“…The surgical correction of craniosynostosis is a complex procedure and presents as an interdisciplinary challenge. What is also important is that the procedure is comparatively rare even at specialized centers [9,16,17]. Early surgery is beneficial with decreasing risks for intracranial hypertension and subsequent developmental delay.…”

Craniosynostosis is a skull malformation because of premature fusing of one or more cranial sutures. The most common types of craniosynostosis are scaphocephaly (with the sagittal suture fused) and trigonocephaly (with the metopic suture fused). In this paper we describe and discuss how finite element analysis and three-dimensional modeling can be used for preoperative planning of the correction of craniosynostosis and for the postoperative evaluation of the treatment results. We used the engineering software MIMICS MATERIALISE to obtain three-dimensional geometry from computed tomography scans, and applied finite element method for the sake of biomechanical analysis. These simulations help to improve the surgical treatment, making it more accurate, safer, and faster.

“…By performing measurements on, e.g., cephalograms a more reproducible result can be achieved [10,15,17]. Determination of total intracranial volume has been performed for the purpose of surgical planning [13]. For the purpose of systematic and reproducible evaluation of the result of operation for craniosynostosis, we developed a computer-based tool for determination of total and frontal intracranial volume.…”

“…Bi-dimensional measurements, e.g., of the cranial index, or more recently proposed measurements are less subjective but will not measure the change in intracranial volume [12]. Threedimensional analyses of metopic synostosis have been performed for determination of the entire intracranial volume before the operation and for the purpose of surgical planning [13,14]. Until now, however, no suitable tool for systematic evaluation of the change in intracranial volume, in response to operation, has been put forward.…”

The aim of this project was to develop a tool for systematic evaluation of volumetric changes after surgery for craniosynostosis. A computer program using MATLAB was developed to measure total intracranial volume and frontal volume, anterior to the coronary sutures, by multiplying the area with slice thickness of each slice from just above foramen magnum to just beneath the vertex in CT examinations. The ratio between frontal volume and total volume was used for evaluation of the clinical result in 12 patients operated on for metopic synostosis. In 0.625 and 5 millimetre slices the coefficients of variation were 0.00049 and 0.00058, respectively, for measurements of total volume. The highest coefficient of variation was found in postoperative measurements of the frontal volume and was 0.014 in 0.625 millimetre slices. Measurements in 5 millimetre slices resulted in 3.8% ± 1.5% (mean ± SD) lower total volumes and 5.8% ± 5.3% lower frontal volumes than measurements in 0.625 millimetre slices. In patients operated on for metopic synostosis the ratio between frontal volume and total volume increased 25% ± 16% for patients operated on with cranioplasty in combination with a spring (n = 6) and 20% ± 13% for patients operated on with cranioplasty in combination with a bone transplant (n = 6). In summary, this study has developed a tool that can determine frontal and total intracranial volume with little variation. This tool can be used for systematic evaluation of the result of the operation for metopic synostosis.

Advances in imaging and computer technology have led to the development of different simulation models to complement traditional surgical training. Sophisticated virtual reality (VR) simulators with haptic feedback and impressive imaging technology have provided novel options for training in neurosurgery. Breakthrough training simulation using 3D printing technology holds promise for future simulation practice, proving high-fidelity patient-specific models to complement residency surgical learning.

3D visualization and simulation of frontoorbital advancement in metopic synostosis

Abstract: Computer-assisted postprocessing and simulation is a useful tool for surgical planning in craniosynostosis surgery. The time-effort for segmentation currently limits the routine clinical use of this technique.
