Craniotomy

What this procedure is

A craniotomy is a surgical procedure used to reach the brain. During the surgery, a surgeon carefully removes a small section of the skull, which is known as a bone flap. This creates an opening that allows the medical team to see and treat the specific area of the brain that needs care.

In most cases, the piece of bone is put back into its original position at the end of the surgery. It is typically secured with small metal plates or wires so it can heal properly. Your clinician may use advanced imaging and specialized tools to ensure the procedure is as precise as possible.

What it treats or fixes

This procedure is used to manage many different conditions that affect the brain or the space around it. Your healthcare team may recommend a craniotomy for several reasons, including:

• Removing or reducing the size of brain tumors.
• Repairing an aneurysm, which is a bulge or weak spot in a blood vessel.
• Removing blood clots, also called hematomas, to stop bleeding or reduce pressure.
• Draining fluid or treating infections, such as an abscess (a pocket of pus).
• Relieving pressure inside the skull after a head injury or stroke.

How common it is & where it's done

A craniotomy is a standard and common procedure in the field of neurosurgery. It is performed in a hospital setting, specifically in a specialized operating room. The surgery is led by a neurosurgeon, which is a doctor who specializes in operations on the brain, spine, and nervous system.

Because this is a significant procedure, it involves a large team of experts, including anesthesiologists and specialized nurses. After the surgery, patients usually stay in the hospital for several days. This often begins in an intensive care unit (ICU) or a dedicated recovery area where the medical staff can monitor your health and recovery closely.

Recovery: What to Expect

After your craniotomy—a surgery where a small piece of the skull is temporarily removed to access the brain—you will likely spend a few days in the hospital. Your care team will monitor you closely in the Intensive Care Unit (ICU) or a specialized recovery room. It is normal to feel tired or have a headache as you begin to heal.

Once you go home, your clinician may suggest a gradual return to your daily routine. You should avoid heavy lifting or intense exercise until your doctor says it is safe. It is important to keep your incision (the surgical cut) clean and dry. You should contact your care team if you notice any of the following:

• A fever or chills.
• Redness, swelling, or fluid leaking from the incision.
• A headache that gets worse even with medicine.
• New weakness in your arms or legs or a new seizure.

Risks & Possible Complications

Every surgery carries some risks, such as infection, bleeding, or reactions to anesthesia (the medicine that puts you to sleep). For a craniotomy, specific risks may include brain swelling, also called edema, or the development of blood clots. Your medical team uses specialized monitoring and medications to help lower these risks.

Some patients may experience seizures or changes in brain function, such as temporary issues with speech, vision, or balance. While these complications can be concerning, many are manageable with the help of your healthcare providers. Your clinician may prescribe certain medicines, like anti-seizure drugs, to help protect you during the early stages of recovery.

Outcomes & Long-Term Results

The long-term results of a craniotomy depend mostly on the reason for the surgery, such as removing a tumor or treating an aneurysm (a bulge in a blood vessel). Many people are able to return to their usual activities, though the timeline varies for everyone. Your clinician may schedule follow-up imaging, like an MRI or CT scan, to check on your progress.

To help with the best possible outcome, your care team might recommend rehabilitation. This could include:

• Physical therapy to help with strength and walking.
• Occupational therapy to help with daily tasks like dressing or cooking.
• Speech therapy to help with communication or swallowing.

Emotional Support & Reassurance

Recovering from brain surgery is a major event, and it is normal to feel a range of emotions. You may feel more tired than usual or experience "brain fog," where it is hard to focus. These feelings often improve as your body heals. Be patient with yourself and celebrate small milestones, like taking a short walk or having a clear conversation.

If you feel anxious, sad, or overwhelmed, remember that you are not alone. Many hospitals offer support groups for patients and families. Talking to your clinician about your mood is just as important as talking about your physical symptoms. With time and the right support, most patients find a "new normal" and continue to lead fulfilling lives.

Why doctors recommend it

A craniotomy is a surgical procedure where a surgeon carefully removes a piece of the skull to reach the brain. Your clinician may recommend this surgery if they need to treat a condition that cannot be managed with medicine alone. It is a common way for specialists to see and work on the brain directly.

There are several reasons why this procedure might be necessary, including:

• Brain tumors: To remove or reduce the size of abnormal growths.
• Blood vessels: To repair an aneurysm (a weak, bulging spot in a blood vessel) or a tangle of blood vessels.
• Infections: To drain an abscess, which is a pocket of infection.
• Injury: To repair a skull fracture or remove a blood clot (hematoma) after a head injury.

Urgent vs planned treatment

The timing of a craniotomy depends on the specific health concern. In many cases, the surgery is planned in advance. This is often the case for slow-growing tumors or other stable conditions. A planned surgery gives your medical team time to perform detailed imaging tests and prepare you for the procedure.

In other situations, the surgery may be performed urgently. This usually happens if there is a sudden medical emergency, such as a stroke or a severe head injury. If there is bleeding or rapid swelling that puts pressure on the brain, your clinician may decide that immediate surgery is the best way to protect brain function.

Goals of treatment

The primary goal of a craniotomy is to allow the surgical team to address a specific problem inside the head. What success looks like depends on the reason for the surgery. For example, the goal might be to remove as much of a tumor as possible while keeping the surrounding brain tissue safe.

Other important goals include:

• Relieving pressure: Reducing the squeezing effect on the brain caused by swelling or fluid buildup.
• Stopping symptoms: Helping to reduce or stop seizures, headaches, or problems with movement and speech.
• Diagnosis: Taking a small sample of tissue, called a biopsy, to learn more about a growth so the team can plan future treatments.

Your healthcare team will talk with you about the specific goals for your procedure and what you can expect during your recovery process.

Who may benefit

A craniotomy is a surgical procedure where a surgeon temporarily removes a piece of the skull, called a bone flap, to reach the brain. This may be necessary for several reasons, such as removing a brain tumor (an abnormal growth of cells) or treating an aneurysm (a weak, bulging spot in a blood vessel). It can also help your care team treat brain infections or repair skull fractures after a serious injury.

Your clinician may also recommend this surgery to relieve pressure inside the head. This pressure can be caused by a blood clot, known as a hematoma, or by swelling after a stroke or head injury. In some cases, a craniotomy is used to help treat long-term conditions like epilepsy or movement disorders by allowing doctors to access specific areas of the brain.

When it may not be the right option

While a craniotomy can be a vital treatment, it is not the right choice for everyone. Your care team will carefully weigh the benefits against the risks. For example, if a patient has a very serious underlying illness or is not healthy enough to undergo general anesthesia (the medicine used to keep you asleep during surgery), the procedure may be considered too risky.

The location of the issue also matters. If a tumor or blood clot is in a part of the brain that is very difficult to reach without causing damage, your clinician may suggest other treatments. These might include specialized radiation, medication, or less invasive procedures. The goal is always to choose the path that offers the best chance of recovery with the fewest complications.

Questions to ask your care team

It is normal to have many questions before a brain procedure. Bringing a list to your appointment can help you feel more prepared. You might consider asking:

• Why is a craniotomy the best option for my specific condition?
• What are the main goals we hope to achieve with this surgery?
• What are the potential risks and how will the team manage them?
• How long will I likely need to stay in the hospital after the procedure?
• Are there any other treatments we should explore before deciding on surgery?
• What will my recovery look like once I return home?

In the procedure room

When you enter the procedure room, you will be met by a specialized team including a neurosurgeon (a doctor who operates on the brain and spine), an anesthesiologist, and several nurses. The room is filled with advanced equipment designed to keep you safe and provide the surgeon with a clear view of the treatment area.

You will be placed on a padded bed in a specific position that allows the surgical team the best access to the area being treated. To ensure your head stays perfectly still during the surgery, your clinician may use a specialized device to hold it in place. A small section of your hair near the surgical site may be trimmed or shaved to keep the area clean and reduce the risk of infection.

High-level steps

The procedure begins with the surgeon making an incision (a surgical cut) in the scalp. After the scalp is moved aside, the surgeon carefully removes a piece of the skull, which is known as a bone flap. This creates an opening that allows the surgeon to reach the brain to perform the necessary repair or treatment.

Once the main part of the surgery is complete, the bone flap is typically put back into its original position. It is secured using small metal plates and screws that stay in your body permanently to help the bone heal. Finally, the scalp incision is closed using stitches or staples and covered with a sterile bandage or dressing.

Anesthesia and pain control

Most craniotomies are performed while you are under general anesthesia, which means you will be in a deep sleep and will not feel any pain during the operation. Your anesthesiologist will stay with you the entire time to monitor your comfort and safety.

When you wake up, it is normal to feel some soreness, a dull headache, or numbness around the incision site. Your care team will provide pain-relief medications through an IV or by mouth to help manage any discomfort. They will work closely with you to make sure you are as comfortable as possible during your initial recovery.

Monitoring and safety steps

Safety is the top priority throughout the procedure. Your medical team will constantly monitor your vital signs, such as your heart rate, blood pressure, and oxygen levels. In many cases, they also use specialized monitoring equipment to track brain waves and nerve activity, which helps protect healthy brain tissue during the surgery.

Your clinician may also place a small, temporary tube called a drain under the scalp. This is done to prevent fluid or blood from building up near the surgical site, which helps reduce pressure and promotes healing. This drain is usually removed within a day or two after the surgery.

Immediately after the procedure

After the surgery, you will be moved to a recovery room or an Intensive Care Unit (ICU) where nurses can watch you closely. You may feel groggy or tired as the anesthesia wears off. The nursing staff will check on you frequently, often asking you to squeeze their hands, wiggle your toes, or answer simple questions to monitor your brain function.

You will likely have a large bandage wrapped around your head to protect the incision. It is also common to have several tubes or lines, such as an IV for fluids and a catheter to drain urine, which are typically removed as you become more mobile. Your team will encourage you to sit up or move as soon as it is safe to do so.

Typical procedure length

A craniotomy is a complex and delicate procedure that requires a great deal of precision. On average, the surgery itself takes between 3 and 5 hours. However, the total time may vary depending on the specific reason for the surgery and the complexity of the treatment.

Your surgical team will provide your family or loved ones with updates during the procedure. Keep in mind that the total time you spend in the operating area includes the time needed for the anesthesia team to prepare you before the surgery begins and the time needed to wake up safely afterward.

Common approaches (open vs minimally invasive)

Your healthcare team will plan the surgery based on the location of the brain issue and your overall health. The goal is always to treat the problem safely while protecting healthy brain tissue.

• Traditional (Open) Craniotomy: This is the standard approach. The surgeon makes an incision in the scalp and removes a section of bone, called a bone flap. This creates a window large enough for the surgeon to see and reach the affected area clearly.
• Keyhole (Minimally Invasive) Craniotomy: For certain conditions, surgeons may use a much smaller incision. This might be done behind the ear or near the eyebrow. This approach often uses a tiny camera (endoscope) to see inside. It may lead to less scarring and a faster recovery, but it is not an option for every patient.
• Stereotactic Craniotomy: In this approach, doctors use computers and 3D imaging scans (like MRI or CT) to guide their tools to the exact spot. This helps them make the opening as small as possible.

Partial vs total

The terms "partial" and "total" can refer to how much tissue is removed or how the skull bone is handled. Your surgeon will discuss which goal applies to your specific situation.

• Biopsy vs. Resection: Sometimes, the surgeon only removes a small sample of tissue (a biopsy) to test it in a lab. In other cases, the goal is to remove the entire tumor or blood clot (resection). If a tumor is near sensitive areas controlling speech or movement, the surgeon may only remove part of it to preserve your brain function.
• Bone Flap Replacement: In a standard craniotomy, the piece of skull bone is put back in place with small plates and screws at the end of the surgery. However, if the brain is very swollen, the surgeon may leave the bone off temporarily. This procedure is called a decompressive craniectomy. This gives the brain room to expand without being squeezed.

Revision or repeat procedures

While many craniotomies are one-time events, some patients may need a follow-up procedure. This depends on the underlying condition and how well you heal.

• Cranioplasty: If the bone flap was removed to allow for swelling (craniectomy), a second surgery is usually performed weeks or months later to put the bone—or a custom implant—back in place. This restores the shape and protection of the skull.
• Recurrence: If a tumor grows back over time, a repeat craniotomy may be considered to remove the new growth.
• Wound Healing: Rarely, a revision is needed to help the incision heal properly or to treat an infection.

Tests and imaging that may be done

Before your surgery, your healthcare team needs to check your overall health and plan the procedure carefully. You will likely have a physical exam and a meeting with the anesthesia team to discuss your medical history.

Common tests prior to a craniotomy include:

• Blood tests: These check your blood counts and how well your blood clots.
• Imaging scans: A CT scan or MRI is usually done to create detailed pictures of your brain. These images act as a map for the surgeon.
• Heart and lung checks: You may have a chest X-ray or an electrocardiogram (ECG/EKG) to make sure your heart and lungs are strong enough for surgery.

Medication adjustments

It is important to tell your healthcare provider about everything you take. This includes prescription medicines, over-the-counter drugs, vitamins, and herbal supplements.

Your care team will give you a specific plan for your medications. General guidelines often include:

• Blood thinners and NSAIDs: You may be asked to stop taking medicines that thin the blood, such as aspirin, ibuprofen, or prescription anticoagulants, several days before surgery to lower the risk of bleeding. Only stop these medicines if your clinician instructs you to do so.
• Diabetes medications: If you take insulin or pills for diabetes, ask your doctor how to adjust your dose on the day of surgery since you will not be eating.
• Morning medications: Your doctor may allow you to take certain essential medicines on the morning of surgery with a small sip of water.

Day-before and day-of instructions

Your hospital will give you a specific checklist to follow as your surgery date approaches. Following these steps helps keep you safe during the procedure.

The day before surgery:

• Fasting: You will usually be told not to eat or drink anything after midnight the night before your surgery.
• Hygiene: You may need to wash your hair with a special antiseptic shampoo to kill bacteria on your skin.
• Packing: Pack a bag with loose, comfortable clothes and any toiletries you might need for your hospital stay. Leave valuables, such as jewelry and large amounts of money, at home.

The day of surgery:

• Skin preparation: Do not wear makeup, hairpins, nail polish, or contact lenses.
• Shaving: Do not shave your head at home. If hair removal is necessary, the surgical team will usually do this in the operating room after you are asleep.
• Arrival: Arrive at the hospital at the scheduled time to allow for check-in and final preparations before the procedure begins.

General surgical risks

As with any major surgery, a craniotomy carries certain general risks. Your surgical team takes many steps to lower these risks before, during, and after the procedure. Common general risks associated with surgery include:

• Reactions to anesthesia: Some patients may have a reaction to the medication used to keep them asleep during surgery.
• Infection: This can occur at the incision site (where the cut was made) or deeper inside the skull.
• Bleeding: Excessive bleeding may happen during the surgery or afterward.
• Blood clots: Being immobile during and after surgery can increase the risk of clots forming in the legs (deep vein thrombosis) or traveling to the lungs (pulmonary embolism).

Your age and overall health can influence how likely these risks are. Your care team will monitor your heart rate, blood pressure, and oxygen levels closely to catch these issues early.

Procedure-specific complications

Because a craniotomy involves the brain, there are specific risks related to the nervous system. The type of complication often depends on the exact location of the surgery within the brain. Possible complications include:

• Seizures: The surgery can irritate the brain, leading to seizures. This is a known risk, and preventative medication is often used.
• Brain swelling: Swelling is a natural response to surgery, but excessive swelling can increase pressure inside the skull.
• Cerebrospinal fluid leak: The clear fluid that cushions the brain may leak through the incision or nose. This usually requires repair to prevent infection.
• Nerve damage: Depending on the area operated on, there may be temporary or permanent muscle weakness, paralysis, or vision problems.
• Cognitive changes: Some patients may experience difficulties with speech, memory, balance, or coordination.

How complications are treated

Your medical team is prepared to manage complications if they arise. Treatment plans are tailored to the specific issue:

• Medication: Doctors frequently prescribe steroids to reduce brain swelling and anticonvulsant drugs to prevent or control seizures. Antibiotics are used if an infection is suspected or confirmed.
• Additional procedures: If fluid builds up or leaks, a surgeon may place a temporary drain or a shunt to redirect the fluid. In some cases, a second surgery may be needed to stop bleeding or repair a leak.
• Rehabilitation: If the surgery affects your movement, speech, or strength, physical, occupational, and speech therapy are standard parts of recovery. These therapies help the brain adapt and regain function over time.

Most complications are treatable, especially when caught quickly. Your care team will provide detailed instructions on what warning signs to look for once you return home.

Pain control medicines

Managing your comfort is a top priority for your care team. After a craniotomy, your clinician may use a combination of different medicines to help you feel better. This often includes acetaminophen or other common pain relievers. In some cases, stronger medications may be used for a short time while you are in the hospital to manage more intense discomfort.

Your team may also prescribe steroids, such as dexamethasone. These help reduce swelling in the brain tissue, which can improve how you feel and help you recover more quickly. Additionally, many patients receive anti-seizure medications (anticonvulsants) as a precaution to prevent seizures during the healing process. Your clinician will tailor this plan based on your specific needs.

Antibiotics

To help prevent infection at the surgical site, your clinician will likely give you antibiotics. These are usually started through an IV (a small tube in your vein) just before the surgery begins. In many cases, you may continue to receive them for a short period after the procedure is finished.

It is very important to tell your care team about any known allergies you have, especially to medications like penicillin. Your clinician will choose the safest antibiotic for you based on your health history. They will also monitor you for any signs of a reaction or side effects during your stay.

Blood thinners and clot prevention

Because you will be resting more than usual after surgery, there is a risk of developing blood clots in the legs. To help prevent this, your clinician may use special compression boots that gently squeeze your legs to keep blood moving. They may also use medications known as blood thinners or anticoagulants to lower the risk of clots.

Using blood thinners requires a careful balance to ensure safety after brain surgery. Your care team will monitor you closely to prevent clots while making sure your surgical site heals properly. Be sure to mention all other medications or herbal supplements you take, as these can sometimes cause interactions or increase the risk of bleeding.

Emergency warning signs

While recovery takes time, certain symptoms require immediate attention. You or a caregiver should call 911 or go to the nearest emergency room if you experience sudden, severe changes in your condition.

• Seizures: Any shaking, convulsions, or loss of consciousness.
• Breathing trouble: Sudden shortness of breath or chest pain, which could signal a blood clot in the lung.
• Stroke-like symptoms: Sudden weakness or numbness (especially on one side of the body), trouble speaking or understanding speech, or sudden vision loss.
• Change in alertness: Being very difficult to wake up or becoming unresponsive.

Call your surgeon or clinic if…

Contact your healthcare provider right away if you notice signs of infection or other complications. Catching these issues early is important for your recovery.

• Fever or chills: A temperature higher than 101°F (38.3°C), or whatever limit your surgeon provided.
• Incision changes: Increased redness, swelling, separation of the wound edges, or pus draining from the site.
• Fluid leakage: Clear or bloody fluid dripping from your incision, nose, or ears. This may indicate a leak of cerebrospinal fluid (the fluid that cushions the brain).
• Unmanaged pain: A severe headache that does not get better with your prescribed pain medicine.
• New physical symptoms: Sudden trouble with balance, coordination, or strength.

Expected vs concerning symptoms

It is helpful to know what is a normal part of healing and what might be a sign of a problem. Most people feel tired and have some discomfort for several weeks.

Common and expected symptoms:

• Fatigue: You will likely feel very tired and need extra naps.
• Mild headache: A dull ache is common and should improve over time.
• Scalp sensations: You may feel numbness or itching around the incision as nerves heal.
• Bruising: Some swelling or bruising around the eyes or face is common, especially in the first few days.

Concerning symptoms (seek advice):

• Stiff neck: A very stiff, painful neck (especially with a fever) can be a sign of meningitis.
• Leg pain: Swelling, redness, or tenderness in the calf or leg, which could indicate a blood clot (deep vein thrombosis).
• Confusion: New or worsening confusion or memory problems.
• Vision changes: Double vision or blurry vision that does not go away.

Non-surgical treatments

In many cases, your clinician may first suggest treatments that do not involve surgery. These options often focus on managing symptoms or treating the underlying cause with medicine. For example, doctors may use steroids to help reduce swelling in the brain or specialized medications to prevent seizures. If the goal is to treat a growth, your care team might suggest radiation therapy, which uses targeted energy beams to treat a specific area without an incision.

Other non-surgical approaches include managing blood pressure or using specific fluids to help control the pressure inside the skull. These treatments are often used when a condition is stable or when the risks of surgery might outweigh the benefits at that time.

Watchful waiting

Watchful waiting, also known as active surveillance, is a common approach for conditions that are not causing symptoms. If a growth or a blood vessel issue is small and appears stable, your clinician may choose to monitor it closely rather than operating right away. This involves having regular imaging tests, such as MRI or CT scans, to check for any changes over time.

This approach allows you to avoid the recovery time of surgery as long as the condition remains unchanged. It is often used for slow-growing tumors or small aneurysms (a bulge in a blood vessel) that do not pose an immediate risk to your health.

When surgery becomes the best option

A craniotomy often becomes the best option when non-surgical treatments are no longer effective or if a condition becomes more serious. Your clinician may recommend surgery if imaging shows that a growth is getting larger or if you begin to experience new symptoms, such as increased headaches, weakness, or vision changes.

Surgery may also be necessary in urgent situations, such as:

• Relieving pressure: If fluid or blood builds up and creates dangerous pressure inside the skull.
• Preventing damage: If a tumor is pressing on a sensitive part of the brain that controls movement or speech.
• Stopping a leak: If a blood vessel needs to be repaired to prevent or stop bleeding.

The decision to move to surgery is usually based on protecting your brain function and preventing long-term complications that medicine alone cannot manage.

Hospital services that commonly perform this surgery

A craniotomy is a specialized procedure usually performed in hospitals with a dedicated neurosurgery department. These departments focus on the brain, spine, and nervous system. Because this surgery requires close monitoring, your clinician may recommend a facility that has a Neuro-Intensive Care Unit (Neuro-ICU). This is a specialized area of the hospital where the staff is trained specifically to care for patients recovering from brain surgery.

Depending on the reason for the surgery, you may also interact with other specialized departments. For example, some hospitals have dedicated centers for brain tumors, epilepsy, or trauma. These centers bring together different experts, such as neurologists (doctors who treat brain disorders) and neurosurgeons, to coordinate your care before and after the procedure.

Patient resources and support services

Recovering from a craniotomy often involves a team of professionals. Most hospitals provide access to social workers and case managers who help you plan for your care after you leave the hospital. They can assist with insurance questions, coordinate home health services, or help you find a rehabilitation center if you need extra time to recover before going home.

Support services also include rehabilitation specialists. Physical therapists help you with movement and strength, while occupational therapists help you practice daily tasks like dressing or eating. Many hospitals also offer support groups where you and your family can connect with others who have had similar procedures. These groups provide a space to share experiences and find emotional support during the recovery process.

Questions for choosing where to have surgery

Choosing where to have your surgery is an important step. You may want to ask your clinician or the hospital staff several questions to help you feel more comfortable with your choice. Here is a short checklist of questions to consider:

• How many craniotomies does this hospital perform each year? Facilities that perform these surgeries frequently often have more experience with the recovery process.
• Is there a dedicated Neuro-ICU? Having a specialized unit for brain surgery recovery can provide more focused care from nurses and doctors trained in neurology.
• What rehabilitation services are available? Ask if physical, occupational, and speech therapy are available on-site or if the hospital helps coordinate these services nearby.
• Who will be on my care team? It is helpful to know if you will have access to specialized nurses, social workers, and therapists throughout your stay.
• What support is available for my family? Ask about family education, support groups, and resources to help your loved ones understand your recovery needs.

Conditions commonly treated by this procedure

A craniotomy is a surgical procedure where a small piece of the skull is temporarily removed to allow a surgeon access to the brain. Your clinician may recommend this procedure to treat several different health issues affecting the head and brain.

• Brain tumors: This includes both non-cancerous (benign) and cancerous (malignant) growths that may need to be removed or sampled for testing.
• Blood vessel issues: Surgeons may use this approach to repair an aneurysm (a bulge in a blood vessel wall) or to treat abnormal tangles of blood vessels.
• Blood clots and bleeding: A craniotomy can help remove blood clots, known as hematomas, or stop bleeding caused by an injury or a stroke.
• Infections: If an abscess, which is a pocket of infection, develops in the brain, this procedure may be used to drain it.
• Brain pressure: In some cases, it is used to relieve pressure inside the skull caused by swelling or fluid buildup after a traumatic injury.

Related symptoms people search for

While many different health issues can cause these symptoms, they are often what lead people to seek a medical evaluation. If you experience these, your clinician may use imaging tests to determine if a procedure is necessary.

• Persistent headaches: Frequent or severe head pain that does not go away with usual treatments.
• Seizures: Sudden, uncontrolled electrical disturbances in the brain that can cause changes in behavior, movements, or consciousness.
• Neurological changes: This may include unexplained weakness, numbness, or tingling, often occurring on one side of the body.
• Vision or speech problems: Difficulty speaking clearly, trouble understanding words, or sudden changes in how you see.
• Cognitive issues: Feeling unusually confused, having memory problems, or experiencing significant changes in personality.

It is important to remember that these symptoms do not always mean you need surgery. Only a qualified healthcare professional can provide a diagnosis and determine the best course of care for your specific situation.

Evidence overview

Craniotomy is a well-established procedure in neurosurgery. It has been performed for many years to treat conditions such as brain tumors, aneurysms, and blood clots. Medical evidence supports the use of this surgery when a direct approach to the brain is necessary for treatment. Advances in medical technology, such as high-resolution imaging and surgical microscopes, help surgeons plan the procedure with high precision.

Research continues to refine how this surgery is performed. For example, some patients may be candidates for "keyhole" craniotomies. These are minimally invasive techniques that use smaller openings to reach the brain. Studies suggest that for eligible patients, these smaller approaches may lead to less scarring and faster recovery times compared to traditional open surgery.

Safety notes and individualized care

Because a craniotomy involves operating on the brain, it is considered major surgery. Your surgical team follows strict safety protocols to protect your health. This includes using general anesthesia and monitoring your heart rate, blood pressure, and oxygen levels throughout the operation. While the procedure is common, it does carry risks. Potential complications can include infection, bleeding, blood clots, or seizures.

Your specific risks depend on your age, general health, and the location of the problem within the brain. For example, if surgery is needed near areas that control speech or movement, the surgeon may use special mapping techniques. In some cases, an "awake craniotomy" is performed. This allows the team to ask you questions during the surgery to ensure important brain functions are preserved.

After the procedure, care is highly individualized. You will be monitored closely in the hospital for signs of brain swelling or changes in alertness. Your clinician will discuss what symptoms to watch for as you recover at home.
