YouTube Video on Robotic Thyroidectomy Which Eliminates Neck Incisions

Surgeons in Texas have uploaded a YouTube video showing a thyroidectomy being performed by a robot under surgeon guidance without making any incision on the neck. The robot is utilizes the DaVinci system.

Non-robotic thyroid surgery can be seen in this video here which does use a neck incision.

Needle Biopsy of Thyroid Masses Misidentifies 50% of Thyroid Cancers!

Surgeons at the University of Wisconsin found that fine needle aspiration biopsy (FNAB) in 26 of 52 FNAB reported as benign (50.0%) turned out to be either neoplastic (22) or malignant (4) on final pathologic analysis after thyroidectomy. Among patients with nondiagnostic FNAB results, the risk of malignant neoplasms was 27.3%.

Even for smaller thyroid masses, FNAB is still not 100% accurate with a falsely negative rate of around 10%. Why is that?

Well, one must keep in mind that the FNAB samples (or removes) only a tiny tiny tiny part of the thyroid mass (think of a needle going into an apple and trying to hit the worm in the middle). Should the needle sample a part of the thyroid cancer mass where no cancer is present, it will come back normal, even if it is truly cancer.

What does this mean for a patient with a thyroid mass?

1) The ONLY way to know 100% whether a patient has thyroid cancer or not is to remove the thyroid.
2) IF the FNAB shows thyroid cancer, total thyroidectomy is recommended.
3) IF the FNAB does not show thyroid cancer, thyroid cancer can STILL be there; it's just that the FNAB was just plain wrong. Thyroid lobectomy should still be considered.

Of course, one needs to talk with your local surgeon on what the next step is.

Just keep in mind that the FNAB is not 100% accurate!

RANDOM: Michelangelo's David Statue Has a Goiter???

So, I was looking at a picture of The David statue by Michelangelo standing in front of the Palazzo Vecchio when I noticed something on the neck... a bulge just off the midline and below the thyroid cartilage. Could it be a thyroid goiter or mass?

If David was alive today, I most definitely would obtain a thyroid ultrasound and perhaps a fine needle aspirate if a nodule was found. Thyroid cancer would be the concern I would counsel David about.
