A novel device for preoperative registration and automatic tracking in cranio-maxillofacial image guided surgery

Abstract

By successfully addressing the two key issues of image guided surgery, the device could be considered accurate and potentially useful for assisting in cranio-maxillofacial surgery.

Validation of a fibula graft cutting guide for mandibular reconstruction: experiment with rapid prototyping mandible model

“…Further studies should investigate various error factors to determine how to modify the method for clinical applications with the use of various surgical guides, and for integration with an auxiliary navigation method. [9][10][11] In conclusion, our results are based on experiments with RP models of mandibles and fibulas. These RP mandibles were reconstructed with fibulas that were cut with either a surgical template guide or a manual method.…”

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.…”

Registration using 3D-printed rigid templates outperforms manually scanned surface matching in image-guided temporal bone surgery

“…An autoregistration device using a malleable adhesive mask with LED markers for the face [24,25] is another noninvasive method that shares a similar theoretical background with the S-STAMP method. Template-based registration using the upper dentition can be applied with minimal invasiveness and serviceable accuracy at the paranasal sinus [26]; however, this registration method did not provide satisfactory accuracy at the lateral skull base [16,27]. The problem lies in the distance from the upper teeth (registration centroid) to the temporal bone, resulting in a larger error [28].…”
