Endoscopic and exoscopic surgery for brain tumors.

Area of Science:

• Neurosurgery
• Surgical Technology
• Oncology

Background:

• Traditional brain tumor surgery relies on microscopes, posing challenges in visualizing delicate nerves and blood vessels.
• The advent of endoscopes and exoscopes in neurosurgery offers advanced visualization and access for tumor removal.
• Protecting critical neurovascular structures is paramount during surgical interventions for brain tumors.

Purpose of the Study:

• To review the current applications of endoscopes in brain tumor surgery.
• To discuss the emerging role and benefits of exoscopes in neurosurgical oncology.
• To explore the future potential of advanced visualization technologies in neurosurgery.

Main Methods:

• Review of literature on endoscopic and exoscopic techniques in brain tumor surgery.
• Analysis of the advantages of endoscopes over microscopes for neurosurgical procedures.
• Examination of exoscopes' impact on surgeon ergonomics and surgical outcomes.

Main Results:

• Endoscopes provide enhanced visualization and access, particularly in endoscopic endonasal surgery for pituitary tumors and skull base tumors.
• Endoscopic techniques are beneficial for managing hydrocephalus concurrently with brain tumor biopsies.
• Exoscopy offers a 3D, monitor-based approach that reduces surgeon fatigue and improves positioning during complex surgeries.

Conclusions:

• Endoscopes and exoscopes represent significant advancements in brain tumor surgery, improving visualization and enabling less invasive approaches.
• These technologies enhance the safety and efficacy of resecting various brain tumors, including pituitary and skull base.
• Future neurosurgery is expected to integrate robotic systems for even greater precision and safety in tumor removal.
