Frameless Stereotactic Craniotomy

Craniotomy is the fundamental technique used in brain tumor resection. It involves making an incision in the patient's scalp and then creating an opening in the skull. This opening allows access to the intracranial space where the tumor is located. Tumor resection is often guided by computer aided stereotactic techniques. These techniques make use of a computer system that incorporates information from diagnostic tests such as MRI and CT scans to aid in intracranial navigation.

Use of stereotaxy allows precise placement of the scalp incision and bone opening to provide optimal access to a tumor. This precision permits the use of minimally invasive surgical techniques, and as surgical openings have become smaller, associated morbidity has declined in brain tumor procedures. Another advantage to stereotaxis is that it provides the ability to navigate within brain and tumor tissue. The use of stereotactic equipment and methods allows the safe removal of deep-seated tumors, which were often considered inoperable in the past.
