两种不同术式Ⅰ期羟基磷灰石义眼座植入术的临床研究

目的比较两种不同术式的Ⅰ期羟基磷灰石义眼座植入术的临床疗效。方法将99例有义眼座植入适应证患者分为A、B两组，A组行眼球摘除巩膜包裹法植入义眼座，B组行眼内容剜除巩膜覆盖法植入义眼座，术后观察两组患者配戴义眼后外观改善程度、术后并发症。结果两组患者外观改善程度差异无显著性，但A组结膜裂开发生率高于B组（Х^2=7.380，P〈0.01），义眼座暴露发生率也高于B组（Х^2=5.160，P〈0.05）。结论眼内容剜除巩膜覆盖法是一种较眼球摘除巩膜包裹法简单、安全、方便、疗效确切的义眼座植入手术，值得在临床推广应用。

Clinical study of two kinds of operation of enucleation associated with primary implantion hydroxyapatite prosthesis

Objective To compare the clinical effects of two types of surgery, for implanting a hydroxyapatite prosthesis in the orbit. Methods Ninety-nine patients who needed hydroxyapatite prosthesis implants were divided into groups A and B. The surgery for group A involved the use of sclera to cover the intraorbital hydroxyapatite prosthesis after enucleation, for the surgery in group B, sclera was wrapped around the intraorbital hydroxyapatite prosthesis after enucleation. The appearance of the patients was evaluated after the ocular prosthesis was implanted and complications from the two types of surgery were noted. Results There was no difference in appearance between the two groups. The rate of conjunctiva breakup and hydroxyapatite prosthesis exposure in group A was higher than that for group B. Conclusion The operation in which sclera is wrapped around the intraorbital hydroxyapatite prosthesis after enucleation is simple,safe, convenient and effective. It is worthwhile to disseminate information widely about this procedure.
