Stereotaxis

Stereotaxis is a method used in neurosurgery and radiology to locate points within the body using a three-dimensional coordinate system. It is often used to guide the insertion of catheters, electrodes, or other surgical instruments and is particularly useful in minimally invasive procedures.

History[edit | edit source]

The concept of stereotaxis was first introduced by Victor Horsley and Robert H. Clarke in 1908. They developed the first stereotactic apparatus, which was used on animals. The first human stereotactic surgery was performed by Spiegel and Wycis in 1947.

Procedure[edit | edit source]

In a stereotactic procedure, the patient's head is fixed in a stereotactic frame, which serves as a reference point for the MRI or CT scan. The images obtained from these scans are used to calculate the coordinates of the target area. The surgeon then uses these coordinates to guide the surgical instrument to the target area with high precision.

Applications[edit | edit source]

Stereotaxis is used in various medical procedures, including biopsy, radiosurgery, and deep brain stimulation. It is also used in the treatment of Parkinson's disease, epilepsy, and brain tumors.

Advantages and Disadvantages[edit | edit source]

The main advantage of stereotaxis is its precision. It allows surgeons to reach target areas within the brain with minimal damage to surrounding tissues. However, it also has some disadvantages. For example, it requires the patient's head to be fixed in a frame, which can be uncomfortable. It also requires a high level of expertise and experience from the surgeon.
