Some brain conditions require a sample, drainage, or a permanent diversion route — but not necessarily a large open operation. Stereotactic and minimally invasive techniques allow these goals to be achieved through very small openings, guided by precise imaging.

Conditions treated

• Brain biopsy — a thin needle is guided to exactly the right spot to take a tissue sample, establishing a definitive diagnosis (tumour type, infection, inflammation) so the correct treatment can be planned.
• Brain abscess — pus collections deep in the brain can be drained accurately through a small burr hole, clearing the infection with minimal disruption to surrounding tissue.
• CSF shunt placement — when cerebrospinal fluid builds up (hydrocephalus) and endoscopic treatment is not suitable, a shunt is placed to divert fluid safely and relieve pressure.

How it works

A stereotactic frame or frameless neuronavigation system is used together with pre-operative MRI or CT scanning to plan the exact trajectory before the procedure begins. This allows the surgeon to reach a precise target — sometimes just a few millimetres across — through the smallest necessary opening in the skull.

Why Dr. Mazen Agour

Dr. Agour uses stereotactic techniques as part of his broader neurosurgical practice, applying them to diagnosis and treatment where a minimal-access approach is appropriate. Each case is assessed individually to decide whether this approach offers an advantage over alternatives.
