To determine the efficacy of using a scaffold of hydroxyapatite blocks within the maxillary sinus to treat patients with large orbital floor fractures and secondary vertical globe dystopia.
Case series of five patients. Hydroxyapatite blocks were stacked within the maxillary antrum to support the reconstructed orbital floor.
All patients had good results, though mild residual enophthalmos persisted in three patients. The orbital floor implants and globe positions remained stable during follow-up intervals ranging from 46 to 65 months. No adverse postoperative complications, such as sinusitis, developed.
Hydroxyapatite block scaffolding is a useful alternative to metallic floor implants and autologous bone grafts in the reconstruction of large traumatic orbital floor defects associated with vertical globe dystopia.
确定在上颌窦内使用羟基磷灰石块支架治疗伴有继发性垂直性眼球内陷的大型眶底骨折患者的疗效。
对5例患者进行病例系列研究。将羟基磷灰石块堆叠在上颌窦内以支撑重建的眶底。
所有患者效果良好，不过3例患者仍存在轻度残余眼球内陷。在46至65个月的随访期内，眶底植入物和眼球位置保持稳定。未出现术后不良并发症，如鼻窦炎。
在重建与垂直性眼球内陷相关的大型外伤性眶底缺损时，羟基磷灰石块支架是金属眶底植入物和自体骨移植的一种有用替代方法。
