1. Unlike follicular thyroid carcinoma, which spreads hematogenously, papillary and medullary thyroid tumours frequently expand to regional lymph nodes. Prior to surgery, it is important to perform a thorough examination of the central compartment (level VI) and the lateral neck (levels II–V). Dissecting the neck beyond the central compartment for cosmetic reasons is controversial. In cases when the cancer has advanced to the side of the neck but there is no visible illness in the central part of the neck on imaging, a total thyroidectomy should be performed alongside an ipsilateral central neck dissection. Thyroid cancer surgery can often maintain level I (the submandibular gland) since it is rarely affected by locoregional metastases.
