“…Various surgical concepts to reconstruct maxillary defects have been presented in international literature including soft tissue or bone flaps alone or in combination with bone grafts and/or alloplastic materials (26)(27)(28)(29)(30). With each method having its advantages, soft tissue transplants alone generally neither allow bony reconstruction of the alveolar ridge necessary for the placement of dental implants nor do they provide sufficiently stable reshaping of the oral cavity for the use of removable dental prostheses, especially in the upper jaw.…”

Background: Maxillofacial osteosarcoma (MOS) is a rare disease, mostly located to the mandible or maxilla. Surgical resection with wide free margins represents the key intervention to achieve favorable prognosis. MOS are particularly demanding to resect and surgically reconstruct because of the numerous tissue types and functions included in this location. Case reports: We introduce two patients with a highly malignant maxillary OS treated by primary tumor resection and immediate reconstruction with a microvascular soft tissue flap. After confirmation of relapse-free tissue healing and sufficiently free resection margins, osseous reconstruction was performed in a second operation by use of a virtually planned microvascular Fibula Flap. Both patients received implant-supported dental rehabilitation and show relapse-free for seven and three years, respectively. Conclusions: Combination of radical tumor resection, primary soft tissue reconstruction and secondary bone reconstruction allows high oncologic safety and optimal conditions for a thoroughly planned osseous as well as dental rehabilitation.

“…PSI involves using computer-aided design (CAD) and computer-aided manufacturing (CAM) techniques to create customized implants based on the patient's preoperative imaging data [14]. The implants can be made of various biocompatible materials, such as titanium, polymethyl methacrylate (PMMA) [15], polyether ether ketone (PEEK) [16], or ceramic [17]. PSI offers several advantages over standard implants, such as improved accuracy, reduced intraoperative time, better cosmetic outcomes, and lower risk of infection or complications.…”

The repair and reconstruction of defects in the craniomaxillofacial region can be particularly challenging due to the complex anatomy, individuality of each defect, and sensitivity of the involved systems. This study aims to enhance the facial appearance and contribute to the reconstruction of the zygomatic arch. This was achieved through virtual planning of the surgery and assessment of clinical matching, including orbital measurements and registration of numerical models. A three-dimensional design of a young female case was generated on a skull model using Mimics® software, and the orbit was isolated using 3-Matic® to assess the reconstructive effect. 3D-printed implants were then surgically placed on the injured region, and Netfabb® software was used to make a virtual registration between the numerical models before and after the intervention. This allowed for the calculation of a deviation of 7 mm, equivalent to 86.23% of the shape restoration rate, to assess the success of the surgery. The computerized method enabled a precise design of the needed plates and analysis of the fixation places, resulting in a satisfactory cosmetic and functional outcome for the patient with minimal complications and good implant stability. Notably, a significant difference was observed in the orbital frontal area after 3 months of surgery (p < 0.001). Within the limitations of the study, these results suggest that virtual planning and customized titanium implants can serve as useful tools in the management of complex zygomatic-orbital injuries.

3D Printing in Eye Care

Three-dimensional printing enables precise modeling of anatomical structures and has been employed in a broad range of applications across medicine. Its earliest use in eye care included orbital models for training and surgical planning, which have subsequently enabled the design of custom-fit prostheses in oculoplastic surgery. It has evolved to include the production of surgical instruments, diagnostic tools, spectacles, and devices for delivery of drug and radiation therapy. During the COVID-19 pandemic, increased demand for personal protective equipment and supply chain shortages inspired many institutions to 3D-print their own eye protection. Cataract surgery, the most common procedure performed worldwide, may someday make use of custom-printed intraocular lenses. Perhaps its most alluring potential resides in the possibility of printing tissues at a cellular level to address unmet needs in the world of corneal and retinal diseases. Early models toward this end have shown promise for engineering tissues which, while not quite ready for transplantation, can serve as a useful model for in vitro disease and therapeutic research. As more institutions incorporate in-house or outsourced 3D printing for research models and clinical care, ethical and regulatory concerns will become a greater consideration. This report highlights the uses of 3D printing in eye care by subspecialty and clinical modality, with an aim to provide a useful entry point for anyone seeking to engage with the technology in their area of interest.
