Parathyroid Surgery Patient Info Sheet

What are the parathyroids?

The parathyroids are four tiny glands in your neck, two on each side of your thyroid gland. They make parathyroid hormone (PTH) which controls the level of calcium in the blood. Calcium is very important for the normal functioning of muscles, nerves, and bones. It is absorbed through the intestines and stored in the bones. Parathyroid hormone raises blood levels of calcium by increasing intestinal absorption of calcium, and by dissolving calcium from the bone into the bloodstream.

What is hyperparathyroidism?

Some people make too much parathyroid hormone, a condition called hyperparathyroidism. This condition is most common in middle-aged women,
but can occur in men or women at any age and can run in families. In 9 of 10
patients with hyperparathyroidism, the cause is a single benign tumour. In one
of 10, all four parathyroids are enlarged. Cancer is exceedingly rare.

What are the symptoms of hyperparathyroidism?

The body does not like having blood calcium levels too high, and tells you in a
number of ways.

Hyperparathyroidism can cause

. weak bones, called osteoporosis, which can lead to fractures
. kidney stones, renal impairment
. high blood pressure
. abdominal pain
. increased frequency of urination
. constipation
. stomach ulcers and pancreatitis
. psychiatric problems
. arrythmias and heart disease
. difficult to control blood sugar if you are diabetic
Other symptoms are much more subtle, and include
. weakness and fatigue, loss of energy
. memory and concentration problems
. muscle and joint aches and pains
. abdominal and back pains
. feeling "older" than you should
. mood swings or depression

IMPORTANT ***These non-specific, vague symptoms happen with high calcium no matter if it's only slightly high or very high. High calcium is never normal and should not be "watched." These vague symptoms improve in 85% of patients after successful parathyroid surgery. Most patients who thought they had no symptoms, in retrospect, realize they did have these symptoms and feel much better within weeks after surgery. They frequently say things like: "I feel 10 years younger," and "you have given me a new body." Bone density also improves, reducing the risk of fractures.***

Treatment of hyperparathyroidism

The only effective treatment for hyperparathyroidism is surgery to remove the overactive gland(s). In the hands of an experienced endocrine surgeon, surgery
can cure the condition in 98% of cases. There is no effective non-surgical treatment
for hyperparathyroidism. Before surgery, you will have a sestamibi scan (a painless scanning test) and a neck ultrasound to see if there is one enlarged gland that can
be located. If the abnormal gland is seen, you can have "parathyroid mini-surgery" though a very small incision, and possibly go home the same day. Even if the gland
is not seen, it can still be found at surgery in 98% of cases. The surgery takes about
one hour, and the incision is on your neck. You will be completely asleep during the operation, and will feel no pain. Recovery is quick, with most patients going home the same day or the next day, and feeling very little discomfort. Most are back at work
in a few days!

Frequently Asked Questions

Is there any other treatment besides surgery?

No. Surgery is the only effective treatment of hyperparathyroidism.

What if I don't have the surgery?

Even if you think you have no symptoms, you will almost certainly feel much better
after you are cured. If you don't have surgery, you will continue to have high blood calcium, and many symptoms listed above. Without surgery, your bones will continue
to become weaker, and possibly break. There is evidence of increased risk of high
blood pressure, stroke, heart disease, and even shorter life expectancy, from
untreated hyperparathyroidism.

How long will I be hospitalized?

Most patients are able to go home the same day (after parathyroid "mini-surgery")
or the following day.

What type of anesthesia will I have?

You will have a general anesthesia. You will be completely asleep during the operation.

When will I know the results of the surgery?

The calcium levels generally return to normal within 12-48 hours of surgery.

Will I have a scar?

Yes. All surgery causes scarring, and how a patient scars is dependent on the individual. However, there are some techniques that surgeons use to minimize scarring. These techniques include careful incision placement and hypoallergenic suture material (to avoid inflammation). For parathyroid "mini-surgery," the scar is about 1-2 inches. If you need a full neck exploration, it will be bigger. As a general rule, no matter which operation you need, it is unusual to have a very noticeable scar after six months. Scars continue to fade for three years.

Will I have pain after the operation?

All operations involve some discomfort, but most patients are surprised at how little pain they feel after this operation. Although you should be able to eat and drink normally, the main complaint is sore throat and discomfort with swallowing for 1-2 days. Most patients take Panadol or Nurofen to keep them comfortable at home. You will have a prescription for something stronger for the first few days in case you need it, but beware prescription pain medicine can make you drowsy and constipated, so do not drive, drink lots of water and eat plenty of fruits and vegetables.

Will I have stitches?

You will have stitches on the inside that dissolve on their own. You will have a waterproof Comfeel dressing so that you can shower or bathe as usual (but do not submerge the incision for 5 days). Leave the dressing in place until your first post-operative visit, where it will be removed.

Will I have any physical restrictions after my surgery?

Your activity level depends on the amount of discomfort you experience. Many patients have resumed golf or tennis within a week after the operation. Most patients return to work in a week, and you are able to drive as soon as your head can be turned comfortably without prescription pain pills (this limitation is for driver safety).

What are the possible complications of parathyroid surgery?

The nerves that control your voice are very closely associated with the parathyroid glands. Temporary voice changes are not uncommon, but usually resolve within weeks to months. In 1 in 100 parathyroid operations, the nerves that control the voice are permanently affected. When this occurs, the main difficulties are projection of the voice and production of high pitched sounds. It is usually described as hoarse, but will not necessarily be considered abnormal by strangers.
Sometimes the surgery will not cure the hyperparathyroidism. In the hands of an experienced endocrine surgeon, failure to cure occurs in fewer than 2 in 100 patients. Sometimes the normal parathyroid glands become "lazy" because the abnormal gland was doing all the work. They may take some time to recover, so some patients require extra calcium tablets on a temporary basis. Rarely, the parathyroids do not recover, and calcium and vitamin D may be needed on a permanent basis. In rare instances, the tumour can recur. Lifelong yearly blood tests are recommended.
There is a small risk of bleeding into the wound. If this happens, it may be necessary to have a second operation to evacuate the blood so it does not interfere with your breathing. Infection is relatively uncommon, and is easy to treat should it occur.


As with anything in life, there are risks to surgery. These risks are weighed against the risks of not having surgery. Listed below are some of the possible complications of surgery. Risks include, but are not limited to:

. Permanent voice hoarseness...........<1%
. Failure to cure the hyperparathyroidism......<2%
. Permanent hypoparathyroidism........< % (0% for mini-surgery)
. Infection of Incision........................................... Less than 1%
. Haematoma or Bleeding..................Less than 1%
. Seroma (fluid collection)..........1% (temporary)
. Swelling and black/blue....................................About 5% (temporary)
. Keloid or overgrown scar.........rare

Other unforeseen risks

You will require general anaesthetic, given by a specialist anaesthetist. Risk of a serious complication in a healthy person is very rare. Potential risks include, but are not limited to:

. Heart problems (death, heart attack, arrhythmias)
. Lung problems (pneumonia, wheezing)
. Blood clots (stroke, clots in leg veins or lungs)
. Drug reactions (also possible with local anaesthetic)
. Chipped teeth
. Other unforeseen risks

You will meet the anaesthetist before your operation and have the chance to discuss these further.


  • Please shower at home the evening before surgery or in the morning.
  • Please do not shave the surgical site! It will be done for you if necessary. Shaving yourself may increase the risk of infection.
  • For morning surgery, Do Not Eat or Drink anything after midnight the night before surgery unless otherwise instructed. This includes coffee, tea, water, and juice! Medication with a small sip of water is OK. For afternoon surgery, a small breakfast BEFORE 7AM is OK, and nothing after that. Your surgery may be cancelled if you do not follow these instructions.
  • Do Not Drink Alcoholic beverages 24 hours prior to your surgery.
  • Do Not Smoke for 4 weeks before surgery or your risk of serious complications increases.
  • Ask us if you are permitted to take your routine medications (such as those for heart, blood pressure, or insulin etc.) before arriving for surgery.
  • Stop aspirin, warfarin, anti-inflammatories, or any other blood thinner 5-7 days prior to surgery
  • Do Not bring valuables such as money, jewelry etc. Do not wear make-up.
  • Bring toiletries and loose fitting, comfortable clothing to wear upon discharge.
  • You will be required to remove contact lenses, jewelry, dentures, and wigs
  • Arrange for a responsible adult to drive you home after discharge.
  • Notify us if there is a change in your condition prior to surgery (such as a cold, cough, fever or infection). If severe, your surgery may need to be postponed for your safety.
  • Stop all herbal medications 4 weeks before surgery unless discussed beforehand. Especially Ginseng, Garlic, and Gingko, or St. John's Wort, which increase the risk of bleeding.


  • You will have a waterproof comfeel dressing on. Please leave it in place until the first post-operative visit.
  • You may shower 24 hours after surgery and pat dry over the dressing
  • If the dressing comes off prior to your first doctor's visit, you may apply a new dressing. If it is more than 3 days since the surgery, it's also OK to leave the dressing off
  • Some numbness, tightness, swelling, and bruising around the incision is normal.
  • For the best cosmetic result, keep your incision out of the sun for one year after surgery.
  • Call your surgeon or your local doctor if you have a temperature >38.3 or chills, increasing pain, heat, and redness around the incision, or a foul-smelling or creamy discharge. These are all signs of an infection that may require antibiotic treatment or drainage.


  • On the day of your surgery, report to reception, MPH, Level 1.
  • If you have not already done so, you will meet your anaesthetist
  • You may need a blood test or ECG prior to surgery
  • After the operation, you will some time in the recovery room before going to the ward

After discharge, you are not permitted to:

  • Drive a Car nor operate power equipment
  • Drink Alcoholic Beverages
  • Sign important papers

The above are not permitted on the day of surgery, nor while taking any prescription pain medication. Instructions regarding safe resumption of the above activities will be provided by your surgeon.

Post-Operative Instructions for Parathyroid Surgery

Below are general instructions for patients who have had thyroid or parathyroid surgery. Since individual circumstances may vary, it is important that you discuss your individual post operative care with us.

Monitoring Your Progress

You should feel improvement every day after surgery. If you have any questions regarding your progress, call our office. You should make a follow up appointment approximately 1-2 weeks after your surgery.


Your incision is covered with a waterproof protective dressing. You can shower and wash your hair as usual, but do not soak or scrub the dressing. After showering, pat dry. Your dressing will be removed at your first post-operative visit. If you experience itching once the dressing is off, you may apply lotion to the scar. You might notice bruising around your incision or upper chest and slight swelling behind the scar when you are upright. In addition, the scar may become pink and hard. This hardening will peak at about 3 weeks and may result in some tightness or difficulty swallowing, which will disappear over the next 3 to 4 months. You will also notice some numbness of the skin of your neck. This will gradually improve over time.


The main complaint following parathyroid surgery is discomfort with swallowing. Some people experience a dull ache, while others feel a sharp pain. This should not keep you from eating anything you want, but the pain can be annoying for a day or two. Nurofen or or Panadol is generally enough to control this pain. Some people prefer Panadeine, but in general, stronger medications are not necessary for long. You may feel like you have phlegm in your throat. This is usually because there was a tube in your windpipe while you were asleep that caused irritation that you perceive as phlegm. You will notice that if you cough, very little phlegm will come up. This should clear up in 4 to 5 days.

Voice Changes

Your voice may go through some temporary changes with fluctuations in volume and clarity (hoarseness). Temporary changes are quite common. Generally, it will be better in the mornings and "tire" toward the end of the day. This can last for variable periods of time, but should clear in 4-6 months at most. There is a small (1/100) risk of permanent hoarseness.

Hypocalcemia and Bone Health

Your bones have been starved of calcium during the time you have had hyperparathyroidism, and will now have the chance to grow strong again. After successful parathyroid surgery, I recommend you take Caltrate Plus twice a day (available at any chemist) to promote healthy bones. In addition to these supplements, an exercise routine using weights is also recommended
In about 20% of patients who have parathyroid surgery, the remaining parathyroid glands have become lazy, and do not function properly immediately after surgery. . This is usually temporary and causes the blood calcium level to drop below normal (hypocalcaemia). Symptoms of hypocalcaemia include numbness and tingling in your hands, soles of your feet and around your lips. Some patients experience a "crawling" sensation in the skin, muscle cramps or headaches. These symptoms appear between 24 and 48 hours after surgery. It is rare for them to appear after 72 hours.
Hypocalcaemia is treated with extra calcium tablets. You should purchase Calcium with Vitamin D (Caltrate) tablets before surgery so you have them at home. If you feel you need it, take two extra tablets (there is no danger in taking it, even if you do not need it.) The symptoms of tingling/numbness should improve within 30 minutes of taking the tablets. If they do not disappear, you should call my office.
You should repeat the dose whenever the symptoms return. This may mean that you are taking as many as 2 tablets every 3 hours. It is important that you keep us informed. The hypocalcaemia should disappear over a few weeks. If it does not, let us know.

CONTACT MY OFFICE for any of the following symptoms:

. Fever >38.3 or chills
. Increasing pain or redness around incision
. Difficulty breathing
. Tingling around the lips or fingertips not relieved by calcium tablets
. Severe muscle cramps


Insurance rebates have not kept pace with the cost of running a medical practice. As a consequence, there will be a gap to pay for the surgical fee and for the anaesthetist. Your insurance company might also charge you an excess for a hospital admission. We will advise you about expected out-of pocket costs not covered by insurance. If these costs represent an undue hardship for you, please discuss them with us.


We are here to help you. If you have any questions, please ask. It is often helpful to bring a family member with you to a consultation, or to write questions down so you won't forget them.
