[Rupture of the round window membrane after slight head injury with flush of perilymph probably caused by large opening of aquaeductus cochleae (author's transl)].
A ringing deaf ear was noticed after slight head injury without loss of consciousness nor fracture of the skull. After performig tympanotomy a ruptured round window membrane with excessive flush of perilymph was found. We might rightly assume that this was induced by a large opening of aquaeductus cochleae combined with the force of inertia of the cerebral liquor and the direction of the push to the round window (blow behind the left ear).
