RESUMO
We present material to define and understand the concept of Stereolithography (STL) and its potential benefits to the field of neurosurgery and other medical specialties. A historical and scientific review of the literature on stereolithography, its evolution and uses in neurosurgery, forensic medicine, and other medical specialties are described. Considerations regarding different techniques used to obtain STL are discussed. The reproduction of cranial and vascular structures using this technique is evaluated. Data acquisition and model fabrication are the two basic steps required for stereolithography to create custom models for multiple applications in cranio-facial surgery, vascular studies, orthopedic surgery, urology and forensic medicine, among others. Stereolithography is a relatively new technique which continues to grow in many medical fields. Pre-operative education of patients, better understanding of patient anatomy, and the creation of custom-made prostheses are proven benefits of this technique.
