METHODS: Cross-sectional anatomical study conducted in 28 non-preserved cadavers. RESULTS: The mean number of lymph nodes found in each nodal level of the 56 modified radical neck dissections performed were: level IA -1.5 (95% CI: 1.1 -1.8), level IB -2.5 (95% CI: 2.1 -2.9), level IIA -7.2 (95% CI: 6.0 -8.5), IIB level

CONCLUSION: The results defined a parameter in relation to the minimum recommended nodal yield in a modified radical neck dissection, as well as the number of lymph nodes in each level of this dissection, performed in clinical practice.
