“…However, these studies neglected the factors involving intra-orbital soft tissue. In some delayed or severe orbital fracture cases, even if the orbital bony structure is anatomically reconstructed, various degrees of enophthalmos can remain after surgery [18–20]. …”

BackgroundThe aim of the present study was to establish the normal-range orbital parameters and to explore the relationships between ocular protrusion and various orbital morphological factors.Material/MethodsA retrospective, non-comparative case series was conducted from January 2014 to December 2015. We recruited 56 subjects (112 orbits), including 27 males (21 to 87 years of age) and 29 females (22 to 88 years of age) in this study. Nine length measurements, 2 angle measurements, and 2 volume measurements of various aspects of the orbit were obtained using Mimics v18.0 software. The data were collected manually using a 3D measurement technique. Statistical analyses using t tests and Pearson’s correlation analyses were performed to evaluate the differences and relationships between the parameters, respectively.ResultsOcular protrusion in both sexes was closely related to the following values: orbital soft tissue volume (OSTV) (males: r=0.61, p<0.001; females: r=0.39, p=0.003), orbital soft tissue volume/bony orbital volume (OSTV/BOV) (males: r=0.90, p<0.001; females: r=0.87, p<0.001), orbital width (males: r=0.40, p=0.003; females: r=0.53, p<0.001), orbital height (males: r=0.29, p=0.038; females: r=0.45, p<0.001), and globe diameter (males: r=0.52, p<0.001; females: r=0.48, p<0.001). No differences were found between the right and left orbits.ConclusionsThe study provides insight into the potential factors that influence ocular protrusion, which include the OSTV/BOV ratio, the shape of the orbital aperture, and the ocular axial length. The results of orbital surgery can be made more predictable by accounting for these 3 factors. The database and regression formula might provide support for surgical planning in the future.

“…Surgical navigation is the most commonly used technique, and its indications in craniofacial surgery generally involve trauma, [1][2][3][4] orthognathic surgery, [5][6][7] surgical oncology, [8][9][10] temporomandibular joint (TMJ), 11,12 and reconstructive surgery. [13][14][15] Most of the available literature regarding surgical navigation in the craniofacial field regards a simple description of an application of this technology in a particular clinical setting, such as the use of navigation for foreign body removal, implant positioning, prosthetic placement, orbital reconstruction, or tumor resection, often without an organic description of the actual accuracy of the technique.…”

Objective Computer‐assisted planning of osteotomy lines, coupled with navigation‐guided performance of planned osteotomies, is a highly innovative approach to skull‐base and orbital surgery. The aim of this pilot study is to provide an assessment of the accuracy of this novel approach in guiding the correct positioning of osteotomy lines in frontal, temporal, and orbital regions, defining the agreement between the spatial position of the planned and performed osteotomies. Methods Fifteen patients with orbital, frontal sinus, and lateral skull‐base diseases underwent virtual surgical planning. Osteotomies to access the orbit, frontal sinus, and lateral skull base were planned on computer tomography‐based three‐dimensional models. The planned osteotomies were reproduced on the operating field using a navigation system. The positions of the performed and planned osteotomies were compared. The results were described as the mean positional difference between planned and performed osteotomies and as Lin's concordance coefficient, and Bland‐Altman limits of agreement were also defined. Results The overall mean difference was 0.719 mm (95% confidence interval [CI]: 0.472 to 0.965 mm). Overall, Lin's concordance coefficient was 0.997 (95% CI: 0.996 to 0.998), and overall Bland‐Altman limits of agreement ranged from −1.407 to 2.844 mm. The smallest mean difference (0.587 mm, 95% CI: 0.244 to 0.931 mm) was calculated in the orbit group, whereas the highest mean difference (0.904 mm, 95% CI: 0.428 to 1.379 mm) was described in the lateral skull‐base group. Conclusion This study's results support the use of this novel planning and navigation protocol for guiding osteotomy in anterior and lateral skull‐base surgery, providing a clinical validation of this technique.

“…For secondary facial bone reductions, combining surgical navigation with high-resolution computed tomography (CT) imaging and CAD/CAM is helpful. These technologies are beneficial for preoperative planning, guiding surgical instruments, and evaluating surgical results [8][9][10][11]. These procedures can be summarized as follows: (1) acquiring preoperative image data from patients and performing preoperative simulation; (2) using the planning results to monitor and assist in reduction surgery; and (3) evaluating intraoperative or postoperative results.…”

“…In these situations, the predetermined surface marks or screw holes on the bone serve as navigation reference points. Operators can use a DRFmounted probe to check whether the mark positions are in good alignment with the presurgical plan [11,12].…”
