Modified radical neck dissection via extra-thyroideal space (MRND vets) in papillary thyroid carcinoma.

The purpose of this study was to describe an alternative lateral neck access to perform lymph nodes sampling and/or neck dissection via extra-thyroideal space (MRND vets) in papillary thyroid carcinoma with lymph nodes involvment. Twenty-four consecutive patients with papillary thyroid carcinoma were included. Lymph nodes sampling and modified radical neck dissection, unilateral or bilateral, were performed acceding via a lateral dissection through a traditional Kocher incision, running along the medial fascia of the neck, posteriorly to the sterno-cleido-mastoideus muscle (SCM). Mean age was 39.04 +/- 13.69 years. Twenty patients were women, and 4 were men. Mean tumor size was 2.5 +/- 1 cm.. Total thyroidectomy with lymph nodes dissection of the central compartment associated to modified radical neck dissection was performed in 17 patients: among these, nine patients had a preoperative diagnosis of the latero-cervical lymph nodes metastases, and eight had a perioperative diagnosis of metastases of the extensive sampling of the lower third of the jugular chain. Metastatic lymph nodes were found in 107 out of 615 lymph nodes dissected. The MNRD vets access for modified lateral neck dissection seems to carry a lower risk in terms of specific morbility and allows a quicker recovery and a better cosmetic result. This access has to be considered as a less invasive procedure compared to other surgical accesses for the radical modified lateral neck dissection.
