Microsurgery
High-precision surgical procedures using advanced microscope technology for delicate neural structures
Overview
Microsurgery represents the highest level of surgical precision in neurosurgery, using powerful operating microscopes to work on structures measured in millimeters. Dr. Meza received dedicated microsurgery training at Brazil's Federal University of São Paulo — one of Latin America's leading microsurgery programs — where he refined techniques for working with delicate blood vessels, nerve fibers, and brain tissue. This training enables him to perform intricate procedures such as vascular malformation repair, nerve decompression, and tumor resections in areas where millimeters matter. Microsurgical technique is fundamental to achieving the best outcomes in neurosurgery, reducing trauma to healthy tissue and preserving neurological function.
Conditions Treated
- Cerebral aneurysms
- Arteriovenous malformations (AVMs)
- Cavernous malformations
- Cranial nerve tumors (schwannomas, neuromas)
- Complex brain tumors in eloquent areas
- Nerve entrapment syndromes
- Spinal vascular malformations
Our Approach
Dr. Meza operates with high-magnification surgical microscopes that provide illuminated, detailed views of the operative field. This allows for precise dissection around blood vessels, nerves, and functional brain tissue. For vascular lesions, microsurgical clipping or excision techniques are used to eliminate the malformation while preserving normal blood flow. For tumors near critical structures, the microscope allows Dr. Meza to identify and protect the fine boundaries between tumor and healthy tissue. His dedicated training in cerebral white matter fiber anatomy further enhances his ability to safely navigate the brain's internal pathways during complex procedures.
What to Expect
Microsurgical procedures are performed under general anesthesia in a fully equipped operating room. Surgery duration varies significantly depending on the condition — from 2 hours for nerve decompressions to 6 or more hours for complex vascular malformations. Hospital stays typically range from 2 to 7 days depending on the procedure. Recovery varies: nerve decompression patients may return to activities within 2 to 3 weeks, while patients who undergo intracranial vascular procedures may need 4 to 8 weeks. Dr. Meza provides detailed postoperative instructions and follow-up imaging as needed.

Frequently Asked Questions
Microsurgery uses powerful operating microscopes that magnify the surgical field up to 40 times normal vision. This allows the surgeon to work on structures as small as 1 millimeter with extreme precision. It is not a separate type of surgery but a technique that enhances the precision of any neurosurgical procedure.
Microsurgery allows for more precise tissue handling, which typically means less damage to surrounding structures. While the incision size depends on the specific procedure, the precision of microsurgical technique generally results in less unintended tissue trauma and better outcomes.
Conditions involving delicate structures benefit the most — cerebral aneurysms, arteriovenous malformations, tumors near critical brain areas, and nerve entrapment syndromes. Any procedure where preserving millimeters of tissue matters benefits from microsurgical technique.
