| Procedure
description
A posterior cervical laminectomy
for tumor is generally performed to remove as much tumor as
possible from within or surrounding the spinal cord.
The patient is lying on their abdomen, with their head in
a Mayfield head holder (pins in a clamp hold the head in place).
A linear incision is made in the back of the neck, in a vertical
(up and down) manner. The surgeon will then dissect
down, through the subcutaneous tissues, to the fascia (firm
membrane) overlying the spinous processes ( bones protruding
from the back of the spine). The surgeon will then pull
the muscle away from the bones, exposing the extent of the
roof of the spinal canal on both sides. Generally, under
microscopic vision, the surgeon will drill or bite away the
laminae (the bone covering the spinal cord). At this
point, the dura, which is a tough membrane covering the cord,
is opened. The tumor may be seen compressing the cord,
or it may be buried within the spinal cord. If it is
within the cord, the surgeon must open up the spinal cord,
dissecting through normal tissue, to get to the tumor.
This will result in some type of deficit, and the surgeon
will use their best judgement to determine which approach
is likely to cause the least damage to the cord.
Following the removal of as much tumor as possible, the surgeon
will close the spine. The dura will be closed with suture.
The surgeon will then close the various muscle and skin layers
with suture, and the skin with suture or staples. The
wound is then dressed in a sterile manner.
Procedure Risks
Posterior cervical laminectomy
with tumor removal has risks. These can be broken
down into two categories, 1) those related to the operative
site, and 2) those related to the risks of anesthesia.
Risks related
to the operative site:
Surgical
Exposure: The
patient is placed in a prone position (on their abdomen),
with the head fixed in Mayfield head pins. This is
a clamp which fixes the head in position. This is
an extremely safe device, but there can be potential lacerations
in the skin, as well as infection. In this position,
there can be pressure sores, pressure injuries to nerves,
and injury to the eyes as a result of pressure to them.
During surgical dissection, injury to muscle surrounding
the spine can occur.
Spinal Cord/Nerve
Root injuries: If
there is any injury to the spinal cord or nerve roots, the
consequences may involve loss of sensation, increased burning
sensation, paralysis, weakness, loss of bowel, bladder,
sexual function. There may be a spinal fluid leak
postoperatively, as the covering of the cord (dura) is widely
opened during the procedure to gain access to the tumor.
Although the surgeon will attempt to remove as much of the
tumor as possible, there may be a small or large amount
of tumor left behind. This may be due to adherence
of tumor to the surroundiing spinal cord, or because of
the blending of tumor with cord, resulting in no definite
boundary. Persistence or regrowth of tumor is a possibility.
Control of the diaphragm responsible for breathing, eminates
from the upper cervical spinal cord. If this area
is damaged, the patient may need a permanent tracheostomy
(hole in the windpipe), to provide a diversion of the route
air takes to enter the lungs. A feeding tube may also
be needed, postoperatively.
General
Risks: These
include such general difficulties, such as bleeding, infection,
stroke, paralysis, coma and death. The scar on the
neck may be tender, or may heal in an unpleasant manner.
There is also the possibility that the surgery may not relieve
the symptoms for which the procedure was performed.
The problem for which the surgery was performed may recur,
requiring additional surgery in the future. In addition,
although every attempt is made to protect all areas of the
body from pressure on nerves, skin and bones, injuries to
these areas can occur, particularly with prolonged cases.
Risks of
Anesthesia: Blood
clots in the legs, heart attacks, reaction to the anesthetic,
reaction to blood transfusion, if it given.
Post-operative care:
You may be required to wear
a soft or firm cervical collar postoperatively. There
shall be no bending, twisting, or heavy lifting for several
weeks after surgery. Physical therapy may or may not
be implicated. Your doctor will gradually ease your
work restrictions, depending on your progress.
Remember to keep the wound
dry and clean. Notify your surgeon of any drainage
or temperatures greater than 101 Fahrenheit.
You may experience some continuing
incisional pain and occasional spasms in the back of your
neck from time to time. There are several steps
you can take which will help speed your recovery as well
as give you the best chance for a successful outcome.
- Immediately upon discharge,
contact our office and set up an appointment for staple
removal is one has not already been set up.
- Wear the collar given to
you by your surgeon. It should be worn continuously
except when showering or shaving, unless instructed otherwise
by your surgeon.
- Do no drive until cleared
with your physician.
- Avoid riding in a car more
than 50 miles.
- When shaving, avoid tilting
your neck back. When washing your hair, do it in
the shower and not in the sink.
- Begin an exercise program
of walking to gain strength.
- Lift nothing heavier than
one pound (one quart of milk).
- No jogging, weight lifting,
or other heavy exercise for now.
- Do not raise your arms above
your head.
- You may shower with the
incision covered.
- You may engage in sexual
relations.
- In doing any activity in
which you notice an increased amount of neck, shoulder
or arm pain, STOP. Your body is telling you that
you are doing too much.
- If you notice any swelling,
redness or opening of the incision, notify your surgeon
immediately. If any clear or purulent fluid drains
from your neck, notify your surgeon immediately.
- If you develop fever
or a stiff neck, notify your surgeon immediately.
- If you have any questions,
please do not hesitate to call your surgeon.
- Take your temperature at
4:00 PM daily until clips/sutures are removed.
- Take your medications as
prescribed by your physician.
- It takes 6-18 months for
a nerve to heal. You may have numbness, tingling,
creepy crawly sensations or fleeting pain during this
time.
