Vomerovaginal canal

The vomerovaginal canal is a small paired variably present canal between the alae of the vomer and the vaginal processes of the sphenoid bone body. It is medial to the palatovaginal canal.

When present it transmits the sphenopalatine vessels.

Practical points

Knowledge of the anatomy of vomerovaginal canal, palatovaginal canal and its relationship to the sphenoid sinus is very helpful in endoscopic trans-sphenoidal surgeries .
