The techniques and applications of 3-dimensional (3D) printing have progressed at a fast pace. In the last 10 years, there has been significant progress in applying this technology to medical applications. We present a case of osteogenesis imperfecta in which treatment was aided by prospectively using patient-specific, anatomically accurate 3D prints of the calvaria. The patient-specific, anatomically accurate 3D prints were used in the clinic and in the operating room to augment patient education, improve surgical decision making, and enhance preoperative planning.
A 41-year-old woman with osteogenesis imperfecta and an extensive neurosurgical history presented for cranioplasty revision. Computed tomography (CT) data obtained as part of routine preoperative imaging were processed into a 3D model. The 3D patient-specific models were used in the clinic for patient education and in the operating room for preoperative visualization, planning, and intraoperative evaluation of anatomy. The patient reported the 3D models improved her understanding and comfort with the planned surgery when compared with discussing the procedure with the neurosurgeon or viewing the CT images with a neuroradiologist. The neurosurgeon reported an improved understanding of the patient's anatomy and potential cause of patient symptoms as well as improved preoperative planning compared with viewing the CT imaging alone. The neurosurgeon also reported an improvement in the planned surgical approach with a better intraoperative visualization and confirmation of the regions of planned calvarial resection.
The use of patient-specific, anatomically accurate 3D prints may improve patient education, surgeon understanding and visualization, preoperative decision making, and intraoperative management.
三维（3D）打印技术及其应用发展迅速。在过去十年中，将该技术应用于医学领域取得了显著进展。我们报告一例成骨不全病例，其中前瞻性地使用患者特异性、解剖结构精确的颅骨3D打印模型辅助治疗。这些患者特异性、解剖结构精确的3D打印模型在临床和手术室中用于加强患者教育、改善手术决策并完善术前规划。
一名41岁患有成骨不全且有广泛神经外科手术史的女性前来进行颅骨修补术翻修。作为常规术前影像检查一部分所获得的计算机断层扫描（CT）数据被处理成一个3D模型。这些患者特异性3D模型在临床用于患者教育，在手术室用于术前解剖结构可视化、规划及术中评估。患者报告称，与与神经外科医生讨论手术过程或与神经放射科医生查看CT图像相比，3D模型让她对计划中的手术有了更好的理解并感到更安心。神经外科医生报告称，与仅查看CT影像相比，对患者的解剖结构及患者症状的潜在原因有了更好的理解，术前规划也得到了改善。神经外科医生还报告称，计划中的手术入路有所改进，术中对计划进行颅骨切除区域的可视化及确认更好。
使用患者特异性、解剖结构精确的3D打印模型可能会改善患者教育、外科医生的理解及可视化、术前决策和术中管理。
