    Parathyroid Surgery

    Parathyroid surgery is often recommended when tests indicate hypercalcemia, an elevated calcium level in your blood. Typically high calcium level has no observable symptoms. When high calcium is the result of hyperparathyroidism (too much parathyroid hormone) your bones will, in time, thin out. This puts you at increasing risk of fractured bones.

    The parathyroid glands are four small glands located in the neck. They are usually situated behind the thyroid gland. These glands regulate the body's calcium: the calcium in the blood stream , the calcium in your bones and the calcium absorbed by the intestine from your diet.

    These four tiny glands really have a very important role in the body's metabolism. The calcium is important in how the heart works and in bone density. You obviously need strong, dense bones to have a healthy spine and to protect yourself from fractures. The parathyroid glands help build strong bones by controlling the calcium absorbed from the intestine and used to build strong bones.

    In hyperparathyroidism, usually one of the four glands produces too much parathyroid hormone. The function of this hormone is to dissolve calcium out of the bones; this in turn increases the calcium in the blood stream. The parathyroid hormone also increases the calcium absorbed from the intestine. The increased calcium affects heart function, memory and depression, and can cause kidney stones and stomach ulcers.

    Blood tests can be done to prove that it is the parathyroid glands responsible for the high calcium. Special nuclear medicine X-rays also can prove which one of the four glands is the culprit! Occassionally, all four of the glands are malfunctioning (parathyroid hyperplasia) rather than just one of the glands (parathyroid adenoma).

    Surgery for hyperparathyroidism removes the malfunctioning gland. The remaining glands resume normal functioning and your calcium returns to normal. In the operating room, Dr. Kloss uses a special nuclear probe (a Geiger counter) to locate the malfunctioning gland. In this way, the surgery is accomplished more quickly, more safely and limited to the malfunctioning gland(s) rather than exploring all four glands.

    Dr. Kloss is a board certified surgeon and has a special interest in parathyroid surgery. He uses all the technological tricks that have come along to make the surgery safer and faster for you: a special breathing tube that makes the risks of nerve damage less; optical magnifiers which make seeing these tiny little glands easier; and the "radio guided" surgical technique to help locate the diseased gland.
