Gamma Knife Radiosurgery in Hyderabad
— Precise Non-Surgical Brain Treatment at KIMS

Gamma Knife is not surgery in any conventional sense. No incision is made in the scalp. The skull is not opened. The brain is not touched by any instrument. The term “surgery” in radiosurgery refers to the precision of the treatment — the ability to target a specific volume within the brain with sub-millimetre accuracy — not to any surgical procedure being performed. The treatment uses 192 beams of gamma radiation, each individually too weak to cause significant damage to the tissue it passes through, that converge from different angles to meet at the target. At the convergence point, the accumulated dose is high enough to damage tumour DNA and destroy abnormal blood vessels — while the surrounding brain, traversed by each individual beam but never experiencing the full converging dose, is largely spared. The result: a treatment that achieves what surgery achieves — destroying a target within the brain — without cutting anything. Call 040-44885000.

The suitability of Gamma Knife depends on five main factors: (1) Tumour size: Gamma Knife is most effective for tumours up to approximately 3–3.5 cm in diameter. Larger tumours are generally better managed by surgery, though staged radiosurgery or hypofractionated (multi-session) Gamma Knife can be used in selected cases. (2) Tumour location: Gamma Knife is particularly well-suited to tumours in surgically difficult locations — the brainstem, deep basal ganglia, cavernous sinus, and skull base — where the precision of radiosurgery allows treatment that surgery could not achieve without unacceptable risk. (3) Need for tissue diagnosis: if the tumour type is not established and pathological confirmation is needed to guide treatment, surgery or biopsy is needed before Gamma Knife. (4) Mass effect: if the tumour is causing significant brain compression or hydrocephalus, surgical decompression must precede or replace Gamma Knife. (5) Number of metastases: Gamma Knife is highly effective for up to 10 brain metastases (some centres treat more); whole-brain radiation or systemic therapy may be considered for higher numbers. At KIMS, Gamma Knife eligibility is determined by the multidisciplinary tumour board. Call 040-44885000.

Yes — in many cases, and this is one of Gamma Knife's most important clinical roles. The term “inoperable” usually means one of three things: the tumour is in a location that cannot be accessed surgically without causing unacceptable permanent neurological damage (brainstem, basal ganglia, cavernous sinus) · the patient has medical conditions (heart disease, respiratory disease, coagulopathy) that make general anaesthesia and surgery too risky · the patient has already undergone maximum surgical resection and residual or recurrent tumour remains. In all three situations, Gamma Knife can often provide effective treatment: it accesses deep and surgically inaccessible locations as easily as superficial ones, because radiation beams penetrate the skull without any surgical approach corridor · It does not require general anaesthesia · It can treat post-operative tumour residual with high precision. Not all inoperable tumours are suitable for Gamma Knife — very large, diffuse infiltrating tumours are not appropriate candidates. The KIMS team can review your imaging and advise specifically.

Yes — KIMS Hyderabad is a referral centre for Gamma Knife radiosurgery for patients across Telangana, Andhra Pradesh, and the surrounding states. Patients from Vijayawada, Visakhapatnam, Tirupati, Nellore, Kurnool, Warangal, and Karimnagar regularly travel to KIMS specifically for Gamma Knife treatment that is not available at their local hospitals. The typical process for out-of-Hyderabad patients: (1) Send your MRI and case summary to neuroscience@kimshospitals.com or call 040-44885000 — the team will review your imaging and advise whether Gamma Knife is appropriate for your case and schedule you. (2) The Gamma Knife treatment itself is a single-day procedure. You arrive in the morning, the treatment is completed by mid-afternoon, and most patients travel home the same evening or the following morning. (3) Follow-up MRI scans are scheduled at 3, 6, and 12 months and can be performed at your local hospital, with the images reviewed remotely by the KIMS team. The single-day nature of Gamma Knife makes it particularly practical for patients travelling from outside Hyderabad. Call 040-44885000.
