What is Glioblastoma?
Glioblastoma is a highly aggressive and malignant brain tumor that originates in the brain’s glial cells. It grows rapidly and infiltrates surrounding brain tissue, making complete removal challenging. As one of the most difficult brain tumors to treat, glioblastoma requires a comprehensive approach that includes surgery, radiation therapy, and chemotherapy. Early intervention is crucial to managing symptoms and improving quality of life.
At California Neurosurgical Specialists, we understand how scary this condition can be. That’s why we take a compassionate approach and leverage the expertise of Dr. Benet, who is known as the best glioblastoma surgeon in Los Angeles. He performs the most advanced glioblastoma resection available, using precision microsurgical techniques to remove as much of the tumor as possible while preserving neurological function.

How Do I Know If I Have Glioblastoma?
Glioblastoma symptoms depend on the tumor’s size and location but may include:
Persistent and worsening headaches
Seizures or convulsions
Nausea and vomiting
Cognitive decline, including memory loss and difficulty concentrating
Weakness or numbness in the limbs
Speech difficulties or vision changes
Personality or mood changes
If you experience any of these symptoms, a comprehensive neurological evaluation and imaging tests such as MRI or CT scans can help confirm a diagnosis.

What to Expect During Glioblastoma Surgery
Glioblastoma resection is a highly specialized procedure that requires precision and advanced technology. Dr. Benet — the best brain tumor surgeon in Los Angeles — follows a meticulous approach to ensure the best possible outcome. Here’s what to expect:
1.
Pre-Surgical Preparation
Comprehensive Evaluation: MRI, fMRI, and CT scans map the tumor and surrounding structures.
Neurosurgical Planning: Advanced neuronavigation and intraoperative imaging guide the safest surgical approach.
Pre-Operative Consultation: Dr. Benet discusses the procedure, risks, benefits, and recovery expectations.
2.
During Surgery
Anesthesia & Monitoring: The procedure is performed under general anesthesia with continuous monitoring of brain activity and vital signs.
Intraoperative Mapping: Awake brain mapping (if needed) and neurophysiological monitoring protect critical functions.
Tumor Resection: Microsurgical techniques and fluorescence-guided imaging remove as much of the tumor as safely as possible.
Intraoperative Imaging: Real-time imaging confirms tumor removal before closing the surgical site.
3.
Post-Surgical Recovery
ICU Monitoring: Patients are closely observed for the first 24-48 hours.
Neurological Assessment: Doctors evaluate cognitive and motor function for rehabilitation needs.
Pain & Symptom Management: Medications and steroid therapy help control discomfort and swelling.
Hospital Stay & Follow-Up: Most patients stay for several days before discharge. Follow-up imaging and additional treatments, such as radiation and chemotherapy, are scheduled as needed.

Glioblastoma Surgical Outcomes & Experience
Glioblastoma requires urgent, coordinated care and a surgical strategy focused on maximal safe tumor removal. In treated high-grade GBM cases, Dr. Benet reports >90% survival beyond 18 months. His operative background includes approximately 219 brain tumor resections and approximately 514 craniotomies (all types) across residency training and independent practice. For elective/scheduled cases, he reports 0 operative mortality, and in independent practice, a surgical complication rate (cumulative through December 2025) below 2% across cases. Treatment recommendations are tailored to imaging findings, tumor location, neurologic status, and the overall treatment plan.
Frequently asked Questions

Is glioblastoma curable?
a.
Currently, glioblastoma is not considered curable, but aggressive treatment can extend survival and improve quality of life.
How long is the recovery after glioblastoma surgery?
a.
Recovery varies depending on tumor location and patient health. Most patients remain in the hospital for a few days post-surgery and may require rehabilitation to regain neurological function.
Will I need additional treatments after surgery?
a.
Yes, glioblastoma treatment typically includes radiation therapy and chemotherapy following surgery to target remaining tumor cells.
