Background and objectives : Craniosynostosis is a congenital disorder in which one or more cranial sutures are closed prematurely. Therapy consists of an endoscopic assisted repair of craniosynostosis and postoperative helmet remoulding therapy. The goal of this study was to develop a new method to evaluate the therapy of craniosynostosis.
Method : For evaluation, three-dimensional (3D) photographs of the patients were acquired. Photographs were taken preoperative and with different time intervals postoperative. A control group was formed with 100 3D photographs of Caucasian infants in the range of 3–18 months of age. In order to compare the results to conventional measurement methods, the Cranial Index and Head Circumference were calculated for each model. Principal Component Analysis (PCA) was applied for a more advanced 3D evaluation.
Results : This new method is able to evaluate the development of the patients’ crania in 3D. The PCA analysis indicates how much and where the crania of the patients evaluated more towards normal proportions during the treatment.
Conclusion : In this study a model was created for 3D comparison of head shapes. Using this new method it is possible to accurately evaluate changes due to treatment and compare them to the normal standards.
