This protocol describes a procedure to track the evolution of mesial network measures in temporal lobe epilepsy (TLE) patients. It is based on the combination of intracranial recordings with a novel numerical technique for data analysis. Specifically, we present a protocol for network analyses of foramen ovale recordings.

The closure of a patent foramen ovale (PFO) is a catheter-based intervention to prevent PFO-associated stroke. The PFO-occlusion device is advanced through the femoral vein and deployed across the interatrial septum using transesophageal echocardiography (TEE) and fluoroscopic guidance. The following protocol provides a step-by-step guide for the PFO-closure intervention using a double-disc device.

(2015).This video demonstrates the facial nerve crush procedure in a mouse, where blunt dissection through key landmarks exposes the facial nerve trunk at the stylomastoid foramen. Forceps are then used to compress the nerve trunk, inducing axonal damage and disrupting neuronal signal transmission.

FAQs
The location creates a fixed reference for following cranial nerve VII as it passes from the temporal bone toward the face. Because the opening lies between the styloid and mastoid processes, its relationship to those processes helps orient temporal bone anatomy and supports interpretation of where the nerve leaves the facial canal.
The stylomastoid artery is an additional structure associated with this passage. Recognizing that it accompanies the facial nerve at the foramen helps distinguish the neurovascular contents of the opening from surrounding temporal bone features. This relationship is useful when researchers map the nerve’s exit and interpret local anatomy in relation to facial nerve disorders.
At this landmark, the facial nerve’s course changes from a pathway within the temporal bone and facial canal to an extracranial pathway toward the face. That transition gives the foramen functional importance: it connects the bony portion of the nerve’s route with the portion relevant to facial movement, helping organize neuroanatomical descriptions.
To use the landmark in an anatomical study, first orient the temporal bone by locating the styloid and mastoid processes, then identify the opening between them. The facial nerve can be followed from the facial canal to this exit and onward toward the face. This workflow connects bone, nerve course, and facial motor function.
Facial weakness or paralysis can be considered alongside the nerve’s relationship to this exit. The overview identifies injury, inflammation, and compression as causes of such disorders, so the foramen provides a reference point for understanding whether facial nerve involvement may relate to its passage out of the temporal bone.
In neuroscience education and research, the Stylomastoid Foramen links three levels of analysis: temporal bone structure, cranial nerve VII trajectory, and facial movement. Studying these together shows why a small bony landmark matters beyond anatomy alone. It supports tracing the nerve, interpreting temporal bone relationships, and framing disorders that affect facial movement.
