Summary
This study developed a 3D printing workflow for temporary nasal prostheses, offering a cost-effective solution for patients awaiting facial reconstruction after cancer surgery. Patients reported high satisfaction with comfort, aesthetics, and security.
Area of Science:
- Medical Engineering
- Digital Dentistry
- Oncologic Reconstruction
Background:
- Full-thickness rhinectomies for cancer often result in significant facial defects.
- Patients frequently face prolonged periods with major facial disfigurement due to delayed reconstruction.
- Current transitional rehabilitation options are limited, impacting patient quality of life.
Purpose of the Study:
- To develop a time- and cost-effective digital workflow for 3D printing temporary nasal prostheses.
- To evaluate patient satisfaction with these temporary prostheses after oncologic surgery.
Main Methods:
- A prospective study involving patients undergoing full-thickness rhinectomies with deferred reconstruction.
- Utilized dedicated software for 3D processing of pre- and postoperative scans to design prostheses.
- Directly 3D printed prostheses using elastic transparent resin and surveyed patient satisfaction.
Main Results:
- The workflow demonstrated feasibility with a mean design time of 2h48m and printing time of 5h18m.
- Mean production cost was $753 USD.
- Patients reported high satisfaction, with median visual analog scale scores of 8/10 for aesthetics, comfort, and security.
Conclusions:
- The developed digital workflow is a feasible, time-, and cost-effective method for producing temporary nasal prostheses.
- 3D-printed temporary prostheses significantly improve patient satisfaction and help manage treatment sequelae before definitive reconstruction.
