The surgical navigation represents a new way to operate, through the use of a particular tool : the navigator
The surgical navigator can track the anatomic features of the patient previously seen through x-rays exams, in particula the computed tomography and the M.R.I. Using these exams as a map and the surgical instruments as probes, the navigator allows to know where the instruments and the sane or pathologic areas are. Furthermore it can verify the accuracy of the surgical program elaborated by virtual planning software.
The real heart of the equipment is an infrared camera that allows communication among instruments that are a detector located on the patient's head and a cursor: this one lets the surgeon exactly define his special position at the facial level. On the screen the virtual project is seen (blue definition colour) : the cursor (as a line) can 3D define the position of the surgical instrument, then the surgeon can move the bones to obtain the precise location coinciding with blue colour (virtual project). The navigation has been studied for many years by our team, with a particular effectiveness in genetic malformations or acquired. Working on the 3D recostruction of the anatomy can check the complete accuracy of virtually planned surgical project.
