ABSTRACT
Free vascularised fibular flap has many advantages in repair of mandibular defects, and it has become the main method in the mandibular reconstruction. However, the traditional free fibular flap used to repair the mandibular defect is lack of individualised design and precise surgical guidance, and it is difficult to achieve accurate repair and the effect of reconstruction. The concept of personalised and accurate functional reconstruction and the clinically application of digital medical technology provides a new approach to solve the problems. The application of digital medical technology in the repair of mandibular defects with fibular flap is one of the hotspots of current research. This article introduces the application characteristics of digital medical technology, such as 3-dimensional reconstruction technology, virtual surgery planning (VSP) technology and 3D printing technology, in the repair of mandibular defects with fibular flap transfer.
