颧上颌骨复合体骨折后眶容积的测量及其临床意义

摘要/Abstract

摘要：

目的　应用三维重建技术和计算机软件辅助测量技术，精确测量颧上颌骨复合体骨折伴眼球内陷患者眶容积的改变量，为手术恢复眶容积及重建眼眶外形提供依据。方法　18例颧上颌骨复合体骨折伴眼球内陷的患者，分别行64排三维螺旋CT扫描，利用Simplant软件测量健侧与患侧眶容积并进行比较，并进行统计学分析。结果　18例患者患侧眶容积均存在不同程度增大，健侧与患侧眶容积差值为（1.83±0.75）cm3，双侧眶容积存在显著统计学差异(P=0.000)。男性健侧眶容积的平均值为（28.50±　1.15）cm3，女性为（23.57±1.31）cm3，不同性别患者健侧眶容积之间也存在统计学差异(P=0.000)。结论　颧上颌骨复合体骨折早期进行眶容积的测定有助于术者制定手术方案，准确恢复原有的眶容积，避免眼球内陷等并发症的发生。

Abstract:

Objective　To calibrate the variations of orbital volume of zygomaticomaxillary complex fracture patients, and get the accordance to recover the normal orbital volume and shape, based on three-dimensional reconstruction and computer software technique.　Methods　18 patients with the zygomaticomaxillary complex fractures and endophthalmos were scanned by multiple spiral CT, and then, the Simplant analytic software was used to calibrate and compare statistically the intact and traumatized orbital volume.　Results　Traumatized orbital volume significantly enlarged in all patients, with a mean volume of (1.83±0.75) cm3 compared with the opposite intact orbit (P=0.000). For the males, the intact orbit volume was about (28.50±1.15) cm3, which was significant different with that of the females (23.57±1.31) cm3 (P=0.000). Conclusions　The promptly measurement of orbital volume is helpful for making optimal operation plan, recovering accurately the original orbital volume, and avoiding the development of endophthalmos.
