A Comparative Study of Analog Preoperative Planning Versus Virtual Preoperative Planning for Mandibular...

Mandibular reconstruction is a challenging procedure, especially in cancer patients with defects that are greater than 6 cm. Free vascularized fibular flap is the gold standard treatment in these cases since it allows three-dimensional restoration of the lost segments after ablative surgery in addition to providing the possibility of a subsequent implant-supported rehabilitation improving the functional and aesthetic outcomes of the surgery.To obtain accurate results, preoperative planning must be done with detail. Approaches for the preoperative planning include both the conventional analog planning and the virtual planning that are valid alternatives in meeting the trans-surgical requirements.This study makes a comparative analysis of 2 clinical cases with a diagnosis of squamous cell carcinoma that were reconstructed using a vascularized fibular free flap. The first case was planned using the conventional analog method whereas the second case was planned using the virtual planning approach.The impact of virtual planning and conventional analog planning on preoperative planning time, ischemia period, and total surgical time is analyzed according to the experience obtained in the cases presented. In addition, the authors described the technique used for each planning method along with a literature review in which the results are contrasted and discussed.
