Abstract:
Objective To review the prenatal ultrasound features and clinical value of fetal micrognathia.Methods All 13 500 cases were scanned for fetal faces with routine transverse,coronal and sagittal planes during prenatal ultrasonography.Results Thirteen cases with micrognathia were detected by prenatal ultrasonography.Midsagittal and coronal scans of all fetuses with micrognathia demonstrated small mandible and receding chin and the lower lip reside posterior to the upper lip.All prenatal diagnosed fetuses micrognathia were confirmed by autopsy.Conclusions Prenatal ultrasonic diagnosis of fetal micrognathia relied on subjective evaluation of fetal profile on a midline sagittal and a coronal scan of fetal face.Micrognathia may be a clue or marker of chromosomal anomalies and syndrome.Prenatal detecting of micrognathia has important clinical value.
