3D打印引导钛网在成年人颅骨缺损修补中的应用

目的探讨3D打印引导钛网修补成年人颅骨缺损的临床应用价值。 方法选取南通大学第二附属医院神经外科自2017年1月至2018年12月收治的需进行颅骨修补术患者39例,根据修补技术将患者分为2组,采用常规修补术的11例患者为对照组,基于3D打印技术进行钛网颅骨修补术的28例患者为试验组。比较2组患者术后相关临床资料。 结果试验组与对照组在性别、年龄及平均缺损面积比较差异均无统计学意义（P>0.05）。试验组修补时间为（95.18±8.51）min,较常规手术（125.45±6.58）min明显缩短,同时试验组钛钉固定数目为（9.39±1.42）个,较常规手术的（11.55±1.86）个明显减少,差异有统计学意义（P<0.05）。而术后2组患者并发症发生率差异无统计学意义（P>0.05）。 结论运用3D打印技术引导钛网进行精准塑形剪裁安全可行,能缩短修补时间,减少术后并发症及风险,可运用于临床颅骨修补术。

Accuracy of three-dimensional printing-guided titanium mesh in repairing adult skull defects

ObjectiveTo explore the clinical value of three-dimensional (3D) printing-guided titanium mesh in repairing adult skull defects. MethodsThirty-nine patients who needed cranioplasty in Department of Neurosurgery, the Second Affiliated Hospital of Nantong University from January 2017 to December 2018 were selected. The patients were divided into two groups according to the repair technology. Eleven patients who underwent routine cranioplasty were the control group, and 28 patients who underwent titanium mesh cranioplasty based on 3D printing technology were the experimental group. The clinical data of the two groups were compared statistically. ResultsThere was no statistical difference in sex, age and average defect area between the experimental group and the control group (P>0.05). The repair time of the experimental group was (95.18±8.51) min, which was shorter than that of the conventional operation (125.45±6.58) min; and the fixed number of titanium nails in the experimental group was (9.39±1.42), which was lower than that in the conventional operation group (11.55±1.86), the difference was statistically significant(P<0.05). There was no significant difference in the complications between the two groups (P>0.05). ConclusionIt is safe and feasible to use 3D printing technology to guide precise plastic cutting of titanium mesh, which can shorten the repair time, reduce the complications and risks after operation. It can be used in clinical cranioplasty.
