Burnishing of exposed porous polyethylene orbital implant: is it useful?
|
| Abstract | OBJECTIVE: To describe and report the surgical outcomes of the burnishing technique for exposed porous polyethylene (PP) orbital implants. METHODS: A retrospective review of consecutive patients who underwent repair of an exposed PP orbital implant at Hong Kong Eye Hospital and Queen Elizabeth Hospital, Hong Kong, between January 2002 and April 2022 was conducted. Exposed PP orbital implants were burnished with an electric drill. The exposed area was then covered by a donor scleral graft followed by conjunctival wound closure. Patients with a shallow lower eyelid fornix would undergo additional fornix deepening procedures that mobilize the conjunctiva and provide adequate coverage of the implant. RESULTS: Six patients who had exposed PP orbital implants following enucleation (n = 4) and evisceration (n = 2) underwent repair. Five of the six patients did not experience any recurrence at an average follow-up of 25 months (range, 7-42 months). One patient who suffered from endophthalmitis experienced orbital implant re-exposure 16 months after the revision was managed by reimplantation of an acrylic implant and wrapping with both donor scleral graft and dermis fat graft. CONCLUSION: In conclusion, we described a burnishing technique for repairing exposed PP orbital implants. Our technique is effective in preventing implant re-exposure and is easy to perform.
