Counteracting paradoxical motion in videoendoscopic operations.
Paradoxical motion during videoendoscopic operations is generated when the camera and instruments are on opposite sides of the targeted pathology. This is occasionally difficult to avoid when operating on a wide field. We have found that turning the camera 180 degrees restores the normal spatial relationship. This simple maneuver allows the operator to use the existing camera and instrument ports to his or her best ergonomic advantage.
