Polycaprolactone / Tricalcium Phosphate (PCL/TCP) v Titanium Orbital Implant : Randomised Trial

Fractures, Enophthalmos, Diplopia

Orbital, fractures, enophthalmos, diplopia, eye

Hypothesis: Polycaprolactone / Tricalcium Phosphate Orbital (PCL / TCP) Implant is as effective in the reconstruction of the Orbital walls as Titanium Mesh implant. In this study we will be conducting a randomised trial to compare implants made of 2 materials for Orbital reconstruction * Polycaprolactone / Tricalcium Phosphate (PCL / TCP) * Titanium Patients to be recruited : * 80 randomised equally into the 2 groups * age range: 21 - 70 * includes orbital wall defects from trauma, after osteotomies * excludes patients with Diabetes Mellitus, known allergies to polycaprolactone & its analogues, know allergies to Tricalcium Phosphate & its analogues, infections generalised & around the orbital region Trial Duration: April 2010 - March 2015 Follow up: * postoperative 1 week, 1 month, 3 months, 6 months, and 12 months * Computer Tomographic (CT) scan of Orbits immediate postoperative and at 12 months appointment
