摘要
目的总结三平面正交法及特殊切面法在胎儿唇腭裂诊断的临床应用情况。方法对产前应用三平面正交法及特殊切面法检出的110例唇腭裂胎儿超声声像图特征及产后随访结果进行分析。结果 110例唇腭裂胎儿中,仅获得三平面正交法切面图像的胎儿36例(32.7%,36/110),获得三平面正交法切面及特殊切面图像的胎儿74例(67.3%,74/110)。产前超声显示鼻唇冠状切面110例(100%,110/100);显示正中矢状切面84例(76.4%,84/110);显示上牙槽横切面96例(87.3%,96/110);显示经旁正中矢状切面28例(25.5%,28/110);显示经梨状孔切面47例(42.7%,47/110);显示经下颌或下唇或颌下三角切面45例(40.0%,45/110);显示经面颊斜横切面16例(14.5%,16/110)。经三平面正交法或三平面正交法加特殊切面法明确诊断胎儿唇腭裂104例(94.5%,104/110)。受胎儿体位或羊水过少影响,6例(5.5%,6/110)胎儿唇/腭裂产前未明确诊断。结论产前应用三平面正交法及特殊切面法能有效、明确诊断胎儿唇腭裂,且有助于提高胎儿唇腭裂产前超声诊断准确性。
Objective To study the clinical significance of the method of three perpendicular planes plus special planes in diagnosing fetal cleft lip /palate by prenatal ultrasound .Methods The approach of three perpendicular planes and special planes were used in diagnosing 110 cases of cleft lip/palate.The sonogram features in each section were analyzed and the outcomes were recorded during follow-up.Results On prenatal ultrsound ,110 cases were examined with three perpendicular planes method .The coronary section could be displayed at 100%cases (110 cases), sagittal section 76.4%cases (84 cases),transverse section 96.4%cases (106 cases) and parasagittal section 25.5%cases (28 cases).With special planes method,74 cases were examined .The section through pyriform aperture could be displayed in 47 cases,in 45 cases on the section through the lower lip/lower jaw/submandibular triangle ,and in 16 cases on the section through the cheek.Combining the three perpendicular planes and special planes methods ,94.5%(104/110) cases could be diagnosed definitely.Six cases (5.5%,6/110) were missed because of fetal position or oligoamnios . Conclusions The method of three perpendicular planes plus special planes is effective in prenatal ultrasound diagnosing cleft lip/palate,which is of great help in improving prenatal diagnostic accuracy of fetal cleft lip/palate.
