Traditional neurosurgery may require a relatively large opening to reach a condition located deep within the brain or skull base. Advances in neuroendoscopy now allow surgeons to perform selected procedures through smaller surgical corridors using specialised cameras and instruments. Apollo Adlux Hospital, Kochi, is equipped with Karl Storz Endoscopic Systems for minimally invasive brain, ventricular and skull-base procedures. Karl Storz provides neuroendoscopic solutions for intraventricular, cranial and skull-base conditions, combining specialised imaging systems and surgical instruments.

What Is Neuroendoscopy?

Neuroendoscopy is a surgical technique in which a thin instrument known as an endoscope is used to view and access structures within the brain, ventricles, skull base or spine. An endoscope typically includes:

• A high-resolution camera
• An illumination source
• A narrow rigid or flexible tube
• Channels for specialised surgical instruments
• Connection to a video display system

The camera transmits enlarged images to a monitor, enabling the neurosurgeon to operate through a small opening or a natural anatomical passage.

Types of Neuroendoscopic Procedures

Neuroendoscopy may be performed using several approaches.

Intraventricular Neuroendoscopy

This technique accesses the fluid-filled spaces within the brain known as ventricles. It may be used to treat selected forms of hydrocephalus, cysts or intraventricular tumours.

Endoscopic Endonasal Surgery

The surgeon reaches the skull base through the nose and nasal passages, avoiding an external facial incision. It may be considered for selected:

•            Pituitary tumours
•            Skull-base tumours
•            Cerebrospinal fluid leaks
•            Cysts near the pituitary gland
•            Lesions involving the sphenoid sinus or central skull base

Endoscope-Assisted Microsurgery

An endoscope may be used together with a surgical microscope to view areas that are difficult to see directly.

Endoscopic Spine Surgery

Selected spinal disorders may be treated through small incisions using an endoscopic camera and specialised instruments.

Neuroendoscopy for Hydrocephalus

Hydrocephalus occurs when cerebrospinal fluid accumulates within the brain’s ventricles, potentially increasing pressure. In selected patients, a procedure called endoscopic third ventriculostomy may be performed. The surgeon creates a small opening to allow cerebrospinal fluid to flow through an alternative pathway. The suitability of this procedure depends on:

•            Cause of hydrocephalus
•            Patient’s age
•            Ventricular anatomy
•            Previous treatments
•            Presence of infection or bleeding
•            Neurosurgeon’s assessment

Some patients may still require a cerebrospinal fluid shunt.

Endoscopic Skull-Base Surgery

The skull base contains several important nerves, arteries and glands. Certain lesions in this region can be approached through the nose using an endoscopic endonasal technique. This may provide a direct pathway to selected midline skull-base conditions. Potential benefits in suitable cases may include:

•            No large external scalp or facial incision
•            Direct visual access to the lesion
•            Reduced manipulation of the brain in selected procedures
•            Wide-angle visualisation
•            Potentially shorter recovery in some patients
•            Collaboration between neurosurgery and ENT teams

The approach is not suitable for every skull-base tumour. The location, size and relationship to surrounding structures must be carefully assessed.

Conditions That May Be Treated with Neuroendoscopy

Karl Storz Endoscopic Systems may support selected procedures involving:

•            Obstructive hydrocephalus
•            Pituitary adenomas
•            Skull-base tumours
•            Intraventricular cysts
•            Colloid cysts
•            Selected brain tumours
•            Cerebrospinal fluid leaks
•            Arachnoid cysts
•            Ventricular bleeding or obstruction
•            Selected spinal conditions

Treatment decisions are based on MRI or CT findings and a detailed neurological assessment.

Potential Benefits of Endoscopic Neurosurgery

Depending on the procedure, possible benefits include:

•            Smaller surgical openings
•            Enhanced visualisation of deep structures
•            Wide-angle viewing
•            Access through natural anatomical corridors
•            Less disturbance of surrounding tissue in selected cases
•            Reduced postoperative discomfort
•            Shorter hospital stay in some patients
•            Earlier recovery compared with more extensive approaches

These benefits cannot be guaranteed and vary according to the disease and procedure.

Risks of Neuroendoscopic Surgery

Although neuroendoscopy is minimally invasive, it remains a major surgical procedure. Potential risks may include:

•            Bleeding
•            Infection
•            Cerebrospinal fluid leakage
•            Injury to nerves or blood vessels
•            Hormonal disturbances in selected pituitary procedures
•            Visual changes
•            Failure of the procedure
•            Need for additional or open surgery

The neurosurgeon will explain risks specific to the planned procedure.
