Study on normal reference value of fetal facial profile markers during the first trimester of pregnancy.

ABSTRACT:

Background

To establish a normal reference value for fetal facial profile markers during the first trimester of pregnancy.

Methods

We collected the data of 800 pregnant women who were examined during early pregnancy. The range of values of inferior facial angle (IFA), frontal nasal-mental (FNM) angle, frontomaxillary facial (FMF) angle, mandibulomaxillary facial (MMF) angle, fetal profile line (FPL), and maxilla-nasion-mandible (MNM) angle in normal fetuses of 11-13⁺⁶ weeks was measured and correlated. For the 1,000 fetuses that were screened in the early pregnancy period (11-13⁺⁶ weeks), follow-up the normal fetus, observe and measure the above parameters to obtain the normal measurement range. These markers were measured through GE Voluson E8 ultrasou
