“…Craniofacial surgeons currently face the challenge of producing high-quality evidence to define: criteria that warrant the use of advanced 3D technologies, a viable balance between in-house production and outsourcing of resources to industry, a timeline for the production and delivery of 3DPCIs, standards for ethical interaction with commercial providers of 3D reconstructive services to plastic surgeons, the value of 3D reconstructive technologies in medical education, the optimal biomaterials for use in 3DPCIs, and long-term outcomes of this approach. 4 , 18 – 21 , 27 , 44 …”

Background:To demonstrate our use of advanced 3-dimensional (3D) computer technology in the analysis, virtual surgical planning (VSP), 3D modeling (3DM), and treatment of complex congenital and acquired craniofacial deformities.Methods:We present a series of craniofacial defects treated at a tertiary craniofacial referral center utilizing state-of-the-art 3D computer technology. All patients treated at our center using computer-assisted VSP, prefabricated custom-designed 3DMs, and/or 3D printed custom implants (3DPCI) in the reconstruction of craniofacial defects were included in this analysis.Results:We describe the use of 3D computer technology to precisely analyze, plan, and reconstruct 31 craniofacial deformities/syndromes caused by: Pierre-Robin (7), Treacher Collins (5), Apert’s (2), Pfeiffer (2), Crouzon (1) Syndromes, craniosynostosis (6), hemifacial microsomia (2), micrognathia (2), multiple facial clefts (1), and trauma (3). In select cases where the available bone was insufficient for skeletal reconstruction, 3DPCIs were fabricated using 3D printing. We used VSP in 30, 3DMs in all 31, distraction osteogenesis in 16, and 3DPCIs in 13 cases. Utilizing these technologies, the above complex craniofacial defects were corrected without significant complications and with excellent aesthetic results.Conclusion:Modern 3D technology allows the surgeon to better analyze complex craniofacial deformities, precisely plan surgical correction with computer simulation of results, customize osteotomies, plan distractions, and print 3DPCI, as needed. The use of advanced 3D computer technology can be applied safely and potentially improve aesthetic and functional outcomes after complex craniofacial reconstruction. These techniques warrant further study and may be reproducible in various centers of care.

The principles for a successful rhinoplasty include preoperative consultation and planning, as well as a comprehensive clinical analysis and defining rhinoplasty goals. Three-dimensional domestic scanning and printing have recently become available. We sought to objectively describe this method as an intraoperative aid in patients' anatomy. This method can be used trans-operatively to help surgeons compare the results of his or her technique, check adherence to the surgical plan, and improve his or her surgical decision-making. We found that the application of 3-dimensional printing had a positive effect on the treatment of patients with aesthetic nose disorders.

“…Thereafter, its usefulness in various surgical methods, including reconstruction, have been reported 6,7) . However, reconstruction plate bending and simulations of grafted bone using a 3D model are not established methods 8) , so it is difficult to suitability the grafted bone into the mandible. Therefore, we improved these procedures using a special dental method.…”

When performing mandibular reconstruction following mandibular segmentectomy, the surgical method that we have been using involves creating a surgical guide plate using a three dimensions model for bending the mandible reconstruction plate. It has been reported that the current method results in an excellent suitability of the graft into the mandible, which allows for a highly esthetic recovery. The purpose of the present study was to evaluate how well the current surgical method enables the grafted bone to suitability within the mandibular defect in terms of esthetics and functionality by measuring masticatory performance using a gummy score method. We enrolled 11 patients who had undergone mandibular reconstruction using the current method following mandibular tumorectomy at Osaka Medical College Hospital. Among them, 6 evaluable patients were examined using the gummy score method and occlusal force measurement two months after the operation. Gummy score evaluations were performed while masticating on a whole and then a half-portion gummy jelly, taking into account the decline in occlusal force. The results revealed a declining tendency in masticatory performance and occlusal force; however, adequate masticatory performance was obtained with the half-portion gummy jelly. We believe that the gummy score method using a test gummy jelly is a useful tool in evaluating whether a functionally good suitability between the grafted bone and the mandible has been achieved after mandibular reconstruction using the current method.
