目的 评价隧道式预置线羟基磷灰石 (hydroxyapatite ,HA)义眼台二期眶内植入术的疗效。方法 不用异体巩膜包裹HA ,只在HA上钻两条水平隧道 ,并穿预置线 ,植入眼眶肌锥内 ,并分别与 4条眼外肌的预置线结扎。共行 5 3例。结果 5 3例患者术后眼窝饱满或明显改善 ,义眼活动度水平 15°～ 2 5°,垂直转动 10°。无排斥、脱出发生 ,实现了与健眼同步运动。结论 隧道式预置线羟基磷灰石二期眶内植入术 ,安全、可靠 ,缩短手术时间 ,减少了因异体巩膜包裹HA而引起的免疫排斥反应 ,为二期眶内植入术开辟了一个新的手术途径
Objective To evaluate the efficacy of tunnel preoperatively hydroxyapatite (HA) phacoemulsification with orbital implantation. Methods Without allogeneic sclera wrapping HA, only two horizontal tunnels were drilled in the HA, and the preformed lines were implanted into the orbital cone. The ligaments were ligated with the presetting lines of 4 extraocular muscles respectively. A total of 53 cases. Results In 5 3 cases, the orbital was full or significantly improved, the degree of eye movement was 15 ° ~ 25 °, and the vertical rotation was 10 °. No rejection, prolapse occurred, with the eye movement to achieve synchronization. Conclusion The tunnel-type hydroxyapatite second-stage orbital implantation is safe and reliable, shortens the operation time and reduces the immune rejection caused by the sclera wrapping HA, which opens up the second-stage orbital implantation A new surgical approach
