The physical examination of the thyroid gland involves visual examination, palpation and auscultation, mainly: 1. Visual examination, to observe whether the appearance of the thyroid gland is normal, and to consider goiter if there is a difference in size between the two sides. If the thyroid gland is thickened, press on the thyroid cartilage to check both sides of the thyroid gland, check the texture of the thyroid gland, press to see if there is pressure and pain, and determine if the thyroid gland is smooth or if there are nodules. 3. Auscultation, if you feel an enlarged thyroid gland through visualization and palpation, place a stethoscope on the enlarged thyroid mass, and if you hear a continuous venous buzzing sound, distinguish if it is a murmur of the jugular vein.
