ClinicalTrials.gov Identifier:
NCT01119144
First received: May 5, 2010
Last updated: April 24, 2014
Last verified: April 2014
  Purpose

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

Primary Outcome Measures:
  • Enophthalmos [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Assess the presence of enophthalmos after reconstruction of the orbital walls at 1 week, 1 month, 3 months, 6 months and 12 months


Secondary Outcome Measures:
  • Diplopia [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    Assess the evidence of diplopia on follow up at 1 week, 1 month, 3 months, 6 months and 12 months

  • motility of the globe [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    assess globe motility on follow up at 1 week, 1 month, 3 months, 6 months, and 12 months

Detailed Description:

Hypothesis: Polycaprolactone / Tricalcium Phosphate (PCL / TCP) Orbital Implant is as effective in the reconstruction of the Orbital walls as Titanium Mesh

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 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
