“…The surgeon can now see two lines coinciding in all three planes (sagittal, coronal and axial). 8 , 9 This verifies the correct plane of dissection. During reconstructive surgery or where implant placement is needed, the final check is carried out after implant placement and before fixation.…”

Surgeries related to the maxillofacial area deal with an intricate network of anatomical structures. With the complexity of the vital structures, it necessitates a surgical team to respect each anatomical boundary. In the past, there was an exceptionally high number of cases with surgical errors. These errors were not because of flaws in the surgeon’s skills or techniques but owing to lack of resources. Visualisation is one of the key factors that determines the precision of any surgical outcome. Advances in surgical planning have led to the introduction of a “Navigation” system that helps surgeons to see more, know more and ultimately do more for their patients. The usefulness of the navigation system in oral surgeries has been indicated by its surgical applications in craniomaxillofacial trauma, orthognathic surgeries, head and neck pathological resections, complex skull base surgeries and surgery involving temporomandibular joint. A vast majority of research literature has suggested remarkable improvement in surgical outcomes under the guidance of 3d planning and navigation. However, with such an inordinate advancement, financial expenses and a gradual learning curve are always a constraining factor in surgical navigation. This article overviews indication of navigation in craniofacial surgeries with a focus on applied aspect, planning and solution to the future problem.

“…In this double center clinical trial, we systematically evaluated the efficacy of our navigation system and experience in craniomaxillofacial navigation surgery. Previous studies showed that image-guided navigation had many potential applications in oral and craniomaxillofacial surgery, including localization of pathological lesions or foreign bodies, fracture reduction, gap arthroplasty for the temporomandibular joint ankylosis, orthognathic surgery, jaw tumor resection, and surgical corrections of craniomaxillofacial malformations or facial asymmetries 1 2 11 12 18 19 . In this study, we systematically confirmed these indications and mandible distraction osteogenesis.…”

“…Precise reconstruction or correction of those defects/deformities remains a surgical challenge. With the development of modern digital surgery technology, computer-assisted simulation and navigation (CASN) has been described as a useful strategy for clinical application1234. In oral and craniomaxillofacial surgery, navigation technology has been reported in numerous applications, including removal of foreign bodies, bony tumor resection, reduction of the fractures, deformity correction, defect reconstruction and gap arthroplasty for the temporomandibular joint ankylosis15678.…”

Numerous problems regarding craniomaxillofacial navigation surgery are not well understood. In this study, we performed a double-center clinical study to quantitatively evaluate the characteristics of our navigation system and experience in craniomaxillofacial navigation surgery. Fifty-six patients with craniomaxillofacial disease were included and randomly divided into experimental (using our AccuNavi-A system) and control (using Strker system) groups to compare the surgical effects. The results revealed that the average pre-operative planning time was 32.32 mins vs 29.74 mins between the experimental and control group, respectively (p > 0.05). The average operative time was 295.61 mins vs 233.56 mins (p > 0.05). The point registration orientation accuracy was 0.83 mm vs 0.92 mm. The maximal average preoperative navigation orientation accuracy was 1.03 mm vs 1.17 mm. The maximal average persistent navigation orientation accuracy was 1.15 mm vs 0.09 mm. The maximal average navigation orientation accuracy after registration recovery was 1.15 mm vs 1.39 mm between the experimental and control group. All patients healed, and their function and profile improved. These findings demonstrate that although surgeons should consider the patients’ time and monetary costs, our qualified navigation surgery system and experience could offer an accurate guide during a variety of craniomaxillofacial surgeries.

“…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.…”
