Head trauma causing perilymphatic fistula

Objective Head trauma can be classified into four groups in terms of its central affection from concussion to traumatic brain injury (TBI) Grade I to III. The affection of the labyrinthine receptors by head trauma is known and can affect the cochlea, the semicircular canals and the otolith organs. So far temporal or permanent structural lesions by a concussion of the labyrinth are assumed to be the underlying mechanism of functional impairment. Rarely temporal bone fractures are observed. Cochlin tomoprotein ELISA allows for the first time an objective evaluation of a perilympatic fistula by a microfracture or lesion of the round or oval window. The aim of this study was to evaluate the occurrence of perilympatic fistula in patients with minor head trauma.
