What is the nasal bridge?

The nasal bridge is a narrow ridge running along the upper part of the nose. It starts at the point between the eyes and continues down to the area just before the nose begins to pull out and become nostrils. The abnormal size and shape of the nose bridge may indicate genetic disease or alcohol syndrome.

The nose bridge along with the tip of the nose and nasal fabrics are the most important outer features of the nose. The nasal bridge, which is created by a meeting of two nasal bones similar to plates, is a roof above the nose. This area provides support, protection and structure into the inner parts of the nose.

Many congenital defects are characterized by a wide or low bridge. The wide bridge will have greater than a normal angle where these two, oblique nasal bones meet. In this situation, the nose appears very wide just below the eyes. The low nose bridge, often referred to as a saddle nose, curls inwards rather than running straight along the top of the ton nose. Fragile X syndrome, Downo syndrome and fetal alcoho syndromeLU is characterized by a wide or low bridge.

Fragile X syndrome is a genetic state caused by mutation on the x FMR1 x gene. Along with the wide nasal bridge, these diseases are manifested with other abnormal physical features such as a long, thin face with striking chin, large head, flat legs and free joints, as well as mental retardation and autistic behavior. The use of alcohol during pregnancy, resulting in fetal alcohol syndrome, can produce not only a low nasal bridge, but also wide-built eyes with a decrease in eyelids, genital deformities, cleft lips and heart defects.

Down syndrome is a genetic abnormality in which a person usually has extra chromosome 21, resulting in a total of 47 than the usual 46 chromosomes. This extra chromosome is responsible for the dysmorphic attributor and hands, mental retardation and heart defects common with Down syndrome. Abnormal nasal bridge, characteristic of Down syndrome, is so pronounced that it is often used as a marker for disease in fetal sonograms.

nasal bridge can be changed cosmetically with rinoplasty or decoration. Rhinoplasty can be used to narrow a wide nose or the transformation of a low bridge. The nose ornament can be made by a penetrating hole, septum or nose. The nasal bridge is pierced by griping the skin together over the bridge and pulling out the skin.
