HP:0100846 HP:0000312 Zygomatic flattening The malar process is the most medial and superior portion of the bony midface, articulating with the maxilla and temporal and sphenoid bones, contiguous with the lateral boundary of the nasal bridge. The term malar hypoplasia is no longer preferred because surface examination cannot distinguish hypoplasia from hypotrophy.
