摘　　要：目的 验证计算机辅助手术导航（computer-assisted navigation system,CANS）提高个性化预成钛网治疗眼眶骨折继发眼球内陷的治疗效果.方法 收集2006年9月至2013年10月北京大学口腔医学院·口腔医院口腔颌面创伤中心49例单侧眼眶骨折,分为两组：导航组（A组）25例,非导航组（B组）24例,采用个性化预成钛网重建眼眶矫治继发性眼球内陷.分别测量手术前后健患侧眼球突度、眼眶容积和钛网植入深度,并进行比较.结果 患侧眼球内陷改善度：A组（3.35±1.46） mm,B组（2.25±1.14） mm,两组差异有统计学意义（P＜0.05）;患侧眼眶容积恢复量：A组（5.94±2.20） ml,B组（4.21±2.18） ml,两组差异有统计学意义（P＜0.05）;钛网植入深度：A组（31.95±2.97） mm,B组（29.27±2.72） mm,两组差异有统计学意义（P＜0.05）.结论 导航引导下应用个性化预成钛网治疗眼眶骨折继发眼球内陷在重建眶壁形态、保护眶尖区结构等方面具有较大优势,效果更好.Objective To evaluate the efficiency of individually fabricated titanium mesh to correct enophthalmos following orbital fracture by using computer-assisted navigation system.Methods Forty-nine patients with unilateral orbital fracture were divided into navigation group （25 cases） and non-navigation group （24 cases）.All patients underwent orbital reconstruction to correct post-traumatic enophthalmos with individually fabricated titanium mesh.The bilateral global projection and the orbital volumn were measured preoperatively and postoperatively.The depth of titanium mesh was measured postoperatively.Results Statistical analysis demonstrated the global projection at the affected side increased by （3.35 ± 1.46） mm in navigation group and by （2.25 ± 1.14） mm in non-navigation group postoperatively,and there was a significant difference between the two groups （P＜0.05）.The orbital volumn at the affected side decreased by （5.94 ± 2.20） ml in navigation group and by （4.21 ± 2.18） ml in non-navigation group,and there was a significant difference between the two groups （P＜0.05）.The depth of titanium was （31.95±2.97） mm in navigation group and （29.27±2.72） mm in non-navigation group,and the values between the two groups differed significantly （P＜0.05）.Conclusions The use of computer-assisted navigation for the orbital wall reconstruction with individually fabricated titanium mesh can protect the optic nerve reliably and achieve satisfactory results.
