To describe the clinical outcomes of patients receiving a quasi-integrated porous polyethylene orbital implant following enucleation for retinoblastoma.
A retrospective review of all retinoblastoma patients who received the quasi-integrated porous polyethylene implant following enucleation during the 56-month period between October 2000 and May 2005 was conducted.
Ten patients were identified who received the quasi-integrated porous polyethylene implant as a buried, primary orbital implant. Approximately 6 weeks following implantation, a custom-fitted prosthesis was made by an impression technique to provide a "lock-and-key" fit with the orbital implant in the majority of patients. Follow-up ranged from 2 months to 78.5 months following surgery, with an average of 36 months. One case of implant exposure was noted, with no other significant complications. Good motility of the prosthesis was noted in all cases.
The quasi-integrated porous polyethylene orbital implant is safe to implant and provides good prosthetic motility without the need for pegs or screws. It was associated with an exposure rate similar to other commonly used implants following enucleation in retinoblastoma cases.
描述视网膜母细胞瘤眼球摘除术后接受准一体化多孔聚乙烯眼眶植入物患者的临床结局。
对2000年10月至2005年5月期间56个月内所有视网膜母细胞瘤患者眼球摘除术后接受准一体化多孔聚乙烯植入物的情况进行回顾性研究。
确定10例患者接受了准一体化多孔聚乙烯植入物作为埋藏式原发性眼眶植入物。植入后约6周，多数患者通过印模技术制作定制义眼，以与眼眶植入物实现“锁钥”适配。术后随访时间为2个月至78.5个月，平均36个月。记录到1例植入物暴露，无其他严重并发症。所有病例义眼活动良好。
准一体化多孔聚乙烯眼眶植入物植入安全，无需栓钉或螺钉即可提供良好的义眼活动度。在视网膜母细胞瘤病例中，其暴露率与眼球摘除术后其他常用植入物相似。
