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.

Is the number of smokers increasing or decreasing

I don't see as many people smoking as I used to. Are people smoking less? 

Yes, the number of both men and women smokers has decreased dramatically in the United States since the mid-1960s, when public health messages on the hazards of smoking began to reach the general public. Smoking has declined in the United States by about 35 percent since then. There are currently around 40 million ex-smokers in this country. In some states, like California and Utah, less than 18 percent of adults now smoke. While in the United States smoking is declining, this is not true for other countries where greater affluence is linked to more smoking, and where the awareness of the risks of smoking is not as great.
