Nautilus: Dynamic Craniotomy; New Surgical Technique and Preliminary Results
Being the craniostenoses sutural basically a disease, the fact that the brain being trapped in an enclosure that does not have complacency required to accompany their growth constitutes the challenge of treatment, which aims to restore the complacency of the suture and correct the stenotic compensatory cranial deformity.
This paper proposes the combination of a helicoid osteotomy distraction osteogenesis provided by the use of springs distracting.

|Official Title:||Nautilus: Dynamic Craniotomy; New Surgical Technique and Preliminary Results|
- Nautilus: dynamic craniotomy; new surgical technique and preliminary results [ Time Frame: Up to 3 years ] [ Designated as safety issue: Yes ]This study proposes to analyze the cranial remodeling achieved through the use of a dynamic craniotomy, without detachment of the dura mater in cranial deformities caused by craniosynostosis.
- cranial remodeling [ Time Frame: Up to 3 years ] [ Designated as safety issue: Yes ]Quantify the results of cranial remodeling by osteotomy helicoid-shaped Nautilus by clinical and CT in 6 months after the procedure, by 3 surgeons at different times - The skull shape, postoperatively, will be assessed independently by four surgeons, who will use the following scale results: insufficient when there was no attenuation of preoperative deformity, partial, when the correction happened, but was not able to capture all the characteristics of the deformity; appropriate, when there was complete remission of cranial deformity.

Procedure: dynamic craniotomy
Surgical technique of craniotomy spiral without detachment of dura mater
As demonstrated by some authors, the curved shape of the helix fits perfectly the remodeling of a curved surface as well as the skullcap. If you do not receive fixation, however, trace the helicoid of the bone osteotomy can turn on a spring that can expand or contract depending on the direction of the force that is received. This form of osteotomy was therefore chosen by the authors to induce bone compliance areas of secondary defect that should expand or compress indirectly during the process of dynamic remodeling of primary defect with springs.
