For about ten years, we have developed our surgical operation and clinic job at Sobrapar Hospital and we have had the opportunity of follow a great number of "Cranium-synostoses" holder patients, this pathology has high complexity, and needs multidiscipline following by a highly qualified personal group. "Cranium-synostoses" is the name of the anomalies that show up premature ossification of cranio bones suture and of the face. This disturb can occur in a complete or partial way, as can implicate one or more sutures. The degree of the implication and the suture involved show up itself in the most diverse clinic forms, it can compress the brain, obstructing its growing for this we named "Cranium-synostoses", occasioning deleterious effects upon the Central nervous system. Those forms, sometimes bizarre, that the cranium change was known many years ago, it was described in the antiquity by Hipocrates.The aim of this study is to evaluate the correlations between the liquor pressure into the internal spinal medullary duct, and the cranium, in the immediate moment before of surgery for reduction compress craniectomy. As seen, the technical difficulties and controversies found in the specific literature related to surgical indication to uncompress the encephalon and there being possibility of knowing the size of intracranial pressure with a simple lumbar puncture with the direct measurement of pressure inside the internal spinal medullary duct, this make easy the indication of the surgical proceeding. There were operated ten patients with "Cranium-stenosis", and there being under register the liquor pressure by lumbar puncture and for cranium trepaning moments before of the procedure a reduction compress craniectomy. After statistics analysis results, we observed there is significant correlation between the liquor pressure into the internal spinal medullary duct and intracranial, in the patients with "Craniumstenosis", this enable us to quantify and to diagnose the intracranial pressure without the cranium trepanning. However, the surgery of reduction compress craniectomy show up it self decreasing expressively the levels of liquor pressure into the both chambers in the right after post-operative.
