Deep Brain Stimulation (DBS) Surgery in Hyderabad
Restore movement, reduce tremor, and reclaim daily independence. Dr. Sayuj Krishnan offers advanced DBS surgery with ROSA robotic guidance at Yashoda Hospital, Malakpet -- delivering sub-millimetre electrode accuracy for patients with Parkinson's disease, essential tremor, dystonia, and OCD.
What is Deep Brain Stimulation?
Deep Brain Stimulation is a neurosurgical procedure in which thin, insulated electrodes are precisely implanted into specific targets deep within the brain. These electrodes are connected via subcutaneous wires to a small, programmable pulse generator -- often called a "brain pacemaker" -- placed beneath the collarbone. The device delivers continuous, low-voltage electrical impulses that modulate the abnormal neural circuits responsible for movement disorders and certain psychiatric conditions.
Unlike ablative procedures that permanently destroy brain tissue, DBS is reversible and adjustable. Stimulation parameters -- including voltage, frequency, and pulse width -- can be fine-tuned non-invasively during follow-up visits to optimise symptom control while minimising side effects. If needed, the system can be turned off entirely without lasting effects on brain function.
First approved by the FDA in 1997 for essential tremor and in 2002 for Parkinson's disease, DBS has since been used in over 200,000 patients worldwide. It represents one of the most significant advances in the management of medication-resistant neurological disorders over the past three decades.
Conditions Treated with DBS
DBS is a proven surgical treatment for neurological and psychiatric conditions that no longer respond adequately to medication alone.
Parkinson's Disease
Target: Sub-thalamic nucleus (STN) or Globus pallidus interna (GPi)
Expected benefit: 50-70% reduction in OFF-state motor symptoms (tremor, rigidity, bradykinesia); 60-80% reduction in medication-induced dyskinesias; significant levodopa dose reduction in most patients.
Who qualifies: Stage 3-4 Parkinson's with motor fluctuations or dyskinesias despite optimised medication, with preserved cognition
Essential Tremor
Target: Ventral intermediate nucleus (VIM) of the thalamus
Expected benefit: 80-90% tremor suppression in the targeted hand; restoration of ability to write, eat, drink, and perform fine motor tasks independently.
Who qualifies: Disabling tremor unresponsive to propranolol and primidone; significant functional impairment in daily activities
Dystonia
Target: Globus pallidus interna (GPi)
Expected benefit: Significant and sustained reduction in abnormal postures and involuntary movements; benefits may continue improving for 6-12 months post-implantation.
Who qualifies: Primary generalised or segmental dystonia; DYT1 mutation carriers; cervical dystonia unresponsive to botulinum toxin
Obsessive-Compulsive Disorder (OCD)
Target: Ventral capsule / ventral striatum (VC/VS) or anterior limb of internal capsule
Expected benefit: Approximately 60% of carefully selected patients achieve clinically significant symptom reduction (35% or greater improvement on Y-BOCS scale).
Who qualifies: Severe, treatment-resistant OCD unresponsive to adequate trials of medication and cognitive behavioural therapy
Living with uncontrolled tremor, rigidity, or involuntary movements?
A dedicated evaluation can determine whether DBS is the right treatment for your condition. Dr. Sayuj Krishnan offers comprehensive consultations at Yashoda Hospital, Malakpet.
Book a DBS EvaluationThe ROSA Robot Advantage
At Yashoda Hospital, Dr. Sayuj Krishnan performs DBS using the ROSA (Robotic Surgical Assistant)system -- an FDA-cleared surgical robot designed specifically for stereotactic neurosurgery. ROSA replaces the traditional rigid head frame with a robotic arm that registers directly to the patient's pre-operative MRI and CT scans, guiding electrode trajectories with sub-millimetre precision.
ROSA Robotic DBS vs. Conventional Frame-Based DBS
| Feature | ROSA Robotic DBS | Frame-Based DBS |
|---|---|---|
| Electrode accuracy | 0.5-0.7 mm | 1.0-1.5 mm |
| Head fixation | Frameless (no skull pins) | Rigid metal frame bolted to skull |
| Patient comfort | Significantly higher | Frame causes discomfort throughout |
| Operative time | Approximately 30% shorter | Standard duration |
| Brain passes required | Fewer (better first-pass accuracy) | More passes sometimes needed |
| Intra-operative flexibility | Real-time trajectory adjustment | Limited by fixed frame geometry |
ROSA robotic guidance is integrated into Dr. Sayuj Krishnan's DBS pathway at Yashoda Hospital, combining frameless planning, precise electrode targeting, and structured post-operative programming support.
DBS Surgery Procedure: Step by Step
Comprehensive Pre-Surgical Evaluation
A multidisciplinary team -- including a movement disorder neurologist, neurosurgeon, neuropsychologist, and psychiatrist -- performs a thorough assessment over 2-4 weeks. This includes neurological examination, neuropsychological testing to evaluate cognition and mood, high-resolution brain MRI, and a levodopa challenge test for Parkinson's patients. Only patients meeting strict medical criteria proceed to surgery.
Surgical Planning with ROSA
Pre-operative MRI and CT scans are fused using ROSA's planning software. The neurosurgeon maps the optimal electrode trajectory to the target nucleus -- avoiding blood vessels, ventricles, and eloquent brain structures. The ROSA robotic arm is registered to this personalised surgical plan on the morning of surgery.
Awake Electrode Implantation (3-4 hours)
Under local anaesthesia, a small burr-hole is made in the skull. The ROSA robot guides the microelectrode recording (MER) probe to the planned target. Real-time neurophysiological recording confirms the target nucleus. The permanent DBS electrode is then implanted, and the patient is tested for motor improvement and side effects while awake. For bilateral implantation, the process is repeated on the second side.
Pulse Generator (IPG) Implantation (1-1.5 hours)
Under general anaesthesia -- either the same day or in a staged second procedure -- the pulse generator is placed in a small pocket below the collarbone. A subcutaneous extension cable connects the generator to the brain electrodes. The incision is closed and the device is tested before the patient wakes.
Post-Operative Recovery (3-5 days)
Patients remain in hospital for monitoring. A post-operative CT scan confirms electrode position. Pain is managed with standard medications. Most patients can walk and eat normally within 24-48 hours. Sutures are removed at 10-14 days.
Programming and Optimisation (2-4 weeks onward)
Initial stimulation programming begins 2-4 weeks after surgery once brain swelling resolves. The neurologist and neurosurgeon adjust voltage, frequency, and pulse width across multiple sessions over 3-6 months to achieve the best balance of symptom control and minimal side effects. Medication doses are gradually reduced as stimulation takes effect.
Who is a Good Candidate for DBS?
DBS is not appropriate for every patient with a movement disorder. Careful patient selection is one of the most important factors determining surgical success. The following criteria guide our evaluation:
Likely Candidates
- +Parkinson's patients with motor fluctuations or dyskinesias despite optimised levodopa therapy
- +Essential tremor causing significant disability unresponsive to medications
- +Primary generalised or segmental dystonia, especially DYT1 carriers
- +Severe OCD unresponsive to adequate medication and CBT trials
- +Good general health and ability to tolerate surgery
