Wrapping of Porous Orbital Implant Using Acellular Dermal Allograft

Purpose: To investigate the results when using the acellular dermal allograft (SureDermⓇ, Hans Biomed Co., Korea) as a new wrapping material for porous orbital implants. Methods: The charts of 11 patients who underwent either primary or secondary insertion of MedporⓇ orbital implants after enucleation or a new insertion after removal of previous orbital implants were reviewed. MedporⓇ orbital implants either 18 or 20 mm were wrapped with SureDermⓇ in 4×4 cm sections that were 1-mm-thick. Four rectus muscles were fixed to the SureDermⓇ wrapped implant, and a conjunctival suture was made with 6-0 Vicryl. All patients had follow-up periods longer than 10 months and were evaluated to determine the success of wrapping and to identify any complications. Results: The average age of the patients was 48.3 years. The patients wore artificial eyes for 9 weeks after the operation, and the follow-up periods were 22.4 months on average. There was no case of implant or SureDermⓇ exposure, inflammation, and other significant complications except in one case that required fornix reconstruction to allow the subject to wear an artificial eye. Conclusions: Acellular dermal allograft appears to be a good substitute material if preserved sclera is not available when inserting orbital implants with wrapping.
