Abstract: Objective To explore the effects of 3D printing technique in the treatment of Craniostenosis in Children. Methods The clinical data of 15 cases underwent the operation with the guidance of 3d printing between September 2015 and August 2016 were analyzed retrospectively. Children underwent Computed Tomography （CT） and 3D reconstruction of the shell before operations, the imaging data was transferred into 3d printing data through professional software, the deformity was reconstructed on the computer and the 1：1 skull model was printed by 3d printing technology, then the model was used to communicate with patients and make operative plans. The operations were finished as predetermined design, and the cranium CT scan was performed to observe the clinical efficacy. Results Fifteen cases underwent operations successfully as predetermined design, operative time ranged from 1.5 to 3.5 hours. According to postoperative cranial CT imaging and realistic appearances, the results were satisfactory. All the children were followed up for 2 to 12 months, no obvious comphcations were observed, and the progress of language and intellectual development was obvious. Conclusion Making use of 3d printing technology in the treatment of craniostenosis of children could save the operation time, reduce the surgical trauma, ensure the enough intro-cranial volume and postoperative appearances, promote the brain development obviously, and drive the trend of personalized therapy.
