High-resolution computed tomography of the temporal bone: its role in the evaluation of middle ear disease.

High-resolution computed tomography (CT) was performed on the temporal bones of 93 patients in conjunction with pluridirectional tomography. The majority of the patients were scanned on the prototype Pfizer 0200 FS second-generation scanner, modified to meet the demands of high-resolution scanning. Images from this relatively economical scanner are almost comparable to those obtainable with the GE CT/T 8800 scanner in spatial and contrast resolution. CT scans of the temporal bone were found to be more sensitive than pluridirectional tomography in visualizing fractures and soft tissue masses in the middle ear, including fluid levels and tympanic membrane swelling. It is concluded that high-resolution CT of the temporal bone will probably soon entirely replace pluridirectional tomography.

Hemifacial spasm caused by a tortuous vertebral artery: MR demonstration.

Hemifacial spasm is a symptom complex comprising involuntary, painless spasms of the orbicularis muscle that may progress to involve all facial muscles. It is frequently the result of compression of the facial nerve at its root exit zone from the brain stem by vascular loops or aneurysms of the posterior inferior cerebellar artery, anterior inferior cerebellar artery, vertebral artery, or cochlear artery. Coronal and axial T1-weighted images clearly depict the course of the facial nerve from the brain stem to the internal auditory canal and its relation to the vertebrobasilar system. This case demonstrates the magnetic resonance appearance of a tortuous vertebral artery and its relationship to the facial nerve in a patient with long standing hemifacial spasm.
