摘要目的 探讨羟基磷灰石义眼台Ⅱ期植入术矫正眼窝重度内陷效果.方法 对26例(26眼)眼球摘除或眼内容摘除术后半年至38年采用羟基磷灰石义眼台Ⅱ期眶内植入.结果 眼窝重度内陷矫正术后外观良好.义眼活动度好,双眼相似,真假难辨.术后随访3～5年无排斥反应发生,未发现义眼台移位、脱出或眶内感染者.结论 Ⅱ期眶内植入义眼台矫正眼窝重度内陷要根据眶内容积大小和结膜囊腔大小选择术式和合适的义眼台,并需要用异体巩膜固定在4条直肌附着处覆盖于义眼台表面,可以增加义眼活动度,并可防止义眼台排出.

abstractsObjective To investigate the efficacy of secondary implantation of hydroxyapatite orbital implant for severe retraction of eye socket.Methods Twenty-six eyes of twenty-six cases,half an year to thirty-eight years after enucleation or evisceration,were treated with secondary hydroxyapatite orbital implantation.Results After operation of secondary implantation of hydroxyapatite orbital implant,orbital motion works well.The "eyes" feature of the two sides was similar,it was difficult to distinguish true and false.There was no occurrence of rejection,any orbital translocation,prolapse or intraorbita[infection in postoperative follow-up of three years to five years.Conclusion Suitable size selection of hydroxyapatite implants according to the orbital volume size and conjunctival sac cavity size in secondary operation,and the need for homologous sclera fixation in four rectus attachment,which made the sclera covered on the orbital surface,can increase the orbital motion,and can prevent the possibility of orbital discharge.
