Overview
Surgery is not the first option in treating any cause of tremor. It is applied once non-pharmacological and pharmacological therapy fails. Botulinum neurotoxin injections, thalamotomy, deep brain stimulation, magnetic resonance-guided focused ultrasound, and radio-surgical gamma knife thalamotomy are the most common interventional procedures to treat tremors.
Surgery
- Botulinum neurotoxin injections:
- Thalamotomy: [2]
- Helpful in medication-resistant essential tremor, cerebellar tremor, or Parkinson's disease related tremor.
- Tremor is permanently treated by creating lesions in the thalamus responsible for causing tremors.
- Most common side effects are dysarthria, cognitive impairment, and imbalance.
- It is an invasive procedure.
- Deep brain stimulation: [3]
- Parkinson's disease and essential tremor may benefit from deep brain stimulation.
- In this non-invasive procedure, electrodes are implanted to send high-frequency electrical signals to the thalamus, substantia nigra, or globus pallidus. The downside of deep brain stimulation is the expense, and long-term benefits are not established. It is reversible.
- Magnetic resonance-guided focused ultrasound (MRgFUS): [4]
- Noninvasive thalamotomy procedure uses thermal ablation.
- Used in severe medication-resistant essential tremor or Parkinsonian tremor.
- Most of the side effects reported did not last more than three months.
- Radio-surgical gamma knife thalamotomy: [5]
- It is found to be safe if done unilaterally.
- Optimum dose from 130 to 150Gy is well tolerated.
- Most common side effects are mild contralateral numbness and transient hemiparesis.
