What is a radical neck dissection? The surgeon removes a block of tissue from the collarbone to the jaw and from the front to the back of the neck. The large muscle on the side of the neck that is used for rotating, flexing or extending the neck is also taken out, along with the major vein on the side of the neck. Sometimes, a less drastic operation, called a supraomohyoid neck dissection is done. This takes out only the lymph nodes, the tissue surrounding the nodes and a muscle at the front of the neck. Another technique, called a functional neck dissection, saves the muscles of the neck, taking out only the lymph nodes and tissues surrounding them.
What kind of incision is made with a radical neck dissection? The incision depends upon what the surgery is for. It can run from below the ear to the collarbone. Everything in the front of the neck on one side or on both sides may be removed. This may include the lymph nodes, blood vessels, nerves, and the salivary gland under the jawbone.

Can anything besides eating and not eating make my blood sugar go up or down?

Blood sugar often goes up when you have an infection the flu, the common cold, stomach upsets. Major surgery and pregnancy cause a rise. Then there are a number of drugs that tend to raise blood sugar. Caffeine, oral contraceptives, estrogen, and cortisone are the most important to know about. Emotional tension also causes blood sugar to swing upward. Besides being lowered by fasting or by insufficient food, blood sugar goes down when you exercise strenuously. Among drugs with a lowering effect are alcohol (when you don't eat while drinking), large doses of aspirin, blood-thinning drugs, barbiturates, and sulfonamides.
