摘　　要：目的探讨羟基磷灰石眼座植入后暴露的原因及处理方法。方法对1997—2011年来本院就诊的73例羟基磷灰石眼座暴露患者进行回顾性分析。结果眼座暴露的发生时间为术后3 d^13年,暴露发生在术后6个月内的71例。暴露直径为3~17 mm,轻度暴露(≤5 mm)29例,先随访3~6个月,其中无好转倾向的和中度暴露(6~10 mm)的27例行眼座暴露修补手术治疗,重度暴露(>10 mm)17例行眼座置换手术或摘除眼座。所有手术病例均未发生感染,除1例经两次修补手术外,其余手术病例均未再次暴露。结论眼座暴露主要由于眼座排异、手术及术后义眼片佩戴不当引起。其治疗可根据暴露分级不同而采取随访观察、眼座暴露修补、眼座置换或眼座取出等不同治疗方法。Objective To explore the causes and managements of exposure of orbital hydroxyapatite implants. Methods A retro- spective analysis of 73 cases with hydroxyapatite implant exposure in the period from 1997 to 2011 was conducted. Results The implant exposure occurred 3 clays to 13 years after implantation. The exposure of 71 cases occurred in 6 months postoperatively. The diameter of the exposure was 3 - 17 mm. The 29 cases with mild exposure （ ~〈5 ram） were follow-up for 3 - 6 months. The 27 cases with moderate exposure （6 - 10 mm） and the cases with mild exposure whose condition didn＇ t get better were performed a re- pair surgery. The 17 cases with severe exposure （ 〉 10 mm） were performed replacement or removal of the orbital implants. There were no infections. There was also no postoperative implant exposure in all the patients except one who needed to be performed a second repair surgery. Conclusion The reasons of hydroxyapatite implant exposure are mainly due to implant rejection, surgery method, and improper wearing of prosthetic. Different methods including follow-up, repairing surgery and orbital implant replace- ment or removal may be applied according to the sizes of exposure.
