1、二维、三维超声联合应用诊断胎儿唇裂【摘要】　目的　探讨二维超声、三维超声诊断胎儿唇裂的价值。　方法　对我院门诊孕检的18~40周胎儿，常规二维超声观测胎儿鼻唇情况，然后应用三维超声实时动态面部成像。　结果　三维超声对18~24周胎儿唇裂成像清晰直观逼真，二维超声对18~24周胎儿唇裂，检查费时，检查者须有经验；三维超声对36~40周胎儿实时成像困难，二维超声则可通过非标准切面面部成像；三维超声及二维超声对24~36周胎儿均能有效成像。　结论　二维、三维超声均能对胎儿唇裂明确诊断。不同孕期二维超声与三维超声各有优势，

2、三维超声在孕早期诊断唇裂有明显优势，二维超声在孕晚期略显优势。【关键词】　二维超声；三维超声；胎儿唇裂；孕18~40周Combinationoftwo-dimensionalandthree-dimensionalultrasoundinthediagnosisoffetalcheiloschisisZHANGCai-hong,CHENJian,DONGLi-ke.DepartmentofUltrasound,TheCentralHospitalofXuchang,HenanProvince461000,China

8、三维超声诊断胎儿唇裂各有优势，现把自2005年1月至2007年10月我院的工作总结如下。一、一般资料门诊孕检妇女，年龄22~35岁，孕龄18~40周，孕检总人次4000例，共检出唇裂10例，10例均经引产或足月产证实，6例在本院引产，2例在外院引产，2例本院足月产。二、仪器及方法采用GE-730彩色多普勒超声诊断仪，探头频率3.5~5MHz，孕妇仰卧位常规二
