摘要
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 clinical comparative effect of two orbital implants in ocular socket plasty.Methods 10 cases were implanted with siliconsponge sphere implants,34 cases with hydroxyapatite (HA) artificial eye bases following eyeball enucleating or eye eviscerating. During the operation, a HA sphere was inserted into the muscle cone. Two layers of homologous or autologous sclera were placed over the anterior surface of the HA sphere. After six to eight months, drilling operation was performed. Results In 1～6 years of followup, of the cases with the siliconsponge,1 case had implant infection,3 cases had implant extrusion and 3 cases were seen as light enophthalmic socket. In hydroxyapatite implant group there was no inflammation or extrusion, 2 cases happened with wound dehiscence in the earlier stage after the operation, however, satisfied result was achieved after second repair.Conclusion Hydroxyapatite is naturallyoccurring material and is not treated as a foreign substance by the body .There have been few complications.It is advantageous in replacing the volume of the orbit .Satisfactory prosthetic motility and cosmetic appearance have been obtained. It is considered that at present hydroxyapatite implant is made of one of the best materials and this method of socket plasty is one of the best method for selection.
