• The vomer (or vomer bone, latin: vomer) is an unpaired midline bone which along the perpendicular plate of the ethmoid forms the nasal septum.

    The vomer is a single facial bone that takes a form of a plate and its superior border gives two extensions called wings. With the help of these wings the vomer attaches to the inferior surface of the body of the sphenoid bone. The vomer also articulates with the ethmoid, both palatine bones, and both maxillary bones.

    The vomer is situated in the sagittal plane and forms part of the inferior part of the nasal septum, while the perpendicular plate of the ethmoid bone forms the superior part.
