Brain Tumor Surgery: A Comprehensive Overview

Brain tumor surgery is a critical procedure aimed at removing or reducing brain tumors that impact neurological function. It is often the primary treatment for tumors that are operable and involves a complex and delicate approach. The goal of surgery is to remove as much of the tumor as possible while preserving healthy brain tissue to minimize potential risks or long-term disabilities.

Types of Brain Tumor Surgery

There are several surgical methods used for brain tumor removal, including craniotomy, stereotactic surgery, and endoscopic surgery. A craniotomy involves removing a portion of the skull to access the tumor, and it is the most common approach for larger tumors. Stereotactic surgery is a minimally invasive technique that uses imaging technology to guide the surgeon to the exact location of the tumor. Endoscopic surgery uses a small camera and instruments to remove tumors through smaller incisions, reducing recovery time and risks.

Pre-Surgery Assessment and Preparation

Before undergoing brain tumor surgery, patients must undergo a series of diagnostic tests, including brain imaging such as MRI or CT scans. These tests help determine the size, location, and type of tumor, which are crucial for planning the surgical approach. Patients may also need to undergo neurological exams to assess their cognitive and motor functions. Depending on the tumor's location and type, patients may be advised on specific pre-operative measures to minimize risks during surgery.
