Nasal bridge

Nasal bridge is the bony part of the nose, overlying the nasal bones, above the part in blue labeled "Cartilage of Septum".
The bridge is between the eyes, and just below them. The lower half of the nose is below the bridge.

The nasal bridge is the upper, bony part of the nose, which overlies the nasal bones.

Association with epicanthic folds

Low-rooted nasal bridges are closely associated with epicanthic folds. A lower nasal bridge is more likely to cause an epicanthic fold, and vice versa.[1]

Dysmorphology

A lower or higher than average nasal bridge can be a sign of various genetic disorders, such as fetal alcohol syndrome. A flat nasal bridge can be a sign of Down syndrome (Trisomy 21), Fragile X syndrome, 48,XXXY variant Klinefelter syndrome,[2] or Bartarlla-Scott syndrome.

An appearance of a widened nasal bridge can be seen with dystopia canthorum, which is a lateral displacement of the inner canthi of the eyes.[3] Dystopia canthorum is associated with Waardenburg syndrome.[4]
