“… 7 Such prostheses had an average postoperative deviation of the condyle from the preoperative position of 3.8 mm (range 1.3–6.7). 8 However, for reconstructions not including the condyle using a CAD/CAM guide, the postoperative deviations from the virtual plan were 2.4 mm 9 and 2.7 mm. 10 Thus, it seems that the deviations between postoperative data and the virtual plan in the reconstruction of the mandible including its condyle are larger than those for reconstructions not including the condyle.…”

Summary: In reconstructions of mandibles and condyles, free fibular flaps and metallic condylar heads (CH) are often used after resection. However, in conventional reconstructions, it is difficult to fix the metallic CH on the same preoperative position because the position is determined visually. Therefore, we have made an original computer-aided design and manufacture (CAD/CAM) guide for mandibular condyle reconstruction, combining a metallic CH with a free fibular flap. A 71-year-old woman with gingival carcinoma underwent hemimandibulectomy. We reconstructed the mandible and condyle with a metallic CH and a free fibular flap. We placed a mark on the CAD/CAM guide showing the correct position for fixing the CH to the fibular blocks. We also designed a surface for attaching to the healthy edge of the mandible. The fibular blocks and metallic CH were fixed as 1 unit before separating the flap from the leg and replacing the diseased tissue. Reconstruction was completed by fixing the attachment surface to the healthy side of the mandible. The guide marks solved the difficulty of conventional reconstruction; during surgery, we fixed the metallic CH to the same position as the original bone using these marks. The postoperative deviation of the condyle from the virtual plan was 4.3 mm, whereas the reported deviation of such prostheses was 3.8 mm (range 1.3–6.7); so our guide was acceptably accurate. Furthermore, it appears that the CAD/CAM guide is more useful for reconstruction after hemimandibulectomy including the condyle than after segmental resection without including condyle.

“…Em cirurgias ablativas, as placas de reconstrução com côndilo metálico adaptado são preferíveis como substitutos temporários, mas em alguns casos, podem ficar estabilizados por longos prazos, desde que o disco articular seja preservado, ou que seja feito o rebatimento de um pedículo miofascial para dentro da fossa mandibular (CARLSON et al, em 2002;DRIEMEL et al, 2005DRIEMEL et al, , 2007DRIEMEL et al, , 2009MARX et al, 2008;TARSITANO et al, 2017) Pela inexistência de estudos comparativos de longo prazo que pesquisem os benefícios estéticos e funcionais de cada dispositivo, fica impossível favorecer apenas um modelo de reconstrução da cabeça da mandíbula, sendo a escolha baseada na experiência, condições operatórias e preferência de cada cirurgião.…”

“…To address issues regarding bone segment movement and condylar shape, CAD/CAM technology has been utilized to make customized FFF and condylar prostheses as well as to reconstruct the mandible [14, 21]. VSP and CAD/CAM technology help produce a reconstruction plate including the condyle that matches the shape and position of the resected anatomical structure.…”

Background Condylar dislocation can arise as a complication in patients who required mandibular and/or condylar reconstruction and were operated on with fibula free flap (FFF) using surgical guides designed using simulation surgery. Surgeons should be aware of the complications in these present cases when planning and performing reconstructions as well as predicting prognoses. Cases presentation Two cases showed condylar dislocation in mandibular reconstruction using a FFF fixed with a reconstruction plate. Three cases showed condylar dislocation in mandibular reconstruction using a fibula free flap fixed with a mini-plate. Conclusion Despite the lack of clinical symptoms in these cases following mandibular reconstruction using an FFF, the mandibular condyle was severely displaced away from the glenoid fossa. A surgeon must have sufficient time to consider the use of a long flap with thickness similar to that of the mandible, ways to minimize span and bending, and methods of fixation. The patient, moreover, should be educated on condylar dislocation. Customized CAD/CAM-prototyped temporomandibular condyle-connected plates may be a good alternative even if virtual simulation surgery is to be performed before surgery. These considerations may help reduce the incidence of complications after mandibular reconstruction.
