Accelerated workflow for primary jaw reconstruction with microvascular fibula graft

چکیده
Introduction: Major facial defects due to cancer or deformities can be reconstructed through microvascular osteocutaneous flaps. Hereby CAD/CAM workflows offer a possibility to optimize reconstruct and reduce surgical time. We present a retrospectiv observational study regarding the developement of an in-house workflow allowing an accelerated CAD/CAM fibula reconstruction without outsourcing. Case description: Workflow includes data acquisition through computertomography of head and legs, segmentation of the data and virtual surgery. The virtual surgery was transferred into surgical guides and prebent osteosynthesis plate. Those were sterilized and used in surgery. Evaluation: The workflow was used in 30 cases. Minimum planning period took 4 days from CT to surgery, average time was 8 days. Planning could be transferred to surgery every time. Intraoperative complications regarding osteotomy, assembly and fixation did not occur. Discussion/Conclusion: An in-house workflow for CAD/CAM fibula reconstruction is feasible within a few days providing an accelerated procedure even in urgent cases.

Accuracy of secondary maxillofacial reconstruction with prefabricated fibula grafts using 3D planning and guided reconstruction.
BACKGROUND We compared the pre-operative 3D-surgical plan with the surgical outcome of complex two-stage secondary reconstruction of maxillofacial defects using inserted implants in the prefabricated fibula graft. METHODS Eleven reconstructions of maxillofacial defects with prefabricated fibulas were performed using a 3D virtual planning. Accuracy of placement of the fibula grafts and dental ...

Objective: This study was done to evaluate the changes in vascularised free fibula graft for mandible reconstruction with respect to height of fibula graft and bony union at the ends of graft and osteotomy sites. Methods: A follow up study was conduted with 5 cases of mandibular resection due to aggressive benign tumor and reconstruction with vascularised free fibula flap. Changes in bone heigh...
متن کاملReconstruction of the maxilla using a fibula graft and virtual planning techniques.
Use of a vascularised free fibula flap has been a popular method of osseous reconstruction because of its adequate length and acceptance of dental implants. In this article we describe a case of maxillary reconstruction in which virtual planning techniques and rapid prototyping were used to insert a microvascular osteomyocutaneous fibula graft, Medpor implant, and immediate dental implants.
متن کاملReconstruction of a maxillary defect with a fibula graft and titanium mesh using CAD/CAM techniques.
We present a case of maxillary and orbital floor reconstruction with a microvascular fibula graft and an individualized titanium mesh. Both were planned virtually; templates were made by rapid prototyping. The postoperative computer tomography scans showed that the planned positions were achieved correctly. This case report illustrates maxillary reconstruction performed with a special template ...

BACKGROUND Mandibular pseudocarcinomatous hyperplasia is a rare and generally benign pathology. We report on one of these rare cases. CASE PRESENTATION The case history of a 73-year-old white man stated that he had a carcinoma of the oropharynx, which was primarily treated with radiotherapy and chemotherapy 4 years prior. As a result of radiotherapy he developed an osteoradionecrosis of his m...
