquilibrium are common sequela o
f temporal bone trauma. Hemotympanum may cause a transient and immediate co
nductive hearing loss. HRCT depicts ossicular dislocation (most frequently
incus), producing a long-term conductive hearing loss. Labyrinthine trauma
causing neurosensory hearing loss or/and acute vertigo may be depicted by M
RI, showing an abnormal non-enhancing high signal T1 of the membranous laby
rinthine fluid. MRI also may show low signal T1 and T2 fibrotic areas of th
e membranous labyrinthe, especially of interest if cochlear implant surgery
is planned. Perilymphatic fistulas are to be searched in case of fluctuant
hearing loss. Both HRCT and MRI may show window damage: filling of the tym
panic recess, rupture of the window membrane, intra-vestibular luxation of
the stapes, or occasionnaly pneumolabyrinth.
