Objective The aim of this research was to compare the fetal frontomaxillary facial (FMF) angle between normal and trisomy 21 fetuses at 11+0–13+6 weeks gestation in a Chinese population. Methods A prospective observational study was performed that included 640 euploid and 45 trisomy 21 singleton pregnancies undergoing first trimester ultrasound screening between 11 and 13+6 weeks of gestation. The FMF angle was measured in the midsagittal plane using the standard technique. Results The fetal mean FMF angle decreased with the increasing crown-rump length (CRL) from 88.6°at a CRL of 45 mm to 78.5° at a CRL of 84 mm (FMF angle = 100.212 − 0.258 × CRL, R2 = 0.222, p |
