The surgical management of papillary thyroid carcinoma remains contentious and the optimal surgical strategy has not been yet established. The extent of thyroid resection has been the nub of this debate. Literature lacks prospective randomized controlled trials that could help put this debate to rest, and these have been labeled as being impractical. Consequently, large retrospective studies and expert opinion have constituted the basis of clinical practice guidelines. Recent American Thyroid Association and National Comprehensive Cancer Network guidelines consider a conservative approach in the form of a thyroid lobectomy sufficient for low-risk disease and that total thyroidectomy remains the standard of care in the presence of high-risk features. Nevertheless, many authorities still advocate more aggressive therapy for low-risk disease. The challenge in standardizing the surgical strategy to papillary thyroid carcinoma is mainly related to a major tumor characteristic: the high frequency of occult cancerous foci whether within the thyroid gland itself or within loco-regional lymph nodes as this tumor characteristic has been incriminated for a higher risk of recurrent disease and its adverse sequelae. The purpose of this article is to provide an overview of the surgical management of papillary thyroid carcinoma and the main arguments surrounding this hotly debated topic. All evidences for this review article were drawn from PubMed articles in English language mostly cross-referenced with international guideline statements.
