Abstract

BACKGROUND AND OBJECTIVES
Enophthalmos is a common sequelae of orbital fracture. Moreover, it is difficult to treat secondarily. We assessed the effect of filling up the orbital volume defect with implants on the correction of late posttraumatic enophthalmos.
SUBJECTS AND METHOD
Based on patients' clinical data, we retrospectively reviewed 11 patients who had an operation because of late posttraumatic enophthalmos from July 2001 to December 2005. To correct late posttraumatic enophthalmos, porous polyethylene (Medpor(R)), Medpor(R) enophthalmos wedge implant, absorbable mesh, bone graft particulate, rib cartilage, auricle cartilage, and maxilla anterior wall were used.
RESULTS
Among 11 patients, 6 patients were men and 5 patients were women. The average age was 33.2 years with the follow-up period of 21.8 months. Five patients had orbital floor fracture, 1 patients had medial orbital wall fracture, 4 patients had a combination of orbital floor and medial orbital wall fractures, and 3 patients had zygoma fracture. Excellent results were obtained in all 5 patients with diplopia. The amount of enophthalmos corrected was between 1 and 5 mm (mean 2.5 mm). There was no case of visual loss, infection, migration, or exposure of implant, but we carried out re-operation on 1 case due to over reduction.
CONCLUSION
Filling up the volume defect with proper implants is a relatively simple, safe and efficient technique in correcting late posttraumatic enophthalmos.
