AbstractA dull head injury can lead to isolated damage of the inner ear (cochlear labyrinthine concussion) or damage of the otolithe organ (vestibular labyrinthine concussion) due to a bone conduction pressure . A typical sign is a high frequency SNHL in form of a c5-dip. The c5-dip can be bilateral or unilateral or different on each side - dependant on the side of injury. In case of a unilateral skull base fracture a contralateral labyrinthine concussion is also possible. Moreover a lot of cases also show an accompanying tinnitus. This knowledge is based on animal and human experiments, as well as data from clinical and medical report examinations over decades. It is important to differentiate between a SNHL caused by accident or uni- or bilateral endogenic degenerative hearing loss.© Georg Thieme Verlag KG Stuttgart · New York.
