Head trauma, reported in sport injury and road accident analysis, frequently induce complex injury of Petrous bone. Such bone fractures are assumed to occur during lateral or posterior impact on the head. The location of the trauma on head structure, specifically on the Petrous bone area, concerns facial nerves, vestibule, cochlea, internal carotid artery. Over the lethal risk, the pathology associated to these injuries could be very severe from facial paralysis, vestibular trauma, tinnitus, deafness, vascular injuries and high blood pressure in skull. Hence in order to provide a better understanding of this trauma, based on recent advance in medical data processing, a detailed numerical model of the Petrous bone structure was built. Lateral impact simulation was performed, leading to investigate macroscopic damage process of Petrous bone trauma and their anatomical correlation with clinical potential pathologies.
