摘　　要：目的：回顾１００ 例眼球摘除术后羟基磷灰石义眼座眼窝成形术的体会，旨在探讨该手术出现的问题及处理。方法：采用巩膜包裹羟基磷灰石球作为眼球摘除术后眼窝成形的充填物，其中自体巩膜包裹羟基磷灰石球一期植入者６１ 例，异体巩膜包裹羟基磷灰石球二期植入者３９ 例。结果：随访６ ～２４个月，除２ 例因故取出（ 其中１ 例因眶内感染） ，余均获满意的外观且义眼运动良好。其它问题还有结膜变薄３ 例；结膜延迟愈合７ 例；植入物略下移１ 例（ 因二期植入时，下直肌未找到） 。无植入物排除现象。结论：用羟基磷灰石义眼座充填适合于任何眼球摘除术后需要进行眶内植入的患者，无其它义眼座所常见的高排斥率及感染率。为进一步降低手术并发症，应注意选择手术适应证及避免手术操作疏忽。Experience with 100 consecutive cases of hydroxyapatite orbital implant was reviewed and the problems of the implants and their management investigated specifically.Hydroxyapatite spheres were implanted primarily into autosclera capsule in 61 cases.Secondary implantation was performed with heterosclera-encapsulated ones in 39 cases.All cases were followed up for 6～24 months.The external appearance and motility of all prosthesis was satisfactory except that 2 implants were enucleated (one case of presumed orbital infection).Other problems included conjunctival thinning in 3 cases,postponement of conjunctival healing in 7 cases and implant migration in 1 case.No cases of implant extrusion.The hydroxyapatite orbital implant is a well tolerated motility implant without high rate of extrusion and infection seen with other motility implant.We consider it is important to select surgical indications and avoid carelessness in manipulation for reducing their incidence.
