A brain tumor diagnosis affects the entire family. Dr. Narula specializes in maximum-safe-removal philosophy: aggressive tumor treatment while preserving speech, movement, vision, memory and personality. Using microscopy, neuronavigation and intraoperative monitoring, surgery protects both tumor control and quality of life.
Understanding Brain Tumors
Brain tumors can be primary (starting in the brain) or secondary (spreading from cancer elsewhere). They can be benign (non-cancerous) or malignant. Size, location and type determine whether surgery is needed. Even benign tumors can cause problems if they press on vital areas controlling speech, movement or vision.
Surgical Philosophy: Maximum Safe Removal
The goal is not just removing tumor, but removing the most tumor possible while protecting brain function. This means identifying where speech, movement, vision and memory live in your brain, then planning surgery to work around these areas. A tumor near motor cortex requires different techniques than one in silent cortex.
Pre-Operative Planning and Imaging
Advanced imaging maps your specific brain anatomy. MRI with contrast shows tumor extent. DTI (diffusion tensor imaging) reveals motor and language pathways. fMRI (functional MRI) shows which brain areas control movement and speech. This mapping guides surgical planning before you even go to the OR.
Surgical Techniques: Microscopic vs Endoscopic
Microscopic surgery uses high magnification and precision instruments through a brain window. Endoscopic surgery uses cameras and narrow corridors, useful for deep or ventricular tumors. The choice depends on location, size and access. Most brain tumors use microscopic surgery; selected deep tumors use endoscopy.
Intraoperative Neuromonitoring
During surgery, electrodes monitor motor and language pathways in real-time. If a probe touches an important area, you receive feedback before damage occurs. This allows safe, maximum removal. Some patients remain awake during surgery (awake craniotomy) when the tumor is in eloquent areas, allowing continuous verbal feedback.
Pathology and Tumor Grading
Tissue removed during surgery goes to pathology for analysis. Results determine tumor grade (aggressiveness), type and whether further treatment (chemotherapy, radiation) is needed. Pathology results come back within days and guide post-operative planning.
Recovery and Hospital Course
Most patients wake up immediately after surgery. Hospital stay is typically 1-3 days. Neurological checks continue frequently. Some swelling (brain edema) is expected and managed with medications. Early mobilization prevents complications. Pain is usually moderate and well-controlled.
Post-Operative Follow-Up and Imaging
MRI brain is done within 24-48 hours to show extent of resection and check for complications. Follow-up scans assess healing and monitor for recurrence. Radiation therapy or chemotherapy decisions are made based on pathology, grade and extent of resection.
Radiation and Chemotherapy Planning
Some tumors benefit from radiation or chemotherapy after surgery. High-grade gliomas usually get both. Lower-grade tumors may be observed. Coordination with oncology ensures a unified treatment plan and smooth transition from surgery to other therapies.
Long-Term Outlook and Follow-Up
Brain tumor prognosis depends on type, grade, extent of removal and patient age. Some patients achieve long remission; others need ongoing treatment. Regular imaging and neurology follow-up monitor stability. Many patients return to work, driving and normal activities within weeks to months.
