Early surgical intervention for orbital floor fractures: a clinical evaluation of lyophilized dura and cartilage reconstruction.

Experience in the management of 77 isolated orbital floor fractures is presented. The transconjunctival approach was used exclusively to access the orbital floor and lyophilized dura and cartilage were used to reconstruct the floor, when indicated. Follow-up for an average of 36 months showed excellent cosmetic and functional results. A 20% complication rate was noted, which compares favorably with what is reported in the literature. There were no graft extrusions or infections and only one case of graft displacement. These findings support the concept of early treatment of orbital floor fractures, even in "minimally symptomatic" patients. Lyophilized dura and cartilage proved to be safe and effective materials for orbital reconstruction.
