The present study is to compare the effectiveness of iliac crest graft and medpor implant, for repairing traumatic orbital floor defects.
A total of 20 patients were included in the study. Autogenous iliac crest graft and medpor implant was used in 10 patients of the each group. Patients were evaluated for the presence or absence of diplopia, enophthalmos, infraorbital nerve paresthesia, and ocular motility disorders. Surgical indications for orbital exploration included entrapment of orbital tissues, large orbital defect (greater than 50% of the orbital floor or more than 8 mm), or orbital floor defects with involvement of other zygomaticofrontal complex fractures.
All patients were successfully treated by restoration of the orbital wall continuity. Follow-up was done at 1-12 weeks. One patient had postoperative infection. There was no graft extrusion.
Both the groups showed satisfactory results, but group II was better than group I, as there was no donor site morbidity. Porous polyethylene (Medpor) is a biocompatible and high-density polyethylene implant. It is well tolerated by surrounding tissue, and its porous structure is rapidly infiltrated by host tissue. It is a highly stable and somewhat flexible porous alloplast that has rapid tissue in growth into its pores.
本研究旨在比较髂嵴移植和Medpor植入物修复外伤性眶底缺损的有效性。
本研究共纳入20例患者。每组10例患者,分别采用自体髂嵴移植和Medpor植入物。对患者进行复视、眼球内陷、眶下神经感觉异常和眼球运动障碍的评估。眼眶探查的手术指征包括眼眶组织嵌顿、大的眼眶缺损(大于眶底的50%或超过8毫米)或伴有其他颧额复合体骨折的眶底缺损。
所有患者均通过恢复眶壁连续性成功治疗。随访1至12周。1例患者术后感染。无移植物挤出。
两组均显示出满意的结果,但第二组优于第一组,因为无供区并发症。多孔聚乙烯(Medpor)是一种生物相容性高密度聚乙烯植入物。它能被周围组织良好耐受,其多孔结构能迅速被宿主组织浸润。它是一种高度稳定且稍有柔韧性的多孔异体植入物,宿主组织能迅速长入其孔隙。
