Area of Science:

  • Maxillofacial surgery
  • Biomaterials engineering
  • Medical imaging

Background:

  • Orbital wall fractures are common maxillofacial injuries requiring precise reconstruction.
  • Traditional methods (autologous grafts, alloplastic implants) face limitations like variability and imprecise contour restoration.
  • Patient-specific implants (PSIs) represent a significant advancement in orbital reconstruction.

Purpose of the Study:

  • To review the evolution of orbital fracture reconstruction techniques.
  • To detail the design and fabrication of patient-specific implants (PSIs).
  • To assess the clinical evidence, limitations, and future directions of PSIs in orbital reconstruction.

Main Methods:

  • Review of literature on orbital reconstruction techniques.
  • Analysis of patient-specific implant (PSI) design and manufacturing principles.
  • Evaluation of clinical outcomes and evidence supporting PSI use.

Main Results:

  • Patient-specific implants (PSIs) offer highly accurate anatomical restoration for orbital fractures.
  • PSIs reduce intraoperative manipulation and improve clinical outcomes.
  • The review highlights advancements from traditional grafts to modern 3D-designed implants.

Conclusions:

  • Patient-specific implants (PSIs) have transformed orbital reconstruction, offering superior accuracy and outcomes.
  • Future directions include bioactive materials, AI-driven design, and point-of-care 3D printing for PSIs.
  • PSIs are crucial for preventing long-term sequelae like enophthalmos and facial asymmetry.
