What passes through stylomastoid foramen?
It is located on the inferior surface of the petrous temporal bone, between the base of the styloid process and the mastoid process of the temporal bone. It transmits the facial nerve and stylomastoid artery (branch of posterior auricular artery).

What is the ophthalmic artery?
The ophthalmic artery (OA) is the first branch of the internal carotid artery distal to the cavernous sinus. Branches of the OA supply all the structures in the orbit as well as some structures in the nose, face and meninges. Occlusion of the OA or its branches can produce sight-threatening conditions.
