Craniotomy

What is a craniotomy?

A craniotomy is the surgical removal of part of the bone from the skull to expose the encephalon. Specialized tools are used to remove the department of bone called the bone flap. The bone flap is temporarily removed, and so replaced later on the brain surgery has been done.

Some craniotomy procedures may use the guidance of computers and imaging (magnetic resonance imaging [MRI] or computerized tomography [CT] scans) to achieve the precise location within the brain that is to exist treated. This technique requires the employ of a frame placed onto the skull or a frameless system using superficially placed markers or landmarks on the scalp. When either of these imaging procedures is used forth with the craniotomy procedure, information technology is called stereotactic craniotomy.

Scans made of the brain, in conjunction with these computers and localizing frames, provide a iii-dimensional image, for example, of a tumor within the brain. It is useful in making the stardom between tumor tissue and good for you tissue and reaching the precise location of the abnormal tissue.

Other uses include stereotactic biopsy of the brain (a needle is guided into an abnormal expanse so that a piece of tissue may be removed for test under a microscope), stereotactic aspiration (removal of fluid from abscesses, hematomas, or cysts), and stereotactic radiosurgery (such as gamma knife radiosurgery).

An endoscopic craniotomy is another type of craniotomy that involves the insertion of a lighted scope with a photographic camera into the brain through a pocket-size incision in the skull.

Aneurysm clipping is another surgical procedure which may require a craniotomy. A cognitive aneurysm (as well chosen an intracranial aneurysm or brain aneurysm) is a bulging weakened area in the wall of an avenue in the encephalon, resulting in an aberrant widening or ballooning. Because of the weakened area in the artery wall, at that place is a risk for rupture (bursting) of the aneurysm. Placement of a metallic prune across the "neck" of the aneurysm isolates the aneurysm from the rest of the circulatory system by blocking blood menses, thereby preventing rupture.

Craniectomy is a similar procedure during which a portion of the skull is permanently removed or replaced afterward during a second surgery after the swelling has gone down. .

Other related procedures that may be used to diagnose brain disorders include cognitive arteriogram , computed tomography (CT) browse of the brain , electroencephalogram (EEG) , magnetic resonance imaging (MRI) of the brain , positron emission tomography (PET) browse , and X-rays of the skull . Please encounter these procedures for additional data.

Our Approach to Craniotomy

Johns Hopkins neurosurgeons are highly skilled and experienced in all types of craniotomy including newer, less invasive options for encephalon tumor surgery, aneurysm surgery and other procedures. In addition, a specialized dispensary offers patients safety repair of skull deformities after brain surgery.

Types of Craniotomy

Extended Bifrontal Craniotomy

The extended bifrontal craniotomy is a traditional skull base of operations approach used to target difficult tumors toward the front of the encephalon. It is based on the concept that information technology is safer to remove actress bone than to unnecessarily dispense the brain.

The extended bifrontal craniotomy involves making an incision in the scalp behind the hairline and removing the bone that forms the contour of the orbits and the forehead. This bone is replaced at the end of surgery. Temporarily removing this bone allows surgeons to work in the space between and correct behind the eyes without having to unnecessarily dispense the brain.

The extended bifrontal craniotomy is typically used for those tumors that are not a candidate for removal by minimally invasive approaches because of either the anatomy of the tumor, the possible pathology of the tumor or the goals of surgery.

Types of tumors treated with the extended bifrontal craniotomy include meningiomas , esthesioneuroblastomas and malignant skull base tumors .

Minimally Invasive Supra-Orbital "Eyebrow" Craniotomy

Supra-orbital craniotomy (oftentimes called "eyebrow" craniotomy) is a process used to remove brain tumors. In this process, neurosurgeons brand a small incision inside the eyebrow to access tumors in the front of the brain or around the pituitary gland, which is deeper in the brain behind the nose and eyes. This approach is used instead of endonasal endoscopic surgery when a tumor is very big or close to the optic fretfulness or vital arteries.

Because it is a minimally invasive procedure, supra-orbital "eyebrow" craniotomy may offer

Less pain than open craniotomy
Faster recovery than open up craniotomy
Minimal scarring

The supra-orbital craniotomy may exist part of the treatment for Rathke'southward fissure cysts, skull base tumors and some pituitary tumors.

Retro-Sigmoid "Keyhole" Craniotomy

Retro-sigmoid craniotomy (often called "keyhole" craniotomy) is a minimally-invasive surgical procedure performed to remove brain tumors. This procedure allows for the removal of skull base tumors through a small incision behind the ear, providing access to the cerebellum and brainstem. Neurosurgeons may employ this approach to reach certain tumors, such every bit meningiomas, audio-visual neuromas (vestibular schwannomas), skull base tumors and metastatic encephalon tumors.

Benefits of "keyhole" craniotomy includes less pain after the procedure than after an open up craniotomy, less scarring and a more than rapid recovery.

Orbitozygomatic Craniotomy

The orbitozygomatic craniotomy is a traditional skull base of operations approach used to target hard tumors and aneurysms. Information technology is based on the concept that it is safer to remove actress bone than to unnecessarily dispense the brain.

Typically used for those lesions that are too complex for removal by more minimally invasive approaches, orbitozygomatic craniotomy involves making an incision in the scalp behind the hairline and removing the bone that forms the profile of the orbit and cheek. This os is replaced at the cease of surgery. Temporarily removing this bone allows surgeons to reach deeper and difficult parts of the brain while minimizing astringent damage to the brain.

Brain tumors that may exist treated with orbitozygomatic craniotomy include craniopharyngiomas, pituitary tumors and meningiomas.

Translabyrinthine Craniotomy

A translabyrinthine craniotomy is a procedure that involves making an incision in the scalp backside the ear, and then removing the mastoid bone and some of the inner ear bone (specifically, the semicircular canals which contain receptors for balance). The surgeon so finds and removes the tumor, or as much of the tumor every bit possible without risk of astringent damage to the brain.

When at that place is no useful hearing or hearing is to be sacrificed, the translabyrinthine approach is oftentimes considered for removal of acoustic neuromas. During the translabyrinthine craniotomy, the semicircular canals of the ear are removed in order to access the tumor. Complete hearing loss occurs equally a result of the removal of the semicircular canals.

Although hearing is lost with the translabyrinthine craniotomy, the hazard of facial nerve injury may be reduced.

Reasons for the process

A craniotomy may exist done for a variety of reasons, including, just not limited to, the following:

Diagnosing, removing, or treating encephalon tumors
Clipping or repairing of an aneurysm
Removing blood or blood clots from a leaking blood vessel
Removing an arteriovenous malformation (AVM) or addressing an arteriovenous fistula (AVF)
Draining a brain abscess, which is an infected pus-filled pocket
Repairing skull fractures
Repairing a tear in the membrane lining the encephalon (dura mater)
Relieving pressure level within the brain (intracranial pressure) by removing damaged or bloated areas of the brain that may be caused by traumatic injury or stroke
Treating epilepsy
Implanting stimulator devices to treat movement disorders such as Parkinson's disease or dystonia (a type of movement disorder)

There may be other reasons for your dr. to recommend a craniotomy.

Risks of the procedure

As with whatever surgical process, complications may occur. Encephalon surgery risk is tied to the specific location in the brain that the operation will affect. For case, if the surface area of the encephalon that controls speech is operated on, and so speech may exist affected. Some more general complications include, simply are not limited to, the following:

Infection
Bleeding
Claret clots
Pneumonia (infection of the lungs)
Unstable blood pressure
Seizures
Muscle weakness
Brain swelling
Leakage of cerebrospinal fluid (the fluid that surrounds and cushions the brain)
Risks associated with the utilise of full general anesthesia

The following complications are rare and generally chronicle to specific locations within the brain, so they may or may not be valid risks for certain individuals:

Memory issues
Speech communication difficulty
Paralysis
Abnormal balance or coordination
Coma

In that location may be other risks depending on your specific medical condition. Be certain to discuss any concerns with your physician prior to the procedure.

Earlier the procedure

Your dr. will explain the procedure to you and you lot tin can ask questions.
Y'all will exist asked to sign a consent form that gives permission to exercise the surgery. Read the form carefully and ask questions if something is not clear.
In addition to a complete medical history, your doctor volition do a physical test to ensure y'all are in good health earlier you lot undergo the surgery. You may also demand blood tests and other diagnostic tests.
You will receive a preoperative neurological examination that will be used to compare with postoperative exams.
You volition be asked to fast before the procedure, mostly after midnight.
If you are significant or remember yous may be, tell your healthcare provider.
Tell your dr. if you are sensitive to or are allergic to whatsoever medicines, latex, record and anesthetic agents (local or general).
Tell your doctor of all medicines (prescribed and over-the-counter) and herbal supplements that y'all are taking.
Tell your physician if yous have a history of bleeding disorders or if you lot are taking any anticoagulant (blood-thinning) medicines, aspirin, or other medicines that affect blood clotting. It may exist necessary for y'all to stop these medicines earlier the procedure.
If you fume, you lot should stop smoking equally soon as possible earlier the procedure to amend your chances for a successful recovery from surgery and to amend your overall health condition.
You may be asked to wash your hair with a special antiseptic shampoo the dark earlier the surgery.
You may receive a sedative before the procedure to aid you relax.
The areas around the surgical site will be shaved.
Based on your medical condition, your physician may request other specific preparation.

Illustration of an example of a craniotomy procedure

During the procedure

A craniotomy mostly requires a infirmary stay of 3 to 7 days. You may besides get to a rehabilitation unit of measurement for several days later on your hospital stay. Procedures may vary depending on your condition and your doc'due south practices.

Generally, a craniotomy follows this process:

You will be asked to remove any clothing, jewelry, or other objects that may interfere with the procedure.
You volition exist given a gown to clothing.
An intravenous (Iv) line will exist inserted in your arm or hand.
A urinary catheter will be inserted to drain your urine.
Y'all will be positioned on the operating table in a manner that provides the best access to the side of the encephalon to be operated on.
The anesthesiologist will continuously monitor your heart charge per unit, claret pressure, breathing, and claret oxygen level during the surgery.
Your head volition be shaved and the skin over the surgical site will be cleansed with an antiseptic solution.
In that location are various types of incisions that may be used, depending on the affected area of the brain. An incision may be fabricated from behind the hairline in front of your ear and the nape of your neck, or in another location depending on the location of the trouble. If an endoscope is used, the incisions may be smaller.
Your head will be held in place past a device which volition be removed at the end of the surgery.
The scalp volition be pulled up and clipped to control haemorrhage while providing access to the encephalon.
A medical drill may exist used to make burr holes in the skull. A special saw may be used to advisedly cut the bone.
The bone flap will be removed and saved.
The dura mater (the thick outer covering of the brain straight underneath the bone) will be separated from the os and carefully cutting open to expose the brain.
Excess fluid will be immune to flow out of the encephalon, if needed. Microsurgical instruments, such equally a surgical microscope to magnify the area existence treated, may exist used. This tin enable the surgeon a ameliorate view of the encephalon structures and distinguish betwixt abnormal tissue and good for you tissue. Tissue samples may exist sent to the lab for testing.
A device, such equally a drain or a special blazon of monitor, may be placed in the brain tissue to measure the force per unit area inside the skull, or intracranial pressure (ICP). ICP is pressure created by the brain tissue, cerebral spinal fluid (CSF), and blood supply inside the closed skull.
Once the surgery is completed, the surgeon will suture (run up) the layers of tissue together.
The bone flap will be reattached using plates, sutures, or wires.
If a tumor or an infection is found in the bone, the flap may not be replaced. Besides, if decompression (to reduce force per unit area in the encephalon) is required, the bone flap may non be replaced.
The skin incision (scalp) will exist airtight with sutures or surgical staples.
A sterile bandage or dressing will exist applied over the incision.

Later on the procedure

In the hospital

Immediately after the procedure, you will exist taken to a recovery room for ascertainment before being taken to the intensive care unit (ICU) to exist closely monitored. Or, you may be taken direct to the ICU from the operating room.

In the ICU, you may be given medicine to decrease the brain swelling.

Your recovery process volition vary depending upon the type of procedure done and the type of anesthesia given. One time your blood pressure, pulse, and breathing are stable and you are alarm, you may be taken to the ICU or your hospital room.

Afterward staying in the ICU, you will motion to a room on a neurosurgical nursing unit in the hospital. You will remain in the infirmary for several more days.

You may need oxygen for a period of time later on surgery. More often than not, the oxygen volition be discontinued earlier yous go home.

Y'all will be taught deep-breathing exercises to aid re-aggrandize the lungs and forestall pneumonia.

Frequent neurological checks volition be done by the nursing and medical staff to test your encephalon function and to brand sure your body systems are functioning properly later your surgery. You will be asked to follow a variety of basic commands, such as moving your arms and legs, to appraise your brain part. Your pupils will be checked with a flash lite, and you will be asked questions to appraise your orientation (such every bit your proper name, the date, and where you are). The strength of your arms and legs volition as well be tested.

The head of your bed may be elevated to prevent swelling of your confront and caput. Some swelling is normal.

You will be encouraged to move around as tolerated while in bed and to leave of bed and walk around, with assistance at beginning, equally your strength improves. A physical therapist (PT) may be asked to evaluate your strength, balance, and mobility, and requite y'all suggestions for exercises to exercise both in the hospital and at home.

You will likely have sequential compression devices (SCDs) placed on your legs while y'all are in bed to preclude claret clot germination. SCDs take an air compressor that slowly pumps air into and out of fitted sleeves that are placed on the legs. They aid prevent blood clots from forming by passively compressing the leg veins to keep blood moving.

Depending on your state of affairs, y'all may be given liquids to drink a few hours later on surgery. Your diet may be gradually changed to include more solid foods equally you tin handle them.

You may have a catheter in your bladder to bleed your urine for a twenty-four hours or and so, or until you are able to go out of bed and move effectually. Be sure to report whatsoever painful urination or other urinary symptoms that occur after the catheter is removed, as these may exist signs of an infection that can be treated.

Depending on your condition, you may be transferred to a rehabilitation facility for a period of time to regain your strength.

Before yous are discharged from the hospital, arrangements will exist made for a follow-up visit with your doctor. Your doctor volition likewise give you instructions for home care.

At home

One time y'all are dwelling, it is important to keep the incision clean and dry out. Your doctor volition give y'all specific bathing instructions. If stitches or surgical staples are used, they will exist removed during a follow-up office visit. If adhesive strips are used, proceed them dry and they will fall off inside a few days.

You may choose to wear a loose turban or hat over the incision. You lot should non clothing a wig until the incision is completely healed (about 3 to 4 weeks after surgery).

The incision and head may ache, especially with deep animate, coughing, and exertion. Take a hurting reliever for soreness equally recommended by your dr.. Aspirin or other blood thinning medicines may increase the adventure of bleeding. Exist certain to have only recommended medicines and ask if y'all are unsure.

Go along the breathing exercises used in the hospital to forbid lung infection. You volition be advised to avert exposure to upper respiratory infections (colds and flu) and irritants, such as tobacco smoke, fumes, and ecology pollution.

Y'all should gradually increment your physical activity as you tin handle them. It may accept several weeks to render to your previous level of energy and forcefulness.

Yous may be instructed to avoid lifting heavy items for several weeks to prevent strain on your surgical incision.

Practice non drive until your medico gives you lot permission.

Telephone call your doctor to written report any of the post-obit:

Fever or chills
Redness, swelling, drainage, or haemorrhage or other drainage from the incision site or face
Increased hurting around the incision site
Vision changes
Confusion or excessive sleepiness
Weakness of your arms or legs
Trouble with speech
Trouble breathing, breast pain, anxiety, or modify in mental status
Green, yellow, or blood-tinged sputum (phlegm)
Seizure activity

Following a craniotomy, your doctor may requite yous other instructions, depending on your particular situation.
