Reduction of operating time and blood transfusion for craniosynostosis by simulated surgery using three-dimensional solid models.

Abstract

Preoperative planning of craniofacial synostosis can be achieved through the use of two- or three-dimensional (3D) computed tomography (CT) images and by 3D solid models. The advantage of using 3D models was evaluated by calculating the amount of blood transfused and the operating time for 36 craniosynostosis procedures, 21 planned with 3D models and 15 with CT images performed in the past 7 years. The use of 3D models reduced both blood loss and operating time for fronto-orbital advancement with reshaping, LeFort III advancement, and LeFort IV minus Glabellar advancement; blood loss for fronto-orbital advancement without reshaping; and operating time for total cranial reshaping.
