Objective:

To review the current catalogue of minimally invasive endoscopic surgical techniques for treating adult brain and skull base tumors, emphasizing their significance in improving surgical outcomes.

Key Findings:

• Minimally invasive approaches allow for 360-degree access to critical areas.
• Endoscopic techniques have evolved significantly over the last two decades, reflecting advancements in technology.
• Direct endoscopic approaches for pituitary tumors show high rates of hormonal remission and low complication rates.

Interpretation:

The advancements in minimally invasive neurosurgery enhance surgical outcomes and reduce recovery times for patients with cranial tumors, significantly impacting their quality of life.

Limitations:

• Challenges in visualization and irrigation during procedures in a CSF medium, particularly when bleeding occurs.
• Limitations in performing two-handed micro dissection in certain endoscopic techniques.

Conclusion:

Minimally invasive endoscopic techniques represent a significant advancement in neurosurgery, improving access and outcomes for cranial tumor surgeries.
