二期活动义眼植入联合结膜囊成形术探讨

Clinical investigation of secondary implantation of movable orbital combined with conjunctival sac plasty

目的探讨二期HA义眼台植入联合结膜囊成形术手术效果。方法10例（10眼）因摘除眼球长期佩戴厚重义眼造成下穹窿浅及睑外翻，行二期HA义眼台植入联合下穹窿成形术。结果6例轻度下穹窿浅轻度外翻，行HA植入联合下穹窿深层埋线术；4例轻度下穹窿浅中度外翻，行行HA义眼台植入联合下穹窿深层埋线及下眼睑全层V型缩短术。随访2～12月手术效果良好。结论二期HA植入联合结膜囊成形术，术式简单，节省费用，术后效果良好。

Objective To investigate the effect of secondary orbital hydroxyapatite （HA） implant combined with conjunctival sac plasty. Methods Ten eyes of 10 patients were suffered from shallow lower fornix and ectropion that caused by long-period wearing of thick and heavy artificial eye. The secondary HA implantation combined with the reconstruction of lower fornix was conducted. Results For 6 patients with mild shallow lower fornix and mild extropion, HA implantation and lower fornix reconstruction with buried suture were operated ; For 4 patients with mild shallow lower fornix and moderate ectropion, the HA implantation, lower fornix reconstruction with buried suture, and V-type shortening of full-thickness lower eyelid were operated. The 2 - 12 month follow-up of these patients were good. Conclusion The clinical effect of secondary orbital hydroxyapatite（HA） implant combined with conjunctival sac plasty is good..
