Maxillary reconstruction using a multi-element free fibula flap based on a three-dimensional polyacrylic resin model

Area of Science:

• Oral and Maxillofacial Surgery
• Biomedical Engineering
• 3D Printing Technology

Background:

• Mid-facial defects often require complex reconstruction to restore function and aesthetics.
• Traditional planning methods can be limited in visualizing intricate anatomical structures.
• Digital imaging and 3D printing offer advanced tools for surgical planning.

Observation:

• A patient with squamous cell carcinoma of the maxillary sinus underwent mid-facial reconstruction using a free fibula flap.
• Preoperative planning utilized a 3D working model created with digital printing and photocured polyacrylic resins.
• The 3D model facilitated detailed virtual resection and reconstruction planning.

Findings:

• The use of 3D polyacrylic models enabled precise preoperative planning for the complex mid-facial reconstruction.
• Virtual resection and reconstruction procedures based on the 3D model led to a highly satisfying functional and cosmetic outcome.
• The 3D model-assisted approach allowed for restoration of intraorbital structures and potential for dental implant placement.

Implications:

• 3D model-based planning can significantly improve the accuracy and efficiency of mid-facial reconstructive surgery.
• This technology aids in restoring function, enabling prosthetic rehabilitation, and achieving superior aesthetic results.
• Digital fabrication techniques represent a valuable advancement in personalized reconstructive surgery.
