2、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0.07~7.50am。术前两侧眼眶容积差值的平均值为(3.06~1.96)cm,术后差值减少到(O.93~1.O0)cm。,术前术后眼眶容积存在显著差异(P3、键词】颧眶骨折;眼眶容积;眼球内陷【中图分类号】R782.4[文献标识码】A【文章编号】1005.4979(2008)06.0405.04Computer·assistedVolumeMeasurementintheSurgicalCorrectionofOrbitozygomaticInjuriesWANGYu—xinl,TANGYou—shenSHIlun2,XUBinf1.DepartmentofOralandMaxillofacialSurgery,NanjingHospitalofStomatology,NanjingUn4、iversity,Nanjing210008,JiangSuProvince;2.DepartmentofOrdandMaxillofacialSurgery,ShanghaiNinthHospital,ShanghaiJiaotongUniversity,ShanghaiInstituteforStomatologicalResearch,Shanghai200011,China)[Abstract】Objective:Tocalibratetheorbitalvolumevariationsoforbitozygomaticfr5、acturepatientsinordertogetthecriticalvalueforprospectiveevaluatetheincidenceofpostoperativeenophthalmos.Methods:20patientswiththeorbitozygomaticfractureswerescannedbyMultiplySpiralCTpreoperativelyandpostoperatively.OrbitalvolumewasmeasuredbytheSimplantanalyticsoftwarea6、ndcomparedstatistically.Results:Preoperatively,orbitalvolumeenlargedinallpatients.witharangeof0.07-7.50cmcomparedwiththeoppositeintactorbit.withameanof3.51am±3.05.Butthisdecreasedto0.93am±1.O0followingoperation.Significantdifferencesinorbitalvolumesexistedbeforeandafte7、roperation<0.01).12patientsshowedclinicalenophthalmosafteroperation.Theirpreoperativeorbitalvolumewas4.60cm1.27.Conclusions:ThemeasurementoforbitalvolumecanhelpoperatortomakeoperationplanandrestoreoriginalOrbitalvolume.【Keywords】orbitozygomaticfracture;orbitalvolume;en8、ophthalmos眼眶容积增大是颧眶骨折后出现眼球内陷的变化情况及术后仍然可能出现眼球内陷的眼眶容积主要原因。近年来随着多排螺旋CT(MSCT)和计算的临界值。机辅助软件的应用,使得准确测量眼眶容积成为可1资料与方法能。在本研究中,
