Lesionectomy is a specialised brain surgery designed to remove abnormal tissue causing seizures or other neurological issues, especially in patients who do not respond well to medications. It targets specific brain lesions identified through detailed imaging and diagnostic evaluations.
The procedure involves opening a small part of the skull (craniotomy) to access and carefully remove the lesion, with the help of advanced tools like brain mapping and surgical navigation to avoid damage to healthy brain areas.
Lesionectomy can significantly reduce or stop seizures and may also improve cognitive and functional abilities. Recovery depends on the lesion’s location and complexity, and patients are often supported with short-term rehabilitation and ongoing medical follow-up.
- Frequent or uncontrolled seizures, especially if medications are ineffective
- Neurological symptoms such as weakness, vision changes, speech difficulties, or memory problems
- Changes in personality or cognition
- Brain imaging (MRI, CT) that shows a lesion with unclear or suspicious features
- Neuroimaging: MRI, PET, or CT scans to locate the lesion
- EEG monitoring: To map seizure activity and confirm the lesion as the source
- Neuropsychological testing: To assess memory, language, and cognitive functions
- Functional MRI or brain mapping: To identify areas responsible for vital functions like speech or movement
- Medication review: Some drugs may be paused or adjusted before surgery
- Fasting: Usually required 6–8 hours before the procedure
- Anaesthesia: The patient is placed under general anaesthesia.
- Craniotomy: A portion of the skull is carefully opened to access the brain.
- Navigation and Mapping: Advanced imaging and intraoperative brain mapping guide the surgeon to locate the lesion precisely.
- Lesion Removal: The abnormal tissue is removed, taking care to avoid surrounding healthy or functional areas.
- Closure: The bone flap is replaced, and the scalp is sutured.
- Infection
- Bleeding
- Brain swelling
- Neurological deficits (speech, memory, or motor issues, depending on location)
- Seizures after surgery
- Cerebrospinal fluid leakage
- Anesthesia-related complications
- Seizure reduction or elimination, especially in drug-resistant epilepsy
- Improved quality of life, cognitive function, and independence
- Minimal disruption to the surrounding brain tissue when precisely targeted
- Increased effectiveness of medications post-surgery, if still required
- It can sometimes eliminate the need for lifelong anti-seizure medication
- Patients are initially monitored in the ICU and then transferred to a regular neurology unit.
- Headaches, fatigue, or confusion are common during early recovery.
- Physical, occupational, or speech therapy may be needed depending on outcomes.
- Most patients resume light activities in 2 to 4 weeks and return to work or school within 6 to 8 weeks.
- Follow-up includes neuroimaging, EEGs, and ongoing neurology consultations.

+99Process Involved for Lesionectomy
- Preoperative Evaluation: This includes a neurological exam, EEG, MRI, and sometimes intracranial monitoring to localise the lesion.
- Surgical Planning: Advanced imaging and brain mapping are used to plan a safe and precise lesion removal.
- Surgery (Lesionectomy): The identified brain lesion is surgically removed through a craniotomy.
- Intraoperative Monitoring: Brain function is continuously monitored to protect vital areas of the brain.
- Postoperative Care: Includes observation in the ICU, pain management, and neurological assessments.
- Rehabilitation: This may involve physical, occupational, or speech therapy, depending on the specific brain area affected.
- Follow-up and Monitoring: Conduct long-term follow-up, including imaging and seizure monitoring, to assess outcomes and evaluate the effectiveness of treatment.
