DISCLOSURES: The authors declare neither financial support, sponsorship nor conflict of interest. ABSTRACT Background: Petrous bone trauma is the sequel of blunt head injury and can have life threatening complications resulting in immediate mortality. Early detection and good knowledge of the Computed Tomography (CT) findings ensure prompt treatment of both fractures and complications. Objectiv...

The aim of this study was to present a comprehensive three-dimensional (3D) morphology of the petrous bone with computer image-processing technology, which could be beneficial for the teaching of anatomy and for surgical procedures. The unstained celloidin sections of human temporal bone were digitized with high resolution and quality, and then processed with Amira® software to include alignmen...

Large-scale genomic analyses of ancient human populations have become feasible partly due to refined sampling methods. The inner part of petrous bones and the cementum layer in teeth roots are currently recognized as the best substrates for such research. We present a comparative analysis of DNA preservation in these two substrates obtained from the same human skulls, across a range of differen...

The aim of this study was to evaluate and compare organ doses delivered to patients in wrist and petrous bone examinations using a multislice spiral computed tomography (CT) and a C-arm cone-beam CT equipped with a flat-panel detector (XperCT). For this purpose, doses to the target organ, i.e. wrist or petrous bone, together with those to the most radiosensitive nearby organs, i.e. thyroid and ...

Congenital cholesteatoma of the petrous bone, though originating in childhood, has often a delayed diagnosis due to its poor symptoms and can grow achieving great extension. When asymptomatic or pauci-symptomatic, the diagnosis is incidental and purely radiological. Leaving the lesion untreated implies an inexorable progression leading to extensive erosion of the petrous bone and cranial nerves...

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...

Glomus jugulare is a rare slow growing tumor occurring within the jugular foramen that rarely presents with isolated symptoms. Although histologically benign, these tumors are locally destructive because of their proximity to the petrous bone, the lower cranial nerves, and the major vascular structures (Miller et al. (2009) and Silverstone (1973)). We wish to report a glomus jugulare tumor erod...

BACKGROUND Giant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. The petrous portion of the temporal bone forms a rare location for this tumor. CASE PRESENTATION The authors report a case of a large giant cell tumor involving the petrous and squamous portions of the temporal bone in a 26 year old male patient. He presented with right side sever...

We reported three cases with adenocarcinomas of the lung, prostate and stomach, which metastasized to the temporal bone. Two of them had proven adenocarcinoma of the lung and stomach, respectively at the time of the diagnosis of the temporal bone tumor. But the other patient had no known primary malignancy when the tumor in the petrous apex was demonstrated radiologically. First he underwent bi...

essential for the congenital type of cholesteatoma particularly in the petrous pyramid. Magnetic resonance has largely replaced CT for the soft tissue demonstration of masses in the petrous temporal bone and posterior cranial fossa particularly when assisted by Gadolinium enhancement. GdMRI is now the definitive investigation for acoustic neuromas although adequate preliminary screening is nece...
