Materials and methods: Recommendations were developed based on research of scientific articles (preferentially meta-analyses) and guidelines issued by international medical specialty societies. The American College of Physicians’ Guideline Grading System was used to determine the levels of evidence and grades of recommendations.The following questions were answered: A) Is elective neck dissection indicated in the treatment of papillary, follicular, and medullary thyroid carcinoma? B) When should central, lateral, and modified radical neck dissection be performed? C) Could molecular tests guide the extent of the neck dissection? Results/conclusion: Recommendation 1: Elective central neck dissection is not indicated in patients with cN0 well-differentiated thyroid carcinoma or in those with noninvasiveT1 andT2 tumors but may be considered inT3-T4 tumors orin the presence of metastases in the lateral neck compartments. Recommendation 2: Elective central neck dissection is recommended in medullary thyroid carcinoma. Recommendation 3: Selective neck dissection of levels II–V should be indicated to treat neck metastases in papillary thyroid cancer, an approach that decreases the risk of recurrence and mortality. Recommendation 4: Compartmental neck dissection is indicated in the treatment of lymph node recurrence after elective or therapeutic neck dissection; “berry node picking” is not recommended. Recommendation 5:There are currently no recommendations regarding the use of molecular tests in guiding the extent of neck dissection in thyroid cancer.  \nKeywords  \nThyroid carcinoma; surgical treatment; papillary thyroid cancer; medullary thyroid cancer; follicular thyroid cancer; lymph node metastasis; elective neck dissection; therapeutic neck dissection; molecular tests; indications; guidelines  \n1 Instituto Nacional de Câncer, Ringgold Standard Institution, Cabeça e Pescoço, Rio de Janeiro, RJ, Brasil  \n2 Pontifícia Universidade Católica do Rio de Janeiro, Ringgold Standard Institution, Pós-graduação em Cirurgia de Cabeça e Pescoço, Rio de Janeiro, RJ, Brasil  \n3 Sociedade Brasileira de Cirurgia de Cabeça e Pescoço, Ringgold Standard Institution, São Paulo, SP, Brasil  \n4 Sociedade Brasileira de Cirurgia Oncológica, Ringgold Standard Institution, Rio de Janeiro, RJ, Brasil  \n5 A.
