Posterior ethmoidal nerve
The posterior ethmoidal nerve is a nerve of the head. It is a branch of the nasociliary nerve (itself a branch of the ophthalmic nerve (CN V1)). It provides sensory innervation to the sphenoid sinus and ethmoid sinus, and part of the dura mater in the anterior cranial fossa.
The posterior ethmoidal nerve is a branch of the nasociliary nerve.
It passes through the posterior ethmoidal foramen alongside the posterior ethmoidal artery.
Within the anterior cranial fossa, it issues a branch to which innervates part of the dura mater.
It gives branches to the sphenoid sinus and the ethmoid sinus.
The posterior ethmoidal nerve is absent in a significant proportion of people. This may be around 30%.
The posterior ethmoidal nerve supplies sensation to the sphenoid sinus and the ethmoid sinus. It also supplies sensation to part of the dura mater in the anterior cranial fossa.
The posterior ethmoidal nerve is present in other animals, including horses. Headshaking can sometimes be treated with analgesia or neurectomy of the posterior ethmoidal nerve.
