羟基磷灰石义眼座植入Ⅰ期钻孔的初步效果

目的 评价羟基磷灰石义眼座植入Ⅰ期钻孔放置钛钉的疗效。方法 对31例眼球摘除患者行Ⅰ期或Ⅱ期羟基磷灰石义眼座植入同时行钻孔,钻入钛钉的螺纹套子,中间放置平头钉,3～7个月后剪开,更换为球头钉,定制义眼片。结果 随访3．0～11．0个月(平均6．9个月),所有患者对义眼外观及活动度满意,无义眼座暴露、继发感染、栓钉脱出、栓钉偏斜等并发症。结论 羟基磷灰石义眼座植入Ⅰ期钻孔手术效果好,无明显增加并发症的发生机会,是一种可供选择的手术方法。

Preliminary report on primary drilling procedure at the time of hydroxyapatite orbital implant

Objective To evaluate the clinical effect of the drilling and inserting a motility peg at the time of hydroxyapatite orbital implant. Methods After drilling and insertion of a titanium motility peg, a hydroxyapatite orbital implant was inserted in 31 consecutive patients. Of the 31 patients, 23 had been referred for primary enucleation and 8 for secondary implant surgery. The titanium threaded sleeve was driven into the hydroxyapatite after which the titanium flat headed peg was inserted into the sleeve before orbital implantation. The flat headed peg was replaced with a titanium motility/support peg 3 to 7 months later. Results Follow up ranged from 3.0 to 11.0 months (mean, 6.9 months). All patients were successfully fit with prostheses. Prosthetic motility was acceptable in each patient. 12 of 31 titanium flat headed pegs became spontaneously and partially exposed within 3 to 7 months. There were no cases of secondary infection, implant exposure or extrusion of the motility peg. Conclusion The hydroxyapatite orbital implant primary drilling procedure gives good cosmetic results with good motility of the artificial eye. It does not result in increased complications, and is an effective and efficient surgical option.
