Vomer
The sword bone is a small flat bone forming part of the nasal septum.
Anatomical Structures
The sagittally positioned bone forms the dorsocaudal part of the nasal septum. Using the wing-like lamellae of the alae vomeris, it mounts to the rostrum and body sphenoid bone. It connects caudally to the ``crista nasalis hard palate in the midline. The scapula has a ventrocranial connection with the lamina perpendicularis ossis ethmoidalis.
Most common variations
Thanks to the deviation of the nasal septum, the vomer is also deviated, almost always. Other variations may arise due to incomplete ossification.
