3D打印技术在儿童狭颅症矫治中的应用研究

目的探讨应用3D打印技术辅助儿童狭颅症矫治的效果。方法回顾性分析2015年9月至2016年8月,应用3D打印技术辅助手术的15例狭颅症患儿。术前对患儿行头颅CT扫描进行三维颅骨重建,应用3D打印技术对畸形进行模拟整复,并打印1∶1的颅骨模型。术前应用模型与家属沟通并制定手术计划,术后行三维头颅CT观察矫治效果。结果 15例患儿均成功按预定设计完成手术,手术时长1.5~3.5 h。术后患儿头颅外观及三维头颅CT均显示手术效果良好。术后随访2~12个月,无明显并发症,患儿语言及智力发育进步明显。结论将3D打印技术应用于儿童狭颅症的矫治,可节省手术时间,减小手术创伤,保证了足够的颅腔容积,术后头颅外形良好,明显促进脑部发育,有利于推动个性化治疗。

The Effects of Printing Technique in the Treatment of Cranlostenosis in Children

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.
