异形羟基磷灰石义眼台的临床应用

目的:观察异形羟基磷灰石义眼台植入术并发症及手术效果,探讨异形义眼台的适应证及其临床应用价值。方法:设计不同体积的异形羟基磷灰石义眼台,治疗眼球萎缩、眼内容物摘除及眼球摘除术后患者共30例。对照组植入常规圆球形羟基磷灰石义眼台共30例。异形义眼台组与对照组间性别、年龄、眼部情况相似。手术后随访时间6mo以上,观察患者义眼台植入术后球结膜愈合时间、义眼台暴露、感染等并发症、义眼台活动度、位置以及与义眼片适合程度的差异。结果:异形羟基磷灰石义眼台组没有发生义眼台暴露、感染等严重并发症,球结膜愈合时间短,义眼台植入后前表面呈圆弧形,能与义眼片很好的吻合,义眼台活动度及位置均好于对照组。对照组有2例(7%)发生早期球结膜裂开的并发症,经过治疗后均愈合。结论:异形义眼台可以降低义眼台植入后引起的并发症,可以有效适应患者眼部病变的情况,获得良好的手术效果,适应证更广,安全性更好。

Study of the outcome of obform hydroxyapatite orbital implant surgery

AIM: To observe the outcome of obform hydroxyapatite orbital implant surgery, and to investigate the indication of this surgery and its clinical application. ·METHODS: Sixty patients (60 eyes) who had atrophia bulbi, evisceration or ophthalmectomy received hydroxya-patite orbital implant surgery for atrophia bulbi in this study. They were randomly divided into 2 groups: study group and control groups (30 eyes in each group). Various kinds of obform hydroxyapatite orbital implants were designed for the patients in the study group. Other 30 patients in the control group had round hydroxyapatite orbital implant implanted into orbital. The age, sex and disease of the patients in 2 groups were almost same. All patients were observed over 6 months, the postoperative complications, the motion range and position of the implants and the fitness to prosthesis were compared between two groups. ·RESULTS: There were no postoperative complications after obform hydroxyapatite orbital implant surgery. The motion range and position of the obform hydroxyapatite orbital implants in polyporate sclera shell were better than that of the control group’s. The obform hydroxyapatite orbital implant could fit to the prosthesis nicely. There were 2 patients (7%) in the control group developed break in conjunctiva, which healed after medicine or surgery treatment. ·CONCLUSION: The obform hydroxyapatite orbital im-plant can reduce the postoperative complications, it can be used to utilize the autogeneic sclera and works for better outcome of the surgery.
