Lesionectomy in India

What is Lesionectomy?

A lesionectomy is the targeted microsurgical excision of a well-circumscribed, discrete structural brain lesion causing chronic drug-resistant seizures, while preserving the surrounding healthy eloquent cerebral cortex.

Indications & Common Reasons for Surgery

This advanced neurosurgical intervention is recommended for patients diagnosed with:

• Focal cortical dysplasia (FCD Type I/II) identified on high-resolution 3T epilepsy-protocol MRI.
• Cerebral cavernous malformations (cavernomas) producing persistent epilepsy.
• Benign neuroepithelial tumors such as dysembryoplastic neuroepithelial tumors (DNET) and gangliogliomas.
• Post-traumatic or ischemic localized gliotic epileptogenic scars.

Surgical Techniques & Precision Modalities

Frameless neuronavigation coupled with intraoperative electrocorticography (ECoG) to delineate and excise both the core lesion and the surrounding irritative epileptogenic zone. The procedure is performed in advanced modular operating suites equipped with 3D neuronavigation, high-definition intraoperative microscopes, neuro-endoscopy, and real-time electrophysiological monitoring to preserve vital neurological functions.

Postoperative Care & Recovery Timeline

Hospitalization of 2 to 4 days, with exceptional seizure-freedom rates (>80%) and low risk of new neurological deficits. Patients benefit from specialized neuro-intensive care, personalized neuro-rehabilitation, and multidisciplinary follow-up to support optimal long-term functional outcomes.

Key Clinical Benefits

• Targeted, maximal safe anatomical correction and pathology excision.
• Protection of eloquent brain areas and essential cranial nerve pathways.
• Significant alleviation of neurological symptoms and prevention of secondary brain injury.
• Accelerated recovery supported by modern microsurgical and minimally invasive techniques.
