Between January 1996 and December 2001, 72 out of 354 patients were included in a retrospective study analysing the outcome of repaired orbital wall defects. Selection was dependent on the availability of pre and postoperative CT scans and on ophthalmologic examination. In particular, orthoptical assessment was performed up to 1 year after operation. In 72 patients, 83 orbital wall defects were analysed and allocated to one of five categories. Accuracy and type of reconstruction were assessed in unilateral orbital wall defects (n=61) and compared with functional outcome. Reconstruction was performed by using PDS membrane (39%), calvarian bone (13%), titanium mesh (7%) or a combination of these materials (37%). Postoperatively, 91% of the patients had normal vision without double images within 20 degrees at every gaze. Accuracy of reconstruction correlated with severity of orbital injury and functional outcome. Functional outcome between category II and III fractures showed no significant difference. The medial margin of the lateral infraorbital fissure being preserved (category II fracture) facilitates reconstruction technically. Accuracy of orbital reconstruction is one important factor to obtain best functional outcome, but other determinants like displacement and/or atrophy of intramuscular cone fat should be considered.
