Abstract
Purpose
To investigate the clinical results of patients who have undergone simultaneous dermofat graft and insertion of orbital implants in patients who are unable to put on an ocular prosthesis due to severe conjunctival sac contracture or large orbital implant exposure.
Methods
A retrospective analysis was performed of patients who underwent dermofat graft simultaneously with orbital implant insertion for replacement of the conjunctival sac from 2007 to 2012. Eight eyes were enrolled in this study and all patients were followed up for phthisis bulbi or implant exposure.
Results
Among the eight eyes, five eyes (62.5%) that were diagnosed with orbital implant exposure underwent orbital implant exchange and dermofat graft, and two eyes (25%) were anophthalmic enophthalmic patients and underwent secondary orbital implant insertion and dermofat graft. One patient (12.5%) underwent orbital implant insertion and dermofat graft simultaneously during the evisceration operation. We followed the progress for 46.3 months.
For seven out of eight eyes, the results of the wound healing process were successful. One patient underwent removal and reinsertion of the orbital implant with dermofat graft, and the wound in this case healed well. However, after five months, dermofat regraft was performed for orbital implant reexposure and it was not exposed thereafter. Overall cosmetic appearance was satisfactory in each patient, and all patients were able to comfortably retain a prosthesis.
