| Are
there other means of treatment?
Surgery is definitely required for a diagnosis of thyroid cancer
or the possibility of thyroid cancer (see Thyroid
Cancer brochure). In the absence of a possibility of thyroid
cancer, there may be non-surgical options of therapy depending on
the diagnosis. You should discuss other options for therapy with
your physician.
How should I be evaluated prior
to the operation?
As for other operations, all patients considering thyroid
surgery should be evaluated preoperatively with a thorough and comprehensive
medical history and physical exam, including cardiopulmonary (heart)
evaluation. Ordering an EKG and a chest x-ray prior to thyroidectomy
for patients over 45 years of age or who are symptomatic from cardiac
disease is often recommended. Blood tests are performed to determine
if a bleeding disorder is present. Any patients who has had any
change in voice or who have had a previous neck operation should
have their vocal cord function evaluated preoperatively. This is
necessary to determine whether the recurrent laryngeal nerve that
supplies the vocal cord muscles is functioning normally. Finally,
if the thyroid cancer diagnosis is the rare medullary thyroid cancer,
it is important to evaluate patients with coexisting adrenal tumors
(pheochromocytomas) and for hypercalcemia and hyperparathyroidism
(see Thyroid
Cancer brochure).
How do I select a surgeon?
In general, thyroid surgery is best performed by a surgeon who has
received special training and who performs thyroid surgery on a
regular basis. Patients should ask their referring physician where
he or she would go to have a thyroid operation or where he or she
would send a family member, since the complication rate of thyroid
operations is lower when the operation is done by a surgeon who
does a considerable number of thyroid operations each year.
What are the risks of the operation?
The most serious possible risks of thyroid surgery include: 1) bleeding
that can cause acute respiratory distress, 2) injury to the recurrent
laryngeal nerve that can cause permanent hoarseness, and 3) damage
to the parathyroid glands that control calcium levels in the body,
causing hypoparathyroidism. These complications occur more frequently
in patients with extensive lymph node involvement and invasive tumors,
in patients requiring a second thyroid surgery, and in patients
with large goiters that go below the collarbone. Complications occur
more frequently when the surgeon is not very experienced doing thyroid
operations. Overall the risk of any serious complication should
be less than 2%. However, the risk of complications discussed with
the patient should be the particular surgeon’s risks rather
than that quoted in the literature. Prior to surgery, patients should
receive informed consent from the surgeon about the reasons for
the operation, the alternative methods of treatment, and the potential
risks and benefits of the operation.
How much of my thyroid gland needs
to be removed?
Patients should discuss with the surgeon what operation on the thyroid
is to be performed, such as lobectomy or total thyroidectomy, and
the reasons why such a procedure is recommended. For patients with
papillary or follicular thyroid cancer many, but not all, surgeons
recommend total or near-total thyroidectomy when they believe that
subsequent treatment such as that with radioactive iodine might
be beneficial (see Thyroid
Cancer brochure). For patients with large (>1.5 cm)
primary tumors and for any medullary thyroid cancer, more extensive
lymph node dissection is necessary to remove possibly involved lymph
node metastases.
Thyroidectomy is an excellent method to treat patients with multiple
benign thyroid nodules and/or large goiters, whether overactive
or functioning normally. For patients with one-sided nodules, whether
overactive or functioning normally, thyroid lobectomy successfully
corrects these problems. For patients with hyperthyroidism due to
Graves’ disease or multinodular goiters (see Hyperthyroidism
brochure), many surgeons recommend a total thyroid lobectomy
on the side with the largest nodules or goiter and a subtotal or
near total resection of the opposite lobe.
What can I expect once I decide
to proceed with surgery?
Once you have met with the surgeon and decided to proceed
with surgery, you will be scheduled for your pre-op evaluation (see
above) and will meet with the anesthesiologist (the person who will
put you to sleep during the surgery). You should have nothing to
eat or drink after midnight on the day before surgery and should
leave valuables and jewelry at home. The surgery usually takes 2-2½
hours, after which time you will slowly wake up in the recovery
room. There may be a surgical drain in the incision in your neck
(which will be removed the morning after the surgery) and your throat
may be sore because of the breathing tube placed during the operation.
Once you are fully awake, you will be moved to a bed in a hospital
room where you will be able to eat and drink as you wish. Most patients
having thyroid operations are hospitalized for about 24 hours and
can be discharged on the morning following the operation. Normal
activity can begin on the first postoperative day. Vigorous sports,
such as swimming, and activities that include heavy lifting should
be delayed for at least ten days.
Will I be normal after surgery?
Yes. Once you have recovered from the effects of thyroid surgery,
you will usually be able to doing anything that you could do prior
to surgery. Many patients become hypothyroid following thyroid surgery,
requiring treatment with thyroid hormone (see Hypothyroidism
brochure). This is especially true if you had surgery for thyroid
cancer. In addition, your doctor may recommend follow-up therapy
with radioactive iodine if you have thyroid cancer prior to starting
thyroid hormone therapy (see Thyroid
Cancer brochure).
