The lateral skull base: a vascular perspective with clinical implications
Skull Base Surgery
|January 1, 1991
Summary
Detailed study of lateral temporal region microvascular anatomy reveals a layered blood supply crucial for skull base surgery. This finding impacts both ablative and reconstructive surgical approaches.
Area of Science:
- Neurosurgery
- Anatomy
- Vascular Surgery
Background:
- Surgical management of skull base disease requires detailed understanding of regional microvascular anatomy.
- The lateral temporal region's vascular supply is critical for surgical planning.
Purpose of the Study:
- To investigate the microvascular anatomy of the lateral temporal region.
- To elucidate the vascular supply to the periosteum and outer table of the skull.
- To identify implications for skull base surgery.
Main Methods:
- Injection of colored methyl methacrylate into major blood vessels of six human cadaver heads.
- Detailed visualization of vascular anatomy and its relationship to scalp layers.
- Histological examination to identify vascular networks and perforators.
Main Results:
- Each named blood vessel was accompanied by a deeper vessel supplying the periosteum and outer skull table.
- A capillary network in the periosteum was observed, with perforators entering the bone.
- A previously undescribed arterial plexus was identified in the infratemporal fossa.
Conclusions:
- The layered vascular supply to the skull has direct implications for ablative and reconstructive skull base surgery.
- Understanding this anatomy can optimize surgical outcomes and minimize complications.
- Identification of the infratemporal fossa arterial plexus warrants further investigation.

Cranial 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...

Veins of Head and Neck
The blood drainage from the head and neck is primarily managed by three pairs of veins: the external jugular, internal jugular, and vertebral veins. The external jugular veins drain superficial scalp and face structures, passing over the sternocleidomastoid muscles to empty into the subclavian veins.
On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...

Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Overview of the Skull
The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...

Cranial 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,...

Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
