The purpose of this study was to determine whether scanning of the fetal midface in the axial plane allows accurate characterization of facial clefts. During fetal anatomic survey, facial clefts were identified in six fetuses. The midface anatomy was evaluated with ultrasonography in the coronal and axial planes, and the clefts were characterized prospectively as unilateral or bilateral and as involving the lip alone or both the lip and the palate. The integrity of the upper lip was assessed in the coronal and axial planes. The continuity of the normal C-shaped curve of the tooth-bearing alveolar ridge and the anterior six tooth sockets was assessed in the axial plane. The prospective prenatal diagnosis was correlated with postnatal findings in all cases. The clefts where characterized prospectively as unilateral cleft lip (one case), unilateral cleft lip and cleft palate (four cases), and bilateral cleft lip and cleft palate (one case). The prenatal characterization was confirmed to be correct postnatally in all cases. Prenatal sonographic evaluation of the axial view of the tooth-bearing alveolar ridge of the maxilla allows accurate determination of whether a cleft is confined to the lip or involves both the lip and the palate.
本研究的目的是确定在轴向平面扫描胎儿中面部是否能准确表征面部裂隙。在胎儿解剖学检查期间，在6例胎儿中发现了面部裂隙。通过超声在冠状面和轴向平面评估中面部解剖结构，并前瞻性地将裂隙表征为单侧或双侧，以及仅累及唇部或同时累及唇部和腭部。在冠状面和轴向平面评估上唇的完整性。在轴向平面评估含牙牙槽嵴和前六个牙槽窝正常C形曲线的连续性。所有病例的前瞻性产前诊断均与产后结果相关。这些裂隙前瞻性地表征为单侧唇裂（1例）、单侧唇裂和腭裂（4例）以及双侧唇裂和腭裂（1例）。所有病例的产前表征在产后均被证实是正确的。产前超声对上颌含牙牙槽嵴轴向视图的评估能够准确确定裂隙是否仅局限于唇部或同时累及唇部和腭部。
