Abstract
Oro-maxillo-facial surgery in oncological patients is particularly challenging due to the complex nature of the disease and its treatment, which often involves extensive tissue resection and reconstruction. Traditional surgical techniques can result in functional and aesthetic deficits, and the risk of complications is high. The use of 3D printing (3DP) technology has revolutionized the field of Oro-maxillo-facial surgery, particularly in the area of mandibular reconstruction with vascularized peroneal graft and musculocutaneous flap. This complex procedure requires a multidisciplinary team, including an OMF surgeon, plastic surgery doctor, oncologist, medical imaging doctor, and technical team composed of graphics software expert and 3DP technician. 3DP is a revolutionary manufacturing technology, with immense potential impact on the medical field. In order to implement this technology into current medical practice requires the development of a workflow that enables efficient communication between members of the multidisciplinary team and the creation of accurate, patient-specific models that can be used for pre-surgical planning and for designing 3DP surgical guides. The design protocol of these surgical guides involves several steps, form correct image acquisition, DICOM segmentation of the region of interest, digital design of the surgical guide based on the patient's anatomy, selecting the appropriate 3DP technology and material, and validating the design. Combined, the use of 3DP technology and digital 3D workflows has greatly improved the accuracy and precision of mandibular reconstruction procedures, resulting in safer and shorter surgical procedures, with better outcomes for the patients.
