Ywata de Carvalho and associates performed a retrospective study of 580 patients with papillary thyroid cancer without lymph node metastases between 1996 and 2007 to evaluate prophylactic neck dissection (level VI). Group A included 102 patients who underwent total thyroidectomy with elective neck dissection, and Group B was the 478 patients with total thyroidectomy only. Group A sustained higher rates of complications, temporary and permanent hypocalcemia, and temporary and permanent recurrent laryngeal dysfunction. Despite the high rate of nodal metastases in a selected group, the authors found that elective central neck dissection increased complication risk without decreasing local recurrence rates.
