Surgery versus pharmacotherapy of benign thyroid diseases

Abstract

Surgical management of benign thyroid diseases (BTDs) has been a topic of interest and confusion for many years. Almost 80% of thyroidectomies at an average endocrine surgical unit are carried out for BTDs. Resistance to surgical intervention in BTDs has been based on the belief that increased complication rate is inherent in its use, this is despite the potential advantages in terms of confirming the benign nature of the lesion, controlling the disease, and relieving local symptoms of large neck mass. Benign thyroid diseases are more likely to occur in middle-aged women living in iodine deficient areas, or have a family history of goiter, or in patients taking iodine-containing drugs, like amoidarone, or in patients with previous history of x-ray exposure. However, the physician must be careful in making the diagnosis of BTDs in patients at the extremes of age or in the presence of positive history of radiation, or in patients with family history of thyroid or colon cancer. In this article we will review the etiology, epidemiology, diagnostic methodologies and the recent trends in the surgical and medical management of BTDs.
