[The value of therapeutic arteriography in the treatment of tympano-jugular glomus tumours (author's transl)].

In this article, the authors stress three fundamental points in the diagnostic and therapeutic angiographic study of tympano-jugular glomus tumours. The first basic concept is the need for complete right, left, internal carotid, vertebral and external carotid angiographic examination. The latter must be selective, regardless of the information provided by common carotid arteriography. This implies prior knowledge of the different arteries which may "supply" the gloumus tumour. The second basic point is the concept of vascular compartment, , often mutually independent and vascularised by a single pedicle. The juxtaposition of the different vascular compartments gives the exact size of the tumour. The third important point concerns embolisation carried out at the same time as diagnostic angiography. This is invariably indicated on a pre-operative basis, except in two circumstances: --when the glomus, tumour is small and situated close to the drum of the tympanum, its surgical excision posing no problem of haemostasis under these circumstances: --when radiotherapy is envisaged as treatment of the glomus tumour when surgery is impossible. In this case, embolisation is contraindicated for two reasons: -radiotherapy is more effective when blood flow is preserved; -the risks of necrosis are increased.

The inclined lateral projection: a new view in temporal bone tomography.

Radiographic findings in the inclined lateral projection are presented. This view provides detail of the malleus and incus which is not provided on any other view and also preserves the visualization of temporal bone anatomy seen by routine lateral projection. The frequent occurrence of ossicular pathology in inflammatory and traumatic diseases of the ear requires the meticulous radiographic examination of the ossicles provided by this projection. Patient positioning is uncomplicated and comfortable.

Phlebographic appearance and pathogenesis of venous malformations in the orbit.

A retrospective clinical and radiographic analysis of 20 patients with orbital venous malformations was performed. The malformations were fed by other veins rather than arteries. They may nearly always be demonstrated by orbital or jugular phlebography, though occasionally they will fill only following direct puncture. There appeared to be varied etiologies. A few were related to trauma or to other causes of increased intraorbital pressure. There is an association with periorbital hemangiomas suggesting developmental or congenital origin.

Neuroradiology of the sphenoidal region.

The neuroradiological techniques employed in diagnosing a series of 54 lesions involving the superior orbital fissure and cavernous sinus (sphenoidal region) were reviewed in order to compare the value of sphenoidal tomography, pneumoencephalography, cerebral arteriography and sphenoidal venography. The patients included in the series exhibited clinical syndromes of sphenoidal region cranial nerve deficits. Confirmation of the sphenoidal region disorder was obtained in all cases. Of the four procedures, sphenoidal venography and basal tomography yielded the highest rate of positive studies.
