This vessel runs from the sphenoid forward and downward along the vomer to the anterior dental foramen, and in its course gives off numerous branches which supply most of the surface of the nasal septum. Exostoses. Exostoses (or spurs) ordinarily occur along the line of junction between the triangular cartilage and the vomer, in which case they may be either cartilaginous or bony. If they occur posteriorly they develop between the line of junction of the A, Diagram Showing a Cross-section of the Nose, with Deflected Septum and Thickening Over the Cartilage Which Fills in the Gap Left in the Sutures Where the Parts of the Septum are Joined. The cartilage is pictured in the center. Ii, Shows a section of such a septum farther forward. The deflection is to the left. The thickening is low down. septal plate of the ethmoid and the vomer. Ordinarily they are composed partly of cartilage and partly of bone. As these exostoses ordinarily form along the line of junction of the septal plate of the ethmoid and the vomer, and at the exact point where the edges of these bones are grooved to form a foramen which holds the projection of the triangular cartilage, it follows that in removing a bony exostosis one sometimes cuts through the mucous membrane, then through a thin layer of bone, then into cartilage, and again into another thin layer of bone and mucous membrane.
