Overview
Gamma Knife radiosurgery delivers focused radiation to deep or delicate brain targets without an incision—ideal for small metastases, vestibular schwannomas, some meningiomas, and selected trigeminal neuralgia cases.
When is Radiosurgery Used?
- Deep or surgically challenging lesions
- Patients unfit for open surgery
- Adjuvant therapy after microsurgery
Planning & Workflow
High-resolution MRI/CT imaging, frame-based or mask-based immobilization, and dose planning with stereotactic software. Outpatient procedure; most patients go home the same day.
Risks & Considerations
- Radiation-related swelling (usually transient)
- Rare cranial nerve effects depending on target
- Follow-up imaging to confirm response
Recovery
Most patients resume light activity within 24–48 hours. Clinical and imaging follow-up at defined intervals.
Frequently Asked Questions
Is Gamma Knife painful?
It is generally painless. Some patients feel brief pressure with frame placement; mask-based immobilization avoids pinning.
How soon do results appear?
Tumour control is assessed over months on imaging; trigeminal neuralgia pain relief can occur within weeks for many patients.
