Treating deep brain lesions has traditionally required large, invasive surgeries that can disrupt healthy brain tissue and prolong recovery. At IGEA Brain, Spine, Pain & Orthopedics, we utilize keyhole craniotomy with Brain Port technology, a minimally invasive approach that allows neurosurgeons to reach deep-seated brain lesions safely and precisely.
A keyhole craniotomy is a minimally invasive surgical approach in which the neurosurgeon creates a small opening in the skull to access the brain. Brain Port technology is a tubular retractor system that gently parts brain tissue along natural pathways rather than cutting through it. This "port" provides a direct corridor to deep lesions, allowing precise removal while minimizing trauma to surrounding structures.
Deep brain lesions, including tumors, cysts, or vascular malformations, can be challenging to access safely. Brain Port technology offers several advantages:
Minimally invasive: Smaller incision and reduced tissue disruption
Preserves healthy brain tissue: The tubular port navigates along natural
tissue planes
Improved visualization: Allows direct access to the lesion through the port
using endoscopic or microscopic guidance
Faster recovery: Patients often experience shorter hospital stays and quicker
return to normal activities
Patients with deep-seated lesions such as:
Brain tumors located in the thalamus, basal ganglia, or ventricular system
Certain types of vascular malformations
Cysts or other lesions that are difficult to reach with traditional open
surgery
Not all lesions are suitable for keyhole access; careful imaging and evaluation are necessary to determine the safest surgical approach.
Advanced imaging is used to plan the safest trajectory to the lesion.
A small craniotomy (typically 2–3 cm) is created.
The Brain Port tube is inserted along the planned pathway, gently displacing
rather than cutting brain tissue.
The lesion is visualized and removed using specialized instruments and
endoscopic or microscopic assistance.
The port is removed, and the small incision is closed.
Patients typically experience less pain and faster recovery than with traditional open craniotomy. Post-operative care includes close neurological monitoring, imaging to confirm lesion removal, and rehabilitation if needed.
