Three-Dimensional Surgical Planning in Mandibular Cancer: A Decade of Clinical Experience and Outcomes

Simple Summary Cancer of the mouth often requires removal of part of the jaw. Dutch guidelines recommend surgical treatment within 30 days and the achievement of tumor-free bone margins of >5 mm. Three-dimensional virtual surgical planning has become standard practice in treatment planning as it improves accuracy and predictability of resection and reconstruction. Resections are performed using resection guides, followed by reconstruction with either hand-bent plates or 3D-designed implants. This study evaluates guideline adherence, plate-related complications, and the accuracy of 3D-planned mandibular resection and reconstruction using different osteosynthesis plates. The median time to surgery in this cohort slightly exceeded the guideline recommendations, and a high percentage of bone margins were tumor-free. Bridging the mandibular gap with just a reconstruction plate showed higher plate-related complications compared to reconstructions in which bone could be inserted. Resection was performed with high accuracy. Reconstructions with 3D-designed implants were more accurate in selected dimensions than conventional plates.
