“…We acknowledge that when a 2D image is not obtained, a 3D image might also be difficult to obtain. However, several authors reported that trained or specialized sonographers have an increased ability to diagnose cleft lips and their severity using 3DUS and need significantly shorter time periods to interpret findings [10,11,12,13,14,15,16,17,18]. Despite these benefits, the question of whether or not inexperienced sonographers can obtain similar results compared with experienced operators has never been studied.…”

Introduction: A standardized three-dimensional ultrasonographic (3DUS) protocol isdescribed that allows fetal face reconstruction. Ability to identify cleft lip with 3DUS using this protocol was assessed by operators with minimal 3DUS experience. Material and Methods: 260 stored volumes of fetal face were analyzed using a standardized protocol by operators with different levels of competence in 3DUS. The outcomes studied were: (1) the performance of post-processing 3D face volumes for the detection of facial clefts; (2) the ability of a resident with minimal 3DUS experience to reconstruct the acquired facial volumes, and (3) the time needed to reconstruct each plane to allow proper diagnosis of a cleft. Results: The three orthogonal planes of the fetal face (axial, sagittal and coronal) were adequately reconstructed with similar performance when acquired by a maternal-fetal medicine specialist or by residents with minimal experience (72 vs. 76%, p = 0.629). The learning curve for manipulation of 3DUS volumes of the fetal face corresponds to 30 cases and is independent of the operator's level of experience. Discussion: The learning curve for the standardized protocol we describe is short, even for inexperienced sonographers. This technique might decrease the length of anatomy ultrasounds and improve the ability to visualize fetal face anomalies.

“…The most common difficulties in 2D US scanning are related to visualization rates of the fetal face, mandible, lip, palate, tooth germs, distal part of the extremities, fingers and toes. [7][8][9][10] Depiction rate of these structures are significantly higher with 3D US (Table 1). 2,3,4,9 The data presented in Table 1 indicate that 3D US examination should be performed whenever 2D US is incapable to visualize these structures.…”

“…Due to their affection in malformation syndromes and chromosomal abnormalitie, regions of special interest are fetal maxilla, mandible arch, ear and nose. Ulm et al reported better visualization rate of tooth germs with 3D US than 2D US (31% vs 8.8%) 9 Merz et al studied 125 fetuses to examine the effect of 3D US imaging on evaluation of the axis of facial profile. 10 They found that in 30.4% of the results, the profile section of 2D US facial profiles had a bias of 3-20º compared with an optimal mid-sagittal section obtained by 3D US.…”

Three-dimensional, multiplanar sonography, using a volume data set acquired with a 3D probe, has revolutionized ultrasonographic imaging and takes sonographers to a new perception of the fetus in 3 dimensions. Real time scanning, until the late nineties only possible in B-mode, can now be performed in 3D with up to 40 frames/sec. Fetal neurology emerged as a new perinatal research field with the 4D visualization of fetal behavior. Doppler ultrasound, diversified and refined from continuous wave and pulsed Doppler to Color – and Power Doppler, when added to 3D sonography, creates fascinating options of noninvasive fetal vascular mapping (sonoangiography) and vascular assessment of placenta. The diagnostic and demonstrative potential of an acquired 3D volume data set can be maxed with the help of postprocessing and rendering software. After storage, the evaluation of fetal 3D data sets can happen without the patient, with the option of specialist consultation, using telemedicine. In the article, the new 3D “modes” like surface rendering, maximum mode, 3D Color and Power Doppler, STIC, volume rendering, and glass body rendering, are described and illustrated in their display of normal fetal anatomy.

Abstract:The evaluation of the fetal face is an important part of every ultrasound examination since detailed facial examination can provide many information alerting the examiner about possible associated anomalies. Face and the brain have the same embryonic origin. By using 2 and 3D ultrasound techniques, it is possible to obtain clear images of different fetal face defects. Incorporation of the 4D ultrasonography made it possible to examine fetal behavior including fetal face movements. In that way using the ultrasound in the examination of the fetal face provides many new information not just about the morphology but also about neurological development and function of the fetal face.
