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.

My mother has a diagnosis of TIAs what is that?

TIAs stands for transient ischemic attacks, often simply called “small strokes” in that their effects are often brief, usually lasting less than an hour. They may come repeatedly over a few days or weeks and are an important signal to seek medical care. Symptoms often include a brief numbness, tingling, or weakness on only one side of the body, or a temporary loss of the ability to speak. Most are caused by a small part of an atherosclerotic plaque breaking off from inside an artery that supplies blood to the brain and then moving “downstream.” When one of these small fragments plugs an even smaller artery in the brain, it is called an embolis. The damage caused by a small fragment of a plaque lodging in a small artery in the brain is usually less severe for two reasons: the artery is small and doesn’t supply a large section of the brain, and the material plugging the artery tends to dissolve within a few minutes.
