Abstract：
The study aimed to evaluate and discuss the use of an innovative PSI made of porous hydroxyapatite, with interconnected porosity promoting osteointegration, called MyBone Custom® implant (MBCI), for maxillofacial bone reconstruction. A multicentric cohort of 13 patients underwent maxillofacial bone reconstruction surgery using MBCIs for various applications, from genioplasty to orbital floor reconstruction, including zygomatic and mandibular bone reconstruction, both for segmental defects and bone augmentation. The mean follow-up period was 9 months (1-22 months). No infections, displacements, or postoperative fractures were reported. Perioperative modifications of the MBCIs were possible when necessary. Additionally, surgeons reported significant time saved during surgery. For patients with postoperative CT scans, osteointegration signs were visible at the 6-month postoperative follow-up control, and continuous osteointegration was observed after 1 year. The advantages and disadvantages compared with current techniques used are discussed. MBCIs offer new bone reconstruction possibilities with long-term perspectives, while precluding the drawbacks of titanium and PEEK. The low level of postoperative complications associated with the high osteointegration potential of MBCIs paves the way to more extensive use of this new hydroxyapatite PSI in maxillofacial bone reconstruction.
摘要：
该研究旨在评估和讨论由多孔羟基磷灰石制成的创新PSI的使用，相互连接的孔隙促进骨整合，称为MyBoneCustom®植入物（MBCI），用于颌面部骨重建。使用MBCI进行各种应用的13例患者接受颌面骨重建手术的多中心队列，从生殖器成形术到眶底重建，包括颧骨和下颌骨重建，用于节段性缺陷和骨增强。随访时间1～22个月,平均9个月。没有感染,流离失所，或报告术后骨折。必要时可以对MBCI进行围手术期修改。此外,外科医生报告说，手术期间节省了大量时间。对于术后CT扫描的患者，在术后6个月随访控制时可见骨整合征象，1年后观察到连续骨整合。讨论了与当前使用的技术相比的优缺点。MBCI提供了新的骨重建的可能性与长期的观点，同时排除了钛和PEEK的缺点。与MBCIs的高骨整合潜力相关的低术后并发症水平为这种新的羟基磷灰石PSI在颌面部骨重建中的更广泛使用铺平了道路。
