Nasal bridge
 | This article about biology may be excessively human-centric. |
The nasal bridge is the upper, bony part of the nose, which overlies the nasal bones.
Association with epicanthic folds
[edit]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
[edit]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. A broad nasal bridge can be a sign of Snijders Blok–Campeau syndrome.[3]
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.[4] Dystopia canthorum is associated with Waardenburg syndrome.[5]
