What is a radical neck dissection? when is it done?

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.

What is biofeedback and how does it work?

What are stress interventions? Can they be helpful?
An intervention is something that “comes between,” in this case, something from outside yourself that comes between you and your stress. Biofeedback is both a diagnostic and therapeutic tool that can be used to evaluate some of your physiological stress responses, and it can also help you to change them. A technician hooks you up to a biofeedback machine, which uses sensors to monitor your body temperature, muscle tension, brain wave patterns, blood pressure, or heart rate. By learning to recognize which sensations are correlated with body temperature, for example, you can learn to raise and lower the temperature in your extremities by dilating and constricting your blood vessels. You can also learn to tense and relax muscles voluntarily, and to enter different brain wave states at will. Some people learn to control their blood pressure and heart rate to some extent. These skills can be very valuable in inducing relaxation.
