Abnormal midface morphology (HP:0000309)help
Term ID: 309
Name: Abnormal midface morphology
Synonym: Abnormal morphology of the midface; Abnormality of the midface; Anomaly of the midface; Deformity of the midface; Malformation of the midface
Definition: An anomaly of the midface, which is a region and not an anatomical term. It extends, superiorly, from the inferior orbital margin to, inferiorly, the level of nasal base. It is formed by the maxilla (upper jaw) and zygoma and cheeks and malar region. Traditionally, the nose and premaxilla are not included in the midface.
