Bony Tunnel Formation Associated with the Distal Segment of the Frontal Branch of the Middle Meningeal Artery.

The knowledge of certain anatomical variations is fundamental and any surgeon who operates without that knowledge may encounter difficulty during surgery. In this context, there is the middle meningeal artery (MMA) which also engenders considerable clinical interest due to its location. The MMA is predominantly periosteal, irrigating the bone and dura mater.
