Abstract：Cervical lymph node metastasis is common in papillary thyroid carcinoma (PTC).Standard cervical lymph node dissection is helpful to reduce local recurrence rate,reoperation rate and improve the prognosis for PTC patients.However,the anatomical structure of the neck is complicated.Metastatic lymph node is easily missed during surgery without careful preoperation evaluation,standard dissection extent and skilled surgery technique resulting in the lymph node residual.Lower central lymph node,lymph node posterior to right recurrent laryngeal nerve,level Ⅱ b,deeper lymph node of level Ⅳ,level Ⅴ,lymph node between nerve root intersection,lymph node between sternocleidomastoid and sternohyoid muscle and pharyngeal lymph node are the most common missed locations during cervical lymph node dissection.Preoperative enhanced CT is helpful for the diagnosis and localization of metastatic lymph node.Familiar with the location of missed metastatic lymph node,accurate preoperation evaluation,standard dissection extent and skilled surgery technique are the key points avoiding lymph node residual during cervical metastatic lymph node dissection.
