BACKGROUND: Many reconstruction materials for orbital floor @entity174 have been described in the past including autologous bone transplants, resorbable polymers and titan meshes. So far evidence is missing which material is used successfully regarding indication and particular size of defect. Therefore the aim of this study was to evaluate which reconstruction technique produces best clinical outcome and least complications associated with indication. METHODS: Retrospectively, surgical and ophthalmological data plus CT scans from a collective of 775 @entity1 between 2005 and 2012 were analyzed. Furthermore included @entity1 were sounded on satisfaction and potential problems postoperatively. RESULTS: Overall 593 @entity1 offered full pre- and postoperative short-time data appropriate to inclusion criteria - of these 507 (85,5  %) underwent primary surgical treatment. Smallest average defect size was found in cases with no indication for surgical treatment (81  mm(2)), largest in cases indicating @entity702 mesh reconstruction (601.5  mm(2)). In 15 cases exact fragment reposition was possible without insertion of alloplastic material. Best clinical results obtained reconstruction using @entity16265 foil ( @entity1480 ). 0.15  mm @entity1480 -foil: 444 @entity1 , reduced @entity892 pre to postoperative 16 to 6  % (p   <   0.01), ex- and enophthalmus   <   2  % after surgery. 0.25  mm @entity1480 -foil: 26 @entity1 , reduced @entity892 from pre- to postoperative 34,6 to 3,8  % (p   <   0.01), postoperative exophthalmus rate was higher than preoperative (3,8 to 7,7  %). In comparison to reconstruction with @entity1480 -foil a higher percentage of @entity1 reconstructed with @entity702 meshes (n   =   22) revealed no significant reduction of @entity892 (45,5 to 31,8  %; p   =   0.07). Furthermore 63 of all included @entity1 agreed to complete a questionnaire on intermediate-term postoperative symptoms and surgical contentedness. Remarkably 50  % of the @entity1 reconstructed with @entity702 meshes indicated @entity1109 and cold feeling in the long-term. CONCLUSIONS: Short- and intermediate-term results of clinical outcome in our @entity1 with surgical treated orbital floor @entity174 (i.e. @entity892 , en- or exophthalmus) reveal that thin resorbable foils, particularly 0.15  mm diameter @entity1480 -foil seem to generate best results referring to orbital floor defects with a size of 250 to 300  mm(2). TRIAL REGISTRATION: Study number 4222, year 2013, ethics committee of the medical faculty of the Heinrich Heine university of Duesseldorf.
