Congenital orbital deformity correction surgery is still one of the most challenging operations for pediatric ophthalmologists. The main reasons are the fine movement of the eyeball and the complex musculoskeletal structure of the orbit. Many diseases, such as congenital orbital deformity, orbital facial trauma fracture, orbital tumor, etc., require ophthalmologists to repair the affected areas such as the eye socket and remove the lesion accurately, otherwise, blind operation brings great surgical trauma and risk. It is encouraging that today3DWith the introduction of printing technology, doctors were able to use3DPrint models to improve the accuracy of orbital implant surgery, achieve the best prognosis, and achieve true "precision medicine".
After a child named pengpeng was born, his right eye was difficult to open and his eyelids were sunken. After opening his eyes about a month, the parents were surprised to find that the child's eye socket was only a small eyeball the size of a bean, so they immediately took him to the outpatient clinic of our hospital. Recall the scene at that time: the child's right eye is basically invisible, and there is a soybean-sized "miniature eyeball without any function" in the sunken eye socket ". Head+OrbitMRIDisplay: The structure of the right eyeball is poorly displayed, the entire orbit is very poorly developed, and visual examination revealed that this eye has completely lost its vision. This is a case of a child with congenital microphthalmia. The purpose of treatment is to maximize the recovery of the child's appearance, but it must be started as soon as possible, otherwise very obvious orbital deformities and facial deformities will remain. After communicating in detail with parents and introducing the latest progress in the treatment of congenital microeyeball at home and abroad, I carefully formulated a set of systematic plastic surgery plan for my children: first of all, from2-3Starting to expand the anterior eye socket with artificial eye film in the next month;2At the age of 18, the implant expansion of the posterior segment of the orbit was started to stimulate the development of the posterior part of the orbit;4After the age of, eyelid enlargement and orthopedic surgery were performed.
10Month19Day, full.2The 18-year-old children came to review regularly. through near.2We found that the child's anterior orbital size and shape developed as scheduled, reaching the conditions for the second step of surgical implant. However, in order to preserve the child's own small eyes and protect the blood vessels and tissues in the orbit as much as possible, the appropriate implant size needs to be clarified, and the implantation location is also very critical. I began to consult the latest large amount of information at home and abroad, and came up with a bold idea: whether it is possible to pass the patient'sCTscan and MRI image data, through professional3Dmodeling software to reconstruct the position of the patient's orbital floor (I. e., the bottom of the eye socket) and eyeball, and3Dmodel is printed out, according1:1Scale size simulation3DOrbit, find the best approach for the implant and the most accurate implant shape and size. We will this idea and the most professional in our province.3DThe printing company-Hunan Jiayi 3D Technology Application Co., Ltd. contacted and reached a positive answer. The company's technicians came specially to take the child's eyes.CTSuch as professional data, made overnight3Drenderings, and will3DThe model was brought into the operating room. on the operating table, we refer3DThe simulation found the best approach to the lateral orbit and successfully implanted it.1×1cm2The size of the exfoliated cell dermis wrapped in the eye seat, and intact retain the child's original eyeball, the placement of the eye mask just corrected the orbital depression, but also to avoid the removal of the child's eyes, to achieve a satisfactory effect as scheduled. After the operation, we found3DThe information provided by the model about the orbital shape and the appendage structure of the eyeball is almost identical to that seen during the operation. Surprisingly, the muscle tissue is also imaged very well, giving very accurate guidance and tips for the operation!
21The century is witnessing.3DWith the rapid development of printing technology, this emerging technology has many famous applications in the construction, manufacturing and engineering fields. Recently, it has also begun to be applied in the medical field, most of which are found in orthopedics and stomatology. This time is3DPrinting is first used in the correction of congenital orbital deformities, but it brings very exciting information. In the future, this technology will be used to design surgical plans to make surgery more accurate and intuitive. We're going to continue to track this child's orbital development later, and6Passthrough in a month.3Dtechnology to simulate orbital shaping, and preoperative3Dmodel comparison to understand the child's orbital enlargement; it will also explore3DThe application of technology in eye muscle simulation is expected to bring new hope to children with strabismus and more children with eye deformities!
