He was a passing bit of biological noise in the city, with no real place in its petrous existence.

Anteriorly it extends to the apex of the petrous temporal.

Similar symptoms can also occur secondary to petrous fractures or to nasopharyngeal tumours.

It is separated from the posterior fossa by the clivus and the petrous crest.

At the tip of the petrous temporal bone it makes a sharp turn forward to enter the cavernous sinus.

Its superior and inferior (petrous) ganglia contain the cell bodies of pain fibers.

It is very small, and is usually regarded as a detached portion of the petrous ganglion.

The petrous portion is among the most basal elements of the skull and forms part of the endocranium.

The syndrome is usually caused by the spread of an infection into the petrous apex of the temporal bone.

The named branches of the petrous segment of the internal carotid artery are:

It lies above the malleolar folds attached directly to the petrous bone at the notch of Rivinus.

From Latin, petrous, meaning rocky.

Petrous portion can refer to:

He had staining of the petrous ridge of the temporal bones and mastoid air cells, bilaterally.

It is directed superiorly, as per its nomenclature, and posteriorly, nearly parallel to the posterior surface of the petrous bone.

"Petrous apex aspergillosis as a long-term complication of cholesterol granuloma: case report and review of the literature."

In radiology, oblique view of skull, to establish better views for petrous bone, bony labyrinth and internal auditory canal.

Petrous portion (Petrosal ridge)

Still not believing that he would find the rock anything but impenetrable or that he could ignore its petrous imperative, he stepped forward.

It had entered behind the right ear causing radial fractures and impacting and terminating in the right petrous region.

The petrosquamous suture is a cranial suture between the petrous portion and the squama of the temporal bone.

The tumor involves the endolymphatic sac, a portion of the intraosseous inner ear of the posterior petrous bone.

Involvement of the petrous segment of the carotid canal is associated with a relatively high incidence of carotid injury.

It enters the middle cranial fossa through the greater (superficial) petrosal foramen (on the anterior surface of the petrous temporal bone).

The patients chin rests on the image receiver, which tilts the head up allowing the orbits to be clear of the internal structure of the Petrous ridge.
