Computer Supported Pre-operative Planning of Craniosynostosis Surgery: a Mimics-integrated Approach
نویسندگان
چکیده
In order to correct functional and aesthetical aspects of malformations as caused by craniosynostosis, skull reconstruction is required. Because of the complexity of the surgery, preoperative planning is unavoidable. Current and previously developed planning environments allow an iterative sequence of osteotomies and repositioning trials in order to search for the optimal reconstruction plan. Nevertheless, they often lack the opportunity to simulate neonatus cranial bone bending [1] as well as to transfer the simulated surgery to the operation room on a cheap but accurate and easy to handle basis [2]. This study combines existing planning utilities in the commercial Mimics® environment with newly developed tools, implemented in Matlab®. Skull reconstruction planning is done on an outer bone surface model generated partly in Mimics®, partly in Matlab® by the use of Mimics® MedCAD, measurement and simulation tools. For each resected/osteotomized bone part, the presented Matlab® procedures provide virtual bone bending based on reference data and finally generate surface based bone cutting guides, also denoted templates. The clinical feasibility of using templates in combination with Mimics® planning screenshots is validated by three successful clinical cases which result in considerable surgery time reduction and optimal results.

The integrated planning of distribution system reveals a complex and non-linear problem being integrated with integer and discontinues variables. Due to these technical and modeling complexities, many researchers tend to optimize the primary and secondary distribution networks individually which depreciates the accuracy of the results. Accordingly, the integrated planning of these networks is p...
متن کاملBiomechanical aspects of preoperative planning of skull correction in children with craniosynostosis.
Craniosynostosis is a birth defect that causes one or more sutures on a baby's head to close earlier than normal. In effect the growing brain determines an abnormal skull shape and, which is more important and more dangerous, it causes an elevated intracranial pressure. The only treatment for children with craniosynostosis is surgical cranioplasty. More extensive procedures yield excellent resu...

Background: Intracranial pressure (ICP) control is one of the anesthesiologist challenges in craniosynostosis repair surgery, especially in multiple sutures involvement. The aim of this study was comparing the effect of two anesthesia methods including inhalation with hyperventilation and total intravenous anesthesia (TIVA) on ICP control and surgeon satisfaction in pediatrics with craniosynost...
