Surgical planning

Using a surgical planning is an access path defined in the context of computer-assisted surgery prior to surgery or defines the displacement of a bone segment. The surgical planning has a high value in neurosurgery and maxillo -facial surgery. Reacting the surgical plan to the patient is then, in general, using a surgical navigation system.

Planning Fundamentals

Usually form the basis for surgical planning CT or MRI image data sets. In the mouth, jaw and facial surgery notwithstanding this operation plans in the context of orthognathic surgery can also be performed on the basis of plaster models of jaws in an articulator.

Historical development

For the operation of a three-dimensional planning image of the patient is required within which the planning is carried out. Pioneering in this context was the three-dimensional imaging in the context of computerized tomography by G. Hounsfield in the 70s. In the 80s, the radiologist M. Vannier and his team made ​​the first ever three-dimensional reconstruction of CT data on a computer. Early 90s could be made to stereolithography models then surgery planning for the first time. End of the 90s were first simulated in the framework of osteotomies and the computer and reacted with a navigation system on the patient surgery planning.
