Abstract

Objectives

Craniofacial deformities have a high psychosocial impact. The aim of this paper is to improve obstetric ultrasonography and prenatal detection of facial anomalies by providing a new fetal dental panorama.

Material and methods

The present study describes a new modality to visualize the fetal tooth germs and an easy step-by-step diagnostic approach. Image acquisition was performed between 23 and 32 weeks of gestation using a Voluson E10 GE ultrasound machine with an RM6C transducer (GE Medical Systems, Zipf, Austria). Reconstruction was performed using Omniview from the axial image. Volume contrast imaging (VCI) was used with a thickness of 20 mm, and a render mode that combined “Rx mode” and “surface texture.”

Results

The resulting imaging allows a more precise visualization of the fetal dental arch and can be obtained between 14 and 28 weeks of gestation. The presence of dental anomalies can be a clue for the diagnosis of various congenital defects, in particular conditions with a shortage of other physical abnormalities, such as ectodermal dysplasia and Binder syndrome.

Conclusions

The creation of a precise fetal dental panorama allows an improved detection of facial deformities.

Clinical relevance

With the current paper, we want to increase prenatal diagnostics facial anomalies, and help to establish a tailored multidisciplinary treatment plan. This paper should be of interest to readers who are currently treating patients with craniofacial malformations and readers who are performing diagnostic prenatal sonography.
