Controversies in the management of thyroid nodule.

Few subjects in surgery have generated as much controversy as the management of thyroid nodule. The controversial issues include classification and histology, diagnostic evaluation including needle biopsy, indications for surgery, management of incidentalomas of the thyroid, the role of frozen section, extent of thyroidectomy, management of neck nodes, the role of suppressive therapy, the use of radioactive iodine, and appropriate follow-up. The two major issues in relation to the controversies are diagnostic workup and extent of thyroidectomy. Whenever the issue related to extent of thyroidectomy is discussed, there are two strong groups believing in total thyroidectomy or less than total thyroidectomy. This has generated considerable debate and panel discussions, and this article reviews this on-going debate.
