Three renowned doctors at the Corneo Plastic Unit of Queen Victoria Hospital in East Grinstead, United Kingdom recently finished conducting an Institutional Review Board (IRB) approved three-year long facial paralysis treatment study.
The purpose of the study was to cosmetically compare gold weights and platinum chains. Outcomes compared eyelid measurements, cosmesis, and complications.
A retrospective review over a three-year period identified 42 primary gold weights and 17 primary platinum chain insertions in patients who could be matched for pathology, laterality, and weight of implant. The study was approved by the IRB.
- Gold weights demonstrated an improvement in eyelid parameters.
- Platinum chain improved eyelid measurements.
- Mild eyelid prominence was noted in a couple of cases.
- Eyelid contour remained normal in all patients.
- No complications were noted with either gold weight or the platinum chain implants.
The gold weights, by the nature of its design, sit prominently within the eyelid. Platinum, an alternative metal to gold, is denser and takes up less volume within the eyelid.
Both devices were successful in treating complications of lagophthalmos. Cosmesis is clearly defined in terms of eyelid prominence and contour. Platinum chains appear less prominent and maintain normal eyelid contour. Although more expensive, platinum chains appear to be as safe and effective as gold weights, yet provide better cosmesis.
This study was retrospective with small numbers, meaning definite conclusions cannot be drawn from the data set. Further studies are needed to guarantee these conclusions.
