Locking reconstruction plates have led to significant improvement in osteosynthesis and graft anchorage in mandibular reconstruction following the free fibula osteocutaneous flap. Plate extrusion is the most common complication associated with mandibular reconstruction, occurring in approximately 20% to 48% of cases; often necessitating plate removal once the bone flap has united to the mandible. Radiation therapy is a known risk factor to the development of such a complication and it presents further challenges to the successful removal of the reconstruction plate. Several reports have been published regarding plate removal in the setting of orthopedics that describe the management of jammed or stripped locking screws, but few in the setting of mandibular reconstruction. In this case, we report the successful removal of an exposed titanium mandibular reconstruction plate from a 41-year-old woman 12 months after her initial reconstruction with a free fibula osteocutaneous flap and radiation therapy. The approach was selected because the chin and neck skin could not be expected to be raised for full plate exposure secondary to radiation-induced skin changes (thinning and friability). We also discuss the use of previously employed methods of plate removal in various settings as well as their inherent strengths and weaknesses.
锁定重建钢板已使游离腓骨骨皮瓣下颌骨重建的骨合成和移植物固定有了显著改善。钢板外露是下颌骨重建最常见的并发症,约20%至48%的病例会发生;一旦骨瓣与下颌骨愈合,通常需要取出钢板。放射治疗是发生这种并发症的已知风险因素,并且对成功取出重建钢板提出了进一步挑战。关于骨科领域钢板取出已有多篇报道,描述了卡紧或拧脱锁定螺钉的处理方法,但下颌骨重建方面的报道较少。在此病例中,我们报告了一名41岁女性在初次采用游离腓骨骨皮瓣重建并接受放射治疗12个月后,成功取出外露的钛质下颌骨重建钢板。选择该方法是因为由于放射引起的皮肤改变(变薄和脆弱),预计无法掀起颏部和颈部皮肤以充分暴露钢板。我们还讨论了在各种情况下先前采用的钢板取出方法及其固有的优缺点。
