Introduction

Awake craniotomy is a surgical technique for removing brain tumors while the patient remains conscious, allowing surgeons to continuously monitor neurological function. This minimizes the risk of damage to critical brain areas like those controlling speech and movement. It's especially useful for tumors located near these eloquent regions. This review highlights its role in enhancing patient safety and maximizing tumor removal, ultimately improving patient outcomes and quality of life after surgery [1].

Intraoperative fluorescence guidance significantly enhances the precision of brain tumor resection. This technique uses special dyes that make tumor cells glow under specific light, helping surgeons distinguish between cancerous and healthy tissue more clearly. What this means for patients is a more complete tumor removal, which is crucial for treatment effectiveness, while also protecting vital brain structures [2].

Advances in intraoperative neurophysiological monitoring have transformed brain tumor surgery by providing real-time feedback on brain function during operations. This constant feedback allows neurosurgeons to identify and preserve critical neural pathways, reducing the risk of postoperative neurological deficits. Here's the thing: it makes complex resections safer, particularly when tumors are close to functionally important areas [3].

Artificial Intelligence (AI) is making its mark in brain tumor surgery, promising to revolutionize various aspects of the surgical process. It helps with preoperative planning by analyzing imaging data, predicting surgical outcomes, and even assisting with intraoperative decision-making. The real benefit is its potential to improve diagnostic accuracy, personalize treatment strategies, and ultimately lead to better patient care [4].

Virtual and Augmented Reality (AR) are becoming powerful tools in brain tumor surgery. Virtual Reality (VR) helps surgeons practice complex procedures and plan precise surgical approaches before even stepping into the operating room. Augmented reality overlays vital patient data and anatomical structures onto the surgical field in real-time. This combination boosts surgical accuracy, reduces operating time, and ultimately enhances patient safety and outcomes [5].

Fluorescence-guided surgery is a key innovation for patients with high-grade gliomas. By using agents that accumulate in tumor cells and fluoresce under specific light, surgeons can better differentiate between cancerous and healthy brain tissue. This improved visualization during surgery helps achieve a more aggressive, yet safe, removal of the tumor, which is critical for extending survival and improving the quality of life for these patients [6].

New surgical techniques for brain tumor resection are constantly evolving, leading to less invasive approaches and improved functional outcomes. These advancements include enhanced visualization systems, more precise dissection tools, and real-time feedback technologies. What this really means is that surgeons can remove tumors more effectively while minimizing damage to healthy brain tissue, leading to faster recovery and better quality of life for patients [7].

Robotic surgery is carving out a significant role in neuro-oncology. These systems offer unparalleled precision and stability, allowing surgeons to perform delicate maneuvers in hard-to-reach areas of the brain. They can assist with complex resections, biopsies, and the placement of therapeutic devices. Let's break it down: robotics enhances the surgeon's capabilities, leading to potentially safer and more effective interventions for brain tumor patients [8].

Intraoperative imaging modalities have become indispensable in modern brain tumor surgery. Techniques like intraoperative Magnetic Resonance Imaging (MRI), ultrasound, and Computed Tomography (CT) provide real-time anatomical and functional information during the procedure. This immediate feedback helps surgeons confirm the extent of tumor removal and ensure the preservation of critical structures. It's a game-changer for maximizing resection while minimizing complications, improving surgical safety and efficacy [9].

Navigation systems and robotics are redefining precision in brain tumor surgery. Image-guided navigation provides surgeons with a 'GPS' for the brain, displaying the exact location of instruments relative to the patient's anatomy. When combined with robotic assistance, it allows for highly accurate trajectory planning and instrument manipulation. This integration makes complex surgeries more precise, minimizes tissue damage, and ultimately improves patient outcomes for challenging tumor resections [10].
