Epilepsy Surgery
In recent years epilepsy surgery has become
a well recognised treatment for certain
types of epilepsy. Here are answers to some
of the questions commonly asked by patients
considering surgery.
Why is surgery used to treat
epilepsy?
Epilepsy is sometimes caused by an area of
abnormal brain tissue which triggers
seizures. This area of abnormal tissue is
referred to as an ‘epilepsy focus’. There
are many reasons why such abnormalities
occur and they may be insignificant unless
they cause seizures. If surgery can remove
the epilepsy focus, seizures can often be
prevented. The size and position of the
focus can vary. The chance of successful
surgery and the risks of complications are
different for each patient.
Surgery is usually only used where
medication fails and it is not intended to
be a substitute for medication. If surgery
is considered to be a possible treatment for
your epilepsy, extensive tests will first be
carried out. Your doctors will then discuss
with you, the possible outcomes from surgery
in your case, so that you can make an
informed choice.
How do I prepare for surgery?
When surgery is planned and you are waiting
for admission to hospital, maintain your
normal lifestyle and continue to take your
medication as prescribed. You can usually
expect to be in hospital 7-10 days so pack
nightwear, something comfortable to wear
while you are out of bed during the day and
any personal requirements. Be prepared in
case you are called in at short notice.
If you smoke, it is recommended that you try
to stop. If you are having difficulty
stopping, discuss this with your doctor.
Nicotine substitutes may be recommended.
Smoking is not permitted in hospitals. It’s
important that you don’t smoke for the 48
hours prior to surgery.
You do not need to cut or shave your hair
before you go to hospital. On the day of
surgery, only the hair around the operation
area will be shaved. The rest of your hair
will not be cut. After surgery some people
decide to trim their hair short, but others,
especially those with long hair, find they
can comb their hair to hide the surgical
cut, which is usually within the hairline.
If you are unwell in the week before
surgery, please consult your doctor.
What happens during the surgery?
You will usually be admitted to hospital for
routine tests, the day before your surgery.
On the day of surgery you will not be
allowed to eat or drink for several hours
before the operation and one hour before
going to the operating suite you will be
given a light sedative.
In the operating suite you will meet the
team of doctors and nurses caring for you.
The anaesthetist will insert a fine needle
into your vein to administer medication and
you will be taken to the operating room
where you will be anaesthetised and fall
asleep. (Some surgery is performed with the
patient awake. If this applies to you, you
will have been informed previously.)
Once asleep, your hair will be shaved over
the operation site. The skin is wiped with
antiseptic solution and drapes arranged to
keep the area sterile. The skin and muscle
are cut to expose the skull and a piece of
bone is removed. The dura (tissue covering
the brain) is cut, the brain exposed, the
area causing problems is removed and the
dura is closed. The bone is replaced and in
most cases held in position with metal
plates. After the muscle is rejoined, the
skin is usually closed with surgical
staples, which are easily removed after 7
days. When you wake you will have a small
dressing over the staples or a bandage
around your head.
What happens when I wake up?
When you wake after surgery, you will be
carefully observed and made comfortable,
with medication for pain if required. You
may have an intravenous tube in your arm to
provide fluids. After bed rest for
approximately 2 days you will be assisted to
sit out of bed and gradually begin to walk
and shower with supervision.
You will often feel very tired after your
operation. This is due to the combination of
having an operation and the time spent in
bed whilst in hospital. Although visitors
are welcome, they can tire you, so ask your
family or the nursing staff to limit
visitors if you wish.
You will usually be discharged from hospital
after 7-10 days depending on the type of
surgery you’ve had and how you are feeling.
Are there any side effects of the
surgery?
There are several serious side effects of
any brain surgery which your doctors will
discuss with you. These include bleeding,
injury to the brain and infection of the
brain or bone. Fortunately these
complications are rare. In addition, a small
number of patients will have a seizure
immediately after their operation. This does
not necessarily mean the surgery was
unsuccessful, or that seizures will
continue. It is the result of having had an
operation on the brain and usually settles
very quickly.
There are a number of common, less
significant side effects.
· Dizziness may occur after surgery. Often when patients
first get out of bed they feel dizzy and are
unsteady on their feet. This usually settles
within 24-48 hours.
· Headache and jaw ache are common after epilepsy surgery especially
around the forehead and temple. Cutting the
temporalis muscle may be the cause. This
muscle is attached to the temple at one end
and the jaw at the other, so you might
notice pain for the first few weeks when
eating or yawning. This settles in almost
all cases.
Headache can increase when the pressure
inside your head increases, as with sneezing
or straining. Since constipation is common
after an operation, bowel actions can
increase your headache.
· Swelling or bruising of the face or head near the surgery area is
also common. This reduces quickly in most
cases.
· Superficial infection of the skin may occur.
· Blurred vision may occur. It usually settles after several
weeks but may take three months. Consult
your doctor before changing your glasses
prescription.
· Sensations of ‘clunking’ at the site of the surgery do not mean the
bone has moved. It is held in place by metal
plates. Swishing noises in your head, or
feeling that fluid is present directly under
the skin are due to fluid pathways in the
brain settling down after surgery.
· Numbness occurs where skin is cut and scars form.
This decreases with time, but some numbness
may be permanent.
· Feeling depressed after surgery can be common for many
reasons. However, after epilepsy surgery up
to 30% of people have a temporary clinical
depression, which often resolves itself but
at times needs treatment. Therefore if you
are depressed or concerned about any matter,
do not hesitate to contact your neurologist.
· Other issues may cause you concern. For example,
impotence in men or dysfunction of the
menstrual cycle in women can occur. These
usually subside within a few months and are
thought to be due to temporary hormonal
disturbance. Do not be embarrassed to raise
these, or other questions with your
neurologist.
· If you have temporal lobe surgery, you may notice a
slight dip in the tissue beside your ear. If
this concerns you consult your doctor, as it
may be possible to improve this appearance.
Difficulty raising your eyebrow is usually
due to temporary nerve bruising which can
settle in three months.
What should I do when I go home?
When you go home you may feel very tired
because you have been through a stressful
experience, an operation and days with
little exercise. A balance of rest and
activity will help you to regain your normal
energy and confidence.
The following suggestions are general
guidelines, however, each person recovers at
their own pace and your doctor may suggest a
particular program of recovery for you.
Follow any instructions about pain
medication carefully and continue your
epilepsy medication as prescribed. If you
notice any unexpected symptoms such as a
fever, or changes in your general health,
please contact your neurologist.
· Wound Care
Your wound should be healed by the time you
leave hospital. During the first few weeks,
you may need to have a family member or
friend observe the suture line for signs of
redness, swelling or discharge.
You can wash your hair as usual with normal
shampoo and conditioner to keep the area
clean, but do not rub directly on the scar
for the first week. It is recommended that
you refrain from using hair dye for a
minimum of 3 weeks after surgery.
· Activity
Each day, you can expect to get up and
dressed. Aim for a good night’s sleep and
allow one or two rest periods during the day
in the early weeks as required. Daytime
sleep is not recommended if it disturbs your
night sleep.
As soon as you feel able, begin to exercise
by walking at a comfortable pace. Build to
approximately 20 minutes twice daily after
three weeks, or the target recommended by
your doctor.
Return to part time work or study might be
expected at approximately 6-8 weeks,
depending on your job, gradually increasing
to full time by 3 months if your doctor
agrees. Be patient with yourself. The rate
of improvement will vary for each person.
Continue to ensure regular sleep patterns as
you increase your activities and avoid
contact sports for 6 months.
· Follow-up
After surgery you will be followed up at a
multi-disciplinary clinic, or by your
neurosurgeon, neurologist and other members
of the health care team individually. Your
first appointment will be made approximately
3 weeks after discharge from hospital, but
you are free to contact your doctors earlier
if you feel it is necessary.
· Alcohol, Smoking and Driving
Your neurologist will advise you about
alcohol intake. The recommendations you
followed prior to surgery are likely to
continue after surgery.
Driving is not allowed for a minimum of 12
months following epilepsy surgery (providing
you are seizure free) and before you are
permitted to drive you will need the
approval of your neurologist.
It is advised that you do not continue
smoking after the operation for medical
reasons. However, if you choose to continue
you should wait at least one week after your
surgery.
· Medication
Your epilepsy medication will continue after
surgery as instructed by your neurologist.
Women taking epilepsy medication are advised
to discuss issues of contraception and
pregnancy with their neurologist.
Will epilepsy surgery change my
life?
It is not possible to anticipate exactly
what a person’s life will be like after
epilepsy surgery. People who become seizure
free will need time and perhaps support, to
adapt to the changes in their lives. Where
surgery is not as successful as anticipated
there may be disappointment. The doctors and
other health professionals in an epilepsy
surgery unit recognise that these are
important issues and offer long term follow
up and support.
Information and Support
A person considering epilepsy surgery will
have many questions. These may concern the
pre-surgery tests, the operation itself, or
the recovery period. Your neurologist,
neurosurgeon and the team of health
professionals supporting you through this
process, can provide current information
relevant to your situation. Do not hesitate
to ask for information or raise any
concerns.
You may discover that modern advances in
epilepsy surgery are not well understood in
the community and your friends or family
might express fear and concern about your
decision to have surgery. Epilepsy
Foundation staff, and Foundation members who
have experienced surgery themselves, are
very happy to speak with you or your family
when surgery is being considered. Support is
also available to help you in the months
after your operation.
The Epilepsy Foundation has a two bedroom
flat available for patients and/or their
companions, who are visiting Melbourne for
epilepsy treatment.
