The Problem
Clinical Condition
The patient presented with severe, bilateral essential tremor, a progressive neurological movement disorder causing uncontrollable rhythmic oscillations in both hands. The tremors were action-type and postural, most pronounced during purposeful movement such as reaching, gripping, or writing, with the right hand showing slightly greater impairment. Clinically graded as severe, the tremors exceeded the threshold where medication offers meaningful benefit, a pattern also seen in Parkinson’s disease once drugs stop controlling symptoms. At this point, Parkinson’s Surgery in Mumbai becomes the next option.
Functional & Psychological Impact
For a 78-year-old living independently, the impact of bilateral hand tremors is total. Activities most people perform without a second thought – holding a glass of water, eating without spilling, signing a document, fastening buttons – had become unreliable or impossible for this patient. The condition had progressively eroded his autonomy over several years, and prior medication had provided insufficient relief. Beyond the physical limitations, the psychological burden was significant: the constant visibility of the tremors in social settings created self-consciousness and withdrawal, and the growing dependence on others for basic tasks was a direct threat to his sense of independence. Patients with severe essential tremor frequently describe the condition as more disabling than its clinical description suggests, and this case was consistent with that pattern.
Consultation & Treatment Plan
Assessment Parameters
- Tremor characterisation: type (action/postural/resting), amplitude, and frequency bilaterally
- Functional disability grading across activities of daily living using standardised tremor scales
- Neuroimaging review to exclude secondary causes and confirm thalamic target suitability
- Medical fitness for procedure under local or monitored anaesthesia – age-appropriate pre-anaesthetic workup
- Patient goals: restoration of independence, particularly in eating, drinking, and fine motor tasks
- Patient preference and capacity to undergo a two-stage procedure with a defined interval between sides
Why Radiofrequency Ablation Was Chosen
Radiofrequency (RF) Lesioning, also referred to as RF Ablation or thalamotomy, involves creating a precisely targeted thermal lesion in the ventral intermediate nucleus (Vim) of the thalamus, which disrupts the aberrant tremor-generating circuit. This falls under the broader scope of functional neurosurgery, a subspecialty focused on surgical correction of neurological dysfunction. For this patient, the following clinical reasoning drove the decision:
- Severity beyond pharmacological threshold: medication had failed to provide adequate control, and the tremor amplitude was severe enough to warrant a definitive surgical intervention
- Age and risk profile: RF lesioning is a shorter, less implant-dependent procedure than deep brain stimulation (DBS), making it appropriate for older patients where device implant burden, battery management, and long-term programming follow-up are relevant considerations
- Staged bilateral approach: bilateral simultaneous thalamotomy carries dysarthria risk; a one-year interval between the right and left procedures allowed full neurological recovery assessment before proceeding to the contralateral side, a clinically sound and patient-centred protocol
- Proven efficacy for essential tremor: RF thalamotomy has decades of evidence for tremor abolition in the upper extremity, with immediate intraoperative confirmation of effect
Procedure Details
Step-by-Step Overview
- Pre-operative MRI-based stereotactic planning to identify the Vim thalamic target bilaterally
- Patient positioned in stereotactic frame; pre-procedure neurological baseline documented
- Burr hole created under local anaesthesia; RF electrode advanced to planned thalamic coordinates
- Microelectrode recording performed to physiologically confirm target location
- Test stimulation carried out at low amplitude – patient awake and cooperative for real-time tremor assessment
- Thermal lesion created at confirmed target; immediate cessation of hand tremor observed intraoperatively
- Neurological examination completed before wound closure to confirm deficit-free outcome
- Procedure repeated on contralateral side approximately one year later following same protocol
Procedure Facts
| Procedure | Radiofrequency (RF) Lesioning – Vim Thalamotomy |
| Duration (per side) | Approximately 2 to 3 hours including stereotactic planning |
| Anaesthesia | Local anaesthesia with monitored sedation (patient cooperative during target confirmation) |
| Device / Implant | RF electrode – no permanent implant |
| Approach | Stereotactic burr hole – transcranial |
| Intraoperative Complications | None |
| Hospital Stay | Short stay – 1 night observation per stage |
| Stage 1 | Right hand thalamotomy |
| Stage 2 | Left hand thalamotomy – approximately 12 months after Stage 1 |
| Performing Surgeon | Dr. Gurneet Singh Sawhney, Neurosurgeon in Mumbai |
| Facility | Fortis Hospital, Mulund, Mumbai |
Procedure Details
Stage 1 delivered a dramatic and immediate reduction in right hand tremor, with the patient regaining the ability to eat, drink, and perform basic tasks without assistance within weeks of the procedure. The result was stable and sustained, giving both patient and treating team the confidence to proceed with the left side.
Stage 2 replicated the outcome on the contralateral hand. On follow-up assessment after both procedures, the patient demonstrated bilateral steady hand control with no meaningful residual tremor, fully restored independence in activities of daily living, and no neurological deficits.
Outcomes at a Glance
| Outcome Metric | Result |
| Tremor Control – Right Hand | Complete – immediate intraoperative abolition confirmed |
| Tremor Control – Left Hand | Complete – replicated at Stage 2, one year later |
| Bilateral Functional Outcome | Excellent – steady hand control restored for ADLs |
| Patient Satisfaction | Very high – independence in eating, drinking, and writing regained |
| Neurological Deficits | None |
| Complications | None at either stage |
| Recovery | Smooth – within expected post-RF timeline for both stages |
Patient Feedback
“Before the surgery I could not even drink a glass of water without spilling it everywhere. After the first procedure on my right hand I could not believe the difference – my hand was steady for the first time in years. When I went back for my left hand a year later, the result was exactly the same. I can now eat my meals, write, and go out on my own without worrying. I feel like myself again.”

Post-Procedure Care & Recovery
Instructions Given to Patient
- Rest and restricted activity for 48 hours post-procedure; light supervised ambulation on Day 1
- Prescribed analgesics and anti-oedema medication as clinically indicated
- Head dressing care for burr hole site – keep dry for 72 hours
- Avoid strenuous physical exertion, bending, and heavy lifting for 2 to 3 weeks
- No driving until cleared at follow-up neurological assessment
- Outpatient follow-up at 1 week, 4 weeks, and 3 months post-procedure; annual review thereafter
Recovery Timeline
| Timeframe | What to Expect |
| Day 1 to 3 | Mild headache and site discomfort expected. Tremor abolition typically immediate. Bed rest with supervised movement. |
| Week 1 to 2 | Site healing. Suture check at 1 week. Patient begins using treated hand for simple ADLs. Swelling at burr hole site resolves. |
| Week 4 to 6 | Full return to light daily activities. Neurological review confirms deficit-free status. Functional gains consolidated. |
| Month 3 | Final assessment of tremor status and neurological baseline. Outcome documented. Decision on contralateral side if applicable. |
| 12 Months (Stage 2) | Contralateral procedure scheduled and performed, following the same protocol. Recovery mirrors Stage 1. |
| Post Stage 2 – Month 3 | Full bilateral outcome confirmed. Both hands are stable. Patient discharged to annual review. |
