Begin with 3D endoscopic landmark anatomy and corridors; advance through approaches, reconstruction, complications, and case-based mastery. Designed for board-certified neurosurgeons — not a surgical qualification.
Module 01 / Surgical Orientation
A fellowship begins with landmarks — not with a random clinical case.
Know the sphenoid sinus, opticocarotid region, parasellar ICA, sellar floor, clival surface and lateral landmarks before debating a corridor or intervention.

Endoscopy & Instrumentation
Visualization, angled optics, ergonomics, two-surgeon four-hand choreography and instrumentation.
Structured case planning, advanced oral examination and longitudinal formative assessment.
Independent theoretical mastery
Only Stage 01 is implemented as a complete interactive learning sample. Stage 02 is an interactive introductory atlas; stages 03–08 are syllabus previews.
This original synthetic model places the sella, clivus, bilateral carotid courses, optic apparatus and lateral landmarks in a navigable teaching space. It is not a patient-derived CT, operative dissection, calibrated anatomy or a surgical navigation tool.

Selected anatomy
Select an anatomical structure
Tap an anatomical label or colored surface. Use one finger to rotate. Two fingers zoom. The selected structure will highlight and a fellowship-level pearl will appear here.
Endoscopic orientation
View the sellar region as a 3D landmark map. In actual surgery, anatomical variants, sphenoid pneumatization and vessel dehiscence must be checked on patient-specific imaging.
Surfaces are illustrative, not to scale; the model omits most cranial nerves, sinus septations, vascular variants and patient-specific measurements.
Illustrations beside the interactive model
Anatomy reference plates
If your 3D view is blank, these embedded illustrations will still display. Compare the anatomy in different planes, then return to the rotatable lab above.
Tap structures in the 3D scene or use these buttons. Completing all three tasks unlocks the completed-lesson badge (for this prototype).
0 / 3 landmark objectives confirmed. Select each structure to record recognition.
Module 02 · Conceptual anatomical atlas
Choose an endonasal corridor
Select a module to highlight its approximate territory on the original 3D model. Corridors are conceptual teaching overlays, not validated surgical boundaries or operative plans.
Assess expected dural defect, CSF flow, prior surgery and vascularized tissue availability with the skull-base team.

How do sphenoid pneumatization and septal insertions alter anatomical confidence?
The pneumatization pattern and intersinus septa vary. A septum can insert onto a carotid prominence, and bone over neurovascular structures can be thin or absent. Patient-specific CT assessment is required before using a bony surface as an assumed safe landmark. An illustrative 3D model cannot establish dehiscence or course.
Which boundaries most influence transplanum / transtuberculum exposure?
Consider the optic apparatus, medial opticocarotid relationships, suprasellar cistern anatomy, anterior communicating complex and the relation of the pathology to the chiasm and pituitary stalk. The approach is selected by individual anatomy and lesion position, not simply by a pathology label.
Why is the vidian corridor relevant to a transpterygoid extension?
The vidian canal/nerve is a recognized landmark toward the lacerum ICA in lateral endonasal anatomy. It does not independently provide a safe trajectory. Detailed imaging, variant anatomy and supervised cadaveric dissection are essential for spatial confirmation.
What makes a high-flow intradural CSF defect different?
Reconstruction strategy must account for defect geometry, cisternal or ventricular communication, the integrity and availability of vascularized flaps, prior treatments and overall postoperative leak risk. Outcomes depend on coordinated skull-base reconstruction, not a single standard material.
How should an ICA injury concern change the learning sequence?
Vascular risk recognition and crisis team communication should precede advanced procedural simulation. Practical rescue maneuvers require controlled laboratory or clinical team training and institution-specific emergency protocols; a browser animation is not an appropriate substitute.
Scientific grounding
References & Training Limitations
The teaching framework draws from recognized skull-base educational programs and anatomical reviews. The model graphics are independently generated synthetic geometry; no clinical segmentation or proprietary anatomy assets are included.
UPMC · Complex Endoscopic Endonasal Course
Advanced expanded and coronal approaches, 3D anatomy, complication recognition, ICA injury simulation.
Training scope: Post-board theoretical education and spatial reasoning only. Not a substitute for cadaveric dissection, hands-on mentorship, accredited fellowship training, clinical credentialing, original imaging, or local institutional protocols.
