Stereotactic Surgery

Stereotactic surgery is a surgical technique that uses three-dimensional coordinates to pinpoint anatomical structures inside the body, usually the brain. Stereotactic surgery allows for the minimally invasive application of energy fields to the brain and other structures inside the skull. This ability to precisely target one specific part of the brain minimizes the chances of inadvertently damaging nearby parts of the brain during the surgery. The stereotactic technique is used to insert electrodes, to remove tissue samples for examination, and to destroy small amounts of abnormal tissue.

1.Stereotactic Craniotomy
A craniotomy is the surgical removal of part of the bone from the skull to expose the brain. Specialized tools are used to remove the section of bone called bone flap. The bone flap is temporarily removed, then replaced after the brain surgery has been performed.

Some craniotomy procedures may utilize the guidance of computers and imaging (called intraoperative monitoring) to reach the precise location within the brain that is to be treated. This technique requires the use of a frame placed onto the skull or a frameless system using superficially placed markers on the scalp. When either of these imaging procedures is used along with the craniotomy procedure, it is called stereotactic craniotomy.

2.Stereotactic biopsy of the brain is done when a needle is guided into an abnormal area so that a piece of tissue may be removed for examination under a microscope. A stereotactic biopsy involves making a hole in the skull in order to take one or more small pieces of tumor for evaluation under the microscope (pathology). This procedure is done using advanced surgical navigation systems (stereotaxy), and sometimes involves the application of a stereotactic frame.

3.Stereotactic aspiration involves removal of fluid from abscesses, hematomas, or cysts.
Stereotactic Surgery is also used to treat disorders including chronic-pain syndromes, movement disorders and epilepsy.

4.Functional Neurosurgery
Stereotactic and Functional Neurosurgery offers minimally invasive and highly effective treatment options for many difficult neurological disorders and diseases. Stereotactic and Functional neurosurgery (SFNS) is that subspecialty of neurosurgery which is concerned with stereotactic and physiological techniques, including framed and frameless stereotactic systems, stereotactic radiosurgery, electrical recording, and electrical stimulation for localization and treatment of target structures in the central and peripheral nervous system (Stereotactic neurosurgery) and the surgical alteration of the nervous system (either by ablation or augmentation) to treat neurological diseases such as movement disorders, epilepsy, chronic pain, degenerative diseases, neurological injuries, and psychiatric disorders (Functional neurosurgery).
