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.

Purpose We present a case of orbital abscess following porous orbital implant infection in a 73-year-old woman with rheumatoid arthritis. Methods Just one month after a seemingly uncomplicated enucleation and porous polyethylene (Medpor®) orbital implant surgery, implant exposure developed with profuse pus discharge. The patient was unresponsive to implant removal and MRI confirmed the presence of an orbital pus pocket. Despite extirpation of the four rectus muscles, inflammatory granulation debridement and abscess drainage, another new pus pocket developed. Results After partial orbital exenteration, the wound finally healed well without any additional abscess formation. Conclusions A patient who has risk factors for delayed wound healing must be examined thoroughly and extreme care such as exenteration must be taken if there is persistent infection.
