Abstract: Objective: To discuss the multifunctional conservative neck dissection in the treatment of thyroid papillary carcinoma. Methods: The data of 52 patients with thyroid papillary carcinoma were analyzed for the operational technique in multifunctional conservative neck dissection preserving cervical plexus retrospectively. Results: In the group, the rate of lymph node metastasis was 66%. There were no impairment of sensation of ears and lower necks and upper shoulders and no muscles of neck atrophy. Conclusions: The preservation of cervical plexus in the multifunctional conservative neck dissection for thyroid papillary carcinoma does not increase the recurrence of the lymph node metastasis. However, it can protect the sensation of ears, lower necks and upper shoulders.
