A method of maintaining patient registration in surgical navigation includes:obtaining a patient position in a tracking system frame of reference, based onafiducial marker array affixed in a first position relative to the patient；receiving aninitial surface scan depicting the patient and the fiducial array； responsivetoreceiving an intraoperative image depicting the patient: obtaining a position,inthe tracking system frame of reference, of the fiducial array affixed in asecondposition relative to the patient； receiving a secondary surface scan depictingthepatient and the fiducial array； detecting a deviation in a position of thefiducialmarker array relative to the patient between the initial and secondary surfacescans； and applying the deviation to the position of the patient to generateanupdated position of the patient in the tracking system frame of reference,basedon the fiducial array affixed in the second position.
