Summary
This study identifies five key bone pillars for the endoscopic superior eyelid transorbital approach. Understanding these anatomical landmarks enhances safety and effectiveness in skull base surgery.
Area of Science:
- Neurosurgery
- Anatomy
- Endoscopic Surgery
Background:
- The endoscopic superior eyelid transorbital approach is increasingly utilized for skull base pathologies.
- Refinement of this technique relies on detailed anatomical knowledge and surgical experience.
Approach:
- A bone-oriented anatomical review was performed using 3D analysis software.
- Dry skull and cadaveric dissections were utilized to identify key anatomical structures.
Key Points:
- Five primary bone pillars were identified: lesser sphenoid wing, sagittal crest, anterior clinoid, middle cranial fossa, and petrous apex.
- The study details the intracranial areas accessible via each bone pillar.
Conclusions:
- Consistent bone references are crucial for safe and effective endoscopic transorbital skull base surgery.
- A thorough understanding of the anatomical landmarks facilitates precise surgical navigation.

2.2K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:14Cranial Bones: Superior and Posterior View
2.2K
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
