Surgical treatment of posttraumatic enophthalmos with diced medpor implants through mini-lateral canthoplasty incision.

High-density porous polyethylene (Medpor Surgical Implants, College Park, GA) enophthalmic implants are used in patients with sunken socket syndrome to augment the orbital volume. A transconjunctival or subciliary approach is used to access the orbital floor. We present a new approach for accessing the orbital floor using diced Medpor implants through a mini-lateral canthoplasty incision. Medpor particles diced about 1 x 1-cm diameter were inserted through alateral canthal incision to orbital floor. The advantages of this technique are limited incision, decreased postoperative edema, volumetric adjustability, and applicability under local anesthesia. Three cases with blow-out and neglected zygomaticomaxillary fractures underwent primary or secondary diced Medpor orbital implantation. No cases showed any implantial infection. Our preliminary results showed no complication, and this novel method seems to have no severe disadvantage in the surgical treatment of posttraumatic enophthalmos.
