VP15.01: Three‐dimensional evaluation of lip and palate at 12–14 weeks: a novel approach for evaluation of lip, palate and vomer bone

Adding three-dimensional (3D) image at NT section will make it easy to define normality of the face and palatine region. 1242 patients included with CRL between 65 to 84 mms. 3D image of fetal face in NT section was obtained. Multiplanar imaging with coronal section and midsagittal section side by side and coronal and axial sections side by side at 6 different levels following sections evaluated: 1. Lips; 2. PMT view; 3. At middle of palate for palatine shelves; 4. At 2/3 of palate-PPMT view which shows both palatine shelves and the vomer bone; 5. End of the palate to see PPMT and both palatine shelves; 6. End of vomer bone for PPMT, pterygoid processes and horisontal plate of the palatine bone. In coronal section. 3 dots representing the vomer bone as apex and right and left palatine processes as 2 dots at base s termed as PPMT (Prashant's Posterior Maxillary Triangle). Midsagittal section was obtained in 98%. 94% success in obtain 3D image of face. Midsagittal section was used to evaluate superimposed line sign and Maxillary gap sign, evaluation of lips and nostril - 100%, primary palate in 97%, mid palate in 98% and posterior palate in 98%, axial section of palate in 94%. PPMT was possible in 94% from 3D to look for both palatine shelves and suture line. Adding one 3D at NT section improves palate evaluation. PPMT in reconstructed coronal section helps us in looking for primary palate, palatine shelves and vomer bone.
