title: [Neurovascular structures of the posterior surface of the petrous pyramid: correlation with the approaches of the cerebellopontine angle].
abstract: A topographic study of posterior surface of the petrous pyramid was performed in 20 human cadaveri heads. The distances between the neurovascular structures were measured in the points where they contact the posterior surface of the petrous pyramid. The study also points out the relationship between the bone landmarks and the transverse and the superior petrous sinuses. The result of this study was correlated with the approaches to the cerebellopontine angle.
