“…Stereotactic navigation is another technology that is particularly useful when operating in the midface, not only to extirpative surgeons. Navigation systems were initially developed for use in neurosurgery and are now commonly used in craniomaxillofacial surgery because of the reliability and an accuracy of less than 1 to 2 mm . In reconstruction, it can be used to ensure that free flaps and bone grafts are positioned appropriately in 3‐D space, particularly with limited incisions .…”

Reconstructive technologies have expanded to include the use of virtual surgical planning (VSP) and computer-aided design and manufacturing (CAD-CAM), and 3-Dimensional printing. The advantages of VSP over traditional techniques are highlighted in many scenarios: (a) delayed reconstruction, (b) maxillary reconstruction, (c) placement of dental implants, and (d) precision guided oncology. Microsurgery is undergoing a paradigm shift with virtual planning at its foreground. Herein, we describe the versatile uses for CAD-CAM and key operative steps.

“…Second, the range of CT images during navigation is generally wide. Registration techniques can be categorized into two main groups: marker-based and marker-free [5]. Marker-free registration relies on the patient’s craniofacial anatomy.…”

“…Computer-assisted navigation systems have recently evolved to simplify and improve the precision of the surgical procedure to minimize surgical invasiveness. Therefore, the execution and predictability of surgical procedures has improved, allowing for more precision during maxillofacial surgery [5]. Complications such as registration and deterioration of accuracy are important issues during intraoperative navigation.…”

Background Oral and maxillofacial surgeons often encounter foreign objects within the human body. Despite the visual identification of foreign objects via imaging techniques, the accurate determination of their position in the maxillofacial area can be challenging. The clinical application of a navigation system can solve this issue. This system provides a useful guide for a safer and more accurate surgical technique by accurately determining the location of the lesion in real time during the surgery. However, complications with regard to registration may be encountered. We describe a navigation system that simplifies registration using a dental splint with embedded reference points for foreign body removal in the maxilla. Case presentation A 78-year-old Japanese woman was referred with the chief complaint of pain in the left upper molar region. We found the symptoms to be associated with a foreign body in the maxilla and decided to remove it. A minimally invasive treatment procedure was desirable. However, the lesion was in contact with the maxillary sinus, and it was difficult to pinpoint its position because of the absence of an anatomical landmark. Therefore, we decided to use a navigation system. In order to simplify registration, a dental splint with embedded reference points was created. The registration could be reliably performed before surgery using an optical navigation system that facilitates the process, using splints with embedded reference points. Following preoperative registration, the splint with the reference frame was placed in the patient’s mouth, and the accuracy of the navigation was confirmed. The position with respect to the maxillary sinus was precisely identified followed by the removal of the surrounding bone and excision of the lesion. Therefore, the surgery could be accurately performed without perforating the maxillary sinus. In addition, owing to preoperative registration, the operative time could be shortened. After the surgical procedure, the patient’s symptoms disappeared. Conclusions The procedure was performed in a precise, minimally invasive manner. Furthermore, the operative time was reduced by the simplified registration process, wherein a splint was embedded with reference points. This technique may prove useful for performing maxillofacial surgical procedures.

“…The prevalence of OWF has been reported to be 18%–50% in all cases of craniomaxillofacial trauma. 1 , 2 , 3 Safe, rapid and precise reconstruction of the orbital wall is essential for restoring normal function and esthetics, but repair is hampered due to limited surgical exposure and complicated three-dimensional (3D) anatomic structures. Also, the reconstruction outcome is unpredictable because of soft-tissue edema, broken contours of the orbital wall, and difficulty of positioning the implant appropriately.…”

Purpose To evaluate the outcomes with and without aid of a computer-assisted surgical navigation system (CASNS) for treatment of unilateral orbital wall fracture (OWF). Methods Patients who came to our hospital for repairing unilateral traumatic OWF from 2014 to 2017 were included in this study. The patients were divided into the navigation group who accepted orbital wall reconstruction aided by CASNS and the conventional group. We evaluated the surgical precision in the navigation group by analyzing the difference between actual postoperative computed tomography data and preoperative virtual surgical plan through color order ratios. We also compared the duration of surgery, enophthalmos correction, restoration of orbital volumes, and improvement of clinical symptoms in both groups systemically. Quantitative data were presented as mean ± SD. Significance was determined by the two-sample t -test using SPSS Version 19.0 A p < 0.05 was considered statistically significant. Results Seventy patients with unilateral OWF were included in the study cohort. The mean difference between preoperative virtual planning and actual reconstruction outcome was (0.869 ± 0.472) mm, which means the reconstruction result could match the navigation planning accurately. The mean duration of surgery in the navigation group was shorter than it is in the control group, but not significantly. Discrepancies between the reconstructed and unaffected orbital-cavity volume and eyeball projection in the navigation group were significantly less than that in the conventional group. One patient had remnant diplopia and two patients had enophthalmos after surgery in the navigation group; two patients had postoperative diplopia and four patients had postoperative enophthalmos in the conventional group. Conclusion Compare with the conventional treatment for OWF, the use of CASNS can provide a significantly better surgical precision, greater improvements in orbital-cavity volume and eyeball projection, and better clinical results, without increasing the duration of surgery.
