目的 观察两种义眼座在眼窝成形术的效果。方法 眼球摘除或眼内容物剜除术后置入硅海绵义眼座 10例 ,羟基磷灰石 (HA)义眼座 3 4例。均置入分离出的肌锥内 ,用双层异体或自体巩膜覆盖于义眼座前面 ,术后 6～ 8个月可行钻孔手术。结果 随访 1～ 6年 ,硅海绵组有 1例感染 ,3例外露脱出 ,3例眼窝仍轻度凹陷。HA组未出现感染、置入物脱出现象 ,2例手术后早期出现伤口裂开 ,修复后痊愈。结论 HA组织相容性好 ,术后并发症少 ,在恢复眼眶内的容积 ,改善眼外观和加强义眼的活动等方面都令人满意 ,是当今眼窝成形术中较好的人工填充材料 ,改良的眼窝成形术是一种值得选择的手术方法。
Objective To observe the effect of two kinds of prosthesis in orbital surgery. Methods 10 cases of silicone sponge orbital seat and 34 cases of hydroxyapatite (HA) eye seat were enrolled in this study. Are placed into the isolated muscle cones, with double or self-sclera covered in front of the patent eye seat, postoperative 6 to 8 months feasible drilling surgery. Results One to six years follow-up showed that there was one case of infection in the sponge group, three cases of prolapse and three cases of eye socket still slightly depressed. HA group did not appear infection, implant prolapse phenomenon, 2 cases of early postoperative wound rupture, recovered after healing. Conclusion HA tissue compatibility is good, less postoperative complications, in the recovery of the orbital volume, improve the appearance of the eye and enhance the activity of the eye so satisfactory, is now a good artificial eye socket orbital filling material, Improved orbital surgery is a worthy choice for surgical procedures.
