Examination of the secondary palate on stored 3D ultrasound volumes of the fetal face.
Ultrasound Obstet Gynecol. 2009 Apr; 33(4):407-11.UO

Abstract

OBJECTIVES

To examine the use of oblique planes from stored three-dimensional (3D) ultrasound volumes of the fetal face for viewing the secondary palate at various gestational ages.

METHODS

3D ultrasound volumes of the fetal face acquired with surface rendering at 15-35 weeks' gestation in 31 fetuses with confirmed normal secondary palates were reviewed. The secondary palate was viewed in three oblique planes targeted at the uvula: the oblique axial, the oblique sagittal and the reverse face view. The detection and appearance of the secondary palate, including the soft palate, with these views at various gestational ages were compared.

RESULTS

The various surfaces of the secondary palate could be viewed in all 31 fetuses in the oblique axial and the reverse face views, and in all except two fetuses in the oblique sagittal view. Both of these were < 19 weeks' gestation, at which age the uvula could not be identified clearly in this plane.

CONCLUSIONS

The oblique axial, the oblique sagittal and the reverse face view targeted at the uvula allow visualization of the various aspects of the fetal secondary palate on 3D ultrasound in the second and third trimesters of pregnancy. The uvula could be used as a landmark for viewing the soft palate, but was not always easily identifiable before 19 weeks' gestation.
