摘要
目的:通过测量颧眶骨折术前术后眼眶容积的变化,得出术后可能仍然出现眼球内陷的术前眼眶容积大小。方法:20例颧眶骨折患者在术前及行坚固内固定术后,分别做多排三维螺旋CT(MSCT)扫描,利用Simplant软件测量眼眶容积进行比较,并做统计学分析。结果:术前20例患者均存在眼眶容积的增大,与健侧眼眶容积相比增大范围为0.07～7.50cm3。术前两侧眼眶容积差值的平均值为(3.06±1.96)cm3,术后差值减少到(0.93±1.00)cm3,术前术后眼眶容积存在显著差异(P<0.01)。10例患者术后仍然存在不同程度的眼球内陷,其术前眼眶容积差值为(4.60±1.27)cm3。结论:眼眶容积测定有助于术者制定手术方案,恢复应有的眼眶容积。
Objective： To calibrate the orbital volume variations of orbitozygomatic fracture patients in order to get the critical value for prospective evaluate the incidence of postoperative enophthalmos. Methods： 20 patients with the orbitozygomatic fractures were scanned by Multiply Spiral CT preoperatively and postoperatively. Orbital volume was measured by the Simplant analytic software and compared statistically. Results： Preoperatively, orbital volume enlarged in all patients, with a range of 0.07-7.50cm^3 compared with the opposite intact orbit, with a mean of 3.51cm^3±3.05. But this decreased to 0.93cm^3＋1.00 following operation. Significant differences in orbital volumes existed before and after operation （P〈0.01）. 12 patients showed clinical enophthalmos after operation. Their preoperative orbital volume was 4.60cm^3±1.27. Conclusions： The measurement of orbital volume can help operator to make operation plan and restore original orbital volume.
