Nomogram for Predicting Difficult Transoral and Submental Thyroidectomy

This study is building a prediction tool (called a nomogram) to help surgeons identify which thyroid cancer patients are likely to have a more difficult time with a minimally invasive, scar-reducing type of thyroid surgery done through the mouth or under the chin. **You may be eligible if...** - You have been diagnosed with a type of thyroid cancer (differentiated thyroid cancer) with a tumor no larger than 4 cm - There is no sign of cancer spread to distant parts of the body or suspicious lymph nodes in the side of the neck - You care about minimizing visible scarring from surgery - You underwent total thyroid removal with central lymph node dissection **You may NOT be eligible if...** - Your lymph nodes in the neck are fused together or fixed in place - You have had previous neck surgery or neck radiation - Your vocal cords are already affected - Imaging suggests the cancer has grown outside the thyroid - Your neck movement is significantly restricted Talk to your doctor to see if this trial is right for you.
