[Stereotaxic technics with an open skull in the treatment of space-occupying brain lesions].
When intra-cerebral space-occupying lesions are small or when they are deeply located in the brain parenchyma, it is sometimes difficult to localize them at surgery or to design the most direct and least hazardous surgical approach. Therefore we have developed a method which combines conventional neurosurgical techniques with craniotomy using stereotaxic guidance. We have used the Brown-Roberts-Wells (B.R.W.) stereotaxic system which allows for CT scan or MRI guidance and does not interfere with the absolute sterility mandatory every time a flap is created. Eleven patients were operated on using this method. The deep tumors were approached through a linear incision of the cerebral cortex; then a needle fixed in the right position on the arc system of the B.R.W. was inserted toward the surface of the lesion; the exposure was finally widened by the inflation of a rubber balloon set on the stereotaxic needle. The post-operative course was very uncomplicated in all these patients. No permanent post-operative neurological worsening was observed, even after the removal of an intra-thalamic tumor.
