The thyroid gland is found inferior to the larynx and just superior to the clavicles on either side of the trachea. It consists of two lobes connected by an isthmus. Palpate the gland using a bimanual technique where one hand supports the tissue and the other hand palpates the gland on one side and then the reverse is done to examine the opposite side of the gland (Figure 21).
The normal thyroid gland should not be visible and is most often not palpable. In addition, the area surrounding the gland should elevate smoothly and symmetrically during swallowing (Figure 22).
Any variation from these normal findings should be discussed with the patient and the patient should be referred to their physician for further evaluation.
