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

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

Patients to be recruited :

* 80 randomised equally into the 2 groups
* age range: 21 -70
* includes orbital wall defects from trauma confirmed by Computer Tomographic (CT) scans, 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
* all patients will be seen \& assessed in the Plastic \& Ophthalmology outpatient clinics by Principal Investigator (PI) and collaborators

End point :

* endpoint for follow-up is 12 months
* all patients are assessed for assessed for diplopia, enophthalmos, exophthalmos, visual acuity, mobility of the globe, contour symmetry
* all patients will have a Computer Tomographic (CT) scan of the orbits at 12 months to assess the bony orbit \& orbital volume
* patients will be discharged from follow up at 12 months if asymptomatic
* patients with complications will exit the protocol \& will be treated on their merits eg. infection - removal of implant, etc

Data Management :

* maintained by the Principal Investigator (PI) under repository of the Research \& Development Office, National Healthcare Group (NHG) / National University Health Systems (NUHS), Singapore
* no data will be released without the permission of the Principal Investigator (PI) \& the Research \& Development Office, National Healthcare Group (NHG) / National University Health Systems (NUHS), Singapore

Eligibility Criteria:
Inclusion Criteria:

* age 21 y - 70 y
* both males / females included
* orbital fractures
* defect after orbital osteotomies

Exclusion Criteria:

* patient refusal
* infection around the orbit / generalised infection
* Diabetes mellitus
* allergies to polycaprolactone \& its analogues
* allergies to titanium
