“…PSIs have a growing use in both spinal and cranial procedures. The literature review shows that most of the spinal uses include patient-specific cages, plates, and rods [16][17][18], while most of the cranial uses include customized patient-specific bone flap substitutes and bony craniofacial reconstructions [12,13]. An issue that is worth noting is the certification of the materials and machines for use in patients -this can be a significant barrier to the wider application of the technology.…”

IntroductionThree-dimensional (3D) printing is an affordable aid that is useful in neurosurgery. It allows for better visualization and tactile appreciation of the individual anatomy and regions of interest and therefore potentially lowers the risk of complications. There are various applications of this technology in the field of neurosurgery. Materials and methodsIn this paper, we present a basic methodology for the creation of a 3D printed model using only open-source software for medical image editing, model generation, pre-printing preparation, and analysis of the literature concerning the practical use of this methodology. ResultsThe literature review on the current applications of 3D printed models in neurosurgery shows that they are mostly used for preoperative planning, surgical training, and simulation, closely followed by their use in patient-specific implants and instrumentation and medical education. Materialise TM Mimics is the most frequently used commercial software for a 3D modeling for preoperative planning and surgical simulation, while the most popular open-source software for the same applications is 3D Slicer. In this paper, we present the algorithm that we employ for 3D printing using Horos TM , Blender, and Cura software packages which are all free and open-source. ConclusionThree-dimensional printing is becoming widely available and of significance to neurosurgical practice. Currently, there are various applications of this technology that are less demanding in terms of technical knowledge and required fluency in medical imaging software. These predispositions open the field for further research on the possible use of 3D printing in neurosurgery.

“…In the development and formation of congenital and acquired deformities of the jaws, according to the literature, the tone of the masticatory and facial muscles of the maxillofacial region, bad habits, birth trauma, changes in the function of the temporomandibular joint play a role [9]. Facial asymmetry has a negative effect on the appearance, facial expressions of patients and, as a result, on the psycho-emotional state [10]. In childhood, only a part of the skeletal anomalies of the jaws and occlusion disorders can be corrected by orthodontic treatment.…”

“…In the treatment and correction of occlusion, the anatomical and pathogenetic features of the facial skull are often not taken into account. Etiological factors, functional features, the ratio of the dentition, the state of the temporomandibular joint and the difficulties of diagnosis negatively affect the outcome and outcome of treatment [12]. This approach to treatment in the literature is called "camouflage", since, most often, it is not possible to correct the significant deformity underlying the occlusion anomaly and asymmetry of the jaws.…”

The high growth of injuries, the absence in the country of a unified approach to the treatment of victims with pathology of the bones of the face and skull leads to a sharp increase in the number of patients with post-traumatic deformities, defects, often to their disability and death. This problem has recently acquired the greatest importance in connection with the increase in the number of victims in areas of natural disasters and road traffic accidents. Severe multiple fractures of the bones of the middle zone of the facial skeleton, accompanied by craniocerebral trauma of varying degrees, bleeding and liquorrhea, are often outwardly unnoticeable, since they are hidden by pronounced edema, hemorrhages in soft tissues, and can only be determined with a targeted specialized examination. These types of examinations and the provision of specialized medical care are possible only in multidisciplinary centers. Therefore, these types of injuries are not always diagnosed in a timely manner, especially in severely injured with the presence of pronounced injuries of other localizations.

The purpose of this study is to execute an evidence-based review answering the following question (PICO): “Do patient-specific implants (PSI), manufactured or designed using computer-assisted technology, improve outcomes (orbital volume change, enophthalmos, diplopia, and operative duration) compared to conventional methods in orbital reconstruction following traumatic orbital injury in the adult patient population?” We performed a systematic review and meta-analysis in accordance with PRISMA guidelines. Inclusion criteria included any comparative paper whereby computer-assisted technology was used in the prefabrication or design process of implants for use in post-traumatic orbital reconstruction. Paediatric patient populations were excluded. Eight databases were systematically searched for relevant studies. Risk of bias was assessed through the NOS and RoB2 tools. Random-effects models were used to identify differences in outcomes between groups where possible. Analysis was performed using R 4.0.0. Eleven of 4784 identified studies were included, comprising 628 adult patients, with 302 and 326 patients in the patient-specific and conventional groups, respectively. Weighted mean difference between unaffected and post-operative orbital volume was 0.32 ml (SD 0.75) and 0.95 ml (SD 1.03) for patient-specific and conventional groups, respectively. Significant improvement was identified in post-operative orbital volume reconstitution with the use of PSI, compared to conventional implants, in 3 of the 5 reporting studies. Equally, post-operative enophthalmos trended towards lower severity in the patient-specific group, with 11.2% of patients affected in the patient-specific group and 19.2% in the conventional group, and operative duration was significantly reduced with the use of PSI in 3 of the 6 reporting studies. Despite a tendency to favour PSI, no statistically significant differences in key outcomes were identified on meta-analysis. Although there is some encouraging data to support improved outcomes with the use of patient-specific orbital implants in post-traumatic reconstruction, there is, at present, no statistically significant evidence to objectively support their use over conventional implants based on the currently available comparative studies. Based on the results of this study, the choice of implant used should, thus, be left to the discretion of the surgeon.
