Brain Tumor Surgery

During a craniotomy for a brain tumor, the surgeon temporarily removes a small section of skull to reach the tumor, removes as much of it as can be safely taken out, then replaces the bone and closes the incision. Most procedures use general anesthesia and take about three to five hours. Tools like neuronavigation and, when needed, brain mapping help protect areas that control speech, movement, and other functions.

Recovery is gradual. Most patients stay in the hospital about two to five days, then recover at home. Headaches, fatigue, and low energy are common in the first weeks. Many people find their energy and daily function return over roughly six to eight weeks, though larger or more complex surgeries can take longer. The surgeon sets activity limits and clears patients to resume normal activity over time.

Brain surgery carries real risks, including bleeding, infection, seizures, swelling, and new or worsened problems with movement, speech, or thinking. How risky any specific operation is depends heavily on the tumor's size and location. Surgeons use neuronavigation, intraoperative monitoring, awake mapping near critical areas, and image guidance to reduce these risks. Risks and benefits are discussed in detail before any decision, and outcomes cannot be guaranteed.

Most patients are discharged about two to five days after a craniotomy for a brain tumor, often after spending the first night in an intensive care or close-observation unit. The exact timing depends on how the surgery went, how quickly someone recovers, and whether any complications need further care. Discharge usually comes with instructions on incision care, activity limits, medications, and a follow-up visit within one to two weeks.

Maximal safe resection is the guiding goal of most brain tumor surgery. It means removing as much of the tumor as possible without harming the parts of the brain that control speech, movement, vision, and memory. For many tumors, removing more tumor at the first operation is linked to better outcomes, so surgeons balance how much they remove against protecting essential function, guided by the tumor's location.

Usually not entirely. In most modern brain tumor surgery, only the hair near the incision is trimmed rather than the whole head. The exact amount depends on where the tumor is and the surgeon's approach. The surgical team prepares and sterilizes the area before the operation, and the incision is closed with staples or sutures that are typically removed at a follow-up visit one to two weeks later.

An awake craniotomy is a brain tumor operation in which the patient is awake for part of the procedure. It is used when a tumor sits near regions that control speech or movement. While the patient performs simple tasks like talking or moving a hand, the surgeon maps which areas are essential and avoids them. This real-time feedback can allow more tumor to be removed while lowering the chance of a lasting deficit.

After surgery, removed tissue is examined by a neuropathologist to confirm the diagnosis and grade, and for many tumors it also undergoes molecular profiling of the tumor's DNA. Initial pathology often takes several days, while full molecular results can take up to a couple of weeks. These findings guide what comes next, which may include radiation, chemotherapy, observation, or a clinical trial.

It depends on the tumor's location and the goal. When a tumor is accessible and removing it would help, a craniotomy both treats the tumor and provides tissue for diagnosis. When a tumor is deep or in a high-risk area, a needle biopsy may be used to get a diagnosis with less risk, followed by radiation or other treatment. The choice is made case by case based on imaging and overall health.
