摘要

研究设计:回顾性队列研究.目的:3D打印技术在颅颌面(CMF)手术中得到了广泛应用,但外科医生在急性创伤环境中实施该技术仍存在困难,因为报告中经常遗漏关键信息。因此,我们为各种颅颌面骨折开发了内部打印流水线,并描述了及时打印出手术模型所需的每个步骤:确定并分析了2019年3月至11月期间在一级创伤中心进行急性创伤手术时需要内部3D打印模型的所有连续患者:结果:确定了需要打印 25 个内部模型的 16 名患者。虚拟手术规划时间从 0 小时 08 分钟到 4 小时 41 分钟不等(平均 = 1 小时 46 分钟)。每个模型的整体打印阶段(预处理、打印和后处理)从 2 小时 54 分钟到 27 小时 24 分钟不等(平均 = 9 小时 19 分钟)。整体打印成功率为 84%。每个模型的灯丝成本在 0.20 美元到 5.00 美元之间(平均 = 1.56 美元):本研究表明,内部三维打印可在相对较短的时间内可靠完成,因此可将三维打印用于急性面部骨折治疗。与外包相比,内部打印可避免运输延误,并能更好地控制打印过程,从而缩短流程。对于时间紧迫的打印,还需要考虑其他耗时的步骤,如虚拟规划、三维文件预处理、打印后处理和打印失败率。

Printing in Time for Cranio-Maxillo-Facial Trauma Surgery: Key Parameters to Factor in.

Study design: retrospective cohort study.

Objective: 3D printing is used extensively in cranio-maxillo-facial (CMF) surgery, but difficulties remain for surgeons to implement it in an acute trauma setting because critical information is often omitted from reports. Therefore, we developed an in-house printing pipeline for a variety of cranio-maxillo-facial fractures and characterized each step required to print a model in time for surgery.

Methods: All consecutive patients requiring in-house 3D printed models in a level 1 trauma center for acute trauma surgery between March and November 2019 were identified and analyzed.

Results: Sixteen patients requiring the printing of 25 in-house models were identified. Virtual Surgical Planning time ranged from 0h 08min to 4h 41min (mean = 1h 46min). The overall printing phase per model (pre-processing, printing, and post-processing) ranged from 2h 54min to 27h 24min (mean = 9h 19min). The overall success rate of prints was 84%. Filament cost was between $0.20 and $5.00 per model (mean = $1.56).

Conclusions: This study demonstrates that in-house 3D printing can be done reliably in a relatively short period of time, therefore allowing 3D printing usage for acute facial fracture treatment. When compared to outsourcing, in-house printing shortens the process by avoiding shipping delays and by having a better control over the printing process. For time-critical prints, other time-consuming steps need to be considered, such as virtual planning, pre-processing of 3D files, post-processing of prints, and print failure rate.
