This 3D print provides a unique medial perspective of the orbit, with the majority of the lateral wall of the nasal cavity and intervening ethmoidal sinuses carefully removed. This allows detailed visualization of the orbital contents and their close anatomical relations.
Orbital Nerves and Muscles
The posterior ethmoidal nerve (PEN), a branch of the nasociliary nerve (V1), is visible passing between the medial rectus (MR) inferiorly and the superior oblique muscle superiorly. A small portion of the orbital plate of the ethmoid bone (EB) has been retained to illustrate the nerve’s path as it enters the posterior ethmoidal foramen.
Additional Anatomical Features
Other key structures visible in this model include the frontal nerve (FN), sphenoid sinus (SS), pituitary gland (PG), and the frontal sinus mucosal lining, which is exposed after removal of the orbital plate of the frontal bone on the anterior roof of the orbit. The internal carotid artery and optic nerve are also clearly displayed, highlighting the intricate relationships within the medial orbital region.
