目的:探讨羟基磷灰石义眼台植入术后的暴露原因及处理。方法:对32例羟基磷灰石义眼台植入术后义眼台暴露的患者做回顾性分析结果,对暴露直径>3mm者行手术治疗;对暴露直径<3mm者,先行观察1mo,如仍无愈合,则全部给予手术治疗。结果:全部患者经再次手术经观察1a后,无再次暴露,取得满意的效果。结论:手术中注意手术技巧,合理选择义眼台可以有效地预防义眼台暴露。

AIM:To investigate the reasons of exposure after intraorbital implantation of hydroxyapatite(HA) and the methods of preventing exposure.METHODS:Thirty-two patients suffered from exposure after intraorbital implantation of hydroxyapatite were retrospectively studied.RESULTS:The causes of exposure after hydroxyapatite orbital implantation included inappropriate operative procedure in 17 cases,mismatching hydroxyapatite in 6 cases,incorrect postoperative management in 5 cases and infection in 4 cases.After secondary surgery,the result of 32 patients were satisfactory.CONCLUSION:Careful operating and appropriate hydr-oxyapatite could avoid hydroxyapatite orbital exposure effectively.
