“…We established a baseline with a maximum accuracy error of < 2 mm, in line with literature standards for accuracy. This reference value ensures registration accuracy, a crucial aspect in maxillofacial surgery, achieved using dynamic reference frames (DRF) and stable maxillary anchorage markers, occasionally supplemented by mid-third anchorage markers [19].…”

(1) Introduction and Aim: Surgical navigation has evolved as a vital tool in maxillofacial surgery, offering precise and patient-specific data. This study explores the clinical applications and accuracy of intraoperative tool tracking in maxillofacial surgery. (2) Materials and Methods: The research includes 42 patients with various pathologies who underwent surgeries assisted by a surgical navigation system using tracked instruments. Four representative cases are exhibited in the study: the first case involving coronoid hyperplasia with mouth opening deficit, the second case addressing naso-orbital-ethmoidal-frontal ossifying fibroma resection, the third case showcasing a subapical osteotomy (Köle) for a class III dentoskeletal malocclusion, and the fourth one exposing the treatment of a recurrent ameloblastoma. (3) Results: The results indicate that surgical navigation with tracked instruments provides high precision (<1.5 mm error), reduced surgical time, and a less invasive approach. (4) Conclusions: This study highlights the potential for reproducible outcomes and increased safety, especially in complex cases. Despite some limitations, the synergy between surgical navigation and tracked instruments offers a promising approach in maxillofacial surgery, expanding its applications beyond current practices.

“…While there are many applications where surgical navigation can be implemented, these cases typically fall into two categories: monitoring actively moving instruments over time and guiding instruments to fixed locations. The former, common in applications of neurosurgery, demands systems to track surgeons' instrument movements (Pivazyan et al (2023)). The latter, common in applications of spinal surgery, necessitates systems guiding instruments precisely to specific points on the patient's body (Wallace et al (2020)).…”

Computer-assisted surgical navigation systems have gained popularity in surgical procedures that demand high amounts of precision. These systems aim to track the real-time positioning of surgical instruments in relation to anatomical structures. Typically, state-of-the-art methods involve tracking reflective 3D marker spheres affixed to both surgical instruments and patient anatomies with infrared cameras. However, these setups are expensive and financially impractical for small healthcare facilities. This study suggests that a fully optical navigation approach utilizing low-cost, off-the-shelf parts may become a viable alternative. We develop a stereoscopic camera setup, costing around $120, to track and monitor the translational movement of open-source based fiducial markers on a positioning platform. We evaluate the camera setup based on its reliability and accuracy. Using the optimal set of parameters, we were able to produce a root mean square error of 2 mm. These results demonstrate the feasibility of real-time, cost-effective surgical navigation using off-the-shelf optical cameras.

“…Nachdem die Techniken verfeinert waren, hat sich dieses System der computer- bzw. rechnergestützten Operationstechnik nachhaltig in der Wirbelsäulen- und Beckenchirurgie durchsetzen können [ 6 , 7 ]. Die Kollegen F. Zimmermann und J. Franke beleuchten den aktuellen Stand der Entwicklung dieser Techniken in Orthopädie und Unfallchirurgie.…”
