摘　　要：Papillary thyroid carcinoma(PTC)has a high propensity for regional metastases,however,the impact of such metastases on the outcome of the patients is minimal.The central compartment of the neck is considered the first and the most common echelon of metastases from thyroid carcinoma.Physical examination along with ultrasonography are the gold standard pre-operative evaluation of patients with PTC.Ultrasonography is highly sensitive in evaluating lateral neck nodes,however,its value in evaluating the central compartment is limited,resulting in a relatively high rate of occult metastases in this compartment.The main potential complications of para-tracheal neck dissection(PTND)are recurrent laryngeal nerve paralysis and hypocalcemia and these may be higher in patients undergoing PTND compared to thyroidectomy alone.New histological data is available showing no evidence of lymph nodes in the central compartment above a level parallel to the inferior border of the cricoid cartilage.These findings support withholding dissection of the upper para-tracheal region routinely as a part of PTND in patients with well-differentiated thyroid cancer.By doing that,the complications may be lower and identical to thyroidectomy alone,thus may abolish arguments against more common use of elective PTND in patients with thyroid carcinoma.
