“…Multiple domains use anatomical models for surgical planning. Our research showed anatomical models being used in cardiovascular surgery, vascular neurosurgery, dental surgery, general surgery, maxillofacial surgery, neurosurgery, cranial/orbital surgery, orthopedics, and spinal surgery [ 1 – 3 , 9 , 14 , 15 , 35 , 37 , 39 , 43 – 121 ]. Among the 89 studies, 48 (53.93 %) mentioned reduced operation room time.…”

BackgroundThree-dimensional (3D) printing has numerous applications and has gained much interest in the medical world. The constantly improving quality of 3D-printing applications has contributed to their increased use on patients. This paper summarizes the literature on surgical 3D-printing applications used on patients, with a focus on reported clinical and economic outcomes.MethodsThree major literature databases were screened for case series (more than three cases described in the same study) and trials of surgical applications of 3D printing in humans.Results227 surgical papers were analyzed and summarized using an evidence table. The papers described the use of 3D printing for surgical guides, anatomical models, and custom implants. 3D printing is used in multiple surgical domains, such as orthopedics, maxillofacial surgery, cranial surgery, and spinal surgery. In general, the advantages of 3D-printed parts are said to include reduced surgical time, improved medical outcome, and decreased radiation exposure. The costs of printing and additional scans generally increase the overall cost of the procedure.Conclusion3D printing is well integrated in surgical practice and research. Applications vary from anatomical models mainly intended for surgical planning to surgical guides and implants. Our research suggests that there are several advantages to 3D-printed applications, but that further research is needed to determine whether the increased intervention costs can be balanced with the observable advantages of this new technology. There is a need for a formal cost–effectiveness analysis.Electronic supplementary materialThe online version of this article (doi:10.1186/s12938-016-0236-4) contains supplementary material, which is available to authorized users.

“…This concept has been extensively applied in Oral Maxillofac Surg For example, published applications include printing anatomical models of a variety of cranial and facial bones to shape titanium implants (86)(87)(88), printing a skull and orbital model for the molding of synthetic scaffolds in the correction of post-traumatic orbital deformity (89), printing a mandibular defect to design a surgical guide (90,91), and using a model of the pelvis to design a surgical guide for pelvic graft harvest (92). Beyond simply using the anatomic model to physically shape the implant, these models have also been used to engineer implant structure and analyze the stress distribution transferred to the implant (93).…”

Three dimensional (3D) printing involves a number of additive manufacturing techniques that are used to build structures from the ground up. This technology has been adapted to a wide range of surgical applications at an impressive rate. It has been used to print patient-specific anatomic models, implants, prosthetics, external fixators, splints, surgical instrumentation, and surgical cutting guides. The profound utility of this technology in surgery explains the exponential growth. It is important to learn how 3D printing has been used in surgery and how to potentially apply this technology. PubMed was searched for studies that addressed the clinical application of 3D printing in all surgical fields, yielding 442 results. Data was manually extracted from the 168 included studies. We found an exponential increase in studies addressing surgical applications for 3D printing since 2011, with the largest growth in craniofacial, oromaxillofacial, and cardiothoracic specialties. The pertinent considerations for getting started with 3D printing were identified and are discussed, including, software, printing techniques, printing materials, sterilization of printing materials, and cost and time requirements. Also, the diverse and increasing applications of 3D printing were recorded and are discussed. There is large array of potential applications for 3D printing. Decreasing cost and increasing ease of use are making this technology more available. Incorporating 3D printing into a surgical practice can be a rewarding process that yields impressive results.

“…Orbital fractures account for approximately 40% of craniofacial traumas. A large portion of orbital cavity fractures often occurs in the orbital inferior wall, in the infraorbital groove and canal, and in the medial orbital wall [ 1 2 3 4 ]. These bony fractures can alter cavity dimensions and shift the position of intraorbital contents, resulting in diplopia, enophthalmos, and visual acuity disturbances [ 4 ].…”

BackgroundRestoring the orbital cavity in large blow out fractures is a challenge for surgeons due to the anatomical complexity. This study evaluated the clinical outcomes and orbital volume after orbital wall fracture repair using a rapid prototyping (RP) technique and intraoperative navigation system.MethodsThis prospective study was conducted on the medical records and radiology records of 12 patients who had undergone a unilateral blow out fracture reconstruction using a RP technique and an intraoperative navigation system from November 2014 to March 2015. The surgical results were assessed by an ophthalmic examination and a comparison of the preoperative and postoperative orbital volume ratio (OVR) values.ResultsAll patients had a successful treatment outcome without complications. Volumetric analysis revealed a significant decrease in the mean OVR from 1.0952±0.0662 (ranging from 0.9917 to 1.2509) preoperatively to 0.9942±0.0427 (ranging from 0.9394 to 1.0680) postoperatively.ConclusionThe application of a RP technique for the repair of orbital wall fractures is a useful tool that may help improve the clinical outcomes by understanding the individual anatomy, determining the operability, and restoring the orbital cavity volume through optimal implant positioning along with an intraoperative navigation system.
