自体巩膜帽覆盖法预防羟基磷灰石义眼座暴露的临床研究

Clinical observation of autogenous scleral cap in preventing exposure of hydroxyapatite orbital implants

目的探讨自体巩膜帽覆盖羟基磷灰石义眼座对预防术后眼座暴露的临床效果。方法对眼内容摘除术后采用自体单层巩膜帽（46例）或自体双层巩膜帽（83例）为加固物行Ⅰ或Ⅱ期羟基磷灰石义眼座植入术。结果所有病例随访6～36月，均无义眼座暴露发生。结论在行羟基磷灰石义眼座植入时，采用白体单层或双层巩膜帽为加固物，能阻止眼座的粗糙表面对前部眼球筋膜囊和球结膜持续的机械刺激，避免眼球筋膜囊和球结膜裂开，有效地预防义眼座暴露。

Objective To observe the effects of self-scleral cap in preventing exposure of hydroxyapatite orbital implants. Methods One hundred and twenty-nine evisceration eyes adopted orbital implants with heterogeneous sclera as one layer cap or two layer cap. Results The follow-up period ranged from 6 to 36 months. All patients had no exposure of hydroxyapatite. Conclusions Hydroxyapatite orbital implants with heterogeneous sclera as a wrapping can prevent the exposure of hydroxyapatite effecteively.
