First, it is done on the sound side with the dial tension
gauge to allow comparisons to be made, because the gauge
can record tension as a red indicator. The opposite side is
then tested. The orbital fracture is then repaired through the
endoscopic transantral approach and improvement of ocular
movement is re-assessed with the dial tension gauge. When
ocular movement cannot be improved through the endoscopic
transantral approach, the conventional approach is
used.
