目的 评价羟基磷灰石 (hydroxyapatite,HA)义眼座植入后钻孔置钉手术的中、长期疗效 ,探讨HA义眼座钻孔置钉后各种并发症的发生原因及其防治方法。方法 对HA义眼座钻孔放置栓钉手术已 3年以上的 6 8例进行回顾性研究 ,总结手术前后的外观、义眼的活动度、结膜囊分泌物的情况及其他并发症。结果 随防 36～ 72个月 ,无继发感染 ,所有患者对其外观、活动度满意 ,6例发生栓钉脱出 ,31例出现分泌物明显增加 ,5例发生肉芽组织过度增生。结论 钻孔手术能明显改善患者外观 ,增加义眼活动度 ,并发症较轻 ,且易防治。对义眼座活动性较好、已血管化、结膜囊较大 ,并能配合局部麻醉手术者 ,应行钻孔置钉手术。
Objective To evaluate the long-term and long-term curative effect of hydroxyapatite (HA) phacoemulsification after drilling and placement of HA, and to explore the causes and prevention and treatment of various complication after hydroxyapatite HA implantation. Methods A retrospective study was performed on 68 cases of HA pedestal placement peg operation for more than 3 years. The appearance of the preoperative and postoperative eyes, the activity of the eyelid, the secretions of conjunctival sac and other complications were summarized retrospectively. Results With no anti-infection for 36-72 months, all patients were satisfied with their appearance and activity. There were 6 cases with peg excretion, 31 cases with excretion increased significantly and 5 cases with granulation tissue hyperplasia. Conclusion Drilling surgery can significantly improve the appearance of patients with increased activity of the eye, the lesser complications, and easy to control. On the eyelid mobility is better, has vascularization, conjunctival sac larger, and can cooperate with local anesthesia surgery, drilling operation should be set screw.
