两种不同羟基磷灰石义眼台植入术的临床观察

目的：比较眼球摘除+义眼台植入+异体巩膜移植术与眼内容物摘除+义眼台巩膜壳内植入术两种手术方式，探讨异体巩膜作为羟基磷灰石义眼台覆盖材料的优点。

方法：临床观察60例60眼，眼球摘除+HA植入覆盖同种异体巩膜者为异体巩膜组30眼，眼内容物摘除+HA自体巩膜壳内植入为自体巩膜组30眼。两组在术后1，3d； 1wk； 1，6mo进行随诊，观察结膜伤口愈合情况以及有无HA眼台的暴露。

结果：异体巩膜组中有6眼结膜伤口裂开，1眼HA眼台暴露。自体巩膜组中有7眼结膜伤口裂开，5眼HA眼台暴露，2例义眼台暴露后取出。

结论：眼球摘除+义眼台植入+异体巩膜移植术用于临床有较多优越性，术后并发症少。

Clinical observation of two different kinds of hydroxyapatite orbital implantation surgeries

AIM: To evaluate the efficacy of two kinds of hydroxyapatite(HA)implantation surgeries.

METHODS: In this retrospective case series from April 2009 to January 2012, 60 patients 60 eyes were included and allocated for primary enucleation and either homologous sclera-wrapped HA orbital implant or autologous sclera-wrapped HA orbital implant under local anesthesia, in order to compare conveniently, the same number cases in either series was selected. The main outcome measures included socket examination, HA implant exposure.

RESULTS: Six eyes in the homologous group had the splits in conjunctiva; 1 eye had HA exposure. 7 eyes in the autologous group had the splits in conjunctiva; 5 eyes had HA exposure and 2 of them had HA out of the orbit finally.

CONCLUSION: Homologous sclera wrapping HA is a good way to perform orbital implant surgery.
