Objective To investigate the clinical value of ultrasonography in the diagnosis of fetal small jaw deformity. Methods The echographic features of 11 cases of fetal micrognathia were retrospectively analyzed and the clinical results were followed up. Results 11 cases of mandibular malformation fetus were confirmed by induction or labor. 2 cases were solitary parviomal deformities; 9 cases were associated with other structural deformities and / or chromosomal abnormalities. Conclusion Ultrasonography is a reliable method for the diagnosis of small jaw deformity. Combined with visual inspection and measurement, it can improve diagnostic accuracy and has important clinical value.
