摘要: 目的: 探讨多类型数字影像拟合及3D打印技术在治疗髁突肿瘤中的临床意义。方法: 基于患者螺旋CT数据,血管CTA数据,牙齿3D扫描数据,联合运用软件Mimics 21.0 (Materialise, Belgium)重建患者上下颌骨、面部软组织、髁突肿瘤及周围重要解剖结构,并运用牙齿3D扫描数据与螺旋CT上下颌骨牙齿数据拟合,运用血管及软组织数据与颌骨数据拟合,最终在同一空间坐标系下得到包含有精确牙齿信息、髁突肿瘤及周围血管的上下颌骨复合体三维模型。设计并制作3D打印颌板辅助手术。结果: 6例患者均顺利完成手术,创口均一期愈合,所有患者咬合关系恢复良好,术后术后复查CBCT示骨瘤完整切除,长期随访未见关节强直及复发征象。结论: 多类型数字影像拟合及3D打印颌板可以精确重建髁突肿瘤及周围血管等重要解剖结构,便于术前充分了解术区情况,同时设计个性化颌板辅助手术,为手术创造空间,减少术区周围组织的损伤,该方法: 可作为治疗髁突肿瘤患者的一种辅助手段运用。

Abstract: Objective: To investigate the clinical significance of multiple types of digital images matching and 3D printing technology in the treatment of condylar tumors. Methods: According to patient's spiral CT data, CTA data of blood vessels, 3D scanning data of teeth, the maxillary, mandible, soft tissue and condylar tumors with surrounding important anatomic structures were reconstructed using Mimics 21.0(Materialise, Belgium). Then, matching the 3D scanning of teeth with bones data from spiral CT, matching the soft tissue with bones. Finally, in the same coordinate system, the three-dimensional model of the maxillary and mandible complex with tooth information, condylar tumors and surrounding blood vessels were obtained. Designing and 3D printing splint was assisted operation. Results: All 6 patients were underwent the operation successfully with the wounds healed at the same time. The occlusal relationship of all patients were well. The postoperative CBCT showed that complete resection of tumors and no signs of recurrence were found in long term follow-up. Conclusion: Multi types digital image matching and 3D printing splint could accurately reconstruct the important anatomic structures such as condylar tumors and peripheral blood vessels, so as to fully understand the operation area before operation. At the same time, personalized 3D splint was designed to create space for operation and reduce the damage of surrounding tissues. This method could be used as an auxiliary way to treat patients with condylar tumors.
