Summary
Titanium pre-bent implants offer a solution for reconstructing defects after maxillary tumor surgery. While generally well-tolerated, a small percentage experienced extrusion, requiring further surgery.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Engineering
- Oncology
Background:
- Maxillectomy for tumors often results in significant defects, posing reconstruction challenges.
- Advancements in 3D printing have led to the development of titanium pre-bent implants for orbital reconstruction.
Purpose of the Study:
- To evaluate the post-operative tolerance of titanium pre-bent implants used for orbital wall and floor reconstruction following maxillectomy.
- Assess functional, aesthetic, and quality of life outcomes.
Main Methods:
- Retrospective analysis of 11 patients undergoing maxillectomy with orbital floor resection and reconstruction using PorousiTi® titanium implants.
- Evaluation of implant tolerance based on re-operation for infection or extrusion within 6 months post-procedure.
Main Results:
- No post-operative infections were reported in any patients.
- Two patients (18.2%) required re-operation due to implant extrusion and skin exposure within the follow-up period.
- Satisfactory aesthetic and functional results were achieved in the majority of cases.
Conclusions:
- Titanium pre-bent implants demonstrate good tolerance for orbital reconstruction after maxillectomy.
- While complications like extrusion can occur, they are infrequent, and the implants provide satisfactory functional and aesthetic outcomes.
