Lateral facial clefts are atypical with a low incidence in the facial cleft spectrum. With the development of ultrasonography (US) prenatal screening, such facial malformations can be detected and diagnosed prenatally rather than at birth. Although three-dimensional US (3DUS) can render the fetus' face via 3D reconstruction, the 3D images are displayed on two-dimensional screens without field depth, which impedes the understanding of untrained individuals. In contrast, a 3D-printed model of the fetus' face helps both parents and doctors develop a more comprehensive understanding of the facial malformation by creating more interactive aspects. Herein, we present an isolated lateral facial cleft case that was diagnosed via US combined with a 3D-printed model.
A 31-year-old G2P1 patient presented for routine prenatal screening at the 22nd wk of gestation. The coronal nostril-lip section of two-dimensional US (2DUS) demonstrated that the fetus' bilateral oral commissures were asymmetrical, and left oral commissure was abnormally wide. The left oblique-coronal section showed a cleft at the left oral commissure which extended to the left cheek. The results of 3DUS confirmed the cleft. Furthermore, we created a model of the fetal face using 3D printing technology, which clearly presented facial malformations. The fetus was diagnosed with a left lateral facial cleft, which was categorized as a No. 7 facial cleft according to the Tessier facial cleft classification. The parents terminated the pregnancy at the 24th wk of gestation after parental counseling.
In the diagnostic course of the current case, in addition to the traditional application of 2D and 3DUS, we created a 3D-printed model of the fetus, which enhanced diagnostic evidence, benefited the education of junior doctors, improved parental counseling, and had the potential to guide surgical planning.
Core Tip: In this study, we present a case with rare facial anomaly of isolated lateral facial cleft. In the prenatal diagnostic course, in addition to the traditional screening using two-dimensional and three-dimensional (3D) ultrasonography, we created a 3D-printed model of the fetus which enhanced diagnostic evidence, benefited the education of junior doctors, improved parental counseling, and had the potential to guide surgical planning.
