Brain Tumor Surgery
Precision microsurgical resection to maximize tumor removal while preserving brain function
Overview
Brain tumor surgery is one of the most demanding procedures in neurosurgery, requiring precise knowledge of neuroanatomy and advanced microsurgical skills. Dr. Meza performs craniotomies and microsurgical resections for a range of intracranial tumors, including gliomas, meningiomas, pituitary adenomas, and metastatic lesions. Each case begins with a thorough evaluation using MRI and CT imaging, followed by a surgical plan designed to achieve maximum tumor removal while minimizing risk to surrounding brain tissue. Dr. Meza's specialized training in cerebral white matter fiber dissection at Brazil's Federal University of São Paulo allows him to navigate the brain's complex fiber pathways with greater precision, reducing the risk of postoperative neurological deficits.
Conditions Treated
- Gliomas (astrocytomas, oligodendrogliomas, glioblastomas)
- Meningiomas
- Pituitary adenomas
- Brain metastases
- Acoustic neuromas (vestibular schwannomas)
- Epidermoid and dermoid cysts
- Colloid cysts
Our Approach
Dr. Meza uses microsurgical techniques with high-powered surgical microscopes to operate on brain tumors through precisely planned craniotomies. His approach prioritizes maximum safe resection — removing as much tumor as possible while preserving eloquent brain areas responsible for speech, movement, and sensation. Preoperative planning includes detailed MRI analysis to map the tumor's relationship to critical structures. For patients with tumors near functional brain areas, careful intraoperative technique and anatomical expertise help guide safe boundaries of resection.
What to Expect
Your journey begins with a comprehensive consultation where Dr. Meza reviews your imaging studies, discusses your diagnosis, and explains the surgical plan. Surgery is performed under general anesthesia, and duration varies from 2 to 6 hours depending on the tumor's size and location. After surgery, you will be monitored in the intensive care unit for 24 to 48 hours. Most patients spend 3 to 5 days in the hospital. Recovery at home typically takes 4 to 8 weeks, with follow-up imaging and appointments to monitor your progress. Dr. Meza coordinates with oncologists when adjuvant therapy is needed.

Frequently Asked Questions
No. Many brain tumors are benign (non-cancerous), such as meningiomas and pituitary adenomas. However, even benign tumors may require surgery if they compress brain structures or cause symptoms like headaches, vision changes, or seizures. Dr. Meza will explain the nature of your specific tumor and the recommended treatment.
All surgery carries risks, including infection, bleeding, and reactions to anesthesia. Brain tumor surgery carries additional risks related to the tumor's location, such as changes in speech, motor function, or vision. Dr. Meza's microsurgical training and anatomical expertise are focused on minimizing these risks through precise surgical planning.
Most patients can resume light daily activities within 2 to 4 weeks. Return to work depends on your occupation and recovery — typically 4 to 8 weeks for desk work. Strenuous physical activity should be avoided for at least 6 to 8 weeks. Dr. Meza will provide a personalized recovery timeline.
