Summary
A new digital nose database and 3D printing process streamline the creation of nasal prostheses for rhinectomy patients. This innovative method reduces patient strain by eliminating traditional physical modeling steps.
Area of Science:
- Medical Device Technology
- Biomedical Engineering
- Digital Health
Background:
- Development of a digital nose database for patients requiring nasal prostheses after rhinectomy.
- Challenges in using mirrored computer-aided design (CAD) data due to the nose's unpaired structure.
Purpose of the Study:
- To create a digital nose database for improved nasal prosthesis fabrication.
- To implement a streamlined workflow for patient-specific nasal prostheses.
Main Methods:
- Digitization of 202 individuals' faces using 3D scanning.
- Nose scaling, measurement, and classification using objective criteria.
- Application of epiTecture software for virtual fitting and adaptation, followed by 3D printing of a thermopolymer model.
Main Results:
- Successful development of a digital nose database at University Hospital Dresden using epiTecture software.
- Demonstration of the workflow with a patient case study.
Conclusions:
- The digital workflow significantly differs from conventional nasal prosthesis production.
- Elimination of physical modeling reduces patient strain and improves the fabrication process.
