Biomaterials for orbital fractures repair

Area of Science:

• Ophthalmology
• Oral and Maxillofacial Surgery
• Biomaterials Science

Background:

• Orbital fractures occur in 10-25% of facial fractures, primarily affecting individuals in their third decade.
• Reconstruction of the orbital floor is crucial for globe support and restoring orbital shape, especially when bone fragments are missing or comminuted.
• The complex orbital anatomy necessitates precise implant contouring for anatomical restoration.

Purpose of the Study:

• To highlight the challenges in selecting appropriate materials for orbital fracture repair.
• To discuss the controversy surrounding various biomaterials and implant designs for orbital reconstruction.

Main Methods:

• Review of existing literature on orbital fracture management.
• Analysis of material properties and clinical outcomes for different reconstruction techniques.

Main Results:

• The choice of reconstruction material (resorbable vs. non-resorbable, autogenous vs. alloplastic, etc.) is highly debated.
• Plate design (preformed vs. custom-made, porous vs. non-porous) also impacts surgical outcomes.
• No single material or technique is universally superior, demanding careful consideration by surgeons.

Conclusions:

• Material selection for orbital reconstruction is complex and controversial.
• Ophthalmologists and oral and maxillofacial surgeons face significant challenges in choosing optimal materials and techniques.
• Further research may be needed to establish evidence-based guidelines for orbital implant selection.
