The 2D axial transverse views of the fetal face: A new technique to visualize the fetal hard palate; methodology description and feasibility
Archive ouverte
International audience. OBJECTIVES:The objectives of this study were to describe the methodology and to assess the feasibility of a simple 2D ultrasound technique to visualize the fetal hard palate (FHP) using a strict axial transverse view (ATV).METHODS:Prospective cohort of 100 singleton pregnancies, screened routinely during second trimester scans. Three operators imaged the FHP through a strict 2D ATV according to a simple methodology. An expert sonographer reviewed all images, and palate normality was confirmed at birth. Univariate and multivariate analysis of factors modifying the ability to assess the palate were performed.RESULTS:Feasibility of imaging the FHP was obtained in 95% of cases with no difference between the operators (P = .7). The palate was visualized directly without fetal mobilization in 46%. An earlier gestational age at scanning, a prolonged duration of the scan, fetal back positioned anteriorly, fetal head flexed, a smaller amniotic pocket, and an unmoving fetal limb significantly reduced the feasibility. All failed attempts were in fetuses with their back located in anterior and in those with a deflexed head. Multivariate analysis did not converge because of the collinearity of most parameters.CONCLUSIONS:The ATV is an easy, simple, and accessible 2D method to visualize the FHP with no additional time.
