The authors describes the technique of mobilization of orbito-zygomatico-malar bloch. In some affections it is justiciable to use this approach which provides an excellent view of the lateral region of the skull base and permits the access to the base of the tumour in some indications and always extracerebral approach.
Two cases of intraspinal meningeal hemangiopericytomas are reported, one of which cervical and the other one dorsal with relapse. The anatomopathological features of the hemangiopericytomas are recorded and the nosological problems of their meningeal localizations are discussed. As in the case of intracranial meningeal hemangiopericytomas, the clinical, radiological and macroscopic features of intraspinal hemangiopericytomas--to the exception of a few particular cases--resemble those of other localizations of these tumours more than those of meningiomas, in the light of the review of twenty-eight cases to be found in the relevant literature. Treatment of such tumours hasn't as yet been well circumscribed. Surgical treatment may be facilitated by preoperative embolization. Radiotherapy must be associated to it, at least when removal is incomplete, because of frequent recurrence.
The mobilization of the medial fronto-orbital ridge improves the transbasal approach described by Derome. This one reported by Cophignon can be realized by a monobloc bone flap. The authors describe technical aspects and their experience of this route.
The authors report their experience of the intermaxillohyoido-retro-pharyngeal approach and acrylic prosthesis for metastasis of upper cervical spine. The underline the effect of osseous anterior compression and immediate stability obtained with this technique.
The authors report a case of choroid plexus papilloma developped in the fourth ventricle. After complete surgical resection, two local recurrences of the tumor occurred, and required new surgical procedures. Eight years after the first operation, a papilloma of the right lateral ventricle was resected. The histological examination showed benign choroid plexus papilloma after each operation. Recurrence and seeding of benign choroid plexus papillomas are infrequent in the literature. For this reason, a long-term follow-up, by clinical examination and CT scan, is necessary for those patients.
A technique is proposed for the anterior approach to the cervicothoracic intervertebral joint which allows access to the first four thoracic vertebrae and is based on the insertion of a sterno-biclavicular piece respecting insertion of sternocleidomastoid muscles.

Thirteen patients with thoracic disc herniation have been operated on between 1960 and 1984. Nine presented with a progressive cord compression syndrome affecting sensory function more than motor. Four patients presented with acute cord compression. During this period, the authors have abandoned medullary angiography and myelography. The diagnosis is now based on computerised myelotomography. Three cases were treated by laminectomy with two postoperative deteriorations. Two cases were treated by a transthoracic approach which seemed to be too risky. Eight cases were treated through a postero-lateral approach, six being through a transverse arthropediculectomy using a microscope for better dissection of the vessels and Harrington rods to avoid secondary kyphosis. Seven of 9 cord syndromes were improved. Four cases with predominantly radicular syndromes were all improved.

In the technique of syringoperitoneal shunting described, a small diameter silicone catheter with lateral openings is introduced through the spinal cord into the lower part of the syringomyelic cavity, then connected to a standard peritoneal shunt tube. Six patients were operated upon using this technique. No major post-operative complication was observed; one patient stabilized and 5 rapidly and distinctly improved. The best results were obtained in patients with sensory loss or arthropathy. It seems rational to apply this technique to active syringomyelia. Permanent shunting maintains low pressure in the cavity and attenuates the effects of sudden, physiological rises in CSF pressure, thus preventing progressive dissection of the nervous tissue.
We describe 5 patients with spinal epidural abscesses in whom computed tomographic scanning confirmed diagnosis without the use of myelography. One patient required urgent surgery because of rapidly deteriorating neurological status, but the other 4 were treated nonsurgically. The medical treatment of these patients and 9 others described in the literature consisted of antibiotics administered parenterally for a minimum of 8 weeks, followed by oral antibiotic therapy. Early diagnosis with computed tomographic scanning and a benign neurological state at the onset of treatment were associated with good results.
