Stereoscopy in Surgical Neuroanatomy: Past, Present, and Future.

Since the dawn of antiquity, scientists, philosophers, and artists have pondered the nature of optical stereopsis-the perception of depth that arises from binocular vision. The early 19th century saw the advent of stereoscopes, devices that could replicate stereopsis by producing a 3D illusion from the super-imposition of 2D photographs. This phenomenon opened up a plethora of possibilities through its usefulness as an educational tool-particularly in medicine.

Middle Meningeal Artery to Premeatal Anterior Inferior Cerebellar Artery Bypass via Anterior Petrosectomy: An Anatomic Feasibility Study.

Background: Anterior inferior cerebellar artery (AICA) aneurysms are rare with no optimal consensus on management strategies. When treatment requires parent artery occlusion, postoperative ischemic or neuropathic complications can occur. This study evaluated the feasibility of direct revascularization of premeatal AICA using the middle meningeal artery (MMA) as the donor through an anterior petrosectomy window.
