Brain, Cranial & Nerve
Craniotomy for Brain Tumor
Surgical removal of a brain tumor with image guidance, operating microscope, and — when the tumor is near eloquent cortex — awake mapping.
What it is
A craniotomy is a planned opening in the skull to access a brain tumor. The bone removed is temporarily set aside and replaced at the end of the operation, secured with small titanium plates. There is no permanent skull defect.
Modern brain tumor surgery is not just about removing the tumor — it's about removing it without injuring the brain around it. Image-guided navigation tracks where we are in three dimensions. The operating microscope gives us submillimeter visualization. For tumors near speech, motor, or language areas, awake mapping lets us preserve function we can't see on imaging alone.
Why this procedure when surgery is needed
For a brain tumor that is causing or threatens to cause symptoms, that needs a tissue diagnosis, or that has been shown to benefit from maximal safe resection for its tumor type, surgery is the foundation of treatment. For many primary brain tumors, the extent of resection correlates directly with outcomes.
The phrase that matters is maximal safe resection — taking as much tumor as we can take without injuring the functional brain around it. For tumors near critical cortex, that boundary is defined by direct cortical and subcortical mapping during surgery.
What to expect
Surgery duration varies widely by tumor — typically 3–6 hours.
Hospital stay of 2–5 nights for most cases.
Some incisional discomfort and short-term swelling at the surgical site.
Most patients walk and eat within 24 hours of surgery.
Return to most activities in 6–8 weeks; full neurologic recovery may take longer.
Pathology results typically take 5–10 days; we meet to review and plan next steps together.
Risks and how we reduce them
The goal of brain tumor surgery is maximal safe resection — removing as much tumor as possible without injuring functional brain — but operating in the brain carries serious risks that we plan carefully to reduce, not eliminate.
Expected, temporary effects
Scalp and jaw soreness. Soreness along the incision, and sometimes discomfort with chewing from the muscle near the temple, in the first weeks.
Fatigue, headaches, and swelling. Short-term fatigue, headaches, and swelling around the surgical site are common in the early recovery and improve over weeks.
Serious risks
Seizure. Surgery near the brain can provoke seizures, and seizure medication is often used around the operation. After a craniotomy — and especially after any seizure — there are restrictions on driving and certain activities; the timeline is set by your surgeon and by state law.
New or worsened neurologic deficit. Depending on the tumor location, surgery can cause new weakness, numbness, or changes in speech, language, or vision. Navigation, the operating microscope, neuromonitoring, and awake mapping near critical areas are used to reduce this risk.
Stroke. Injury to a blood vessel during surgery can cause a stroke, with effects that depend on the area involved.
Bleeding at the surgical site. Bleeding into the tumor bed after surgery is uncommon but can require a return to the operating room.
Infection. Wound infection or, rarely, meningitis can occur and is minimized with sterile technique and antibiotics.
CSF leak. Leakage of spinal fluid through the incision can occur and sometimes needs additional treatment.
Blood clot (DVT/PE). Clots in the legs or lungs are a risk after cranial surgery and are reduced with early mobilization and preventive measures.
Your recovery, phase by phase
A general timeline for this procedure. Your surgeon’s own protocol takes precedence — use this to know what to expect and what questions to ask at each visit.
Before surgery
- Bring a complete list of your medications and supplements to the pre-anesthesia visit. Blood thinners, NSAIDs, GLP-1 medications, and some supplements are held on a schedule the team sets for you.
- You may be started on a steroid to control swelling around the tumor, and sometimes an anti-seizure medication, before surgery — take these exactly as prescribed.
- Preoperative imaging — a thin-cut MRI or CT — is obtained so the navigation system can guide the operation. You stop eating after midnight; the anesthesia team sets your clear-liquid cutoff.
- Arrange help at home and a ride to and from the hospital, and line up someone who can stay with you in the early recovery.
The day of surgery
- Arrive early to check in, change, have an IV placed, and meet Dr. Tuchek, the anesthesiologist, and the OR team.
- The operation is done under general anesthesia for most tumors; for a tumor near speech, language, or motor areas, part of the surgery may be done awake so those functions can be mapped and protected.
- Usually only a small area of hair is shaved. Image-guided navigation and the operating microscope are used throughout, and the bone removed to reach the tumor is replaced and secured with small titanium plates at the end.
- Surgery duration varies widely by tumor. Your family waits nearby, and Dr. Tuchek speaks with them once the operation is finished.
In the hospital
- You typically start recovery in an ICU or close-monitoring unit for frequent neurologic checks, then move to a regular floor. Most stays are about two to five nights.
- Most patients are up walking and eating within about a day; early walking lowers the risk of blood clots.
- Steroids are continued and then tapered on a schedule your team sets, and any anti-seizure medication is managed by the team — follow the schedule exactly and do not stop either one on your own.
- Before you go home, the care team teaches you and your caregiver what to watch for.
The first two weeks
- Soreness along the incision, some scalp or temple discomfort, headaches, and short-term swelling near the surgical site are common and improve over the weeks.
- Fatigue is one of the most common effects of brain surgery — plan for rest and pace your activity as your energy allows.
- Keep the incision clean and dry and follow your discharge instructions; the team tells you when staples or sutures come out.
- Driving is on hold. After a craniotomy — and especially after any seizure — driving is restricted by your surgeon’s guidance and by state law; your team tells you when it is safe and legal to resume.
- Your caregiver should call 911 for a seizure, a sudden severe headache, worsening drowsiness or confusion, or new weakness, numbness, or trouble speaking, and call the office for fever or an incision that is draining or spreading redness. The clinic phone line is not an emergency line.
Weeks 2 to 6
- Pathology results typically take about five to ten days; you meet with the team to review the diagnosis and plan any next steps, which may include radiation or medical oncology.
- Energy and stamina rebuild gradually. Many patients return to most activities around six to eight weeks, though the timeline depends on the tumor’s location and your recovery.
- A follow-up visit checks the incision and your neurologic recovery; your surgeon guides when to taper any remaining steroid or seizure medication.
Long-term recovery
- Recovery is individual — full neurologic recovery can take longer than the incision takes to heal, and follow-up imaging is used to monitor the area over time.
- Ongoing care is usually shared with medical and radiation oncology; your team coordinates the plan that fits your tumor’s pathology.
Milestone checkpoints
| Window | Milestone | What to expect |
|---|---|---|
| Post-op days 1-3 | Close monitoring, then the floor | Most patients start in an ICU or close-monitoring unit for frequent neurologic checks, then move to a regular hospital floor. The stay is often about two to five nights, depending on the tumor and your recovery. |
| Post-op days 1-3 | Up and moving early | Most patients are walking and eating within about a day of surgery. Early walking helps guard against blood clots and pneumonia. |
| Post-op days 1-3 | Incision and hair | Usually only a small area of hair is shaved. Expect soreness along the incision and sometimes discomfort near the temple with chewing. Keep the incision clean and dry and follow your discharge instructions on when staples or sutures come out. |
| Surgeon-directed | Steroid taper | A steroid is often used to control swelling around the brain and is tapered on a specific schedule your team sets. Do not stop it abruptly or skip doses — follow the taper exactly as written. |
| Surgeon-directed | Seizure medication | Anti-seizure medication is often used around the time of surgery. Whether and how long to continue it is decided by your surgeon — take it exactly as prescribed and do not stop on your own. |
| Checkpoint | Driving | Driving is on hold until you are off sedating medication and your surgeon clears you. After a craniotomy — and especially after any seizure — driving is restricted by state law; your team tells you when it is safe and legal to resume. |
| Checkpoint | Return to work | Many patients return to most activities around six to eight weeks, but the timeline varies widely with the tumor's location, the pathology, and your recovery. Your surgeon clears the timeline that fits you. |
| Week 2 | Pathology results and follow-up | Pathology results typically take about five to ten days. You meet with the team to review the diagnosis and plan next steps together, and the incision is checked at your follow-up visit. |
| Week 6 | Fatigue eases gradually | Fatigue is one of the most common and longest-lasting effects of brain surgery. Energy returns gradually and full neurologic recovery may take longer than the incision takes to heal — pace yourself and rest as needed. |
| Any time | When to call | Call the office for fever, or an incision that is draining, reddening, or spreading. A seizure, a sudden severe headache, worsening drowsiness or confusion, or new weakness, numbness, or trouble speaking is an emergency — call 911. The clinic phone line is not an emergency line. |
