Forehead and facial surface anatomical landmarks were obtained with the laser pointer scanner. Stereotactic surgery or stereotaxy is a minimally invasive form of surgical intervention which makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablationbiopsylesioninjection, stimulationimplantation, radiosurgery SRSetc.

The application accuracy of stereotactic frames. The software used for neuronavigation was Cranial Navigation v. However, target motion requires larger treatment margins around the target to compensate for the positioning uncertainty.
