ABSTRACT
Despite its small size, the thyroid gland plays a key role in modulating and coordinating a wide variety of metabolic processes within the human body. Although many of the diseases involving this organ can be managed nonoperatively, the surgeon is frequently consulted when swallowing or breathing is adversely affected by an enlarged gland, or when a solitary module is thought to be potentially malignant. Thus, a thorough knowledge of the pathophysiology of this gland is mandatory if correct decision-making is to occur when surgical interventions are being considered. This chapter attempts to provide that understanding.
