Dysmorphology
Low nasal bridges are closely associated with epicanthic folds; a lower nasal bridge is more likely to cause an epicanthic fold, and vice versa.
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 or fetal alcohol 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. Dystopia canthorum is associated with Waardenburg syndrome.
