唇腭裂是口腔颌面部最常见的先天性畸形。国人唇腭裂发病率约1‰。主要因胚胎发育的前10周内球状突、侧鼻突与上颌突融合不全所致。以往胎儿出生后才能确诊,现利用B超能在胎儿期诊断唇裂,且准确、迅速、无痛苦、可重复,国内目前报道尚少。1 材料和方法 1989年5月至1990年8月,我室用RT3600型B超诊断仪,3.5MHz线形探头,诊断了3例胎儿唇裂。操作要点:孕妇取仰卧位,涂耦合剂后,沿腹壁探查,达胎儿头部,向胎儿眼、鼻、口方向以与胎儿呈横断切面移动探头,鼻与口腔之间的较强回声弧形切面,即为上唇;或与胎儿呈矢状切面探得面部后,将探头旋转90°方向,呈横断切面上、下移动探
Cleft lip and palate is the most common oral and maxillofacial congenital malformations. The incidence of cleft lip and palate about 1 ‰. Mainly due to the first 10 weeks of embryonic development of globular processes, lateral nasal process and maxillary process caused by incomplete fusion. In the past the fetus was diagnosed after birth, is the use of B-ultrasound in the diagnosis of cleft lip during pregnancy, and accurate, rapid, painless, repeatable, the domestic report is still small. 1 Materials and Methods May 1989 to August 1990, I used RT3600 B-mode diagnostic apparatus, 3.5MHz linear probe, diagnosed 3 cases of fetal cleft lip. Operation points: Pregnant women to supine position, coated with couplant, along the abdominal wall exploration, up to the fetus head, to the fetal eye, nose, mouth direction and the fetus was transverse section of the probe, nasal and oral Echo between the strong echo Section, that is, the upper lip; or fetal sagittal section was probed face, the probe rotated 90 ° direction, was transverse section, the next move to explore
