Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

9.1K
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,...

Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

8.3K
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...

Sutures of the Skull01:22

Sutures of the Skull

14.8K
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...

Area of Science:

  • Biomedical Engineering
  • Surgical Simulation
  • Otolaryngology-Head and Neck Surgery

Background:

  • Additive manufacturing (3D printing) is increasingly practical and affordable.
  • 3D printing has potential applications in Otolaryngology-Head and Neck Surgery.
  • Temporal bone surgical simulation is a promising area for 3D printing.

Purpose of the Study:

  • To create a simulated, multicolor, multi-material temporal bone model using 3D printing.
  • To evaluate the safety and benefit of these models in training for temporal bone surgical cases.

Main Methods:

  • 3D representations of human temporal bones were generated from CT scans using image processing software.
  • Multi-material models were 3D printed.
  • Attending and resident otolaryngologists dissected the models in a temporal bone laboratory.
  • Models were graded for anatomical accuracy and suitability for temporal bone drilling simulation using a 5-point Likert scale.

Main Results:

  • The 3D printed temporal bone models exhibited significant anatomical detail.
  • The models closely resembled human cadaver specimens for drilling and dissection procedures.

Conclusions:

  • Simulated temporal bones produced via 3D printing can benefit surgical training.
  • These models are suitable for preoperative simulation of complex otologic cases.
  • The models can be used for standardized testing of temporal bone surgical skills.
