摘　　要：目的利用多层螺旋CT（multi—slice CT，MSCT）量化义眼台大小，指导义眼台植入眼窝成形术，以改善术后义眼外观，减少手术并发症。方法利用MSCT测量眼眶及眼球径线，对32例患者植入的义眼术前进行量化和塑型。随访3～30月，观察术后动态和静态外观并评价其外观效果。结果所治32例患者中25例经3～30月随访取得较理想的外观整复效果，静态外观及义眼台活动度优良率均达到90％以上。结论利用MSCT获取眼眶及眼球的三维径线，依此量化义眼台的大小并指导义眼台植入是可行的。此技术将以往完全凭主观感觉和经验完成的手术精确量化，使手术变得更加规范易于操作，改善了术后义眼的外观整复效果，减少了术后并发症的发生。Objective To quantify hydroxyapatite size for plastic operation of socket of eyeball by MSCT technique in order to improve the postoperative appearance of artificial globe and decrease complications. Methods 3-dimensional diameter of patient＇ s orbit and eyeball were measured by MSCT. According to the 3-dimensional diameter, hydroxyapatites of 32 patients were quantified and moulded before operation. Postoperative follow-up for 3 to 30 months, static and dynamic appearances of artificial globe were observed and evaluated. Results Postoperatively,25 of 32 cases, who were followed up for 3 to 30 months,achieved good cosmetic results in the long term, meanwhile, static and dynamic appearances of artificial globe were satisfying. Conclusion According to the 3-dimensional diameters of patient＇ s orbit and eyeball, it is practicable and useful for hydroxyapatite implantation operation. The new technique which can precisely quantify the artificial globe made of hydroxyapatites is different from the old one which completely depends on operator＇s subjective sensation or clinical experience and can improve the postoperative appearance of artificial globe and decrease complications.
