Treatment of Exposed Hydroxyapatite Orbital Implant Using Acellular Dermal Allograft

ABSTRACT

PURPOSE: To investigate the results of acellular dermal allograft (SureDerm(R), Hans Biomed Co., Korea) as a new covering material in the exposure of hydroxyapatite orbital implant. METHODS: SureDerm graft was performed in 5 patients with exposed hydroxyapatite orbital implant. Under local anesthesia, the anterior surface of the exposed implant was trimmed and the designed SureDerm was sutured at the margin of the sclera with 6-0 Vicryl. Finally, conjunctival suture was done. The patients were followed up regularly until postoperative 10 months. RESULTS: The average diameter of exposed implant was 9.6 X 9.0 mm. The grafted SureDerm had survived in all patients at postoperative 10 months and exposure of implant was treated successfully in all cases. CONCLUSIONS: We consider that acellular dermal allograft will be a good replacing material when preserved sclera is not available. It also features the advantage of avoiding the intricate harvesting procedure and the scarring of the donor site in dermo-fat graft.
