What is the procedure like?
In preparation, you are given medicine to make you feel relaxed. Your cheek is numbed with a local anesthetic. The physician inserts a needle through this tissue. With the help of a video x-ray device called a "fluoroscope," the physician carefully guides the needle to the ganglion. When it is positioned properly, the physician injects the numbing medicine and it bathes the nerves. If these nerves are linked to pain or other problems, you may experience relief. The injection will not cause your face to become numb.
What happens after the procedure?
When the injection is complete, you may be monitored for a brief time and then allowed to leave. Because pain relief may not happen right away, you may be asked to track your pain levels after the procedure.
