Summary
Immediate patient-specific implants (PSIs) made of polyetherketoneketone (PEKK) accurately reconstruct temporal hollowing after surgery. This study shows PEKK PSIs offer a safe and esthetically pleasing solution for temporal hollowing correction.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Science
- Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM)
Background:
- Temporal hollowing is a common complication following temporalis muscle flap (TMF) surgery for maxillofacial reconstruction.
- Accurate and predictable reconstruction of this defect is crucial for patient outcomes and esthetics.
Observation:
- This case series evaluated ten patients undergoing maxillofacial reconstruction with TMF.
- Preoperative planning involved virtual surgical planning software utilizing multislice CT scans.
- Patient-specific implants (PSIs) were fabricated from polyetherketoneketone (PEKK) material.
Findings:
- The study demonstrated a highly accurate duplication of PSIs using a template-molding workflow.
- Postoperative follow-up for 12 months showed no signs of infection or implant mobilization.
- A point-based analysis revealed a mean difference of 0.0373 (±0.3036) mm between the fabricated implants and the 3D preoperative plan.
Implications:
- Immediate CAD/CAM reconstruction with PEKK PSIs is a viable and accurate treatment option for temporal hollowing.
- The use of PEKK PSIs leads to uneventful healing and high esthetic acceptance by patients.
- This workflow offers a predictable solution for improving patient appearance and satisfaction after TMF surgery.
