Sutures of the Skull

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...

Cranial Bones: Lateral View

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...

Cranial Bones: Superior and Posterior View

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,...

Overview of the Skull

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...

Area of Science:

Neurosurgery
Anatomical Dissection
Surgical Simulation

Context:

Skull base surgery requires precise anatomical understanding and dissection techniques.
Cadaveric specimens are crucial for training neurosurgeons in complex skull base approaches.
Existing holders may limit positioning and access during dissection.

Purpose:

To present an original, multipositional holder for skull base cadaveric specimens.
To provide a stable and versatile platform for laboratory micro neurosurgical dissection.
To facilitate simulation operations and enhance surgical training.

Summary:

The developed holder is constructed from durable stainless steel for easy cleaning and maintenance.
It features a three-point fixation system with thin needles for secure specimen mounting.
The holder offers extensive angular mobility, allowing specimens to be positioned in any desired orientation.

Impact:

Enables unobstructed surgical dissection by providing a clear view of the operative field.
Improves the realism and effectiveness of skull base surgical training and simulation.
Offers a practical and adaptable solution for neurosurgical laboratories and educational settings.
