【摘要】：目的设计并制作可用于眼眶爆裂性骨折修复手术临床与教学的3D眼眶模型。方法选取2016年11月至2017年2月在山东文登整骨医院眼科确诊的10例(10眼)眼眶下壁爆裂性骨折患者眼眶CT检查DICOM格式的原始CT数据。使用Mimics软件对二维CT图像依次进行阈值选取、区域增长、处理模具、多层编辑修饰等过程,最终获得完整的眼眶爆裂性骨折3D模型,通过3D打印机打印出患者的3D眼眶模型,测量各模型的具体大小,分别将模型与患者的眼眶解剖标志测量数据进行配对t检验。由高年资眼眶外科医师对打印的眼眶爆裂性骨折模型和外科种植体模型进行模拟手术操作。结果共有10例眼眶下壁爆裂性骨折患者,其中男5例(5眼)、女5例(5眼)。3D模型和外科种植体模型成功设计并打印。全部男性组和女性组眼眶爆裂性骨折3D打印模型与CT测量的眼眶数据基本相吻合,差异均无统计学意义(均为P0.05)。由高年资眼眶外科医师在模拟手术室手术环境下向住院医师示范眼眶骨折修复术手术操作,3D打印的眼眶爆裂性骨折模型可成功用于模拟手术操作和教学示范。结论 3D打印的眼眶爆裂性骨折模型能够真实还原患者眼眶损伤情况和眼眶解剖细节,为医师提供了立体直观的术前设计的模型,对了解眼眶爆裂性骨折的波及范围和手术教学模拟具有积极意义。
[Abstract]:Aim to design and manufacture can be used for the 3D orbital fracture model and clinical teaching of surgical repair of orbital blowout. Methods from November 2016 to February 2017 in 10 cases with Shandong Wendeng osteopathic hospital (10 eyes) of original CT data under the orbital blowout fracture with orbital CT examination DICOM format. The two-dimensional CT image by threshold selection the use of Mimics software, regional growth, processing mould, multilayer editing process, finally complete the orbital blowout fracture by 3D model, 3D printer to print out the 3D orbital model of patients, the specific size measurement model, respectively model and patients with orbital anatomy sign measurement data was analyzed by paired t test by high. The surgeon to print the seniority of orbital orbital blowout fracture model and surgical implant model to simulate the operation. Results a total of 10 cases of inferior orbital blowout fracture Patients, male 5 cases (5 eyes), female 5 cases (5 eyes).3D model and surgical implant model was successfully designed and printed. All male group and female group orbital blowout orbital fracture 3D data model and print CT measurement is consistent, there were no significant differences (P0.05). By the senior surgeon in the operation room surgery of orbital simulation environment to the resident demonstration of orbital fracture surgical repair operation, 3D printing orbital blowout fracture model can be successfully used to simulate the operation and demonstration of 3D printing. Conclusion orbital blowout fracture model can restore the true orbital injury and orbital anatomic details, provide the design of stereoscopic preoperative model for physicians to understand the scope of orbital blowout fracture and surgical teaching has positive significance to simulation.
