Objective:
To determine the efficiency (and accuracy) of endoscopic repair versus transconjunctival repair for orbital floor fractures in a cadaveric model.
Methods:
In nine fresh cadavers, a standardized technique created orbital floor fractures. One orbit was repaired using an endoscopic transantral approach, whereas the other was repaired using a standard transconjunctival approach. Commercially available implants were used for floor reconstruction. A validated computed tomographic volumetric analysis of the orbits was performed at three time points: prefracture, postfracture, and postrepair. Student's t-test analyzed the percentage of volume change in the prefracture and postrepair stages for each approach.
Results:
The percentage of change between the prefracture and postrepair states was not statistically significant for transconjunctival (p = .834) or endoscopic (p = .366) repair. The average differences between transconjunctival repair and endoscopic repair were not statistically significant (p = .732).
Conclusions:
This study objectively confirms the efficiency of the endoscopic repair of orbital floor fractures when compared with traditional techniques in the cadaveric model.
