羟基磷灰石义眼台Ⅱ期植入术

Secondary implantation of hydroxyapatite prosthesis

目的回顾和分析羟基磷灰石(HA)义眼台Ⅱ期植入术临床应用。方法采用不同手术方式对眼球摘除术后Ⅱ期义眼台植入10例,和眼内容剜除术后Ⅱ期义眼台植入8例。结果18例中成功植入18例,随诊6月～30月,均无发生义眼台暴露、感染、移位和义眼片固定。结论HA是一种较为理想的眼窝重建眶内植入材料,利用自体或异体巩膜多层覆盖HA义眼台眶内Ⅱ期植入,可以明显改善眼球摘除术后和眼内容剜除术后眼窝凹陷畸形和结膜囊狭窄等并发症。该方法安全简便,是眼眶美容术中一种理想方法,值得在基层医院推广。

Objective Retrospectively review and analyze the clinical applieation of secondary implantation of hydroxyapatite prosthesis. Methods The 10 eases after enucleation of eyeball and the 8 eases after evisceration of orbit had been received different operation program during secondary implant surgery. Results The 18 cases were found to be successful after following up for 5-18 months, none of these eases had been exposnre, infeetion, aversion and fixation. Conclusions HA is a good implant material of reconstruction of the socket. Secondary implantation with autogenous or heterogeneous multilayer sclera covering HA can obviously diminish complication of funnel socket and conjunctival stenotic after enucleation of eyeball and evisceration of orbit.With good and safe and simple program in orbit cosmesis,it can be widely used at basic-level hospital.
