Radiosurgery (Gamma Knife) in Hyderabad
Stereotactic radiosurgery (SRS), often known as Gamma Knife, delivers highly focused radiation to selected brain targets without an incision. It's used for certain small brain tumors, metastases, vestibular schwannomas, arteriovenous malformations (AVMs), and trigeminal neuralgia. Suitability depends on size, location, diagnosis, and overall health.
Who may benefit
- Brain metastases (selected sizes and number)
- Benign tumors such as vestibular schwannoma and some meningiomas
- Arteriovenous malformations (AVMs) in selected cases
- Trigeminal neuralgia (nerve root entry zone target)
We confirm diagnosis, size, and exact location with imaging and multidisciplinary review to determine if SRS is appropriate.
Planning and procedure
- Imaging (MRI ± CT) for precise target mapping
- Frame or frameless positioning system
- Outpatient, non-incisional treatment; actual beam-on time varies by target
- Post-procedure observation and discharge instructions
Benefits and risks
Potential Benefits
- No incision, minimal downtime for most patients
- Outpatient or day-care workflow
- Option for lesions in deep or eloquent locations not amenable to open surgery
Risks/Limitations
- Delayed response: tumor control may take months; TN pain relief may take weeks
- Edema/swelling risk requiring medications; rare radiation necrosis
- Not suitable for all lesion sizes/types; may require staged or alternative therapy
Recovery and follow-up
- Most patients resume light activity within 24–48 hours
- MRI follow-up at defined intervals to track response
- TN patients receive a taper plan for medicines as pain control evolves
When SRS may not be preferred
- Large tumors needing rapid decompression or causing mass effect
- Lesions requiring tissue diagnosis (biopsy/resection)
- TN cases where MVD is safer/better aligned with goals and MRI shows vascular compression
Costs and insurance (Hyderabad)
- Typically covered for indicated cases after pre-authorization
- Written estimate after evaluation and imaging review
