Bony Nasal Vault

Abstract

The bony nasal vault is composed of the two nasal bones, attached to the frontal bone superiorly and laterally to the maxillary bones. There is a curving transition with the frontal bones, and inferiorly the nasal bones overlie and protect the insertion of the upper lateral cartilages, which attach to their undersurface. Although the nasal bones are a paired structure attached to each other and to two other bones superiorly and laterally, it is advantageous in most revisional circumstances to consider the bones as a single bony complex. In some cases, however, it will be necessary to split them apart and move them medially or lat- erally as separate entities.
