Résumé
Ameloblastoma is a histologically benign tumor that behaves aggressively because of its tendency to invade local structures, and it has a high probability of local recurrence. If neglected, ameloblastomas can grow substantially over the course of years, reaching the size of giant ameloblastomas. This large size can lead to deformities in facial appearance and impairments in speaking, swallowing, eating, and breathing.Surgical planning can be challenging because of the extension of the tumor and the consequent reconstructive issues.In this article, we present our experience with the reconstruction of 2 cases of giant ameloblastomas planned on the basis of occlusal casts and acrylic splints. In these patients, computerized planning was rendered complex and potentially inaccurate because of the dimensions of the tumor, the loss of anatomical landmarks, and the loss of occlusal landmarks. The cases were successfully reconstructed, but the technique can be flawed. A 3-dimensional virtual model of the mandible can be used as a template to develop cutting guides for reconstruction with free fibular flaps. This will allow us to overcome limitations, standardize the procedure, and achieve optimal functional and aesthetic results.
