Colour stereolithography for planning complex maxillofacial tumour surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Medical Imaging
• Additive Manufacturing

Background:

• Maxillofacial tumors present complex surgical challenges.
• Preoperative planning is crucial for successful tumor resection and reconstruction.
• Traditional planning methods may lack the detailed anatomical visualization needed for complex cases.

Purpose of the Study:

• To evaluate the utility of high-precision, color stereolithography-based anatomical models in preoperative planning for maxillofacial tumor surgery.
• To assess the impact of these models on ablative and reconstructive surgical phases.
• To discuss the indications for using such models in maxillofacial oncology.

Main Methods:

• Individualized, high-precision anatomical skull models were produced using color stereolithography.
• Seven patients with complex maxillofacial tumors underwent preoperative planning utilizing these models.
• The models facilitated visualization for both tumor removal and subsequent reconstructive procedures.

Main Results:

• Color stereolithography models provided high-precision anatomical detail of patient skulls.
• These patient-specific models aided in the management of ablative surgery.
• The models also facilitated planning for reconstructive procedures, improving surgical strategy.

Conclusions:

• Preoperative planning with color stereolithography anatomical models is beneficial for complex maxillofacial tumor surgery.
• These models enhance the understanding and execution of both tumor resection and reconstruction.
• Color stereolithography offers a valuable tool for improving surgical outcomes in maxillofacial oncology.
