数字化外科在游离腓骨瓣修复下颌骨缺损中的应用

摘要

Objective To summarize the application of computer aided three - dimensional visualization technique in different kinds of mandibular detects reconstruction with vascularized free fibular flap. Methods Totally 21patients diagnosed of recurrent mandibular ameloblas-toma underwent the virtually operation by software with a thinslice CT scan,which determined shape and position of the free flap,and preopera-tive resin model and modules were designed and prefabricated. Then the titanium plates were bent precisely,and the surgical recon - struetion proceeded exactly as expected from the modeling process. Results All operations were achieved successfully. The extent of the lesion was co-incident with the preoperative CT results,and the vascularized free fibular flaps were harvested and implanted into the defect regions accurately. All patients obtained the excellent functional and cosmetic outcomes. Conclusion The procedure of operation was simplified and the time was shortned with reconstruction exactly using computer aided three dimensional visualization technique,and the clinical therapeutic efficacy of re-construction of mandibular defect with vascularized free fibular flaps was improved notably.%目的：总结在数字化外科技术指导下，应用游离腓骨瓣修复不同类型下颌骨缺损的临床效果。方法术前收集21例患者相关区域的 CT 资料，数字重建下颌骨三维立体图形，模拟病变切除，并利用镜像技术进行腓骨的分段成角塑性。通过快速打印技术获得头模，进行钛板预成型，指导手术完成。结果全部手术成功，病灶组织按计划准确切除，术中腓骨瓣制备准确，术后腓骨瓣全部成活，患者咬合关系良好，面容恢复理想。结论应用数字化外科技术可以简化手术过程，节省手术时间，精确修复，提高游离腓骨瓣修复颌骨缺损的治疗效果，是一种较为理想的颌面部手术辅助方法。
