Description of methods used for collection/generation of data: 3D- ultrasound volumes were obtained from the fetal face at 28-31 weeks gestation, with General Electric Voluson E8 system with a RAB 4-8 3D transducer (GE Medical Systems, Austria) 2. Methods for processing the data: Volumes were analysed by multiplanar imaging using 4D View software, version 10.5 (GE Medical Systems, Austria), to generate the measurements in the dataset(distances in mm, volumes in mm3 and angles in degrees). 3. Instrument- or software-specific information needed to interpret the data: Statistica Version 13 (Dell Software, Dell Inc. USA) 4. Standards and calibration information, if appropriate: N/A 5. Environmental/experimental conditions: Hospital setting for the ultrasound examinations, offline assessment of the volumes 6. Describe any quality-assurance procedures performed on the data: Measurements were obtained from multiple volumes per case, by two independent observers 7.
