Central neck dissection: updates on indications and surgical technique

Abstract

This article aims to describe the indications, pertinent anatomy, and surgical technique of the central neck dissection (CND) as it pertains to carcinomas of the thyroid gland. Further discussed are major complications of the procedure and factors considered in surgical decision making. Therapeutic CND is strongly recommended and widely performed in patients with clinically or radiographically evident nodal disease; however, elective/prophylactic CND requires an informed decision that should be based upon patient specific disease and risk factors. If able, CND should be performed concurrently at the time of thyroidectomy to minimize risk of injury to critical structures such as the recurrent laryngeal nerve and parathyroid glands. When indicated, CND performed by a skilled surgeon reduces the risk of locoregional recurrence and is associated with low overall morbidity.
