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 high blood pressure caused by stress?

Can even minor stresses raise blood pressure? 

Yes. Just think of all the minor stresses that can be found in a day, from being stuck in traffic to conflicts at work. One example we have all experienced, and one that reminds us how even minor stresses can raise blood pressure, is a visit to a physician’s office. In the medical world this is called white coat hypertension. Blood pressure measurements taken in that situation are usually higher than the true average blood pressure, unless the patient has had a chance to rest and relax. This is why at least three measurements are taken in research projects on blood pressure. The patient rests in a quiet environment for a minimum of two minutes after each measurement. Not surprisingly, the last measurement is usually much lower than the first.
