[Mandibular reconstruction with fibula free flap. Experience of virtual reconstruction using Osirix®, a free and open source software for medical imagery].
The techniques of free tissue transfers are mainly used for mandibular reconstruction by specialized surgical teams. This type of reconstruction is mostly realized in matters of head and neck cancers affecting mandibular bone and requiring a wide surgical resection and interruption of the mandible. To decrease the duration of the operation, surgical procedure involves generally two teams, one devoted to cancer resection and the other one to raise the fibular flap and making the reconstruction. For a better preparation of this surgical procedure, we propose here the use of a medical imaging software enabling mandibular reconstructions in three dimensions using the CT-scan done during the initial disease-staging checkup. The software used is Osirix®, developed since 2004 by a team of radiologists from Geneva and UCLA, working on Apple® computers and downloadable free of charge in its basic version. We report here our experience of this software in 17 patients, with a preoperative modelling in three dimensions of the mandible, of the segment of mandible to be removed. It also forecasts the numbers of fragments of fibula needed and the location of osteotomies.
