Craniotomy Brain Surgery in Bangalore: What to Expect
Understanding Craniotomy: The Most Common Open Brain Surgery
If your doctor has recommended a craniotomy, it is natural to feel anxious. The word itself sounds alarming. But a craniotomy is a well-established, commonly performed surgical procedure — and understanding exactly what it involves can help reduce fear and help you prepare.
This guide explains what a craniotomy is, why it is performed, what surgery and recovery involve, and what it costs in Bangalore.
What Is a Craniotomy?
A craniotomy is a surgical procedure in which a section of the skull (the bone flap) is temporarily removed to allow the neurosurgeon to access the brain. After the brain surgery is completed, the bone flap is replaced and secured with small titanium plates and screws.

A craniotomy is not a diagnosis — it is a surgical approach. It is used to treat many different brain conditions, including tumours, aneurysms, blood clots, and epilepsy. According to the American Association of Neurological Surgeons (AANS), craniotomy is one of the most frequently performed neurosurgical procedures worldwide.
Why Is a Craniotomy Performed?
A craniotomy may be recommended for:
- Brain tumours: To remove or biopsy a tumour (meningioma, glioma, metastasis)
- Brain aneurysm clipping: To place a metal clip across the neck of a bulging blood vessel to prevent rupture
- Intracerebral haemorrhage: To remove a blood clot that is pressing on the brain
- Arteriovenous malformation (AVM): To remove an abnormal tangle of blood vessels
- Epilepsy surgery: To remove the brain tissue causing seizures
- Brain abscess: To drain an infection in the brain
- Traumatic brain injury: To relieve pressure from swelling or bleeding after a head injury
Symptoms That May Lead to Craniotomy
Symptoms vary depending on the underlying condition, but may include:
- Persistent headaches: Especially those that are new, worsening, or worse in the morning
- Seizures: New-onset seizures in an adult always require investigation
- Weakness or numbness: On one side of the body
- Speech or language problems: Difficulty finding words or understanding speech
- Vision changes: Double vision, blurred vision, or loss of peripheral vision
- Personality or behaviour changes: Unexplained mood changes or confusion
When to see a doctor immediately: Sudden severe headache ("thunderclap headache"), loss of consciousness, or rapidly worsening neurological symptoms require emergency evaluation.
Causes and Risk Factors
The need for a craniotomy is determined by the underlying brain condition. Risk factors for the conditions that require craniotomy include:
- Age (brain tumours and aneurysms are more common with age)
- Family history of brain tumours or aneurysms
- Previous radiation to the head
- Smoking and hypertension (increase aneurysm risk)
- Genetic conditions (neurofibromatosis, tuberous sclerosis)
Diagnosis Before Craniotomy
- MRI brain with contrast: The primary imaging tool — shows tumour size, location, and relationship to critical brain structures
- CT scan: Used in emergencies (bleeding, trauma) and for surgical planning
- MR angiography / CT angiography: Maps blood vessels for aneurysm or AVM surgery
- Functional MRI (fMRI): Maps speech and motor areas to plan safe surgical approach
- PET scan: Assesses tumour metabolism and helps distinguish tumour from radiation necrosis
- Biopsy: May be performed before or during craniotomy to confirm diagnosis
Surgery: What to Expect
Before Surgery
Pre-operative assessment includes MRI review, blood tests, ECG, and anaesthesia consultation. Steroid medications (dexamethasone) are often started before surgery to reduce brain swelling. Blood thinners must be stopped 7–10 days before. You will be asked not to eat or drink for 8 hours before surgery.
During Surgery
You will receive general anaesthesia. Your head will be fixed in a special frame to keep it perfectly still. The surgeon makes an incision in the scalp, removes the bone flap, and uses a surgical microscope or neuronavigation system to access the target area. The procedure is performed with great precision to avoid damaging surrounding brain tissue. After completing the procedure, the bone flap is replaced and secured. Surgery typically takes 3–8 hours depending on the complexity.
After Surgery
You will spend 1–2 days in the ICU for close monitoring, then move to a regular ward. Total hospital stay is typically 5–10 days. Pain is managed with medications. A CT scan is performed after surgery to confirm the result.
Recovery and Rehabilitation
Week 1: Rest in hospital and at home. Fatigue is normal and expected. Avoid screens, reading, and strenuous activity.
Weeks 2–4: Gradual return to light activities. Physiotherapy and speech therapy begin if needed.
Months 1–3: Most patients return to desk work. Driving is typically restricted for 3–6 months (and until seizure-free if epilepsy surgery was performed).
Month 6+: Full recovery varies by condition and extent of surgery. Some patients recover completely; others may have lasting neurological changes depending on the location of the surgery.
Red flags: Fever, wound redness or discharge, new or worsening headache, seizures, or any new neurological symptoms — contact your surgical team immediately.
Cost of Craniotomy in Bangalore
| Hospital Tier | Estimated Cost (INR) | What's Included |
|---|---|---|

Choosing a Hospital in Bangalore for Craniotomy
- Neurosurgery volume: Hospitals performing 500+ neurosurgical procedures per year have significantly better outcomes.
- Neuronavigation and intraoperative imaging: Advanced technology allows more precise surgery and reduces the risk of damaging healthy brain tissue.
- Dedicated neurointensive care unit (Neuro-ICU): Essential for post-operative monitoring.
- Multidisciplinary tumour board: For brain tumour cases, a team that includes a neurosurgeon, neuro-oncologist, radiation oncologist, and pathologist gives the best outcomes.
- NABH accreditation: National quality and safety standard.

Frequently Asked Questions
Is a craniotomy a major surgery?
Yes. Craniotomy is a major surgical procedure that requires general anaesthesia, a hospital stay of 5–10 days, and a recovery period of several weeks to months. However, it is a well-established procedure performed routinely at experienced neurosurgery centres.
Will I be awake during a craniotomy?
Most craniotomies are performed under general anaesthesia. However, an "awake craniotomy" is sometimes used when the surgery is near speech or motor areas — the patient is kept awake during part of the procedure to allow real-time testing of brain function. This is not painful; the brain itself has no pain receptors.
How long does recovery take after craniotomy?
Recovery varies by condition and complexity. Most patients return to light activities within 4–6 weeks. Full recovery can take 3–12 months. Your neurosurgeon will give you a personalised timeline.
Will I have a visible scar after craniotomy?
The scalp incision is designed to be hidden within the hairline where possible. Some hair may be shaved around the incision site. Hair typically regrows within 3–6 months.
What are the risks of craniotomy?
Risks include infection, bleeding, brain swelling, seizures, stroke, and neurological deficits. The specific risks depend on the location of the surgery and the underlying condition. Your neurosurgeon will discuss all risks before you consent.
Is craniotomy covered by insurance in India?
Yes. Craniotomy is covered under most private health insurance plans, CGHS, and Ayushman Bharat (PM-JAY). Pre-authorisation is typically required for planned procedures.
