Summary
Deep brain stimulation (DBS) and thalamotomy offer similar tremor control rates. DBS provides greater flexibility in managing recurrence and complications, making it a potentially superior option despite higher costs.
Area of Science:
- Neurosurgery
- Neurology
- Medical Technology
Background:
- Deep brain stimulation (DBS) is increasingly used for tremor control at the same anatomical sites as thalamotomy.
- A direct comparison between DBS and thalamotomy for tremor management is warranted.
Purpose of the Study:
- To compare the efficacy and safety of DBS versus thalamotomy for tremor control.
- To evaluate outcomes in patients with Parkinson's disease (PD) and essential tremor (ET).
Main Methods:
- Retrospective analysis of 19 DBS implants and 26 thalamotomies performed between 1990 and 1996.
- Patients had PD or ET and were followed for at least 3 months.
Main Results:
- Complete tremor abolition occurred in 42% of both groups; near abolition in 79% (DBS) and 69% (thalamotomy).
- Tremor recurrence was lower after DBS (5%) than thalamotomy (15%), with DBS recurrence managed by parameter adjustment.
- Adverse events like ataxia and dysarthria were more frequent after thalamotomy (42%) than DBS (26%), and often manageable with DBS parameter adjustments.
Conclusions:
- DBS offers superior tremor control flexibility and complication avoidance compared to thalamotomy.
- Thalamotomy may require re-operation for recurrence, while DBS allows for parameter adjustments.
- While DBS involves equipment costs and ongoing management, its adaptability enhances patient outcomes.
