3D设计和打印技术在眶距增宽手术中的系统应用

Systematic application of 3D design and 3D printing technology based on digital technology in the treatment of orbital hypertelorism

目的探讨数字化3D设计和打印技术在眶距增宽手术治疗中的系统应用流程及其精准性。方法自2015年1月至2019年12月,中国医学科学院北京协和医学院整形外科医院数字化整形中心将数字化技术系统性地应用于6例眶距增宽患者的手术治疗中,详细介绍了应用流程和具体操作,并对手术效果和手术设计的准确性进行三维定量化分析。结果6例患者通过数字化技术的手术治疗,降低了手术风险,提高了手术效果。三维测量结果的统计学分析显示,与术前相比,术后眶内侧壁间距、内眦间距和额鼻角均获得了明显改善(P<0.05)。与实际手术结果相比,手术设计的眶内侧壁间距具有很高的准确度(P>0.05),但是手术设计的内眦间距和额鼻角精准性欠佳(P<0.05)。结论将数字化3D设计和3D打印技术系统应用于眶距增宽症的手术治疗,有助于降低手术风险,提高截骨精度,定量评价获得了更满意的手术效果。

Objective To explore an application process and accuracy of 3D design and 3D printing technology in the treatment of orbital hypertelorism.Methods From January 2015 to December 2019,the digital technology was applied in 6 patients with orbital hypertelorism.The application process and detailed operation were introduced.The surgical outcome and accuracy of surgical design underwent the 3D quantitative analysis.Results Six patients were provided surgical intervention with digital technology,which reduced operation risk and achieved excellent surgical outcomes.Statistical analysis of 3D measurement showed that the index of IOD,ICD and FNA was significantly improved after operation(P<0.05).Surgical design of IOD had high accuracy compared to the actual surgical outcome(P>0.05).However,the accuracy of surgical design of ICD and FNA before surgery was lower than expectation(P<0.05).Conclusion The application of 3D design and 3D printing technology in the treatment of orbital hypertelorism was helpful to reduce surgical risk,improve accuracy of osteotomy,quantitatively evaluate the surgical outcomes and obtain satisfactory efficacy.
