Background: Resection of the petrous temporal bone to various degrees provides different levels of access to lesions of the posterior fossa. However, precise distances of petrosal bone are not still clearly described due to the numerous variations of them which may lead to serious complications during transpetrosal surgeries. Objective: Our objective was to evaluate different distances of tempo...

Osteomas of the petrous temporal bone are rare and seldom symptomatic. This report describes an osteoma of the internal auditory canal, causing compression of the eighth nerve, leading to auditory and vestibular complaints. The symptoms were abolished by surgical decompression of the internal auditory canal and removal of the osteoma.

We encountered a case of acquired perilymphatic fistula in which the origin of the disease, namely, the stapes begin medially displaced into the vestibule, was shown by thin-section CT. Accordingly, we recommend that every patient with suspected perilymphatic fistula of traumatic origin undergo high-resolution CT of the petrous bone.

Superior semicircular canal dehiscence (SSCD) is a rare entity recently described whose typical clinical symptomatology represented by dizziness triggered variation of pressure. We reported case SSCD which was diagnosed thanks to computed tomography (CT) scan the petrous bone conducted systematically in front mixed deafness with normal eardrum. The bilateral and revealed on left side perception...

Chondroid chordoma is a variant of chordoma; it may rarely involve the petrous temporal bone and has a high propensity for recurrence. Chordoma rarely metastasizes but it is, nevertheless, associated with a poor outcome. We report a rare case of chondroid chordoma with extensive recurrence and pulmonary metastases.
