“…VSP is increasingly applied especially in two or more segmented mandible reconstruction cases to facilitate osteotomies and thus enhance accuracy. Several authors describe advantages of this method regarding reduced operating time and increased precision of reconstruction with comparable complication rates [2,4,[9][10][11][12][13][14][15][16][17]. Critical points are the additional costs and time for preoperative planning and that the strategy is superfluous in the case of positive margins or other reasons for intraoperative treatment concept modification [18][19][20].…”

Objectives Mandibular reconstruction after segmental mandibulectomy can be challenging without virtual surgical planning and osteotomy guides. The purpose of this study was to analyze anatomic parameters to facilitate the evaluation of ideal fibula wedge osteotomies to reconstruct the neomandibula in a simple and cost-effective manner without the need for preoperative virtual planning. Materials and methods Computed tomography scans were acquired from randomly selected patients, and all images were obtained from routine clinical diagnostics, e.g., tumor staging, or preoperatively before reconstruction. Data was used to calculate stereolithographic models of the mandible for length and angle measurements. Statistical analysis was performed (p < 0.05). Results CT scans of 100 patients were analyzed: 39 were female and 61 were male patients, mean age was 59.08a. The mandibular arch angle proved to be constant with 241.07 ± 2.39°. The outside B-segment length was 80.05 ± 5.16 mm; the anterior S-segment length was 27.69 ± 3.16 mm. The angle of the mandibular arch showed differences in means (p = 0.004) between age groups, but effect was proved low. No relevant statistical significances were detected. Conclusions The development of a mandible reconstruction template tool would benefit the majority of head and neck patients, which is due to a constant mandibular arch angle and symphysis segment length throughout the general patient population, allowing the mimicking of a harmonic mandibular arch with up to three fibula segments. Clinical relevance The developed mandible reconstruction template tool can facilitate the fibula wedge osteotomies necessary for reconstruction of an ideal neomandibula providing a novel approach which is simple and cost-effective.

“…Unfortunately, however, positioning a fibula segment in the mandible is more difficult during an actual reconstruction surgery than it is in the surgical simulation. Methods for placing the fibula bone segments into mandibular reconstruction sites have been reported previously [ 6 , 7 ]. Fibula segments can be fixed with plates of various sizes and materials, including metal reconstructive plates, mini plates, or resorbable plates.…”

Precision of fibula positioning guide in mandibular reconstruction with a fibula graft

BackgroundThis study examined the usefulness of the fibula positioning guide for boosting the accuracy of mandible reconstructions.MethodsThirty mandibular rapid prototype (RP) models were allocated to experimental (N = 15) and control (N = 15) groups. For reference, we prepared a reconstructed mandibular RP model with a three-dimensional printer, based on surgical simulation. In the experimental group, a fibula positioning guide template and fibula cutting guide, based on simulation, were used to reconstruct the mandible with a fibula graft. In the control group, only the fibula cutting guide, with reference to the reconstructed RP mandible model, was used to reconstruct the mandible with a fibula graft. The two mandibular reconstructions were compared to the surgical simulation by registering images with the non-surgical right side of the mandible. On the reconstructed side, 3D measurements were compared between the surgical simulation and actual surgery, and the sum of differences was taken as the total error.ResultsThe combined use of the fibula cutting and positioning guides produced a smaller total error (mean ± SD: 10.0 ± 7.9 mm) than the fibula cutting guide alone (12.8 ± 8.8 mm; p = 0.015). The greatest point error was the vertical error at the mesial point of the anterior fibula segment. The anteroposterior and lateral errors were not significantly different between groups. These results showed that these two methods were not significantly different, except in the total and vertical errors.ConclusionsConsidering the CAD/CAM processes required for creating positioning devices, the benefit provided with a positioning guide justified its use over the fibula cutting guide alone.
