Purpose: With the increasing number of patients suffering from various kinds of trauma, reconstruction of orbital-zygomatic-maxillary (OZM) fracture is turning out to be a challenge. This study is aimed to investigate the surgical technique and operative effect of late reconstruction of OZM fractures accompanied by symptoms of enophthalmos.

Methods: Retrospective analysis of the 50 patients (50 orbits) who were treated from January 2005 to December 2008. All cases had late reconstruction of OZM fractures on average 4.6 months after injury. Various incisions were selected. According to the CAD/CAM design, the osteotomy, reposition and four-point fixation of the fractured bones were individually performed. Titanium mesh was preshaped according to the mirroring-technology and inserted into the orbit to repair the orbital wall defect and the enlarged orbital volume. All patients were followed up 1 year after surgery.

Results:45 out of the 50 patients who suffered from enophthalmos have been completely corrected. 42 patients who suffered from hypoglobus were corrected post-operation. Of the 44 cases with diplopia, 20 cases were resolved. Of the 37 cases with restricted globe movement, there were 18 cases of recovery. No complications had been observed.
