“…We tried to enclose a large coronal plane between nose tip and nasion/superior orbital incisura in the rostrocaudal direction and a large axial plane with the frontozygomatic sutures and external acoustic meatus to minimize collinearity. Surgery mainly in the supine position for the frontal and temporal regions with the target in the close vicinity of the centroid of the NM helped to minimize the error [15].…”

“…▂ Es sind praktisch nur verschiebliche Weichteilstrukturen (des äußeren Ohres) als Referenzierungspunkte oder intraoperative Landmarken vorhanden. ▂ Die Navigation erfolgt in der Tiefe des Felsenbeins [20], weit entfernt von den Referenzierungspunkten. ▂ Es ist keine räumliche Staffelung der Referenzierungspunkte möglich [6,20].…”

“…▂ Die Navigation erfolgt in der Tiefe des Felsenbeins [20], weit entfernt von den Referenzierungspunkten. ▂ Es ist keine räumliche Staffelung der Referenzierungspunkte möglich [6,20]. ▂ Die Referenzierungspunkte sind äu-ßerst ungünstig verteilt [14], weil sie nicht über das gesamte abgebildete anatomische Areal verteilt sind [15,21].…”

“…The point-based registration method computes a transformation matrix on the basis of at least three paired points between the patient and the image. Skin-affixed markers, anatomic landmarks, or both are commonly used to determine the paired points [3,4]. Surgeons are required to specify the positions of the paired points and feed this information into the system for calculation of the transformation matrix.…”
