Comparison of 3 Optical Navigation Systems for Computer-Aided Maxillofacial Surgery

An integrated orthognathic surgery system for virtual planning and image-guided transfer without intermediate splint

“…In this imageguided surgery, the target deviation error was 1.1 ± 0.91 for 3D bone segment positioning (Chapuis et al, 2007). Other previous studies on surgery guidance systems reported a target registration error ranging from 1.13 mm to 3.79 mm (Benardete et al, 2001;Eggers et al, 2009;Metzger et al, 2007;Seeberger et al, 2012;Strong et al, 2008;Zhang et al, 2011Zhang et al, , 2012.…”

Virtual skeletal complex model- and landmark-guided orthognathic surgery system

“…A surgical navigation tracking system has been used in the craniomaxillofacial area (Nijmeh et al, 2005;Strong et al, 2008;Eggers et al, 2009;Zhang et al, 2011Zhang et al, , 2012Seeberger et al, 2012;Kim et al, 2014;Li et al, 2014). Intraoperative navigation based on optical tracking system requires no radiation equipment but has some technique-based inaccuracy (Mascott, 2005).…”

“…Surgical navigation systems are commonly used in the craniomaxillofacial area to overcome the disadvantages of conventional methods (Nijmeh et al, 2005;Strong et al, 2008;Eggers et al, 2009;Zhang et al, 2011Zhang et al, , 2012Seeberger et al, 2012;Kim et al, 2014;Li et al, 2014;Bobek, 2014). Generally, the navigational surgery method consists of patient computed tomographic (CT) imaging, preoperative planning, and transfer of the plan to the patient.…”

Comparison of virtual and titanium clip marking of tumour resection margins for improved radiation planning in head and neck cancer surgery

“…To allow movement of the patient's head during surgery and while using intraoperative navigation, a reference sensor has to be attached to the patient. The optical reference sensor is invasively secured to 20 Metzger et al evaluated four different CAS registration strategies in the maxillofacial skeleton and concluded that invasive fiducial markers are the most accurate. Skin surface landmarks, bony landmarks, and intraoral splints provide a registration error between 2.0 and 3.8 mm.…”
