Abstract
Background: Vascularized bone flaps are now considered the benchmark for reconstructing the mandible. In recent years, virtual surgical planning has transformed the process of bone reconstruction. The procedure nowadays has far better outcomes in both functional and aesthetic aspects. Moreover, the operating times has significantly decreased with the continuous development of new advances. In addition, learning curve for surgeons has become less steep. Aim and Objectives: To compare mandibular reconstruction by free vascularized fibula using 3D models and Patient specific plate (pre bent by a manufacturer) with conventional free hand reconstruction method in our practice. Patients and Methods: This aim was achieved by comparing two groups of patients operated by the same surgeon. In group A virtual planning was used. On the other hand, a conventional free hand technique was used in group B. The 2 groups were compared regarding the operative time and the accuracy of reconstruction using radiological landmarks and measurements. Results: Our results showed a statistically significant reduction in operative time in Group A when compared to group < br />B. Moreover, there was a non-statistically significant improvement regarding accuracy of the reconstruction in group A. Conclusion: The Use of Virtual Surgical Planning & Patient Specific Plate (pre bent) for mandibular reconstruction can reduce the operative time and improve the accuracy of reconstruction.
