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.

How are X rays produced?

How are X rays obtained?

Most X-ray diagnostic studies of the stomach, intestine, gall-bladder, chest, kidney, bones, and skull can be obtained on an ambulatory basis. They are performed by an X-ray specialist (radiologist) in conjunction with a trained technician, who actually develops the film. The techniques of the examination and the interpretation of the findings are the province of the radiologist.
The X rays are taken in the radiologist's office or on a comeand- go basis in the radiology department of a hospital or a group clinic. These films are loaned to the surgical consultant for his evaluation. However, certain elaborate X-ray examinations, such as those that follow injections for visualizing the blood vessels, should be done only with the facilities and precautions that are available to a patient within the hospital. The disadvantage of hospitalization is that, incongruously, it may actually take longer to get the studies completed. Furthermore, some hospital insurance plans do not cover diagnostic studies.
