The left submandibular area is just under the left jaw bone -- not usually near the thyroid. A complex cyst (anywhere in the body) means part fluid, part solid. Would ask your doctor about the location. Rarely would the thyroid extend up that far.
Hey, your report sounded like mine. Do you have any symptoms? Pain when eating? Pain undern the jaw line?
They just removed my submandibular gland last week, along with a lymph node that was piggybacking on it, and a calcified ligament that runs from the back of the right ear to the bottomw of the jaw line. There was not any blockage in the submandibular gland to cause it to enlarge or be painful, to be honest they do not know what they removed. They removed it for two reasons; very painful, and the complex nodule had grown in size. What size is the nodule? I knew mine was not thyroid related because I had my entire thyroid removed 14yrs ago. What are the recommendations on your report? Make sure they keep an eye on it incase it grows.
