Summary
The orbitozygomatic infratemporal fossa approach significantly enhances neurosurgical access, increasing surgical exposure by up to 300% and reducing surgeon-to-field distance for complex skull base procedures.
Area of Science:
- Neurosurgery
- Anatomy
- Surgical Techniques
Background:
- Skull base surgery presents challenges in achieving adequate exposure.
- Traditional approaches may limit visualization of critical neurovascular structures.
Purpose of the Study:
- To quantify the benefits of the orbitozygomatic infratemporal fossa approach for neurosurgical access.
- To evaluate the increase in surgical exposure and operative field proximity.
Main Methods:
- Detailed cadaveric dissections were performed.
- The orbitozygomatic infratemporal fossa approach was utilized.
- Surgical window dimensions and surgeon-to-field distances were measured.
Main Results:
- Exposure increased by up to 300% compared to standard approaches.
- Surgical window facilitated access to P2 segment of posterior cerebral artery and basilar bifurcation.
- Surgeon-to-operative field distance decreased by 2-3 cm.
- Simultaneous access to infratemporal fossa, pterygopalatine fossa, and orbit was achieved.
Conclusions:
- The orbitozygomatic infratemporal fossa approach is an effective technique for enhancing skull base exposure.
- This approach offers significant advantages in visualizing complex neurovascular anatomy.
- It provides a wider surgical window and improved ergonomics for neurosurgeons.

01:14Cranial Bones: Superior and Posterior View
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,...

01:27Cranial Bones: Lateral View
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...
