what is a nasal margin
The nasal bone is a bilateral symmetrical paired bone of the face. Their superior borders and main bodies form the bridge of the nose while the inferior borders connect with the nasal cartilage to form the superior margin of the nasal aperture.he nasal bones are ossified intramembranously via the cartilaginous nasal capsule. Clinically the hypoplasia or absence of nasal bones is a common feature in Down syndrome (trisomy 21) and other chromosomal abnormalities.
