Improving pre-operative planning with personalized 3D printing: Removing a maxillary sinus tumor

  • Oncology

The Case

An 85-year-old male presented with a large lower-eyelid, cheek and nasal tumor. The tumor's size and location was causing both orbital invasion and maxillary invasion and needed surgical intervention. Working with 299 CT images from the hospital, Axial3D produced two 3D printed models and a 3D visualization to support pre-operative planning for the maxillectomy procedure.

The Solution

The first model was used to pre-bend the plate of the orbital floor ahead of surgery, while the second model was used to support intra-team communication between the cranio-facial and neurosurgery teams.

The Benefits of using a 3D Model

Operating room time can be reduced by up to 60% when surgeons use a 3D model to pre-bend plates, leading to a reduction in cost and risks and improving the overall surgical outcome.

It can be difficult to define a robust surgical plan for tumor surgeries, but in this case, having access to a 3D representation of the patient’s anatomy ahead of time removed intra-team variation between the cranio-facial and neurosurgery teams. This saved approximately 80 minutes of time between planning and operating and helped the team define a robust pre-operative plan.

The interactive 3D visualization was used as a reference intraoperatively while removing the tumor, providing insights as and when required during the procedure.

Utilizing all three models provided by Axial3D, the clinicians were able to define a plan, reduce planning and operative time, improve patient care and ensure the tumor was fully removed.
