Summary
Facial prostheses restore appearance after cancer surgery but face retention challenges. This report details a two-piece prosthesis using magnets for improved retention in midfacial defects.
Area of Science:
- Maxillofacial prosthetics
- Biomaterials science
- Reconstructive surgery
Background:
- Facial defects from cancer resection often require prostheses for functional and aesthetic restoration.
- Challenges in facial prosthesis retention include prosthesis size, weight, and anatomical limitations.
- Current retention methods include adhesives, attachments, clips, osseointegrated implants, and magnetic connectors.
Observation:
- This clinical report focuses on a patient with a lateral midfacial defect.
- A two-piece prosthesis was designed, comprising an extraoral facial prosthesis and an intraoral obturator.
- Magnets were utilized to connect the extraoral and intraoral components.
Findings:
- The magnetic connection between the extraoral facial prosthesis and the intraoral obturator provided a viable retention solution.
- This approach facilitated the rehabilitation of the lateral midfacial defect.
- The two-piece design with magnetic linkage addressed the challenges of prosthesis size and weight.
Implications:
- Magnetic retention offers a promising alternative for securing facial prostheses, particularly in complex midfacial defects.
- This technique can improve patient quality of life by enhancing prosthesis stability and function.
- Further research into magnetic retention systems for maxillofacial prosthetics is warranted.
