A medtronic ent representative reported that, while in a functional endoscopic sinus surgery (fess) the surgeon alleged the balloon dialator was tracking slightly anterior of its actual position.The surgeon had the balloon inside the frontal sinus and was touching bone, however, images showed being slightly inside the bone.No trouble-shooting was performed as the surgeon deemed the inaccuracy was insignificant enough to continue navigating the balloon as intended.The surgeon completed the procedure with the use of the navigation system.There was no impact on patient outcome.
