Total thyroidectomy versus lobectomy in conventional papillary thyroid microcarcinoma: Analysis of 8,676 patients at a single institution.

Abstract

Because there is a controversy regarding the management of papillary thyroid microcarcinoma, the purpose of this study was to compare lobectomy with total thyroidectomy as a primary operative treatment for papillary thyroid microcarcinoma. Loco-regional recurrence in the contralateral remnant lobe can be managed safely by completion thyroidectomy via the previous scar. However, reoperation for operation bed (thyroidectomy site) or regional lymph node (central or lateral) recurrence generally is associated with morbidity. Therefore, we analyzed overall loco-regional recurrence and loco-regional recurrence outside of the contralateral remnant lobe separately.
