Thyroid and Parathyroid

Hyperthyroidism and Graves’ disease

Hyperthyroidism (overactive thyroid) occurs when the body produces too much of the thyroid hormone, thyroxine. Causes of hyperthyroidism include Graves’ disease or nodules in the thyroid gland. Graves’ disease is an autoimmune disorder, wherein your own body’s immune system makes an antibody that causes the thyroid to produce too much hormone, resulting in hyperthyroidism. Excess ...

Neck dissection

When thyroid cancer spreads, it typically spreads to the lymph nodes in the neck, first. When thyroid cancer spreads to the lymph nodes, they are removed at the time of surgery (thyroidectomy). The neck is separated into compartments; which lymph nodes need to be removed depends on which compartments are at risk of harboring thyroid ... Read More »

Thyroid lobectomy

Thyroid lobectomy is surgery that removes either the right or left half of the thyroid gland. The remaining half of the thyroid gland continues to secrete thyroid hormone normally. This surgery is often done for nodules that are benign or when the risk of cancer is lower. It may also be performed for some small ... Read More »

Minimally invasive parathyroidectomy

This is surgery to remove the parathyroid glands or parathyroid tumors. Parathyroid glands are located in the neck, behind the thyroid gland. This surgery treats the following conditions: ● Familial hyperparathyroidism ● Multiple endocrine neoplasia, type 1 (MEN1) ● Multiple endocrine neoplasia, type 2A (MEN 2A) ● Parathyroid carcinoma ● Primary hyperparathyroidism ● Reoperative parathyroid ...

Tertiary hyperparathyroidism

Tertiary hyperparathyroidism often occurs in patients who have had a kidney transplant or require dialysis for their kidney disease. In these cases, the parathyroid glands do not respond appropriately to the normal or high levels of calcium in the blood. This results in high levels of parathyroid hormone, which can cause kidney stones, osteoporosis and ... Read More »

Total thyroidectomy

Total thyroidectomy is the surgical removal of the entire thyroid gland. This surgery is done for benign goiters, multiple nodules, Graves’ disease and thyroid cancers. When done at a high-volume center, such as Keck Medical Center of USC, the risks are low. Some risks that can occur include voice hoarseness and hypoparathyroidism. After a total ... Read More »

Secondary hyperparathyroidism

Hyperparathyroidism means that the level of parathyroid hormone measured in the blood is high. Parathyroid hormone is largely responsible for keeping the calcium level balanced. When there is more parathyroid hormone, the parathyroid glands are trying to raise the calcium level. Hyperparathyroidism is associated with a variety of symptoms, including osteoporosis, kidney stones, stomach pain, ... Read More »

Parathyroid hyperplasia

Parathyroid hyperplasia is when all four of the parathyroid glands are enlarged and overly secreting hormone. Hyperparathyroidism means that the level of parathyroid hormone measured in the blood is high. Parathyroid hormone is largely responsible for keeping the calcium level balanced. When there is more parathyroid hormone, the parathyroid glands are trying to raise the ... Read More »

Parathyroid adenoma

Parathyroid adenoma is a benign tumor of a parathyroid gland that makes too much parathyroid hormone. Because the parathyroid hormone is largely responsible for keeping calcium levels in balance, too much of the hormone may result in elevated calcium levels in the body, which can be high or still within the normal range on blood ...

Primary hyperparathyroidism

Hyperparathyroidism means that the level of parathyroid hormone measured in the blood is high. Parathyroid hormone is largely responsible for keeping the calcium level balanced. The most common manifestation is high blood calcium levels, but sometimes, calcium levels are normal. Hyperparathyroidism is associated with a variety of symptoms, including osteoporosis, kidney stones, stomach pain, fatigue, ... Read More »
