摘要
目的探讨计算机辅助设计定制化植入体,对复杂眶周畸形患者治疗的准确性和安全性。方法本文回顾了2009年1月至2012年12月,于我科接受计算机辅助设计定制化植入体治疗的眶周复杂畸形患者共106例,将患者术后6月CT扫描重建影像与术前计算机模拟设计行表面几何学差异分析,判断植入体与术前设计间的差异,并统计患者并发症的发生情况。结果 106例患者中,采集6个月后随访CT共105例,植入体形态平均误差(1.32±1.64)mm,85.72%的患者误差小于2 mm。除1例患者由于反复的额窦感染,在术后2个月取出植入体,其余患者均未发生严重的并发症。结论计算机辅助定制化植入体,治疗眶周复杂畸形高效、准确、安全,可作为复杂眶周畸形临床治疗的推荐方案之一。
Objective To investigate the efficiency and safety of computer assistant designed implants （CADI） in the treatment of complex orbital abnormalities. Methods A retrospective study was applied on 106 cases suffered from complex orbital deformity and treated with CADI during Jan. 2009 to Dec. 2012. The 6 months ’ postoperative CT image was compared to the pre-operative design. The surface geometric deviation was analyzed to evaluate the accuracy of CADI in orbital reconstruction. And the complications were documented. Results Among 106 cases, the CT images of 105 cases were obtained. The average deviation of the 105 cases was （1.32 ±1.64） mm. In 85.72%cases, the deviation was less than 2 mm. Only in one case the implant was taken out due to severe frontal sinus infection. No other serious complications were observed. Conclusion Computer assistant designed implant is an efficient, accurate and safe solution to complex orbital deformities. It might be one of the first choices in the treatment of complex orbital deformities.
