Area of Science:

Plastic Surgery
Biomedical Engineering
Medical Imaging

Background:

Advancements in 3D simulation, tissue engineering, and 3D printing are revolutionizing plastic surgery.
Augmentation rhinoplasty has long faced challenges in ideal material and design selection.
These emerging technologies hold significant promise for improving augmentation rhinoplasty procedures.

Purpose of the Study:

To validate the clinical feasibility of a 3D carving simulation and patient-specific implant fabrication system.
To assess the reproducibility of the 3D carving system through rigorous testing.

Main Methods:

Patient-specific implants were designed using preoperative CT scans and custom software.
3D printing was utilized to create negative molds for silicone implants.
Ten silicone implants were fabricated and compared to virtual designs; seven patients underwent surgery with postoperative CT confirmation.

Main Results:

Actual implants demonstrated high accuracy, with a mean difference of 0.07 mm (0.17% ± 0.11%) compared to virtual designs.
Implant fit varied along the length, with the highest accuracy at the cephalic end (100%) and decreasing accuracy towards the caudal end.

Conclusions:

The 3D carving system provides an intuitive, rapid, and accurate method for fabricating patient-specific rhinoplasty implants.
This technology has the potential to enhance rhinoplasty outcomes, regardless of surgeon experience.
The system's accuracy supports its clinical utility in augmentation rhinoplasty.
