This 3D model combines a midsagittal section of the head with preservation of brain and cranial cavity anatomy, with a unique deep dissection of the pharyngeal region via removal of basicranial bone and the anterior parts of the atlas and axis. As the opposing side is undissected it has been digitally eliminated from the model.

Within the endocranial cavity the preservation of dura mater retains the superior sagittal sinus across much of its course from anterior to posterior, reaching the confluence of sinuses visible in cross-section. Both the tentorium cerebelli and the falx cerebelli are preserved. The cerebrum is well-reserved with retention of the cingulate gyrus and sulcus, and removal of the septum pellucidum inferior to the corpus callosum providing a view into the lateral ventricle (with retention of the interventricular foramen at the inferior margin of the septum). The diencephalon and midbrain structures (epithalamus, colliculi, mamillary body, infundibulum) are all appreciable in cross-section as is the cerebellar hemisphere and fourth ventricle. Small views of the anterior cerebral and posterior inferior cerebellar arteries are visible (and false colored).

Outside the endocranium, removal of parts of the occipital, temporal and sphenoid bones (alongside the atlas and axis) has been coupled with removal of the pharyngeal constrictors, carotid sheath and oral mucosa to demonstrate a unique view of several key neurovascular and glandular structures. Within the zone of removed tissue there is partial exposure of the right common carotid artery within the dissected petrous portion of the temporal, as well as partial exposure of the left vertebral artery through disruption of the occipital and dural covering.

The medial and lateral pterygoids are exposed near the posterior margin of the largely intact nasal cavity. Between the exposed dura and medulla and the pterygoids (and trapped deep to the sectioned and reflected stylohyoid muscle) the dissected carotid sheath has exposed the internal jugular vein, the vagus nerve, the internal carotid artery (with overriding ascending pharyngeal artery from the external carotid artery), and the sympathetic trunk (with superior cervical ganglion and internal carotid nerve). Immediately anterior to this bundle of neurovascular structures is the external carotid artery, giving rise to the ascending pharyngeal artery, a common trunk for the lingual and facial arteries, and then continuing superiorly out of the plane of dissection. The submandibular gland can be seen resting on the mylohyoid muscle near the lingual artery (which passes deep relative to the gland), with the duct passing towards the genu of the mandible and the origin of the reflected genioglossus muscle. At the inferior border of the specimen, the reflected margin of the dissected tongue the hypoglossal nerve can be seen deep to the lingual artery.

Advantages of 3D Printed Anatomical Models

  • 3D printed anatomical models are the most anatomically accurate examples of human anatomy because they are based on real human specimens.
  • Avoid the ethical complications and complex handling, storage, and documentation requirements with 3D printed models when compared to human cadaveric specimens.
  • 3D printed anatomy models are far less expensive than real human cadaveric specimens.
  • Reproducibility and consistency allow for standardization of education and faster availability of models when you need them.
  • Customization options are available for specific applications or educational needs. Enlargement, highlighting of specific anatomical structures, cutaway views, and more are just some of the customizations available.

Disadvantages of Human Cadavers

  • Access to cadavers can be problematic and ethical complications are hard to avoid. Many countries cannot access cadavers for cultural and religious reasons.
  • Human cadavers are costly to procure and require expensive storage facilities and dedicated staff to maintain them. Maintenance of the facility alone is costly.
  • The cost to develop a cadaver lab or plastination technique is extremely high. Those funds could purchase hundreds of easy to handle, realistic 3D printed anatomical replicas.
  • Wet specimens cannot be used in uncertified labs. Certification is expensive and time-consuming.
  • Exposure to preservation fluids and chemicals is known to cause long-term health problems for lab workers and students. 3D printed anatomical replicas are safe to handle without any special equipment.
  • Lack of reuse and reproducibility. If a dissection mistake is made, a new specimen has to be used and students have to start all over again.

Disadvantages of Plastinated Specimens

  • Like real human cadaveric specimens, plastinated models are extremely expensive.
  • Plastinated specimens still require real human samples and pose the same ethical issues as real human cadavers.
  • The plastination process is extensive and takes months or longer to complete. 3D printed human anatomical models are available in a fraction of the time.
  • Plastinated models, like human cadavers, are one of a kind and can only showcase one presentation of human anatomy.

Advanced 3D Printing Techniques for Superior Results

  • Vibrant color offering with 10 million colors
  • UV-curable inkjet printing
  • High quality 3D printing that can create products that are delicate, extremely precise, and incredibly realistic
  • To improve durability of fragile, thin, and delicate arteries, veins or vessels, a clear support material is printed in key areas. This makes the models robust so they can be handled by students easily.
