A craniotomy for tumor resection is a specialized brain surgery performed to remove a brain tumor by temporarily opening the skull to access the brain. Neurosurgeons carefully remove as much of the tumor as possible while protecting nearby healthy brain tissue, nerves, and blood vessels to preserve neurological function and improve patient outcomes.
What Is a Craniotomy for Tumor Resection?
A craniotomy for tumor resection is one of the most common surgical procedures used to treat brain tumors. During surgery, a neurosurgeon creates a carefully planned opening in the skull (craniotomy) to reach and remove the tumor from the brain.
The primary goals of tumor resection surgery are to:
- Remove as much tumor tissue as safely possible
- Relieve pressure on the brain
- Improve neurological symptoms
- Preserve normal brain function
- Obtain tissue for diagnosis and treatment planning
At Midwest Spine & Brain Institute, advanced brain tumor surgery is performed using microsurgical techniques, image-guided navigation, brain mapping technology, and minimally invasive approaches whenever appropriate.
Patients across Minnesota and Wisconsin receive comprehensive neurosurgical care tailored to their diagnosis, symptoms, and treatment goals.
Why Is Tumor Resection Surgery Performed?
Brain tumors may place pressure on surrounding brain tissue, interfere with neurological function, or continue growing over time.
Tumor resection surgery may help:
- Remove cancerous or noncancerous tumors
- Relieve headaches and pressure
- Reduce seizures
- Improve speech, vision, or movement problems
- Prevent further neurological damage
- Confirm tumor type through biopsy analysis
- Improve the effectiveness of additional treatments such as radiation or chemotherapy
In some cases, complete tumor removal may be possible. In others, surgeons remove as much tumor tissue as safely possible to avoid injury to critical brain structures.
Types of Brain Tumors Treated With Craniotomy
Craniotomy for tumor resection may be used to treat:
- Gliomas

Symptoms of Brain Tumors
Symptoms vary depending on the tumor’s size, location, and growth rate.
Common symptoms may include:
- Persistent headaches
- Seizures
- Vision changes
- Weakness or numbness
- Difficulty speaking
- Memory or cognitive problems
- Balance or coordination difficulties
- Personality changes
- Hearing loss
- Nausea and vomiting
- Fatigue
- Facial weakness
Some tumors may be discovered incidentally during imaging for unrelated concerns.
Causes and Risk Factors for Brain Tumors
The exact cause of many brain tumors remains unknown. However, certain factors may increase risk.
Possible risk factors include:
- Genetic syndromes
- Prior radiation exposure
- Family history of neurological tumors
- Age-related risk
- Metastatic cancer spreading to the brain
- Rare inherited conditions
Brain tumors may be benign (noncancerous) or malignant (cancerous).
How Brain Tumors Are Diagnosed
Accurate diagnosis and surgical planning require advanced neurological imaging and evaluation.
Diagnostic testing may include:
- Neurological examination
- MRI scans
- CT scans
- Functional MRI (fMRI)
- Brain mapping studies
- PET imaging
- Biopsy analysis
- Neurocognitive testing
Imaging helps determine tumor location, size, blood supply, and involvement of nearby brain structures.
How Is a Craniotomy for Tumor Resection Performed?
The surgical approach depends on the tumor’s location, size, and relationship to critical brain tissue.
General Steps of Tumor Resection Surgery
- The patient receives general anesthesia.
- The surgical area is carefully prepared.
- A section of the skull is temporarily removed.
- Advanced imaging and navigation guide tumor access.
- The neurosurgeon removes as much tumor tissue as safely possible.
- Brain function monitoring may be used during surgery.
- The skull bone is replaced and secured.
- The incision is closed carefully.
Modern surgical tools help improve precision while minimizing injury to surrounding healthy tissue.
Advanced Technologies Used During Brain Tumor Surgery
Modern tumor resection surgery may include:
- Microsurgical techniques
- Intraoperative MRI
- Neuronavigation systems
- Fluorescence-guided surgery
- Brain mapping
- Awake craniotomy procedures
- Endoscopic surgical assistance
- Neurophysiological monitoring
These technologies help surgeons maximize tumor removal while preserving important neurological function.
Awake Craniotomy for Brain Tumors
In selected patients, an awake craniotomy may be recommended when tumors are located near areas controlling speech, movement, or other critical brain functions.
During portions of the surgery:
- The patient may respond to simple questions or tasks
- Surgeons monitor brain activity in real time
- Critical neurological functions can be protected more effectively
Awake brain surgery is carefully planned and performed with specialized anesthesia and monitoring teams.
Benefits of Craniotomy for Tumor Resection
Potential benefits may include:
- Tumor removal or reduction
- Relief of pressure on the brain
- Improved neurological symptoms
- Reduced seizure activity
- Better long-term tumor control
- Improved effectiveness of additional cancer treatment
- Improved quality of life
- Accurate diagnosis through tissue analysis
Early treatment may help prevent progressive neurological damage.
Risks and Complications
As with any major brain surgery, tumor resection carries potential risks.
Possible complications may include:
- Bleeding
- Infection
- Seizures
- Stroke
- Swelling of the brain
- Memory or speech problems
- Weakness or numbness
- Cerebrospinal fluid leak
- Blood clots
- Neurological deficits
- Need for additional treatment
Your neurosurgical team will discuss risks, treatment goals, and expected outcomes before surgery.
Recovery After Brain Tumor Surgery
Recovery varies depending on the tumor type, location, and extent of surgery.
Recovery may include:
- Intensive neurological monitoring
- Hospital observation
- Pain management
- Physical therapy
- Occupational therapy
- Speech therapy
- Follow-up MRI imaging
- Oncology consultation if needed
- Gradual return to normal activities
Some patients recover within several weeks, while others may require longer rehabilitation and ongoing cancer treatment.
Can All Brain Tumors Be Completely Removed?
Not always. Some tumors are located near critical brain structures that control movement, speech, vision, or breathing.
In these situations, the neurosurgeon may remove as much tumor tissue as safely possible while minimizing the risk of neurological injury.
Additional treatments such as:
- Radiation therapy
- Stereotactic radiosurgery
- Chemotherapy
- Targeted therapy
may be recommended after surgery.
When to See a Brain Tumor Specialist
You should seek neurological evaluation if you experience:
- Persistent headaches
- Seizures
- Vision changes
- Balance problems
- Progressive weakness
- Speech difficulties
- Memory or personality changes
- Known brain mass or abnormal imaging findings
Early diagnosis and treatment may improve outcomes and preserve neurological function.
