Imaging of Cholesteatomatous and Non-Cholesteatomatous Middle Ear Disease,important to consider them as two completely different diseases. In contrast to acute otomastoid diseases that usually develop in the well-pneumatized mastoid of a child, chronic otitis media is most often seen in the more sclerotic mastoid and on the basis of dysfunction of the eustachian tube.

It is estimated that approximately 5% of patients with closed head injury and 40% of patients with basilar skull fracture demonstrate a fracture of the temporal bone which is bilateral in 10-30% of cases (.; .). More than 80% of patients are males and the most common mechanisms of i

Acute Otomastoiditis and Its Complications,astoid cell, communicates with the epitympanic portion of the middle ear cavity. The middle ear and adjacent pneumatized portions of the temporal bone are subject to bacterial invasion via the eustachian tube. When a mild infection occurs pain will be present for a short period, the tympanic membran

The process can become quiescent at anytime or may become reactivated, in a way that oto sclerotic foci commonly contain both active and inactive regions (.).

Pneumatization of the petrous apex is present in 33% of all temporal bones, and of these, all parts of the apex are p

Imaging of Facial Nerve Pathology,ate with a large etiological diversity. Contrary to the frequency of Bell’s palsy, the most common inflammatory disease involving the facial nerve, tumoral pathology accounts for only 5% of peripheral facial palsies.

Using dedicated computer programs it is possible to fly through or around 3D objects; the anatomical structure to display from the inside is selected by means of a data-set segmentation obtained with 3D processing techniques based on surface or volume rendering.
