The authors report their experience of the antero-lateral bilateral approach for the treatment of inferior spinal cervical metastasis. They underline the effect of osseous posterior wall compression.
The authors report their experience of cervical foramina disk herniation. They underline the interest of C.T. scan for its diagnosis and use for the approach a combined antero- and lateral approach by diskoforaminotomy.
The authors report their experience of anterolateral bilateral approach of cervical spine. They underline the advantages and inconvenience of this route and discuss the indications.
The authors report their experience of radiculomedullary transposition for the treatment of neurological complications by kyphosis or kyphoscoliosis. They use a posterolateral approach by transversoarthropediculectomy. They underline the necessity to treat all etiopathological aspects.
The authors report the use of direct osteosynthesis for odontoid fractures by screw. The approach is a transcervical approach. Its advantages and inconvenients are reported. Its indications are discussed.
The authors describe the technique of orbito-fronto-temporo-pterional bone flap in block. They underline its interest for the treatment of aneurysms at an early stage because its angle is very tangential.
The authors describe the surgical technique of atlanto-axial fixation using a transcervical anterior approach. The cartilage of the articular processes of C1 and C2 are excised. A screw fixation of the articular processes is performed with two spongious screws. These are perpendicular to the articular surfaces. The trend is to obtain a bilateral articular fusion. The indications are discussed.

The authors describe an orbito-zygomatic-malar bone flap approach which gives lateral extra-cerebral access to the internal base of the skull. The technique is described, and some of the situations in which it has been used are discussed.
Tumours of the spine occasionally also present with an intra-thoracic extension. The authors report on a technique which permits the complete removal of these hourglass lesions at a single operation by transversoarthropediculocostectomy. Its advantages and disadvantages are discussed and the results in 6 patients presented.
Neurinomas of the trigeminal nerve are rare. Based on an analysis of the published cases and on six additional cases of our own classification into three types is proposed: Type I: neurinoma of the roots in the posterior fossa, Type II: neurinoma of the Gasserian ganglion, Type III: neurinoma of the trigeminal branches. This classification allows a better adaptation of the surgical procedure to the individual case. The trigeminal nerve originates from a sensory root and a motor root which emerge from the pons and gain the middle cranial fossa floor over the apex of the petrousrigde before forming the Gasserian ganglion. The three branches of the trigeminal nerve originate at the Gasserian ganglion. Neurinomas of this nerve are relatively rare, as there are only 183 published cases. A study of the literature reveals that their incidence among brain tumours is from 0.2 to 0.4% according to the authors. Based on the published material and six personal cases and also on the anatomical, clinical and neuroradiological findings three major types of neurinomas of the trigeminal nerve can be distinguished according to their origin: neurinomas developed in the posterior fossa (type I) on the nerve roots, neurinomas of the Gasserian ganglion (type II) developed in the temporal fossa and neurinomas of the branches of the trigeminal nerve (type III). Transitional forms between the various types are possible and express special conditions of development. Each of these topographical forms has a specific clinical and radiological picture and each requires specific surgical treatment. This will be demonstrated by analysing our own six cases and the cases reported in the literature.
Between 1960 and 1 June 1985, 21 patients were operated for thoracic disc herniations. The advent of new operative techniques (with transverso-arthropediculectomy) has brought about new indications in the management of such disorders. These new indications are important because such protrusions may be abruptly complicate by compression of blood vessels, which may produce abrupt and irreversible neurological deficit. The progress in the radiological examinations allows a more precise study of the topography and density of the hernia. Furthermore, the use of a surgical microscope and microsurgical techniques allow a surgical treatment without preoperative medullary angiography.
Surgery of the dorsolumbar spine is currently benefiting from diverse approaches and the advent of computed tomography. This report describes a bilateral posterolateral approach with transversoarthropediculectomy and corporectomy. The advantages and disadvantages of this approach and its indications are discussed.
A transsternal biclavicular approach to the anterior face of the upper thoracic spine (T-1 to T-4) is described, and the advantages, disadvantages, and indications of the technique are discussed.
Chemonucleolysis is widely used in the treatment of disease of the lumbar intervertebral disk. From a series of 34 patients the authors report their experience using this technique at the cervical level using aprotinin instead of chymopapain in cervical soft disk protrusion. They underline the technique, mechanism of aprotinin and indications.
