目的探讨鼻后三角在11~14孕周超声诊断腭裂的应用价值。方法回顾性分析我院检出的11~14孕周腭裂畸形8例,总结早孕期腭裂的声像图表现。结果早孕期诊断8例腭裂,均显示鼻后三角下方连线中断或缺失,其中4例为完全腭裂,3例左侧腭裂,1例右侧腭裂,产前诊断病例均经引产后证实。结论鼻后三角的观察有助于在早孕期提示胎儿腭裂畸形。

Methods Retrospective analysis of 8 cases of cleft palate malformation in 11 ~ 14 weeks of gestation in our hospital, summarizing the sonographic manifestation of cleft palate in early pregnancy. Results Eight cases of cleft palate were diagnosed during the first trimester, all of them showed interrupted or missing connective tissue below the posterior rhizotomy.
