Continue walking down until you reach the next well defined tracheal ring. Now slide the three fingers of both hands to either side of the rings. The thyroid gland extends from this point downwards for approximately 2-3 cm along each side. The two main lobes are connected by a small isthmus that reaches across mid-line and is almost never palpable. Apply very gentle pressure when you palpate as the normal thyroid tissue is not very prominent and easily compressible. If you're unsure or wish confirmation, have the patient drink water as you palpate. The gland should slide beneath your fingers while it moves upward along with the cartilagenous rings. It takes a very soft, experienced touch in order to actually feel this structure, so don't be disappointed if you can't identify anything.
