Endoscopic neurosurgery

Endoscopic neurosurgery is a modern minimally invasive surgical approach that uses endoscopic instruments to treat diseases of the brain and spinal cord. This technique allows complex operations to be performed with minimal damage to surrounding tissues.

Advantages of endoscopic neurosurgery

1. Minimally invasive approach. Small incisions reduce tissue trauma.
2. Shorter rehabilitation period. Patients return to normal daily activities more quickly.
3. High precision. The endoscope provides a magnified and highly detailed view of the surgical field.
4. Reduced risk of complications. Blood loss and injury to healthy structures are minimized.
5. Better cosmetic outcome. Scarring is less noticeable.

Main areas of application

1. Brain disorders. Removal of tumors (for example, pituitary adenomas). Treatment of brain cysts. Endoscopic third ventriculostomy (for the treatment of hydrocephalus).
2. Spinal pathologies. Removal of intervertebral disc herniations. Treatment of cysts and tumors of the spinal cord.
3. Traumatic brain injuries. Evacuation of intracranial hematomas.
4. Neurovascular diseases. Treatment of aneurysms and arteriovenous malformations.
5. Skull base pathologies. Removal of tumors through the nasal passages (endoscopic transnasal surgery).

Equipment and techniques

1. Endoscope. A thin tubular device with a camera and light source that provides an enlarged image on a monitor.
2. Instruments. Microsurgical tools designed for manipulation through small access points.
3. Navigation systems. 3D navigation technologies for precise localization of pathology.
4. Additional equipment. Ultrasonic or laser devices to further minimize tissue trauma.

Examples of endoscopic procedures

1. Endoscopic transnasal surgery. Access through the nasal passages to remove pituitary adenomas and skull base tumors.
2. Endoscopic ventriculostomy. Treatment of hydrocephalus by creating an alternative pathway for cerebrospinal fluid drainage.
3. Endoscopic removal of intervertebral disc herniation. Minimally invasive decompression of nerve roots.
4. Removal of brain cysts and tumors. Treatment of third ventricle cysts, ependymomas, and other neoplasms.
5. Endoscopic evacuation of hematomas. Removal of intracranial hemorrhages after trauma or stroke.

Surgical workflow

1. Patient preparation. Diagnostic imaging including MRI, CT, and angiography. Determination of surgical access and operative planning.
2. Surgery. Performed under general anesthesia. The endoscope is introduced through a small incision or natural openings (nose, oral cavity). Specialized instruments are used to perform the procedure.
3. Completion. Placement of drains if necessary. Suturing or minimal wound management.

Indications for endoscopic neurosurgery

• Hydrocephalus.
• Pituitary adenomas.
• Intervertebral disc herniations.
• Intracerebral cysts.
• Skull base tumors.
• Intracranial hematomas.
• Vestibular schwannomas (acoustic neuromas).

Contraindications

• Uncontrolled coagulation disorders.
• Large or complex tumors requiring an open surgical approach.
• Active infectious processes in the area of the planned surgical access.

Rehabilitation after endoscopic surgery

1. Short-term period. The patient may be discharged within 1–3 days after surgery.
2. Rehabilitation measures. Physiotherapy to restore function. Light physical exercises.
3. Medical follow-up. Regular visits to a neurosurgeon and follow-up imaging studies (MRI, CT).

Endoscopic neurosurgery in Belarus represents modern and effective methods for the treatment of diseases of the brain and spinal cord. High precision, minimal invasiveness, and rapid recovery make this approach a preferred option for many neurosurgical interventions. Proper patient selection and timely referral to a specialist significantly increase the chances of successful recovery.
