Expert Thyroid and Parathyroid Surgery in Darwin by Dr. Maran
Thyroidectomy
A thyroidectomy is surgery to remove all or part of the thyroid gland. If a person has the entire gland removed, they will need to take tablets to replace the thyroid hormone for the rest of their life.
Your thyroid is a butterfly-shaped gland located at the base of your neck. It produces hormones that regulate every aspect of your metabolism, from your heart rate to how quickly you burn calories.
Thyroidectomy is used to treat thyroid disorders, such as cancer, noncancerous enlargement of the thyroid (goiter) and overactive thyroid (hyperthyroidism).
Parathyroidectomy
Parathyroidectomy is the surgical removal of one or more parathyroid glands.
The parathyroid glands are four rice-sized glands located on back of the thyroid gland in the neck. The parathyroid glands make parathyroid hormone (PTH), which controls the levels of calcium in the body. Sometimes one or more of these glands become hyperactive and secretes more of this hormone resulting in higher-than-normal calcium levels and certain symptoms that require intervention.
