A Novel Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) 3D Printing Method for Nasal Framework...

Area of Science:

• Plastic Surgery
• Biomedical Engineering
• Reconstructive Surgery

Background:

• Nasal resection presents significant reconstructive challenges, often requiring complex free flap procedures.
• Achieving optimal aesthetic and functional outcomes in total or subtotal nasal reconstruction remains difficult.

Purpose of the Study:

• To introduce a novel method for nasal framework reconstruction using advanced CAD/CAM and 3D printing technologies.
• To improve the precision and success rates of free flap reconstructions for total or subtotal nasal defects.

Main Methods:

• Utilized computer-aided design (CAD) and computer-aided manufacturing (CAM) to develop a patient-specific nasal framework.
• Employed novel 3D printed guides to accurately recreate the nasal cartilage framework.
• Performed subtotal nasal reconstruction using a fasciocutaneous free flap supported by the 3D printed template.

Main Results:

• Successfully reconstructed the nasal framework using a free flap.
• Demonstrated the efficacy of CAD/CAM and 3D printed guides in achieving a precise reconstruction.
• The novel approach facilitated a successful free flap reconstruction of the nasal framework.

Conclusions:

• The presented CAD/CAM and 3D printing approach offers a promising solution for challenging nasal reconstructions.
• This technique enhances the accuracy of nasal framework creation, leading to improved reconstructive outcomes.
• This novel method provides a valuable tool for surgeons performing total or subtotal nasal reconstructions.
