Frontofacial monobloc distraction using the StealthStation intraoperative navigation system: the ability to see where you are cutting.

Abstract: The frontofacial monobloc advancement is a safe,effective, and cosmetically acceptable treatment of frontal andmidface retrusions present in craniofacial syndromes. Although anumber of modifications have been put forward to supplement thisprocedure, the basic steps of cleaving the facial skeleton from theskull base remain the same. We present a case where intraoperativenavigation was used to visualize the craniofacial anatomy while thebone cuts were made for this cleaving process. This techniquevisually demonstrates parts of this procedure that were hithertoperformed solely using tactile and auditory inputs superimposed ona 3-dimensional model of the craniofacial anatomy in the surgeon’smind. This technique offers a significant advantage for teachingpurposes, in performing cases with complex anatomy and foraccurate positioning of the distractor devices.Key Words: StealthStation, intraoperative navigation, monoblocdistraction(J Craniofac Surg 2009;20: 00Y00) I t has been 30 years since Ortiz-Monasterio et al
