钛网数字化多点成形技术在颅骨缺损修补中的应用

目的：选择性能优良且安全的颅骨修补材料，探讨数字化多点成形技术在颅骨修补中的临床应用价值。 方法：颅骨缺损患者161例，采用钛网数字化多点成形技术进行颅骨修补43例，传统钛网人工塑形修补19例，骨水泥塑形修补99例；对比不同颅骨修补术的塑形工作量、手术时间、术后患者对塑形的满意度及术后并发症。结果：钛网数字化多点成形颅骨修补术平均手术时间［（30±6）min］，与骨水泥组［（70 ±18）min］和传统钛网人工塑形组［（50±11）min］比较明显缩短（P<0.01）；平均术中塑形工作量［（5±1）min］少于骨水泥组［（30±5）min］和传统钛网人工塑形组［（20±3）min］（P<0.05）；塑形满意度（100％）优于骨水泥组（91％）和传统钛网人工塑形组（95％）（P<0.05）。结论：钛网的性能明显优于骨水泥，钛网数字化多点成形技术修复颅骨缺损效果优于传统钛网人工塑形技术。

Application of shaping titanium mesh by multi-point forming technique in skull repairing

Objective To select materials with high quality and safety and evaluate the clinical value of multi-point forming technique in skull repairing. Methods 161 patients suffered from skull defect had been cured in our hospital, within them 43 patients were treated with multi-point forming technique in titanium mesh shaping, 19 patients with traditional handwork shaping, 99 patients with bone-like concrete (acrylate). The following aspects were analyzed and compared: neurosurgeons' shaping workload before operations, operative time, approving scale on shaping and complications after operation. Results Repairing skull by titanium mesh with the technique of multipoint shaping significantly shortened the average operative time to (30 ±6) min, compared with acrylate group (70±18 min) and titanium mesh traditional handwork shaping group (50±11 min) (P<0. 01); and decreased the neurosurgeons' working intensity of shaping time to (5±1 min), compared with acrylate group (30±5 min) and traditional handwork shaping group (20±3 min) (P<0. 05); and improved the patients' approving scale to 100%, compared with acrylate group (91%) and traditional handwork shaping group (95%) (P<0. 05). Conclusion The quality of titanium mesh is obviously better than acrylate, the effect of repairing skull with multi-point forming technique is superior to handwork shaping.
