Abstract:
PURPOSE: To investigate the effects of anterior displacement of four rectus muscles in exposure of porous polyethylene orbital implant (Medpor(R)). CASE SUMMARY: This retrospective study reviewed 4 eyes with exposed orbital implant who underwent evisceration with porous polyethylene orbital implant (Medpor(R)). The technique involves dissection of conjunctiva and tenon's capsule and isolation of four rectus muscles from sclera. Unsure if each muscle was sutured to each other or if a group of muscles were sutured to another group (i.e. superior and inferior to medial and lateral). Posterior tenon's capsule was closed interruptedly and conjunctiva was closed continuously. Orbital implant exposure was occurred at 2~36 months later after evisceration and implant insertion. One eye was noted wound dehiscence 1 week after operation, then re-suture was done. Re-exposure was notified in 1 eye at postoperative 3 months, but it was small, then we just observed. In other 3 cases, exposure was not identified till last follow up. CONCLUSIONS: Four rectus muscle anterior displacement procedure may be simple and useful method in exposure of orbital implant.
