Stereotactic Surgery
Stereotactic surgery is a surgery in which a system of three-
dimensional coordinates is used to locate the site to be operated on. Stereotactic surgery is used in neurosurgery (and neurological research) for locating points within the brain. This is usually done by
using an external, three-dimensional frame of reference based on the Cartesian
coordinate system.
Biopsy & Excisions of Brain Tumour
A biopsy
is usually required to definitely diagnose a brain tumor. The physician needs
to know the tumor type and grade to plan the proper treatment. A biopsy
involves removing a piece of the tumor for viewing under a microscope. A biopsy can be performed as part of surgery
to remove a brain tumor, or separately. A stereotactic biopsy can be used for
brain tumors in hard-to-reach areas. The surgeon drills a small hole into the
skull, and, guided by the computer, inserts a thin needle to obtain the tissue.
Biopsy is generally performed only for patients with tumors in critical
functional portions of the brain, where surgical removal (resection) would
result in unacceptable neurologic injury.
Minimally Invasive Surgery for Functional Disorders
Functional disorders cover a wide range of problems and many are not diseases as such but rather symptoms of certain underlying disorders.
Functional disorders stretch from the common Headache over the more violent Horstons headache and Migraine to diseases such as Epilepsy, Aphasia, Myasthenia Gravis to the more complex diseases such Neuralgia, Involuntary muscle movements, also called Dystonia, and further to dimmer disorders such as Tics in the form of Tourette's syndrome, Sleep Apnoea and Restless Legs Syndrome.
Minimally Invasive Surgery for Functional Disorders is performed by using CRW frame.
Surgery for Parkinsonism
Parkinsons
disease characterized by progressive increasing stiffness all over body, tremor in
limbs with difficulty in walking is no more incurable. These patients can be
benefited by stereotactic Neurosurgery. Parkinsons disease usually starts at
old age and slowly progresses over a period of time. Tremor and
stiffness increases, voice becomes slow, walking becomes more and more
difficult and ultimately patient has to lead a totally disabled and bedridden
life. Parkinsons disease is caused by imbalance of chemical Dopamine in the
brain, which causes overactivity of deep-seated nuclei of brain.
Its surgically treated
by implanting a pace maker in Brain known as DBS (Deep Brain Stimulation).
Recently we are using stem cell therapy for it.
Recently we are also in process of implanting Stem Cells into Substantia Nigra of the brain.
