Parathyroid Surgery

Parathyroid Surgery

The Thyroid Head and Neck Surgery Centre is a one-stop facility that provides you with a comprehensive evaluation of Thyroid & Parathyroid disease.

Thyroid & Neck Ultrasound

An ultrasound is an important bed-side non-invasive scan that allows us to detect and locate abnormal parathyroid glands called parathyroid adenomas.

The ultrasound is also very useful in evaluating thyroid nodules, parotid and salivary gland tumours and swollen lymph nodes.

Diagnostic Radiology

A Sestamibi-SPECT/CT, along with an ultrasound, are the two most important investigations to detect and locate abnormal parathyroid glands.

Minimally Invasive Parathyroidectomy (MIP)

Accurate pre-operative localisation of an abnormal parathyroid gland allows us to perform a Minimally Invasive Parathyroidectomy (MIP) through a small 2 - 2.5cm neck incision. Benefits of an MIP are significantly less postoperative pain, faster recovery and an excellent aesthetic outcome.

Parathyroid surgery is very safe with surgical risks, in particular of voice damage of less than 1% in experienced hands.

What is Hyperparathyroidism?

Though many are aware of the existence of the thyroid, a gland responsible for the regulation of organ and cellular function, few are familiar with four small glands that reside just behind the thyroid, called the parathyroid glands, whose function, though completely distinct from the thyroid, is no less important.

The parathyroid glands produce parathyroid hormone, required for the precise regulation of blood calcium, which in turn ensures the normal function of many organ systems as well. Indeed abnormally high parathyroid hormone levels, a condition called hyperparathyroidism can cause debilitating symptoms more severe, and more morbid than problems associated with thyroid hormone disorders.

What are the symptoms?

Many patients may be completely asymptomatic, or have very mild symptoms. Symptomatic patients, however, may present with one or more of the following:

  • Ureteric colic and urinary symptoms from kidney stones
  • Bone pain and fractures from decreased bone mineral density and osteoporosis
  • Abdominal pain from stomach ulcers and inflammation of the pancreas
  • Neurological symptoms including fatigue, poor concentration and depression

What are the causes?

The most common cause of hyperparathyroidism is from a parathyroid adenoma, a benign tumour of one of the four parathyroid glands that secretes excess parathyroid hormone. This solitary parathyroid adenoma accounts for 85% of cases of hyperparathyroidism. In the remaining 10 – 15% of cases the excess hormone production comes from two or four abnormal glands, called double adenomas and parathyroid hyperplasia respectively. Parathyroid cancer as a cause of hyperparathyroidism is exceedingly rare.

What are the consequences?

The abnormally high blood calcium levels cause the development of:

  • Kidney stones from elevated urine calcium levels
  • Osteoporosis from excessive calcium absorption from bones, predisposing to easy bone fractures
  • Stomach ulcers and acute inflammation of the pancreas
  • Neurological symptoms, particularly fatigue and depression
  • Abnormal cardiac rhythm and cardiovascular disease
Minimally Invasive Parathyroidectomy (MIP)

Surgery is the definitive treatment for hyperparathyroidism. Successful removal of the diseased parathyroid gland cures the patient of the disease, and reverses many of the preceding harmful effects of excess circulating parathyroid hormone. Minimally Invasive Parathyroidectomy (MIP) is the gold standard treatment for parathyroid adenomas.

Safety & Recovery

Parathyroid surgery, as for thyroid surgery, is very safe, with surgical risks of less than 1% if performed by an experienced parathyroid surgeon.

Recovery is quick with most patients going home either on the day of surgery or after an overnight stay.
