Periorbital Reconstruction by "Periorbital Patch" Technique Using a Pericardium-Based Collagen Membrane and Titanium...

Area of Science:

• Ophthalmology
• Plastic and reconstructive surgery
• Biomaterials science

Background:

• Titanium mesh is utilized for orbital floor fracture reconstruction.
• Titanium mesh can elicit an inflammatory response, leading to orbital tissue adhesion.
• This adhesion causes complications such as diplopia, lid rigidity, and restricted eye movements.

Purpose of the Study:

• To evaluate if a collagen membrane barrier over titanium mesh can prevent orbital soft tissue adhesion.
• To determine if this barrier placement improves clinical outcomes in patients with orbital floor fractures.

Main Methods:

• A case study involving 106 patients undergoing periorbital restoration.
• Comparison of three groups: titanium mesh alone (72 patients), titanium mesh with autologous auricular cartilage (12 patients), and titanium mesh with a pericardium collagen membrane (22 patients).

Main Results:

• Titanium mesh alone can lead to intense inflammatory reactions and fibrosis.
• Autologous auricular cartilage provided a barrier but did not fully prevent adverse effects.
• The resorbable collagen membrane effectively prevented fibrosis and associated complications.

Conclusions:

• A barrier is beneficial to mitigate adverse effects of titanium mesh in orbital reconstruction.
• Resorbable collagen membranes serve as an effective soft tissue barrier, preventing fibrosis.
• Collagen membranes over titanium mesh offer an improved clinical outcome for orbital floor fracture repair.
