[Role of helical computed tomography in petrous bone trauma: about 12 cases at the University Hospital Ibn Rochd of Casablanca].

Temporal bone injuries occur in 14-22% of skull fractures occurring due to head trauma. The purpose of this study is to understand the role of helical computed tomography in petrous bone trauma and to show the different types of fractures and the associated lesions. We conducted a retrospective study of 12 patients with petrous bone trauma (including 10 men and 2 women) over a period of 14 months.
