产前超声诊断胎儿外耳畸形的价值探讨

Value of prenatal ultrasound in diagnosis of fetal external ear deformity

目的探讨超声诊断胎儿外耳畸形的声像图特征及临床应用价值。方法回顾分析我院13例胎儿外耳畸形的声像图资料,分析其漏误诊原因。结果产前超声筛查出7例胎儿外耳畸形,漏诊6例。13例外耳畸形中9例为单纯性的外耳畸形,4例合并多系统畸形;8例伴羊水过多。10例行染色体核型分析,诊断为21-三体2例,18-三体3例。结论胎儿外耳畸形有其特殊的声像图表现,产前超声检查胎儿外耳可为产前诊断胎儿畸形提供丰富的诊断信息。

Objective To explore the sonogram features and application value of ultrasound in the diagnosis of fetal external ear deformity. Methods Sonograms of 13 cases of fetal external ear deformity were analyzed retrospectively, and the missed diagnosis and misdiagnosis causes were analyzed. Results There were 7 cases of fetal external ear deformity examined by prenatal ultrasonography, and 6 cases were missed. While in 13 cases ,there were 9 cases were simple external ear deformity, and 4 cases were multi - system deformity. There were 8 cases with polyhydramnios. 10 cases were karyotype analyzed in chromosome, there were 2 cases of 21-Three, and 3 cases of 18-Three. Conclusion Fetal external ear deformity has its own particular sonogram appearance, and prenatal ultrasound can provide more information for the diagnosis of prenatal fetal anomaly.
