目的:观察国产带线羟基磷灰石(HA)义眼座植入的临床效果.方法:Ⅰ期植入在摘除眼球时,四条直肌预置缝线。Ⅱ期植入先分离寻找四条直肌,作预置缝线,再选用合适型号的国产带线HA义眼座,直接植入眶内,共实施48例并随访观察6月-24月。结果:植入的义眼座性能稳定可靠,术后眼睑饱满,义眼活动度良好,未发现球体脱出等现象。4眼术后出现结膜裂开,义眼座暴露;1例出现轻度上睑下垂,经相应处理恢复正常。结论:直接植入国产带线的HA义眼座,手术简单,安全可靠,无包裹材料排斥反应和溶解等并发症,且价格便宜,来源丰富,无毒无抗原性,是目前较理想的眼眶充填物。
Objective: To observe the clinical effect of home-made hydroxyapatite (HA) implantation.Methods: Ⅰ-stage implant was used to pre-suture the rectus muscle of the four rectus muscles. In stage Ⅱ, four rectus muscles were separated and looked for preoperative sutures, and then the appropriate type of HA-made ocular prosthesis seat was placed in the orbital region. A total of 48 patients were followed up and observed from June to 24 months. Results: The implanted prosthetic base was stable and reliable. The postoperative eyelid was full and the activity of the eye was good. No spheroid prolapse was found. In 4 eyes, conjunctival rupture occurred and the eye socket was exposed. One case had mild ptosis and returned to normal after corresponding treatment. CONCLUSION: The direct implantation of homemade HA eye wire with HA is simple, safe and reliable, without complications such as rejection and dissolution of the wrapped material. It is cheap, rich in source, non-toxic and antigen-free and is the ideal orbit Filling.
